Today we know that what we eat is a major determinant of health, and that food provides both nutritive and healing properties. Functional foods, as defined by the International Food Information Council, are “foods or dietary components that may provide a health benefit beyond basic nutri- tion. Apple skins are a major food source of a type of flavonoid called quercetin, which is a potent antioxidant that helps protect against heart disease and cancer. Anthocyanidins have antioxidant properties, preventing free radical damage and reducing the risk of chronic disease. These compounds are found in other cruciferous vegetables, such as kale, cauliflower, and cabbage. Carotenoids help protect against cardiovascular disease, cancer, macular degeneration, and cataracts, and they also promote good night vision. New research is looking at the effects of another phytonutrient in carrots, called falcarinol, and its ability to reduce the risk of colon cancer. To get the maximum amount of nutrients from carrots, eat them raw or lightly steamed. Oranges, grapefruit, lemons, and limes offer a wide range of nutrients (vitamin C, folate, and fibre). Supplements of lutein have been shown to improve vision in those with macular degeneration and prevent disease progression. One to two serv- ings of kale or collard greens per week provide the recommended amount of lutein and zeaxanthin. Other food sources include spinach, broccoli, and leeks, but they contain a lesser amount. Preliminary research also shows that these compounds may help lower cholesterol, improve gum health, prevent ulcers, and prevent brain damage after a stroke. Health authorities recommend consuming Functional Foods | 35 no more than six meals per year of farmed salmon. To obtain all the benefits, eat the milled flaxseed or get whole seeds and crush them in a food processor or coffee grinder. Store milled seeds in the refrigerator or freezer in an opaque, airtight container; they will be stable for 90 days. Studies have found benefits with as little as 900 mg of garlic per day, which is approximately equivalent to one clove. Clinical studies have validated its benefits for preventing the symptoms of motion sickness (especially seasickness) and in the treatment of nausea and vomiting associated with pregnan- cy. The active compounds in ginger, called gingerols, have potent anti-inflammatory effects, making it helpful in the treatment of arthritis and other inflammatory condi- tions. Choose fresh ginger over the dry (powder) form to maximize intake of the active compounds. This compound has been found to reduce the risk of certain cancers, reduce the size of existing tumours, and inhibit tumour growth. It also sup- ports heart function by lowering blood pressure and reducing the risk of fatal heart attacks. Most studies evaluating the health benefits of green tea in- volved drinking 750–2,500 mL daily. Black tea, white tea, Oolong tea, and other teas derived from the plant Camellia sinesis may offer similar health benefits but are not as widely researched. Studies have found that 3 g of beta-glucan daily can reduce total cholesterol by an average of 5 percent. This 36 | Chapter 3 amount can be found in approximately 60 g of oatmeal or 40 g of oat bran. Powerful sulphur compounds in onions are responsible for their pungent odour and for many of their health benefits. Onions provide a concentrated source of the flavonoid quercitin, which helps reduce inflammation and may halt the growth of cancer. Cooking meats with onions may help reduce the amount of carcinogens produced when meat is cooked at high heat. In general, the more pungent an onion, the more active compounds and health benefits it has. Research suggests that consuming 25 g of soy protein daily can provide a significant cholesterol-lowering effect. Aside from soybeans and tofu, you can get the benefits of soy protein by eating soy nuts, soy milk, soy yogurt, and bars and shakes con- taining soy protein. Lycopene is also present in tomato sauce, tomato paste, and ketchup, which contain a higher amount of lycopene than fresh toma- toes. To obtain 10 mg of lycopene, you would have to eat about 10–15 raw tomatoes, 60 mL (2 oz. Lycopene is also found in papaya, strawberries, watermelon, guava, and pink grapefruit. These active cultures also help digest the naturally occurring sugar (lac- tose) in dairy products that causes bloating and diarrhea in some people. Avoid the “diet” or “light” yogurts, since they are sweetened with aspartame, a chemical whose safety in food is questionable. For this reason those looking for the consistent benefits of probiotics often opt for supplements. Supplements often provide a standardized amount of the active compounds, they are easy to take, and are a great way to complement the diet.

