Olanzapine --- Nursing Care

In this essay, I would be reflecting a case in which better health outcome was achieved using an antipsychotic drug called Olanzapine. While identifying the issues of the service user, I ensure that confidentiality will be maintained and so pseudonyms will be used instead of the full name corresponding to the Nursing and Midwifery Council (NMC 2008).  All the decisions will be justified and the choice of medicine proportionate to the health promotion will also be discussed. The essay will also talk about all the possible mechanism, pharmacokinetics and pharmacodynamics of the chosen medicine along with the possible adverse effects. The health outcome of the use of the drug and any recommendations for future will also be considered.  The conclusion will revolve around the evaluation of the outcome of the drug of choices administered.
Case Study
Kate, a 56 year old female with previous psychiatric history of schizophrenia presented with the marked deterioration in her health.  She was at present using haloperidol and sodium valproate twice daily.  Kate was examined thoroughly. She was though conscious but now having more auditory and visual hallucinations. She also felt difficulties in working and concentration. She answered all the questions well but also showed auditory hallucination and told that someone is talking with her, let her answer her too. She was admitted the psychiatry ward. Her current medications were asked to stop and instead Olanzapine was started. She was asked to be currently monitored. Once her condition became stable, she was discharged but asked her to use this medication regularly. She showed concordance that she will follow all the instructions and take the medication regularly.  She was also explained about her condition and shown full sympathy and ensured her that she would feel fine. She was also called for follow up after few days.
After few days, she came for follow-up and was found to be feeling much better and there were also improvements in her auditory and visual hallucinations. She also reported herself that she is feeling well now.  Olanzapine was found to be suiting more and thus, she was asked to continue this medicine.
General Background About Schizophrenia
Schizophrenia is basically a mental disorder characterised by the disturbances in thinking, behaviour and feelings. People often report visual and auditory hallucinations. Some may report delusions and disorganized speech. This serious mental illness disturbs the individual’s aptitude to think evidently, deal with sentiments, and decisions making. It is the result of changes in the brain structure and brain chemicals. It is a chronic condition of complex nature and affects different persons differently. The treatment of schizophrenia may involve all-encompassing strategies including medication, psychotherapy and even psychosocial rehabilitation.
It is believed that clinical expertise is very important in selecting and managing drug therapy for a patient. It usually entails an understanding and knowledge of the research evidence involving the effectiveness, efficiency and efficacy of the choices poised with concern of the clinical situations of the patient (Morris, 2002).
What is Olanzapine?
Olanzapine is from the group of drugs known as antipsychotics. It is basically an atypical antipsychotic and is one of the members of thienobenzodiazepine category. The U.S. Food and Drug Administration (FDA) has approved it for the treatment of conditions like bipolar disease and schizophrenia. It treats the symptoms of schizophrenia and linked psychoses with this disease (Duggan, Fenton, Dardennes, et al 2003).
Mechanism of Action of Olanzapine
Though, the correct mechanism via which olanzapine provides it antipsychotic effect is not known, yet, this effect is believed to be caused by its antagonism for both the serotonin 5-HT 2 and dopamine. Olanzapine offers selective monoaminergic antagonist and it has a strong affinity for four dopamine receptors as well as for serotonin 5-HT 2C and 5-HT 2A receptors. However, its affinity for benzodiazepine (BZD), gamma-aminobutyric acid type A (GABA A), and beta-adrenergic receptor is very low (Citrome , and Volavka 2003).
Olanzapine also show high affinity towards all the muscarinic receptors such as M 1, M 2, M 3, M 4, and M 5. However, it behaves as an antagonistic to these receptors. Due to the antagonism, the anticholinergic effects are observed with the use of Olanzapine. Moreover, Olanzapine has also shown to bind with an elevated affinity to alpha 1-adrenergic and histamine H 1 receptors.  Due to antagonism to these receptors i.e. alpha 1-adrenergic and histamine H1 receptors, orthostatic hypotension and somnolence may occur respectively, with the use of olanzapine (McEvoy, Lieberman, et al 2006).
Pharmacokinetics

Though, olanzapine is well absorbed yet about forty percent of drug is metabolised well before it reaches the systemic circulation. Food does not affect the rate of absorption of this drug. Also, it has been found that antacids (magnesium and aluminum- -containing) also do not affects its oral bioavailability.  This drug is broadly distributed all the way through the body.

