Often small infection vs inflammation cheap zyvox 600 mg amex, frequent meals are tolerated better than three large meals because of the abdominal pressure exerted by ascites virus 2 game buy zyvox 600 mg amex. Patients with prolonged or severe anorexia antibiotics jeopardy discount 600mg zyvox mastercard, or those who are vomiting or eating poorly for any reason infection in blood zyvox 600 mg on-line, may receive nutrients enterally or parenteral nutrition. Patients with fatty stools (steatorrhea) should receive watersoluble forms of fat-soluble vitamins-A, D, and E (Aquasol A, D, and E). If the patient shows signs of impending or advancing coma, the amount of protein in the diet is decreased temporarily. In the absence of hepatic encephalopathy, a moderate-protein, high-calorie intake is provided, with protein foods of high biologic value. Protein is restricted Chapter 39 Assessment and Management of Patients With Hepatic Disorders 1105 cumulation of ammonia in the blood and its effect on cerebral metabolism. Many factors predispose the patient with cirrhosis to hepatic encephalopathy; therefore, the patient may require extensive diagnostic testing to identify hidden sources of bleeding and ammonia. Treatment may include the use of lactulose and nonabsorbable intestinal tract antibiotics to decrease ammonia levels, modification in medications to eliminate those that may precipitate or worsen hepatic encephalopathy, and bed rest to minimize energy expenditure. Monitoring is an essential nursing function to identify early deterioration in mental status. Because electrolyte disturbances can contribute to encephalopathy, serum electrolyte levels are carefully monitored and corrected if abnormal. The nurse monitors for fever or abdominal pain, which may signal the onset of bacterial peritonitis or other infection (see the discussion of hepatic encephalopathy in the "Hepatic Dysfunction" section of this Chapter). Fluid Volume Excess Patients with advanced chronic liver disease develop cardiovascular abnormalities. These occur due to an increased cardiac output and decreased peripheral vascular resistance, possibly resulting from the release of vasodilators. A hyperdynamic circulatory state develops in patients with cirrhosis, and plasma volume increases. This increase in circulating plasma volume may be due in part to splanchnic venous congestion (Bircher et al. The greater the degree of hepatic decompensation, the more severe the hyperdynamic state. Close assessment of the cardiovascular and respiratory status is key for the nurse caring for patients with this disorder. Pulmonary compromise is always a potential complication of endstage liver disease due to plasma volume excess, making prevention of pulmonary complications an important role for the nurse. Administering diuretics, implementing fluid restrictions, and enhancing patient positioning can optimize pulmonary function. Fluid retention may be noted in the development of ascites and lower extremity swelling and dyspnea. Monitoring intake and output, daily weight changes, changes in abdominal girth, and edema formation is part of nursing assessment in the hospital or in the home setting. Patients are also monitored for nocturia and, later, oliguria as these states indicate increasing severity of liver function (Bacon & Di Bisceglie, 2000). The patient may need referral to Alcoholics Anonymous, psychiatric care, or counseling or may benefit from support from a spiritual advisor. The patient will require written instructions, teaching, reinforcement, and support from the staff as well as the family members. The success of treatment depends on convincing the patient of the need to adhere completely to the therapeutic plan. This includes rest, lifestyle changes, adequate dietary intake, and the elimination of alcohol. The nurse also instructs the patient and family about the symptoms of impending encephalopathy, possible bleeding tendencies, and susceptibility to infection. Recovery is neither rapid nor easy; there are frequent setbacks and apparent lack of improvement. Many patients find it difficult to refrain from using alcohol for comfort or escape. The nurse has a significant role in offering support and encouragement to this patient. Continuing Care Referral of the patient for home care may assist the patient in dealing with the transition from hospital to home, where the use of alcohol may have been an important part of normal home and social life. The nurse also reinforces previous teaching and answers questions that may not have occurred to the patient or family until the patient is back home and trying to establish new patterns of eating, drinking, and lifestyle.

