Answer to Question 1
ANS: B
CHF, commonly occurring in the elderly or in patients with past myocardial infarctions or cardiomyopathy, can often present with complaints of fatigue, decreased activity tolerance, and/or shortness of breath. A patient with a history of hypertension and hyperlipidemia indicates cardiovascular disease that predisposes to heart failure with age. The signs of heart failure include cough, shortness of breath with exertion, S3 and S4 heart sounds, pulmonary crackles, ascites, hepatomegaly and ankle edema.
Answer to Question 2
ANS: A
Patients with mild renal dysfunction are generally asymptomatic, but as the disease progresses, vague symptoms appear. Fatigue and weakness are early signs, as are decreased cognitive functioning and irritability. Patients may complain of nocturia, which is due to the kidney not concentrating the urine at night. Many of these early signs are nonspecific, and patients often pass them off as a normal part of aging. GI complaints, such as nausea, vomiting, and anorexia, are common and contribute to the muscle wasting and fatigue. Patients may complain of a metallic taste in the mouth. Hypertension may develop from fluid overload and can result in CHF. Pericarditis may develop, producing a friction rub. Neurological symptoms include muscle cramps and twitching, peripheral neuropathy, difficulty concentrating, and sleep disturbances.