Laser material processing methods



A set of laser material processing methods can be used for fabricating configurations in the nanometer and micro scale length domains. Laser beams are at present being utilized for a variety of processes such as surface modification, fixing, and accuracy machining, etc. for the last couple of decades the laser particularly the its processes have been shown where the employ of the intrinsic lasers properties has brought about a high dependability in the processing of materials.

These established processes frequently use ingenious approaches that depend on derived facets of recognized most important principles that ruled laser/material interface phenomena. The surface state of a component is generally the chief engineering factor. Approximately unavoidably the external surface of a work-piece is exposed to corrosion and wear while it is operational. The aim of this overview is to look at the three effects of the laser processes and techniques that could be used n industry owing to the requirement for better accuracy, elevated resolution, fabrication, etc. These three effects include power density distribution, travel speed and total heat input.

Ovarian factors--- Infertility Causes-- Literature Review

2-2-3. Ovarian factors
Ovarian disorders are found in approximately 15% of all infertile couples and more than 40 % of unproductive female. (Saravelos, Cocksedge and Li 2008.). An obvious symptom of this disorder will be the disturbance of the menstrual cycle. However, it may be more subtle. The cause should be sought out and diagnosed critically because there is a specific treatment for the different types of disorders. The most common causes of ovarian disorders are the poly cystic ovarian syndrome (PCOS), obesity, weight loss, prolactinemia, thyroid dysfunction, and difficult doing exercises, (ASRM 2012)               








 
    The conception cycle is defined by preovulatory follicle measured 18 mm or more in size , many irregular cycles are caused by insufficient leuteal levels which may be a result of follicle rupture failure, empty follicle, and follicular retention (Healy et al 1994). It is possible for the normal female with normal menstrual cycle to have PCO and consequently low rate of fertilization and decreased opportunity for getting pregnant. Catteau-Jonard et al (2012), they found that, the PCO detected in 21-63% of the women were actually normal. Women with normal ovulation are generally connected to the normal monthly cycle, and ovulation disorder provides a history of oligomenorrhea or amenorrhea. This will be one of the causes of infertility due to ovulatory dysfunction; this disorder may be related either to the hypothalamicpituitary or due to the disorder of the ovary itself.  Hypothalamic-pituitary dysfunction may cause no or low levels of several hormones such as GnRH, FSH, and LH, resulting in an onset of ovarian disorders and anovulation. On the other hand, conditions such as ovarian tumor, ovarian failure and Turner syndrome may prevent the pregnancy by changing ovarian responses to the hormonal signalling leading to the infrequent ovulation (Harris et al 2013). Broekmans (2009) identified that lower level of ovarian reserve, infertility and early age of menopause may occur as a result of loss of oocytes before maturity.  The diminishing of oocytes quality related to the elevation of meiotic nondisjunction is associated with women age, this diminution of follicles quality decreases women opportunity to get pregnant. Ovarian reserve refers to the follicle and these follicles remain in the ovary at any specific time, including a number and quality of the follicle. This should be considered to provide evidence about the women ability to conceive. The ovarian reserve decreases gradually with age and when the age of menopause is achieved only very few follicles remain (Harris et al 2013). This decline of the follicle refers to both quality and quantity of the available follicle, therefore ovarian aging should always be considered as a differential diagnosis for ovarian disorders in the infertile women. Advanced age and history of previous ovarian surgery also present as the risk of ovarian dysfunction or diminishing of the ovarian reserve (Quaas and Dokras 2008). Before more than 60 years, PCOS was discovered as a common entity, the researcher identified that PCOS is a genetic disease (Legro andStrauss 2002). It is thought that the PCOS causes infertility as a result of elevated luteinizing hormone and androgen levels, which leads to the interruption of folliculogenesis and anovulation. It is believed that the pathophysiology of PCOS caused by several factors include,, hyperandrogenemia,  hyperinsulinemia, obesity, and elevated steady-state LH levels. However, the exact process behind this syndrome is still unknown and requires being investigated (Harris et al 2013).
2-2-4.Other factors
There are several factors that should be considered while performing the assessment of infertility, which could be identified as a cause of unexplained infertility. The first factor is the women age. Age is recognised as one of the important causes of female infertility, infertility increased gradually with age for both male and female, but it is more pronounced in female of age more than 40, when the chance of pregnancy declined to only about 5% per month with a spontaneous miscarriage rate of 34%to 52% (Denson 2006). The second risk factor was the implantation failure. The traditional knowledge of this concept as a cause of infertility is that the insufficient secretion of the progesterone may cause non -respective endometrium for the nidation of the bastocyst resulting in failure of pregnancy (Healy et al 1994). Third was the recurrent miscarriage, one third of women with recurrent abortion may have found to suffer from infertility, however, there is a little doubt regarding the connection between the repeated pregnancy wastage and infertility since two third are able to achieve pregnancy. The forth risk factors was the lifestyle factors which include nutrition, sports, clothing, alcohol drinking, tobacco and drugs. Fifth risk factors were psychological and occupational factors. A link is thought between the stress, anxiety and depression with infertility. However, the exact role of these conditions is still uncertain. The occupation also has a potential effect on the couple infertility. Occupation associated with high exposure of textile dyes, lead, and cadmium are the most important risk factors. These factors mostly find in women, who have unexplained infertility. Sixth risk factor was the male infertility, which may be as a result of obstructions of the duct or abnormalities of sperm production or the physiology of the sperm (Denson 2006). This study will not cover all these factors but will mainly concentrate only on the diagnosis and management of the female pelvic factors including uterus, tubal and peritoneal, and ovulatory factors, and understanding of these factors and causes of infertility along with identifying of the initial fertility assessment. These will possibly be used as a guide to formulate the diagnostic plan.