If the bereaved person experiences failures in his or her attempt to adjust in an environment without the lost entity mentat ds syrup 100 ml mastercard, feelings of low self-esteem may result order mentat ds syrup without prescription. Regressed behav- iors and feelings of helplessness and inadequacy are not uncommon buy cheap mentat ds syrup on line. Worden (2009) stated: [Another] area of adjustment may be to one’s sense of the world. Loss through death can challenge one’s fundamental life values and philosophical beliefs—beliefs that are influenced by our fami- lies, peers, education, and religion as well as life experiences. The bereaved person searches for meaning in the loss and its attendant life changes in order to make sense of it and to regain some control of his or her life (pp. Successful achievement of this task determines the outcome of the mourning process—that of continued growth or a state of arrested development. This task allows for the bereaved person to identify a special place for the lost entity. Individuals need not purge from their history or find a replacement for that which has been lost. Instead, there is a kind of continued presence of the lost entity that only becomes relocated in the life of the bereaved. However, there is also the recognition that although the relationship between the bereaved and what has been lost is changed, it is nonetheless still a relationship. Worden (2009) suggests that one never loses memories of a significant relationship. They get stuck at this point in their grieving and later realize that their life in some way stopped at the point the loss occurred (p. Worden (2009) relates the story of a teenaged girl who had a difficult time adjusting to the death of her father. Each stage presents tasks that must be overcome through a painful experiential process. Engel (1964) stated that successful resolution of the grief response is thought to have occurred when a bereaved individual is able “to remem- ber comfortably and realistically both the pleasures and disap- pointments of [what has been lost]. The acute phase of normal grieving usually lasts 6 to 8 weeks—longer in older adults—but complete resolution of the grief response may take much longer. Sadock and Sadock (2007) stated: Ample evidence suggests that the bereavement process does not end within a prescribed interval; certain aspects persist indefinitely for many otherwise high-functioning, normal individuals. Most grief does not fully resolve or permanently disappear; rather grief be- comes circumscribed and submerged only to reemerge in response to certain triggers (p. The grief response can be more difficult if: • The bereaved person was strongly dependent on or per- ceived the lost entity as an important means of physical and/or emotional support. A love-hate relationship may instill feelings of guilt that can interfere with the grief work. Grief tends to be cumulative, and if previous losses have not been resolved, each succeeding grief response becomes more difficult. Grief over loss of a child is often more intense than it is over the loss of an elderly person. The grief response may be facilitated if: • The individual has the support of significant others to assist him or her through the mourning process. The experience of anticipatory grieving is thought to facilitate the grief response that occurs at the time of the actual loss. Loss and Bereavement ● 397 Worden (2009) stated: There is a sense in which mourning can be finished, when people regain an interest in life, feel more hopeful, experience gratification again, and adapt to new roles. Anticipatory Grief Anticipatory grieving is the experiencing of the feelings and emotions associated with the normal grief response before the loss actually occurs. One dissimilar aspect relates to the fact that conventional grief tends to diminish in intensity with the pas- sage of time. Although anticipatory grief is thought to facilitate the actual mourning process following the loss, there may be some problems. In the case of a dying person, difficulties can arise when the family members complete the process of anticipatory grief, and detach- ment from the dying person occurs prematurely. The person who is dying experiences feelings of loneliness and isolation as the psy- chological pain of imminent death is faced without family support. Another example of difficulty associated with premature comple- tion of the grief response is one that can occur on the return of persons long absent and presumed dead (e. In this instance, resumption of the pre- vious relationship may be difficult for the bereaved person. Anticipatory grieving may serve as a defense for some indi- viduals to ease the burden of loss when it actually occurs. It may prove to be less functional for others who, because of interper- sonal, psychological, or sociocultural variables, are unable in advance of the actual loss to express the intense feelings that accompany the grief response. Maladaptive Responses to Loss When, then, is the grieving response considered to be mal- adaptive? These include delayed or inhibited grief, an exaggerated or distorted grief response, and chronic or pro- longed grief. Delayed or Inhibited Grief Delayed or inhibited grief refers to the absence of evidence of grief when it ordinarily would be expected. Many times, cultural influences, such as the expectation to keep