The deﬁning characteristics describe what the client says and what the nurse observes that indicate the existence of a particular problem discount 2mg estradiol free shipping. This book may be used as a guide in the construction of care plans for various psychiatric clients buy estradiol 2mg amex. The use of this format is not to imply that nursing diagnoses are based on quality estradiol 1 mg, or ﬂow from, medical diagnoses; it is meant only to enhance the usability of the book. In addition, I am not suggest- ing that those nursing diagnoses presented with each psychiatric category are all-inclusive. It is valid, however, to state that certain nursing diagnoses are indeed common to individuals with speciﬁc psychiatric dis- orders. The diagnoses presented in this book are intended to be used as guidelines for construction of care plans that must be individualized for each client, based on the nursing assessment. The interventions can also be used in areas in which interdisci- plinary treatment plans take the place of the nursing care plan. The Disorder: A deﬁnition and common types or categories that have been identiﬁed. Predisposing Factors: Information regarding theories of etiology, which the nurse may use in formulating the “re- lated to” portion of the nursing diagnosis, as it applies to the client. Symptomatology: Subjective and objective data identifying behaviors common to the disorder. These behaviors, as they apply to the individual client, may be pertinent to the “evi- denced by” portion of the nursing diagnosis. Possible Etiologies (“related to”): This section suggests possible causes for the problem identiﬁed. Note: Deﬁning characteristics are replaced by “related/risk factors” for the “Risk for” diagnoses. Deﬁning Characteristics (“evidenced by”): This section in- cludes signs and symptoms that may be evident to indicate that the problem exists. Goals/Objectives: These statements are made in client behav- ioral objective terminology. They are measurable, short- and long-term goals, to be used in evaluating the effectiveness of the nursing interventions in alleviating the identiﬁed problem. There may be more than one short-term goal, and they may be considered “stepping stones” to fulﬁllment of the long-term goal. For purposes of this book, “long-term,” in most instances, is designated as “by discharge from treatment,” whether the client is in an inpatient or outpatient setting. Interventions with Selected Rationales: Only those inter- ventions that are appropriate to a particular nursing diagno- sis within the context of the psychiatric setting are presented. Rationales for selected interventions are included to provide clariﬁcation beyond fundamental nursing knowledge, and to assist in the selection of appropriate interventions for indi- vidual clients. Important interventions related to communi- cation may be identiﬁed with the icon. Outcome Criteria: These are behavioral changes that can be used as criteria to determine the extent to which the nurs- ing diagnosis has been resolved. To use this book in the preparation of psychiatric nursing care plans, ﬁnd the section in the text applicable to the client’s psychiatric diagnosis. Select nursing interventions and outcome criteria appropriate to the client for each nursing diagnosis identiﬁed. Include all of this information on the care plan, along with a date for evaluating the status of each problem. On the evaluation date, document success of the nursing inter- ventions in achieving the goals of care, using the desired client outcomes as criteria. Topics related to forensic nursing, psychiatric home nurs- ing care, and complementary therapies are also included. This information should facilitate use of the book for nurses adminis- tering psychotropic medications and also for nurse practitioners with prescriptive authority. Information is pre- sented related to indications, actions, contraindications and pre- cautions, interactions, route and dosage, and adverse reactions and side effects. Examples of medications in each chemical class are presented by generic and trade name, along with information about half-life, controlled and pregnancy categories, and avail- able forms of the medication. Nursing diagnoses related to each category, along with nursing interventions, and client and family education are included in each chapter. Another helpful feature of this text is the table in Appendix N, which lists some client behaviors commonly observed in the psychiatric setting and the most appropriate nursing diagnosis for each. It is hoped that this information will broaden the un- derstanding of the need to use a variety of nursing diagnoses in preparing the client treatment plan.