Literature Review --- Infertility

2 Literature Review
2.2 Aetiology
The causes of infertility are variable with regard to the social and demographic profile of the individuals. The WHO provides a statistical analysis about the causes of infertility.
This study will concentrate mainly on the female pelvic causes of infertility rather than including all the general causes.
2-2-1.Uterine factors
Uterine factors represent 2-3% of the incidence of infertility and intrauterine pathology is the much more common in infertile women (40-50%) (Niknejadi & Haghighi 2012), therefore, female reproductive tract should be examined for any probable causes of infertility first part of the reproductive tract is the cervical canal. An irregular cervical mucus component, which interacts with the sperm, is not often regarded as one of the leading causes of infertility. However, the postcoital test (pct), the measurement and observance of the presence of the active sperm in the cervical mucus is still one of the infertility evaluation tests. Coussein and Vlahos (2012) identified that the uterine abnormality is relatively uncommon causes of female reproductive failure. Uterine malformation caused by mu¨llerian fusion defects are the most common types of congenital anomalies of the reproductive system (Homer et al 2000). This type of anomalies may occur during the Mu¨llerian developmental process (Saravelos, Cocksedge & Li 2008), (Wold, Pham, and Arici 2006). Furthermore, American Society of Reproductive Medicine developed specific calcification of the uterine malformation regarding the degree of failure of development of the Mu¨llerian duct. This calcification has become the most widely accepted and used globally, their calcification consist of seven regions 
(1) Mu¨llerian hypoplasia which may include the vagina, the cervix, the fundus, the tubes, or combined
 (2) Unicornuate uterus hypoplasia of one of the two Mu¨llerian ducts and this could be subdivided according to the present or absence of the rudimentary horn
 (3) Didelphys uterus (failure of lateral fusion of the vagina and uterus Mu¨llerian ducts)
(4) Bicornuate uterus (incomplete fusion of the uterine horns at the level of the fundus), which may be partial or Complete.
(5) Septate uterus (absent or incomplete resorption of the uterovaginal septum), ether Complete or Partial
(6) Arcuate uterus (a mild indentation at the level of the fundus)
(7) Diethylstilbestrol (DES) exposed uterus (T-shaped uterus resulting from DES exposure of the patient in utero)
Inthis calcification, there is no specific procedure or criteria for the diagnosis of each anomalies and the result will depend on the clinician impression (Woelfer et al 2001).It is important to know that this calcification exclude some of the other anomalies such as cervical atresia, vaginal anastomosis and vaginal septum (Pavone et al 2006).The diagnosis and indications for the treatment vary according to the different types of malformation. The septet uterus is the most common uterine anomalies among the other kind of anomalies (Homer et al 2000).
Figure F1    Calcification of the uterine malformation according to the American Society of   Reproductive Medicine ( Lee & Ku 2011).
Repair of these Müllerian anomalies or Caesarean section may result in synergy Uterine synechiae or uterine atresis and these can be defined as the presence of intrauterine adhesions (IUAs) or combined of fibrotic tissue can be either partial or complete (serious and severe adhesions resulting in menstrual dysfunction and infertility) (Ahmadi & Javam 2014).Imaging methods used in the diagnosis of these anomalies will be discussed in details in the next section.

