Free AGACNP Exam Questions That Helps Candidates Pass

Spironolactone is a potassium-sparing diuretic, which can cause hyperkalemia. It is essential to monitor potassium levels during therapy to avoid life-threatening arrhythmias. While sodium, calcium, and magnesium are also important to monitor, potassium is the most critical due to the risk of hyperkalemia associated with spironolactone.

The patient's symptoms of leg swelling, heaviness, and discomfort that improve with elevation are most consistent with chronic venous insufficiency (CVI). CVI occurs when the veins in the legs are unable to effectively return blood to the heart, leading to fluid accumulation in the lower extremities. DVT and PAD present with different clinical features, while lymphedema typically causes non-pitting edema.

Beta-blockers reduce heart rate and are commonly used in heart failure management. Monitoring the heart rate is critical to avoid bradycardia, which can worsen symptoms or lead to other complications. Blood pressure, serum potassium, and serum creatinine should also be monitored but are secondary to heart rate monitoring in this case.

The patient's symptoms of right upper quadrant pain, fever, and nausea, along with elevated liver function tests, are suggestive of acute cholecystitis. This condition is often caused by gallstones obstructing the cystic duct, leading to inflammation of the gallbladder. Acute pancreatitis typically presents with epigastric pain and elevated pancreatic enzymes. Hepatitis may present with jaundice, and peptic ulcer disease typically causes epigastric pain, not right upper quadrant pain.

The patient's confusion, ataxia, and ophthalmoplegia are classic signs of Wernicke’s encephalopathy, a condition caused by thiamine deficiency, often seen in individuals with chronic alcohol use. This condition can progress to Korsakoff syndrome if left untreated. Acute stroke, seizure disorder, and alcohol withdrawal typically present with different symptoms.
