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?

Alcohol abuse

Malnutrition

Sedentary lifestyle

Occupational exposure to toxins

Answer and Explanation

The Correct Answer is A

A) This choice is correct. Alcohol abuse can lead to dilated cardiomyopathy, a condition in which the heart becomes enlarged and weakened, contributing to congestive heart failure. Chronic alcohol consumption can cause toxic effects on the heart muscle, leading to impaired pumping function.

B) This choice is incorrect because malnutrition, while it can impact overall health, is not a direct precipitating cause of congestive heart failure. However, malnutrition can exacerbate heart failure symptoms and weaken the heart further.

C) This choice is incorrect because a sedentary lifestyle can be a risk factor for heart disease, including congestive heart failure, but it is not a direct precipitating cause of the client's condition in this scenario.

D) This choice is incorrect because occupational exposure to toxins can have health implications, but it is not directly related to the client's signs and symptoms of congestive heart failure in this case.

Correct Answer is B

Explanation

A) This choice is incorrect because a high-pitched, scratchy sound heard during inhalation is called a pleural friction rub and is associated with pleuritis or inflammation of the pleura, not congestive heart failure.

B) This choice is correct. An S3 heart sound is an extra heart sound heard immediately after S1 and S2, often described as a "ventricular gallop." It is associated with congestive heart failure and indicates increased fluid volume and strain on the ventricles.

C) This choice is incorrect because a prolonged, whooshing sound heard during systole is a heart murmur, which can be caused by various conditions, but it is not specific to the presence of an S3 sound.

D) This choice is incorrect because an irregular heart rhythm with varying intensity is characteristic of cardiac arrhythmias or irregular heartbeats and is not specific to the presence of an S3 sound.

A. "Consume a diet high in sodium to prevent fluid retention." B. "Limit your intake of fluids to 1 liter per day." C. "Restrict your intake of potassium-rich foods." D. "Follow a low-sodium diet to reduce fluid overload."

Correct Answer is D

Explanation

A) This choice is incorrect because consuming a diet high in sodium would exacerbate fluid retention in congestive heart failure. Clients with CHF should follow a low-sodium diet to reduce fluid overload and manage edema.

B) This choice is incorrect because limiting fluid intake to 1 liter per day is too restrictive and may lead to dehydration. Fluid restriction is essential for some clients with CHF, but the specific limit should be determined by the healthcare provider based on the client's individual needs.

C) This choice is incorrect because while potassium intake may need to be monitored, restricting potassium-rich foods is not a universal instruction for clients with CHF. It depends on the client's overall potassium levels and specific medication regimen.

D) This choice is correct. Following a low-sodium diet is essential for clients with congestive heart failure to reduce fluid retention and manage symptoms of fluid overload.