2.2.2. Tubal-peritoneal factors.
In about 25–35 % of women, the risk factors for infertility are the result of the tubal peritoneal pathology. Pelvic inflammatory disease (PID) is the most common disease .In more than half of the these cases, tubal peritoneal factor infertility may occur as a result of ectopic pregnancy, pelvic PID, endometriosis, and pelvic or adnexal adhesions.  These factors may reveal some sort of pathology but cannot adequately specify the diagnosis (Coussein and Vlahos 2012). The outer end or ampullar section is responsible for Fertilization and the Fallopian tubes are responsible for oocyte uptake. For this reason, any change in anatomical or physiological aspect of the tubes is usually associated with the cause of the infertility. For example, contraceptives have a certain effect on fertility.  Brugo-Olmedo, Chillik and Kopelman (2002) also emphasised on this fact that there is an association between endometriosis and infertility.   Their study demonstrated approximately 48% infertile patients were found to have endometriosis compared with 5% of the normal fertile patient.Also, another study also found that 30-50 % of the patient with endometriosis were infertile (Bulletti et al 2010).  Endometriosis is actually the condition which is identified as the presence of endometrial tissue, stroma or glandes out of the uterine cavity, which leads to the onset ofchronic inflammatory reaction. It may affect about5-15% of women in their reproductive period.  Bulletti et al (2010) did an extensive research to explain the relation between infertility and endometriosis. They found that the prevalence of infertility in the females with endometriosis may relate to several situations such as anatomical disorders, anovulation and changing of the luteal phase. Abrao (2013) was also of the similar opinion. Some authors have identified that the changes in receptivity of endometriosis may affect on uterine implantation

Patient Centered Care

Patient Centered Care

Introduction

Different governmental policies endorse nurses to use each and every reachable chance to encourage the health and wellbeing of patients (Department of Health 2010). Nurses enjoy a unique and distinct connection with patients, which promotes trust that patients can have in nurses. Therefore, it is the essential duty of nurses that they should use their powers and trust to inspire behavioural change in the patients who have poor health due to their unhealthy behaviour about themselves. The most important way for this purpose is to empower the patients by involving them in their care plan. The involvement in any kind of decision making activities and plans will bring positive change in the behavioural response of the patient in health related matters. Moreover, effective problem solving decision and strategies making skill derived from a strong basis of information are behaviours expected from nurses that require to be grown during their professional education. The goal of this assignment is to offer needs or problems orientated approach to care using a nursing process (Taylor 2000).
In this case study, a problem solving approach is used for assessing, analyzing, planning, implanting and evaluating the patient’s problem. The problem of a patient is recognised following a thorough assessment, and then plans are made for her care and implemented and evaluated for the achieved outcomes from the intervention given.
Case Study
Mrs Thomas was a 70 year old widowed female living alone in a bungalow which was controlled by the warden. She had 3 children who are all married; however one of them lived in close proximity and also visited often. She was admitted to the Medical Assessment Unit following a fall in her home and was managed using a problem solving approach.
Problem Solving Approach
Fraser (2003) defines a clinical problem-solving approach as a process in which a practitioner extracts pertinent and particular information obtained from patients to assist differentiate between working diagnoses, makes suitable working diagnoses, searches for discriminating and related physical signs to help verify or disprove working diagnoses, properly infers and applies information taken from all sources regarding a patient, puts into practice the knowledge of basic, clinical and behavioural sciences to the detection, treatment and solution of problems of patients and distinguishes limits of competency and responds properly. This approach is utilised below for Mrs. Thomson.

