good essay writing example 1,45 iv corticosteroids should be used only if the oral route is not tolerated because there is no clinical benefit over oral therapy. 1,44 nebulized budesonide may be used as an alternative but is more expensive and is not recommended over oral or iv corticosteroids during an exacerbation. 1 antibiotics  routine use of antibiotics is controversial due to the possibility of nonbacterial causes of copd exacerbations. 1,46 approximately 50% of exacerbations are caused by bacterial infections, and there may be benefit to treating most, if not all, copd exacerbations with antibiotics. 40,47,48 in severe exacerbations (eg, patients in intensive care units), antibiotics reduce short-term mortality and treatment failure rates. 1 practice guidelines recommend using antibiotics for patients with increased sputum purulence and either increased sputum volume or increased dyspnea, patients with all three of these symptoms, or patients who require mechanical ventilation. 1 the most common bacterial pathogens isolated during copd exacerbations are haemophilus influenzae, streptococcus pneumonia, and moraxella catarrhalis. 40 appropriate antibiotic selections in copd exacerbations are included in table 15–4. Local resistance patterns should be considered when selecting an antimicrobial regimen. Other therapies patients must be educated on the importance of smoking cessation both during and after an exacerbation.

sat essay practice The term aki has replaced the term acute renal failure (arf) because it more completely encompasses the entire spectrum of acute injury to the kidney, eli lilly cialis bph from mild changes in kidney function to end-stage kidney disease requiring renal replacement therapy (rrt). Furthermore, the definition of arf was inconsistent in the literature. 1 efforts to standardize the definition of arf led to a change in terminology to aki and development of a consensus definition. Aki is defined as an increase in serum creatinine (scr) of at least 0. 3 mg/dl (27 μmol/l) within 48 hours, a 50% increase in baseline scr within 7 days, or a urine output of less than 0. 5 ml/kg/hour for at least 6 hours. Only one criterion needs to be met for diagnosis of aki. 2 prerenal aki occurs in approximately 10% to 25% of patients diagnosed with aki and is characterized by reduced blood delivery to the kidney. A common cause is intravascular volume depletion due to conditions such as hemorrhage, dehydration, or gi fluid losses. Early volume restoration can prevent progression and improve recovery because no structural damage to the kidney has occurred. 6 conditions of reduced cardiac output (eg, congestive heart failure [chf], myocardial infarction) and hypotension can also reduce renal blood flow, resulting in decreased glomerular perfusion and prerenal aki. With a mild to moderate decrease in renal blood flow, intraglomerular pressure is maintained by dilation of afferent arterioles (arteries supplying blood to the glomerulus), constriction of efferent arterioles (arteries removing blood from the glomerulus), and redistribution of renal blood flow to the oxygen-sensitive renal medulla. Drugs may cause a functional aki when they interfere with these autoregulatory mechanisms. Nonsteroidal anti-inflammatory drugs (nsaids) impair prostaglandin-mediated dilation of afferent arterioles. Angiotensin-converting enzyme (ace) inhibitors and angiotensin receptor blockers (arbs) inhibit angiotensin ii–mediated efferent arteriole vasoconstriction and cause prerenal aki in 6% to 38% of treated patients. 6 the calcineurin inhibitors cyclosporine and tacrolimus, particularly in high doses, are potent renal vasoconstrictors. All these agents can reduce intraglomerular pressure, with a resultant decrease in gfr. Prompt discontinuation of the offending drug can often return kidney function to normal. Other causes of prerenal aki are renovascular obstruction (eg, renal artery stenosis), hyperviscosity syndromes (eg, multiple myeloma), and systemic vasoconstriction (eg, hepatorenal syndrome). A epidemiology and etiology approximately 5% to 7% of all hospitalized patients develop aki. Aki is 5 to 10 times more prevalent in the hospital setting than in the community setting. 3 about 5% to 20% of critically ill patients develop aki,3 and 30% to 40% of survivors progress to chronic kidney disease (ckd). 4 despite improvements in the medical care of individuals with aki, mortality generally exceeds 15% for patients in general wards to 50% for icu patients. 5 pathophysiology there are three categories of aki. Prerenal, intrinsic, and postrenal aki. The pathophysiologic mechanisms differ for each of the categories.

(see figure 94–2) •• determine whether patient has insurance coverage for planned chemotherapy regimen and prescription coverage for supportive care medications. Assist patient in locating pharmacy to fill opioid prescription medications when needed. In addition, appropriate diagnostic scans (ie, ct scan, mri, or pet scan) should be evaluated once every three cycles. Patients should also have routine physical examinations with each cycle of chemotherapy to evaluate for any physical toxicity associated with chemotherapy such as neuropathies, fluid retention, palmar-plantar erythrodysesthesia, myelosuppression, or nausea/ vomiting. Unfortunately, most patients will eventually progress through all chemotherapy options, and supportive care measures should be provided to maintain patient comfort and quality of life. Common complications while developing a plan for treatment of advanced or progressive ovarian cancer include ascites, uncontrollable pain, and sbo. Precaution should be used in removal of ascites because of the potential complications associated with rapid fluid shifts. Liberal use of opioids to control pain is appropriate as ovarian cancer patients cope with pd and approaching end of life. Appropriate bowel regimens with laxatives and stool softeners should be used to prevent constipation. However, when a patient with a well-controlled bowel regimen presents with new onset of constipation, additional workup is required before altering the bowel regimen. In ovarian cancer patients, sbo is a common complication of progressive disease. Care plan development. •• provide appropriate patient education on respective chemotherapy agents that will be given for treatment of ovarian cancer. What each chemotherapy agent is, route, frequency, and duration it will be administered and how it works to treat cancer. •• explain the plan and frequency for monitoring response to treatment and treatment intent- curative verses palliative (relief of symptoms). •• what side effects to expect during chemotherapy?. Precautions to take to prevent infection and how to monitor for signs and symptoms of infection. Neuropathy, electrolyte wasting and bowel habits. •• develop appropriate plan for prevention and treatment of nausea and vomiting based on emetogenic potential of regimen. Discuss nonpharmacologic interventions such as diet choices and frequency of meals. Also provide information on any drug or food interactions with chemotherapy to avoid •• review pharmacological and non-pharmacological recommendations for blood clot prevention postsurgery. Follow-up evaluation. •• patient should be evaluated 5 to 6 weeks after surgery. Evaluate wound healing, pain control/resolution, and determine if adjuvant chemotherapy required. •• review laboratory values prior to each new cycle of chemotherapy. Recommend appropriate dose adjustments or changes for altered organ function, prolonged myelosuppression, or unacceptable toxicity. •• assess tumor response to chemotherapy once every 3 months.