Severe symptoms have been labeled as premenstrual dysphoric disorder (DiCarlo, Palomba, Tommaselli et al. Some clinicians prescribe analgesic agents, diuretic medications, and natural and synthetic progesterones, although the long-term risks of progesterone use are unknown. Many women find over-the-counter carbohydrate products useful; they provide complex carbohydrates along with vitamins and minerals. Ratios of serum levels of tryptophan to other amino acids are elevated in patients who use tryptophan. Calcium (1,200 mg/day) has been found to be effective, as has magnesium (200 to 400 mg/day). General irritability, mood swings, fear of losing control, binge eating, and crying spells may also occur. Symptoms vary widely from one woman to another and from one cycle to the next in the same person. Many women are not bothered at all, whereas some experience severe and disabling symptoms (Morse, 1999). A generally stressful life and problematic relationships may be related to the intensity of physical symptoms. Identifying the time when these symptoms occur helps in determining the diagnosis. Symptoms recur regularly at the same phase of each menstrual cycle, usually 1 week to a few days before menses, and subside once the menstrual flow starts. Nursing Management the nurse should establish rapport with the patient and obtain a health history, noting the time when symptoms began and their nature and intensity. The nurse then determines whether the onset of symptoms occurs before or shortly after the menstrual flow begins. Additionally, the nurse can show the patient how to develop a chart to record the timing and intensity of symptoms. A nutritional history is also elicited to determine if the diet is high in salt, caffeine, or alcohol or low in essential nutrients. Partners can be advised to assist by offering support and increased involvement with childcare. The nurse encourages the patient to use exercise, meditation, imagery, and creative activities to reduce stress. Exercise is encouraged for all patients as noncontrolled studies have shown a benefit. Many practitioners advise women to avoid caffeine, high-fat foods, and refined sugars, but there is little research to demonstrate the efficacy of dietary changes. Alternative therapies that women have used include vitamins B and E, magnesium, and oil of evening Chapter 46 Assessment and Management of Female Physiologic Processes 1391 vides instructions about the desired effects of the medications. Any suggestions of suicidal tendencies must be evaluated by psychiatric consultation immediately. It is characterized by crampy pain that begins before or shortly after the onset of menstrual flow and continues for 48 to 72 hours. Dysmenorrhea is thought to result from excessive production of prostaglandins, which causes painful contraction of the uterus and arteriolar vasospasm. Psychological factors, such as anxiety and tension, may also contribute to dysmenorrhea. As women grow older, dysmenorrhea often decreases and frequently completely resolves after childbirth. Patients with secondary dysmenorrhea frequently have pain that occurs several days before menses, with ovulation, and occasionally with intercourse. Continuous low-level local heat has recently been found to be effective in treating primary dysmenorrhea and may be as effective as medication (Akin, Weingand, Hengehold et al. The mechanism is not clear, but heat may counteract the activity of hormones that cause the uterus to contract.

The postpuncture headache is usually managed by bed rest antibiotic resistance questions and answers zyvox 600mg amex, analgesic agents antibiotics for uti sulfamethoxazole buy discount zyvox 600mg line, and hydration (Connolly virus informaticos order zyvox mastercard, 1999) antimicrobial bandages buy zyvox 600mg overnight delivery. Occasionally, if the headache persists, the epidural blood patch technique may be used. Blood is withdrawn from the antecubital vein and injected into the epidural space, usually at the site of the previous spinal puncture. The needle is usually inserted into the subarachnoid space between the third and fourth or fourth and fifth lumbar vertebrae. Because the spinal cord divides into a sheaf of nerves at the first lumbar vertebra, insertion of the needle below the level of the third lumbar vertebra prevents puncture of the spinal cord. A successful lumbar puncture requires that the patient be relaxed; an anxious patient is tense, and this may increase the pressure reading. The increase in pressure caused by the compression is noted; then the pressure is released and pressure readings are made at 10-second intervals. A slow rise and fall in pressure indicates a partial block due to a lesion compressing the spinal subarachnoid pathways. Other Complications of Lumbar Puncture Herniation of the intracranial contents, spinal epidural abscess, spinal epidural hematoma, and meningitis are rare but serious complications of lumbar puncture. Other complications include temporary voiding problems, slight elevation of temperature, backache or spasms, and stiffness of the neck. Therefore, the patient and family must receive clear verbal and written instructions about precautions to take after the procedure, complications to watch for, and steps to take if complications occur. Because many patients undergoing neurologic diagnostic studies are elderly or have neurologic deficits, provisions must be made to ensure that transportation and postprocedure care and monitoring are available. Usually, specimens are obtained for cell count, culture, and glucose and protein testing. The specimens should be sent to the laboratory immediately because changes will take place and alter Chapter 60 Assessment of Neurologic Function 1847 Chart 60-4 Guidelines for Assisting with a Lumbar Puncture A needle is inserted into the subarachnoid space through the third and fourth or fourth and fifth lumbar interface to withdraw spinal fluid. Explain the procedure to the patient and describe sensations that are likely during the procedure (ie, a sensation of cold as the site is cleansed with solution, a needle prick when local anesthetic is injected). Determine whether the patient has any questions or misconceptions about the procedure; reassure the patient that the needle will not enter the spinal cord or cause paralysis. The patient is positioned on one side at the edge of the bed or examining table with back toward the physician; the thighs and legs are flexed as much as possible to increase the space between the spinous processes of the vertebrae, for easier entry into the subarachnoid space. The physician cleanses the puncture site with an antiseptic solution and drapes the site. Local anesthetic is injected to numb the puncture site, and then a spinal needle is inserted into the subarachnoid space through the third and fourth or fourth and fifth lumbar interspace. The nurse assists the patient to maintain the position to avoid sudden movement, which can produce a traumatic (bloody) tap. The patient is encouraged to relax and is instructed to breathe normally, because hyperventilation may lower an elevated pressure. Monitor the patient for complications of lumbar puncture; notify physician if complications occur. Continuing Care Contacting the patient and family after diagnostic testing enables the nurse to determine whether they have any questions about the procedure or whether the patient had any untoward results. During these phone calls, teaching is reinforced and the patient and family are reminded to make and keep follow-up appointments. Patients, family members, and health care providers are focused on the immediate needs, issues, or deficits that necessitated the diagnostic testing. This is also a good time to remind them of the need for and importance of continuing health promotion and screening practices and make referrals to appropriate health care providers. What nursing observations and assessments are indicated because of the occurrence of these two disorders? Describe the procedure, its duration, and preparation for this test, including medication/diet restrictions, if any. What explanation can you give to the patient and his wife regarding the difference between the two procedures? What additional information will help prepare the patient to undergo this procedure? Neurotransmitters of the brain: Serotonin noradrenaline, norepinephrine, and dopamine.