Assessment
Once Mrs Thomas was comfortable, the nursing assessment was begun. An assessment is basically the compilation of information from a person, to establish their requirements and develop an obvious potential of their situation. This process depends on thorough and complete assessments to be a success. An important nursing skill is monitoring a patient, via all five senses, from hearing to enhance information, to feeling them via a touch, assessing their body temperature and their skin condition (Brooker and Waugh 2007). Holland et al (2004) is also of the opinion that an assessment recognises the main concern amongst the problems.  This necessary information can be gathered in a number of distinct ways, from watching a patient, examining, and communicating with them. Gathering of information can also be made via a relative mean if, for instance, the patient who is the primary source is comatose or unconscious. Information can be obtained from the patient, the friends or family of patients and even from the health records or evidence (Peate 2010).
Further, in order to carry out a full assessment different assessment tools were used based on Mrs Thomas clinical presentation. Her assessment was carried out by her bedside and in order to respect her privacy the curtains were drawn out. The assessment needs to be carried out appropriately and correctly.  Barrett et al (2009) states that nurses who perform incomplete and disordered assessments, may not be successful in finding a major problem, or seeing an underlying issue. Assessment is the keystone on which a patients care is designed, applied and assessed (Roper, Logan, Tierney 2008)). Sutcliffe (1990) also stated that incomplete or poor assessment consequently causes poor care planning and execution of the care plan. Therefore, in order to carry out a precise assessment full concentration was made following all the standards.
Physical examinations revealed the presence of bruising to the left side of her face, and her upper and lower body. She also complained of a general, non-specific soreness of the whole body and headache. There was a problem of urinary incontinence, and her urine also smelled offensive. However, there was no other significant past medical and surgical history.
A number of risk assessment tools were used when assessing Mrs Thomas. These were the waterlow score, malnutrition universal screening tool (MUST), activities of Living and falls risk assessment score. The waterlow score helps to find out whether there is a possibility of developing a pressure ulcer in a patient or not (Waterlow, 2005).The MUST tool is a screening tool for nutritional assessment that identifies under nutrition and over nutrition (obesity) in a patient (BAPEN, 2008). Activities of living model is basically a tool comprising twelve activities that are intended to maintain a normal living, and include communication, eating and drinking, breathing, keeping a safe environment, personal cleansing, excretion, body temperature control, dressing, playing, working, mobilising, sleeping, expressing sexuality, and eventually dying. All of these activities are vital. However, these are affected by the illness. The fall assessment tool is to evaluate if a patient is at danger of a fall, taking into consideration their history as well as their present condition (Hendrich 2013).
Mrs Thomas was assessed using MUST initially and she was found under weight with BMI 18. She was then assessed using waterlow score because she is at high risk of developing pressure ulcers. Mrs Thomas was assessed and given a point value through these regions such as type of skin, visual risk areas, build or weight for height, mobility, malnutrition screening tool and continence. The score came out to be greater than 10, showing a greater risk of developing an ulcer.
On further assessment, she was found to be suffering from cognitive impairment and was also disorientated to time and place. 12 activities of living were assessed as proposed by Roper et al (2008). She was found to be socially active and independent with a good circle of and contact with friends. She also used to attend local events and did her shopping weekly with her daughter.
Objective and subjective data both were collected during the assessment from Mrs. Thomson. The objective data collected such as blood pressure and temperature were recorded and were found in satisfactory limits.  In order to take a subjective data Mrs Thomas was taken in complete confidence that her all details would be kept confidential so she could share anything she wanted to. She was explained that a complete detail will help us in recognising her problem and therefore treating it onward. She told that she used to be a happy person but now she felt her loneliness and remained sad. Therefore, she didn’t feel like eating or doing anything. Her problem was then analysed to reach some particular nursing diagnosis.
Analysing
Based on her complaints, assessment and physical examination, a nursing diagnosis was made. The nursing diagnosis considers the medical diagnosis in addition to the holistic requirements of the patient taking into consideration their spiritual and biopsychosocial necessities and the consequence these may exert on the patient and how they cope with their disease (Hinchliff et al 2008). This also facilitates the nurse to interpret the information achieved during the assessment and recognise the nursing problems (Lunney et al 1997).
Nursing diagnosis is an important action in the nursing process; it counts on a precise and complete nursing assessment and makes the foundation of nursing care-planning (Minton, & Creason 1991). It is the end result of nursing assessment, a lucid declaration of the patient’s problems as determined from the process of assessment (Roper et al., 2008). In this case, four potential diagnoses were made i.e. Depression, Urinary tract infection, A potential risk of development of pressure sore and Malnutrition.
A diagnosis of depression was based on her feelings of loneliness, for which she left eating, enjoying and taking part. Since she left eating, she became underweight, and therefore malnutrition was also diagnosed. She was suspected of suffering from urinary tract infection and this might have lead to delirium. Pressure sore was already evident on her sacrum and it might be lying on a floor after a fall for a long period of time.
Planning
The next step was the planning. The planning step of the process is where attainable objective needs are made via discussion with the patient and or his care givers (Benner, Tanner and Chesla 1992). This step is therefore over lapping and interdependent and the success of this step relies on the comprehensiveness and quality of the assessment. The nursing planning is actually where all the information obtained in the assessment part is utilised to plan the patient care. The plan of care is to resolve the genuine problems of the patient (Lunney et al 1997). It also aims to facilitate the patient tackle their disease in an optimistic approach and to make them as restful and free of pain as possible. 