For example: • Children who are picky eaters could be lacking in various nutrients estradiol 2 mg free shipping, such as vitamin C and iron order estradiol 2mg with visa. Vitamin B12 and other B vitamins may be deﬁcient in older individuals depending on diet purchase estradiol 1 mg amex, medical conditions, and prescription drug use. Chapter 2 provides extensive information on vitamins and minerals, including dos- age ranges based on age and gender, as well as nutrients that may be depleted by prescription drugs or certain health conditions. Principles of Safe Supplementing | 69 Green Foods Most people ﬁnd it difﬁcult to consume the recommended seven to 10 servings of fruits and vegetables per day that provide our primary dietary source of vitamins and minerals. To complement your diet, you may want to consider taking a green foods supplement. Green foods such as chlorella, spirulina, barley grass, and wheat grass provide vital nutrients such as antioxidants, minerals, and ﬁbre, which can help boost energy levels, support detoxiﬁcation, and enhance well-being. You can add your greens+ to your morning pro- tein shake, or mix with juice or water. They are required for growth and development of the brain, nervous system, adrenal glands, sex organs, and eyes. They maintain the health of cell membranes, produce hormones and brain chemicals, and regulate various cell processes. Omega-3s are present in ﬁsh and, to a lesser extent, in some plants (ﬂaxseed and leafy green vegetables). Omega-3 deﬁciency is thought to be quite common, and supplementing with omega-3s offers a number of health beneﬁts, such as reducing the risk of heart attack, and improving brain function and skin health. Omega-3 supplements are also recommended for women who are trying to get preg- nant or who are pregnant as these good fats are essential to the growing brain, eyes, and nervous system of the baby. Look for a pharmaceutical- grade, cold-pressed ﬁsh oil from a reputable manufacturer. For example, if you have osteoporosis, you may require extra minerals, vitamin D, and other nutrients. If you have heart disease, it would be wise to take coenzyme Q10 along with extra antioxidants. In Section 3 I provide concise guidelines on supplement recommendations for various health conditions. Keep in mind that it is always wise to consult with a professional for advice on which supple- ments to take, the appropriate dosage, and any precautions. Do’s • Research your options—consult with your pharmacist or health care provider and ﬁnd out as much as you can about the products you are considering. In particular ask if there are any possible interactions with medications or side effects. This will keep the amount of pills you take to a minimum and will also be easier on your budget. Depending on your diet and needs, you may still need to take additional vitamin C, E, and cal- cium as it is difﬁcult to ﬁt all of these nutrients into one tablet. Don’ts • Don’t take supplements with sugar, starch, corn, wheat, iron, dairy, salt, artiﬁcial ﬂavourings and colourings (dyes), and preservatives. These are unnecessary ingre- dients that can cause allergic reactions in some people. Some vitamins are more expensive due to company marketing and advertising costs and are not necessarily made with bet- ter ingredients. After that, ask yourself what’s missing from your diet and what concerns you the most about your health. Focus on one concern at a time, exploring different nutritional supplements that may offer help. If you invest the time into creat- ing a supplement program that’s right for your individual needs, your reward should be improved quality of life. In the last 20 years, there has been a strong resurgence of homeopathy, which has become the fastest-growing ﬁeld of integrative medicine in Canada, and is the second most popular form of any medicine worldwide. Even though the nature of homeopathy, its scope, and its applications in health care are less understood in Canada, it remains clear that more than ever, Canadians are turning to homeopathy as an addition to their preventative routines as well as a solution to their most common health complaints. Homeopathy is part of a trillion- dollar, North American natural health care industry. Homeopathic medicine is second in popularity only to mainstream or conventional medicine. Because homeopathy is an inexpensive alternative with little proﬁt margin and no possibility for patenting, its marketability to mainstream practitioners is low, so few are aware of its beneﬁts in a clinical setting. Contemporary Canadian society’s newfound understanding of health care as preven- tion of disease has led to a new perspective of natural approaches like homeopathy as mainstream. In line with this new deﬁnition of health care, homeopathy helps the body to do what it should be able to do on its own to keep the body healthy and free of disease. Conventional approaches, such as drugs and surgery, are sometimes necessary, but these approaches should soon become known as the complementary approach! For over 200 years, Canadians have been using homeopathic medicines suc- cessfully to treat acute and chronic illnesses. Interestingly, homeopaths were recognized under government structure before practitioners of conventional med- icine.