a “stiff upper lip,” cause the delayed response. Delayed or inhibited grief is potentially pathological because the person is simply not dealing with the reality of the loss. When this occurs, the grief re- sponse may be triggered, sometimes many years later, when the individual experiences a subsequent loss. Sometimes the grief process is triggered spontaneously or in response to a seemingly insignificant event. The recognition of delayed grief is critical because, depend- ing on the profoundness of the loss, the failure of the mourning process may prevent assimilation of the loss and thereby delay a return to satisfying living. Delayed grieving most commonly occurs because of ambivalent feelings toward the lost entity, outside pressure to resume normal function, or perceived lack of internal and external resources to cope with a profound loss. Distorted (Exaggerated) Grief Response In the distorted grief reaction, all of the symptoms associated with normal grieving are exaggerated. Feelings of sadness, help- lessness, hopelessness, powerlessness, anger, and guilt, as well as numerous somatic complaints, render the individual dysfunc- tional in terms of management of daily living. Murray, Zentner, and Yakimo (2009) described an exaggerated grief reaction in the following way: An intensification of grief to the point that the person is over- whelmed, demonstrates prolonged maladaptive behavior, manifests excessive symptoms and extensive interruptions in healing, and does not progress to integration of the loss, finding meaning in the loss, and resolution of the mourning process (p. When the exaggerated reaction occurs, the individual remains fixed in the anger stage of the grief response. This anger may be directed toward others in the environment to whom the in- dividual may be attributing the loss.

Usage subject to terms and conditions of license 94 2 Basic Principles of Immunology Table 2. Immunological Memory Immunological memory is usually defined by an earlier and better immune response, mediated by increased frequencies of specific B or T cells as deter- mined by in vitro or adoptive transfer experiments. B-cell immunological memory is more completely described as the ability to mediate protective immunity by means of increased antibody concentrations. Higher frequen- cies of specific B and T lymphocytes alone, appears to only provide limited Kayser, Medical Microbiology © 2005 Thieme All rights reserved. Usage subject to terms and conditions of license Immunological Memory 95 or no protection. Instead, immunological protection requires antigen-depen- dent activation of B and Tcells, which thenproduce antibodies continuously or can rapidly mediate effector T functions and can rapidly migrate into per- ipheral tissues to control virus infections. Usually the second time a host encounters the same antigen its immune 2 response is both accelerated and augmented. This secondary immune re- sponse is certainly different from the primary response, however, it is still a matter of debate as to whether these parameters alone correlate with im- mune protection. It is not yet clear whether the difference between a primary and secondary immune response results solely from the increased numbers of antigen-specific B and T cells and their acquisition of “memory qualities”, or whether immune protection is simply due to continuous antigen-induced activation (Table 2. Usage subject to terms and conditions of license 96 2 Basic Principles of Immunology There is no surface marker which can unequivocally differentiate between memory T and B cells and “naive” (never before activated) cells. Instead, im- munological memory is normally taken to correlate with an increased num- ber of specific precursor Tand B cells. Following an initial immunization with antigen, this increased precursor frequency of specific cells is thought to be 2 maintained by an antigen-independent process. Yet the precursor cells can only be activated (or re-activated) by antigen, and only activated T cells can provide immediate protection against re-infection outside the lymphoid or- gans, e. Similarly, only antigen activated B cells can mature to become plasma cells which maintain the increased blood antibody titers responsible for mediating protection. This indicates that re- sidual antigen must be present to maintain protective immunological mem- ory. As a general rule, the level of protective immunity mediated by the ex- istence of memory T and B cells per se is minimal. Highly effective immunity and resistance to re-infection are instead provided by migratory Tcells which have been recently activated (or re-activated) by antigen, and by antibody- secreting B cells. B-cell and antibody memory is maintained by re-encoun- ters with antigen, or by antigen-IgG complexes which by virtue of their Fc portions or by binding to C3b are captured by-, and maintained for long periods on-, follicular dendritic cells present in germinal centers. Mem- ory T cells, and in some cases B cells, can be re-stimulated and maintained in an active state by: persistent infections (e. Thus, secondarily activated (protective) memory T and B cells can- not easily be distinguished from primarily activated T and B cells. The anti- gen-dependent nature of immunological protection indeed questions the relevance of a specialized “memory quality” of B and T cells. B-Cell Memory It is