Thus, in order to ensure good planning all the information gathered from Mrs Thomas in the assessing step was utilised here. The planning was done by taking into an account not only the medical diagnosis but also the holistic requirements of the Mrs. Thomson in view of their spiritual and biopsychosocial needs or wants (Hinchliff et al 2008). Holistic approach was focussed in order to ensure psychological, physical, spiritual and social aspects of the Mrs Thomas (Meurier, 2005).
Setting plan or goal is important for the wellbeing of the patient. It plays a role as a spur for the patient and persuades them to work towards this (Kemp and Richardson, 1994). The more the information collected in the assessment, the simpler is to make the plan of care. The chief aim of a nursing plan is to offer the information on which individualized, systematic care can be based. Nevertheless a comprehensive individualized care plan for a particular patient needs to be capable to perceive exactly what is mandatory for the patient, the NMC (2008) stats that nursing interventions should be specific for the particular patient, anchored in best evidence, quantifiable and attainable.
In order to plan a care, there are a lot of diverse principles for setting goals. One of these is patient centred, observable, directive, and quantifiable, recordable, comprehensible and lucid, convincing and time related principle (Roper et al 2008). When planning a care a much emphasis needs to be rooted in the independence or dependence continuum established in the assessment stage.  The care should be such that it encourages the patient to revert to as practically possible to his/her healthy life.
The basic goal was to first correct the present condition of the Mrs. Thomson. Afterward, the plan was made to correct the real cause behind her present situation and complains. The third aim was to keep her engage in meaningful activities. I believe this is one of the essential elements of care.  Life activities facilitate patients keep up their functional abilities and can even augment quality of life (Lyketsos et al 2000).  The last goal was to help her come out of her depressive thoughts. The plan was to make her feel good in each and every circumstance, either good or bad, in order to live a life happily and free of health related and other problems. Since according to Roper et al (2008) planning should be done considering the resources available to put into practice the care, everything was planned accordingly for Mrs. Thomson. Next important step was the implementation of care plan.
Implementation
This is an important component of the problem solving approach and where all the set goals in the planning step are put into practice and the aims can begin to be attained through medical and nursing interventions (Van Achterberg, Schoonhoven and Grol 2008). The process of implementation is basically the real giving of nursing care. The process of implementation was carried out for Mrs. Thomson not only by nursing staff but also involving the multidisciplinary team including nutritionist, doctor, psychologist and physiotherapists.
In order to manage certain problems certain coping strategies were developed comprising both adaptive and maladaptive strategies. Mrs. Thomson was encouraged for adaptive coping strategies such as emotional regulation, problem solving approach, positive thinking, acceptance, and cognitive reformation and at the same time Mrs. Thomson was discouraged from maladaptive strategies such as feeling bad, negative, depressed, etc.
But before starting the treatment, an informed consent was taken as it is essential since patients are have full right and they should be managed with respect and dignity considering their values, culture, and beliefs (Paterick et al 2008). Therefore, all the implementation of treatment was given after taking an informed consent. After the treatment, a patient felt quite well. She was given a discharge and asked for the follow-up visits.  Following implementation, evaluation was carried out.
Evaluation
The process of evaluation is basically in reality the closing stages of the nursing process (Willms and Sirotnik 1994). Evaluation is where the patient has received the care and now the care given is assessed whether it has worked or not (Vaismoradi, and Parsa-Yekta 2010). It is an ongoing and a constant process and also takes place in a formal background at timed points.
Evaluation can be divided into two different components, the formative evaluation and summative evaluation (Graff, Russell, and Stegbauer 2007). Therefore both the evaluations were carried out on Mrs. Thomson. In formative evaluation information about the independence or dependence continuum of Mrs. Thomson was taken and evaluated. This information was obtained from her as well as from her psychologists and nutritionist. It also involved discussing and noting the issues of Mrs. Thomson either getting improved or worse and finding out if she had moved away or towards from the planned goals. In summative evaluation her holistic opinion was considered i.e. how she felt regarding the treatment; whether he felt that the goals were attainable (Stetler 2006).
Following evaluation of Mrs. Thomson, she was found going well with the treatment. She had adopted many new activities to avoid loneliness. She also showed good compliance with the drugs.
Conclusion
In this paper, the nursing process was carried out on Mrs. Thomson to identify, treat and prevent her potential health problems. The assessment and individualised care planning determined the Mrs. Thomson particular requirements or needs as regards to her health. A holistic approach was the used for her overall wellbeing. Care needs were started out in a manner that both the nurse and the Mrs. Thomson knew precisely what was occurring together with her psychologist, doctor and nutritionists. Eventually, Mrs. Thomson showed an earlier recovery and returned back to her normal and healthy life, -- demonstrating that involving the patients in their care facilitate them to experience they are part of their care team and are more likely to help themselves with their care.
Thus, in problem solving approach in order to make the nursing process effective re-evaluating goals as well as interventions require being ongoing and continuous. This paper has demonstrated that when problem solving approach is used, it offers a first-class basis to providing nursing care.