However discount estradiol 2 mg on line, this variability can also be understood by examining the other factors involved in the clinical decision-making process buy estradiol 2mg without a prescription. Explaining variability – clinical decision making as problem solving A model of problem solving Clinical decision-making processes are a specialized form of problem solving and have been studied within the context of problem solving and theories of information pro- cessing buy generic estradiol canada. It is often assumed that clinical decisions are made by the process of inductive reasoning, which involves collecting evidence and data and using this data to develop a conclusion and a hypothesis. For example, within this framework, a general practitioner would start a consultation with a patient without any prior model of their problem. However, doctors’ decision-making processes are generally considered within the framework of the hypothetico-deductive model of decision making. This perspective emphasizes the development of hypotheses early on in the consultation and is illustrated by Newell and Simon’s (1972) model of problem solving, which emphasizes hypothesis testing. Newell and Simon suggested that problem solving involves a number of stages that result in a solution to any given problem. This model has been applied to many diﬀerent forms of problem solving and is a useful framework for examining clinical decisions (see Figure 4. The stages involved are as follows: 1 Understand the nature of the problem and develop an internal representation. At this stage, the individual needs to formulate an internal representation of the problem. This process involves understanding the goal of the problem, evaluating any given conditions and assessing the nature of the available data. Newell and Simon diﬀerentiated between two types of plans: heuristics and algorithms. An algorithm is a set of rules that will provide a correct solution if applied correctly (e. However, most human problem solving involves heuristics, which are rules of thumb. Heuristics may involve developing parallels between the present problem and previous similar ones. The individual then decides whether the heuristics have been successful in the attempt to solve the given problem. If they are considered unsuccessful, the individual may need to develop a new approach to the problem. The end-point of the problem-solving process involves the individual deciding that an acceptable solution to the problem has been reached and that this solution provides a suitable outcome. According to Newell and Simon’s model of problem solving, hypotheses about the causes and solutions to the problem are developed very early on in the process. They regarded this process as dynamic and ever-changing and suggested that at each stage of the process the individual applies a ‘means end analysis’, whereby they assess the value of the hypothesis, which is either accepted or rejected according to the evidence. This type of model involves information processing whereby the individual develops hypotheses to convert an open problem, which may be unmanageable with no obvious end-point, to one which can be closed and tested by a series of hypotheses. Models of problem solving have been applied to clinical decision making by several authors (e. MacWhinney 1973; Weinman 1987), who have argued that the process of formulating a clinical decision involves the following stages (see Figure 4. The initial questions in any consultation from health professional to the patient will enable the health professional to understand the nature of the problem and to form an internal repre- sentation of the type of problem. Early on in the problem-solving process, the health professional develops hypotheses about the possible causes and solutions to the problem. The health professional then proceeds to test the hypotheses by searching for factors either to conﬁrm or to refute their hypotheses. Research into the hypothesis testing process has indicated that although doctors aim to either conﬁrm or refute their hypothesis by asking balanced questions, most of their questioning is biased towards conﬁrmation of their original hypothesis. Therefore, an initial hypothesis that a patient has a psychological problem may cause the doctor to focus on the patient’s psychological state and ignore the patient’s attempt to talk about their physical symptoms. Furthermore, the type of hypothesis has been shown to bias the collection and interpretation of any information received during the consultation (Wason 1974). The outcome of the clinical decision-making process involves the health professional deciding on the way forward. Weinman (1987) suggested that it is important to realize that the outcome of a consultation and a diagnosis is not an absolute entity, but is itself a hypothesis and an informed guess that will be either conﬁrmed or refuted by future events. Explaining variability Variability in the behaviour of health professionals can therefore be understood in terms of the processes involved in clinical decisions. For example, health professionals may: s access diﬀerent information about the patient’s symptoms; s develop diﬀerent hypotheses; s access diﬀerent attributes either to conﬁrm or to refute their hypotheses; s have diﬀering degrees of a bias towards conﬁrmation; s consequently reach diﬀerent management decisions.