important to differentiate between the characteristics of memory T and B cells as detected in vitro, and the salient in-vivo attributes of improved immune defenses. Following a primary immune response, increased num- bers of memory B cells can of course be detected using in vitro assays or by murine experiments involving the transfer of cells into naive recipients. However, these increased B cell frequencies do not necessarily ensure im- mune protection against, for instance, viral re-infection. Such protection requires the existence of an increased titer of protective antibodies within the host. Usage subject to terms and conditions of license Immunological Memory 97 Why is Immunological Memory Necessary? A host which does not survive an initial infection obviously does not require further immunological memory. On the other hand, survival of the initial infection proves that the host’s immune system can control or defeat the infection, once again ap- parently negating the need for immunological memory. Even assuming that better 2 immune defenses provide a clear evolutionary advantage, especially during preg- nancy, the idea of immunological memory must be understood as protection within a developmental framework: 1. For the same reason, a child’s T cells apparently cannot mature until relatively late in its development (usually around the time of birth). This explains why newborns are almost entirely lacking in active immune defenses (Fig. Newborn mice require about three to four weeks (humans three to nine months) before the T-cell immune response and the process of T-B cell collaboration which results in the generation of antibody re- sponses become fully functional. This type of protection is mediated by the transfer of protective, largely IgG, antibodies from mother to child through the placenta during pregnancy, and to some extent within the mother’s milk. An example of this is provided by cattle where the acquisition of colostral milk by the calf is essential to its survival. Calves can only access protective IgG through the colostral milk delivered during the first 24 hours after birth (fetal calf serum contains no Ig). During the first 18 hours post partum, the calf’s intestine expresses Fc receptors which allow the uptake of undigested antibodies from the mothers milk into the bloodstream. How can com- prehensive, transferable, antibody-mediated protection be ensured under these conditions? During a three-week murine or 270-day human pregnancy, mothers do not normally undergo all of the major types of infection (indeed infection can be potentially life-threatening for both the embryo/fetus and the mother), and so the array of antibodies required for comprehensive protection cannot be accumulated during this period alone. Instead, an accumulation of the immuno- logical protective antibody levels representing the immunological life experience of infections in the mother’s serum is necessary. The female sex hormones also encourage Ig synthesis, correlating with women’s higher risk level (about fivefold) for developing autoantibody diseases (e. Reproduction requires a relatively good level of health and a good nutritional status of the mother. However, it also requires an effective immune defense status within the population (herd), including males, since all would otherwise be threatened by repeated and severe infections. The increased frequency of specific precursor B and T cells improves immune defenses against such infections. How- ever, this relative protection is in clear contrast to the absolute protection an immunoincompetent newborn requires to survive.

The ingredient in a drug that causes a physiological response is called (a) D-fill discount mentat ds syrup 100 ml line. The method in which a drug is absorbed by flowing from a high concen- tration to a low concentration is called: (a) active diffusion quality 100 ml mentat ds syrup. Primary loading is the first measured quantity of drug that is eliminated from the body discount mentat ds syrup 100 ml with mastercard. A drug that causes a nonspecific physiological response is called a(n) (a) agonist. The voice simply becomes more insistent until you have no choice but to open your eyes. This is to determine if the medication is having an effect or if the patient is experi- encing an undesirable side effect. In cases where the patient is being treated with a narrow spectrum antibiotic, blood may be drawn to determine if the antibiotic is working on the infection. Administering medication, evaluating the patient’s response, and determining if the drug is working as planned are pharmacology activities that are part of the nursing process. This chapter takes a look at the nursing process as it relates to giving medications. During the assessment step, the nurse is gather- ing subjective and objective data from the patient that will later be used to arrive at a nursing diagnosis. Subjective data is information that is reported by the patient such as, “I’m feeling warm. Diagnosis is the patient’s problem, which is determined by analyzing data collected during the patient’s assessment. The data could lead the nurse to deter- mine that the patient has more than one problem. For example, a nurse might diagnose an alteration in mobility in a patient who has had a stroke. The nurse might also determine this patient has a potential for alteration in nutrition because