Therefore bacteria helicobacter pylori sintomas order zyvox cheap online, fewer receptors are available for stimulation antibiotics for sinus infection and drinking generic zyvox 600 mg with mastercard, resulting in voluntary muscle weakness that escalates with continued activity virus hoaxes 600 mg zyvox with visa. Eighty percent of persons with myasthenia gravis have either thymic hyperplasia or a thymic tumor (Roos antibiotic home remedies buy discount zyvox line, 1999), and the thymus gland is believed to be the site of antibody production. In patients who are antibody negative, it is believed that the offending antibody is directed at a portion of the receptor site rather than the whole complex. Clinical Manifestations the initial manifestation of myasthenia gravis usually involves the ocular muscles. However, the majority of patients also experience weakness of the muscles of the face and throat (bulbar symptoms) and generalized weakness. Generalized weakness affects all the extremities and the intercostal muscles, resulting in decreasing vital capacity and respiratory failure. Myasthenia gravis is purely a motor disorder with no effect on sensation or coordination. Women tend to develop the disease at an earlier age (20 to 40 years of age) compared to men (60 to 70 years of age), and women are affected more frequently (Heitmiller, 1999). Assessment and Diagnostic Findings An anticholinesterase test is used to diagnose myasthenia gravis. Anticholinesterase agents stop the breakdown of acetylcholine, thereby increasing acetylcholine availability. Edrophonium chloride (Tensilon) is injected intravenously, 2 mg at a time to a total of 10 mg. Thirty seconds after injection, facial muscle weakness and ptosis should resolve for about 5 minutes. This immediate improvement in muscle strength after administration of this agent represents a positive test and usually confirms the diagnosis. Repetitive nerve stimulation tests record the electrical activity in targeted muscles after nerve stimulation. A 15% decrease in successive action potentials is observed in patients with myasthenia gravis (Heitmiller, 1999). The thymus gland, which is a site of acetylcholine receptor antibody production, is enlarged in myasthenia gravis. Pathophysiology Normally, a chemical impulse precipitates the release of acetylcholine from vesicles on the nerve terminal at the myoneural junction. The acetylcholine attaches to receptor sites on the motor end plate, stimulating muscle contraction. Continuous binding of acetylcholine to the receptor site is required for muscular contraction to be sustained. Chapter 64 Medical Management Management of Patients With Neurologic Infections, Autoimmune Disorders, and Neuropathies 1957 Management of myasthenia gravis is directed at improving function and reducing and removing circulating antibodies. Therapeutic modalities include administration of anticholinesterase agents and immunosuppressive therapy, plasmapheresis, and thymectomy. Dosage is increased gradually until maximal benefits (improved strength, less fatigue) are obtained. Adverse effects of anticholinesterase therapy include abdominal pain, diarrhea, nausea, and increased oropharyngeal secretions. Improvement with anticholinesterase therapy is not complete or long-lasting (Heitmiller, 1999). Any delay in administration of medications may exacerbate muscle weakness and make it impossible for the patient to take medications orally. Cytotoxic medications have also been used, although the precise mechanism of action in myasthenia is not fully understood. Medications such as azathioprine (Imuran), cyclophosphamide (Cytoxan), and cyclosporine reduce the circulating antiacetylcholine receptor antibody titers. Side effects are significant; therefore, these agents are reserved for patients who do not respond to other forms of therapy. A number of medications are contraindicated for patients with myasthenia gravis because they worsen myasthenic symptoms. Risks and benefits should be weighed by the physician and the patient before taking any new medications, including antibiotics, cardiovascular medications, antiseizure and psychotropic medications, morphine, quinine and related agents, beta-blockers, and nonprescription medications. The blood cells and antibody-containing plasma are separated; then the cells and a plasma substitute are reinfused. Plasma exchange produces a temporary reduction in the titer of circulating antibodies.