  Analyse And Compare The Various Forms Of Audiological Support For Deaf People Of All Ages.

Individuals who are hard of hearing or deaf can use a number of technologies that offer them with better accessibility in several environments. The majority of devices either correct hearing, give amplified sound or others means to access information via vibration and/or vision. But the first step is to try to find the services of an audiologist.
What Kind Of Services Do The Audiologists Offer?
An audiologist is a professional specializing in providing services related to vestibular and auditory system of the ear. He identifies, diagnoses, monitors and treats disorders linked to these segments of the ear (Berger, 1976).
Diagnose And Identify Cause Of Hearing Loss: The audiologist is the expert most competent by experience, education and training to evaluate and diagnose certain types of hearing loss, even non-medical. Audiologists present a variety of treatment options to patients with hearing impairment
Work For All Age Groups: Audiologists have extensive education and skills to assess the hearing of people of all age group from adults, children to infants.
Counselling And Hearing Services: Audiologists also offer counselling services to people with hearing loss as well as their families and construct a care plan that often comprises hearing aids and assistive devices. It is vital to understand that hearing aids alone cannot solve hearing loss problem (Schwartz, 2007).
Hearing Testing: They carry out a wide range of tests to find out the accurate cause of a person's hearing problem. Audiologists also examine the eardrum by using otoscope, remove ear wax, perform diagnostic audiologic tests, and test out medically related problems of hearing. They also hand out and set hearing aids, do tests of balance to test dizziness, and offer hearing rehabilitation education.
Referral Patients To Pertinent Expert: When the problem of hearing requires surgical or medical consultation, Audiologists refer their patients to surgeon or physicians, respectively (Berger, 1976)..
Education And Training: Even they conduct clinical research activities with real patients and also teach at medical schools and universities. Audiologists offer training and education so that individuals with hearing impairment can gain from communication and amplification devices.
Hearing Protection Programs: Long-standing exposure to loud noise leads to permanent loss of hearing. Audiologists are often concerned for this problem; therefore work for the prevention of hearing loss by involving themselves in implementing certain programs helpful for protection of the hearing. This protection is especially important for individuals who are exposed to loud recreational and industrial situations or occupation (Berger, 1976). They also work closely with the agencies of the government, practicing medical doctors and hearing aid makers for prevention as well as management of hearing loss causes and diseases.
Different Types Of Aids For Deaf Children And Adults 
The aids for deaf people either children or an adult are grouped as follow.
Hearing aid
There are further of various types such as:
·         Behind the Ear (BTE)
·         In the Canal (ITC)
·         In the Ear (ITE)
Hearing Protection Devices
Hearing protection devices (HPD) such as earplugs and earmuffs can be a useful measure to keep ears protected in noisy environment (Schwartz, 2007).
Cochlear Implant 
A cochlear implant (CI) is an implanted surgically and is basically an electronic device that can aid in providing a sense of sound to an individual who is intensely deaf.
Aural Rehabilitation
Aural rehabilitation is the practice of recognizing a hearing loss, and then providing diverse sorts of therapies to patients who are Hard of Hearing. It also involves implementation of different amplification devices to help the patients’ hearing skills.
Varieties Of Aural Rehabilitation Therapies
There are numerous such therapies, such as:
·         Listening strategies
·         Unisensory
·         Manual communication
·         Cued speech
·         Auditory Training
·         Hearing aid orientation
·         Speechreading
Assistive Listening Device (ALD) 
These technologies can be classified into three broad categories; namely,
·         Alerting devices
·         Hearing technology
·         Communication supports
Alerting Devices comprises clock, watch fire detection, carbon monoxide detector telephone door bell baby monitor, computer etc.
Communication supports include a range of products such as computer, video, phone, web camera, video relay service, interactive whiteboards, digital pens, caption mic communication access, real time captioning, dragon naturally speaking and many more.
Hearing technology devices are further classified into Assistive Listening Device (such as Induction Loop, FM, 1:1 Communicators and Infrared) and Personal Amplification (including Hearing Aid).
The overall purpose of all of these devices or therapies is enhanced hearing as well as convenience to people regarding their hearing problems.
Types Of Hearing Loss
 There are three major types of hearing loss, such as
1.      Sensorineural hearing loss