he or she is having difficulty swallowing because of the stroke. The plan takes the form of a care plan that itemizes the patient’s nursing diagnosis. The care plan contains at least one nursing intervention for each nursing diagnosis, the expected out- come for each intervention, and how the nurse will evaluate the outcome. For example, the final outcome goal for an alteration in mobility might be to have the patient get out of bed and ambulate without assistance. However, the inter- ventions will begin with getting the patient out of bed and to the chair or assist- ing the patient to walk short distances each day. For example, the nurse will assist the patient to the chair the first time and might delegate the task to a nursing assis- tant thereafter if the patient does not have any problems. If the patient continues to have no problems getting out of bed, the nurse may change the interventions to include walking short distances in addition to getting out of bed and increase those distances each day. When the patient is able to get out of bed and walk without assistance, the final goal will have been achieved. If the nurse determines during the evaluation step that the intervention didn’t work or the expected outcome has been achieved, the nurse begins the nursing process again, starting with the assessment step and then revises the care plan as the patient’s problem changes. A portion of the assessment process directly relates to administering medication to the patient. Before medication is given to a patient, the nurse must make the follow assessments. A drug order must be written by a physician, dentist, physician assistant, or advanced practice nurse and contain: • The date and time the order is written • The name of the drug • The dosage • The route of administration • The frequency of administration • The duration (how long the patient is to receive the drug) • The signature of the prescriber Identify the brand and generic name for the drug Drugs are known under several names. The nurse is required to know why the drug is given to the patient and what symptoms a patient exhibits to indicate that the drug should be administered. The nurse cannot rely solely on the prescriber because the patient’s condition might have changed since the patient was assessed. These include, but are not limited to, writing an order or a prescrip- tion for the wrong patient, for a drug to which the patient is allergic, for a drug that will interact badly with another drug the patient is taking, a dose that is too small or too large for the patient based on weight, or simply the wrong drug. Medication errors can be reduced or eliminated if everyone involved in the process uses critical thinking skills and checks and double checks the orders, the patient, and the medication. It is critical that the nurse understands how the drug is absorbed, distributed, metabolized, and eliminated before administering the drug to the patient. For example, the patient might have lower than expected urinary output and is unable to excrete the drug in normal volume resulting in a potential toxic buildup in the body. The nurse must also know the drug’s onset of action, peak action, and dura- tion of action. As you’ll recall from the previous chapter, onset is the time period when the drug reaches the minimally effective concentration in the plasma. The effectiveness of a drug can be influenced by interactions with food, herbal remedies, and other drugs that alter or modify the drug’s action. Such interac- tions might increase the drug’s effectiveness, decrease it, or neutralize it. A side effect is a physiological response in the patient’s body that is not re- lated to the drug’s primary action. Some side effects are beneficial while side effects—such as nausea and vomiting—are undesirable. By knowing a drug’s possible side effects, the nurse can prepare to manage them before the patient is given the drug. A drug’s toxicity is the drug concentration in plasma and accumulation in tissues that exceeds the drug’s therapeutic range. The nurse must note the signs and symptoms that indicate the patient is having an adverse reaction to a drug or that the drug has reached toxic levels. These indications may not be present for minutes, hours, and even days after the drug is administered. Many drugs are self-administered by patients after they leave the healthcare facility. Therefore it is important that the nurse identify information about the drug that the patient needs to know to properly administer the drug. The nurse must make sure the drug is available and make sure that the drug on hand hasn’t expired if it is available. For example, some healthcare facilities might have a very low requirement for a particular drug and the stock of the drug might be old and have passed the expiration date. Some drugs are not covered by the patient’s health insurance because they are expensive. In addition, many patients do not have insurance to cover medications and they can- not afford to have an expensive prescription filled. Nurses should ask patient’s about their insurance coverage and if they can afford to buy the medication if they don’t have coverage. Many patients might stop taking an important medication because they don’t have enough money. The nurse must determine: • Does the patient have any allergies to the drug or to food that might be given along with the drug?
