A client with a history of alcohol abuse and malnutrition is admitted with signs and symptoms of congestive heart failure. Which factor is likely a precipitating cause of the client's condition?

A) This choice is incorrect because while digoxin can impact liver function, it is not the primary parameter to be monitored. Liver function tests may be performed periodically to assess liver health during digoxin therapy.

B) This choice is incorrect because serum sodium levels are not directly impacted by digoxin. However, electrolyte imbalances, including hypokalemia, can potentiate digoxin toxicity, so potassium levels should be monitored.

C) This choice is correct. Digoxin is a cardiac glycoside that can impact renal function. Monitoring urine output is essential to assess kidney function and the client's response to the medication.

D) This choice is incorrect because blood glucose levels are not specifically impacted by digoxin. However, hypokalemia resulting from digoxin therapy can cause alterations in glucose metabolism, so blood glucose levels should be monitored in clients taking digoxin.

Questions

A) This choice is incorrect because an electrocardiogram (ECG) is a valuable diagnostic tool for assessing the heart's electrical activity and rhythm, but it is not the gold standard for diagnosing CHF. It can provide information about possible cardiac hypertrophy or rhythm disturbances associated with heart failure.

B) This choice is incorrect because a chest X-ray is helpful in evaluating heart size and the presence of pulmonary congestion, but it is not the gold standard for diagnosing CHF.

C) This choice is correct. An echocardiogram is the gold standard for diagnosing CHF. It uses ultrasound waves to assess the heart's structure and function, including ejection fraction and valve function, providing critical information to confirm the diagnosis of heart failure.

D) This choice is incorrect because a brain natriuretic peptide (BNP) level is a blood test that can aid in the diagnosis of CHF. Elevated BNP levels indicate heart strain, but it is not the gold standard for diagnosing CHF.