2.      Conductive hearing loss
3.      Mixed hearing loss
Sensorineural Hearing Loss
Sensorineural deafness is that type in which hearing loss is the result of problem at the level of nerves supplying the cochlea (Arts, 2010).  This type of hearing makes sounds feel hazy or quieter. It has an effect on all sound frequencies.
Conductive Hearing Loss
Conductive hearing loss is the result of problems within the sound conduction in which sound waves can’t reach to the cochlea (Baloh and Jen, 2011). Here nerve is intact and functioning normally.
Mixed Hearing Loss
Mixed hearing loss involves sensorineural as well as conductive hearing losses (Baloh and Jen, 2011). There may be problem in anywhere within the ear, in outer, inner or middle ear in addition auditory nerve.
The Technological Changes Over The Past Decades As Well As The Potential For Future Development.
The pace of science is usually excruciatingly sluggish. However, over the past few decades a significant stride has been made in healthcare research, treatment of diseases and the betterment of quality of life of patients (Cutler, David, and Ellen, 1999). Though, there are many factors responsible for this growth, but it has been said by the most analysts that the immensity of the long-standing rise resulted from the technological advances used by the health care system.  Major advances in technology have facilitated health care providers to carry out accurate diagnosis and therefore the subsequent treatment. Technological innovation may supposedly have decrease costs and, for numerous varieties of services and goods, often does. A great many advancements in technology has improved lives enormously. 
Technological advances have yielded new, innovative and wanted medical services and will likely to continue yielding in the future. The emerging medical technologies in the health care system has provided huge clinical benefits, for instance improved quality of life in addition to prolonged life. Newer, more diagnostic or therapeutic services are now available with latest technologies, offering highly precise and quick services (Cutler, David and Robert, 2003).
The approach of technological improvement has changed all industries. Technology has been increasingly playing great role in all spheres of life. In healthcare, especially it is doing wonders in almost all processes, starting from registration of patient to monitoring of data, from laboratory tests, reports to self-care instruments. Devices like tablets and smartphones are beginning to replace conservative recording and monitoring systems, and patients are now given the choices of undergoing a full evaluation or consultation in the privacy of their own residences (Technological Change in Health Care (TECH) Research Network., 2001). Technological developments in have contributed to healthcare services being extracted out of the confines of walls of the hospital and incorporating them with comprehensible, reachable devices.
These technological changes hold potential for future for fuelling further growth and a wide variety of choices. Tools are being under consideration as well as interventions are being designed and analysed for even more betterment of the humans and ultimately for improvement of their lives and health.
Medical Model And Analyse Whether Deaf People Are In Agreement With The Philosophy Behind The Medical Model Of Deafness
Deafness in the medical model is regarded as an unwanted condition, requiring treatment. Here people who suffer from hearing loss following acquiring an ability of speaking language. The Medical Model lays emphasis on dependency, a spotlight on the medical cause or condition from which the loss of hearing results. It focuses on vulnerability, passivity, and the deaf individual being a sufferer of their unlucky situation. It concentrates on how deafness is a problem and requires to be amended, no doubt, it is a problem or disability, yet by labelling disability, the sentiments of Deaf people cannot be heard, they have a problem yet they are only different than normal human being but not disable (Reagan, 1995).
But if suppose a person in a meeting or anywhere have to intervene a variety of spoken discussions, how would they do it?  This would become to be a complete nightmare for them. In this situation, they have a disability, particularly if they do not wear hearing aids. Deaf people at times are in harmony with this model because most of the time they are disable, while the cause of their hearing is medical related and therefore require a medical treatment.
However, the medical model may not be the comprehensive one as compared to the social model. The medical model just sees the helplessness of the people while the social model focused on the Deaf individual’s integrity as well as discrimination he/she is experiencing (Holcomb, 1994). In this contest Deaf people cannot be viewed compatible with the philosophy behind the medical model of deafness. Moreover, there are a great number of people who don’t consider themselves handicapped (Hetu, 1996).
In a nut shell, deafness is a social matter rather than just a disease or disability, hence requires eradication of the stigma of deafness as a disability.
