A client with suspected congestive heart failure undergoes a chest X-ray. The nurse should anticipate which finding that may be indicative of CHF?

Narrowed mediastinum

Hyperinflated lungs

Cardiomegaly

Normal cardiac silhouette

Answer and Explanation

The Correct Answer is C

A) This choice is incorrect because a narrowed mediastinum is not a characteristic finding in congestive heart failure. The mediastinum is the central region of the chest, and its width is not specifically related to CHF.

B) This choice is incorrect because hyperinflated lungs are a characteristic finding in chronic obstructive pulmonary disease (COPD), not congestive heart failure.

C) This choice is correct. Cardiomegaly, an enlarged heart, is a common finding in congestive heart failure. The heart may appear enlarged on a chest X-ray due to fluid accumulation and strain on the heart muscle.

D) This choice is incorrect because a normal cardiac silhouette on a chest X-ray would not be indicative of congestive heart failure. The presence of cardiomegaly is more suggestive of heart failure.

Correct Answer is D

Explanation

A) This choice is incorrect because while electrolyte imbalances can have cardiovascular implications, they are not directly associated with diabetes mellitus or congestive heart failure.

B) This choice is incorrect because left-sided heart failure is not directly related to uncontrolled diabetes mellitus. However, diabetes can exacerbate heart failure if not well-controlled due to its impact on blood vessels and the heart.

C) This choice is incorrect because decreased afterload is not directly related to uncontrolled diabetes mellitus. Afterload refers to the resistance the heart has to overcome to eject blood into the circulation.

D) This choice is correct. Uncontrolled diabetes mellitus can lead to microvascular damage, particularly in the small blood vessels of the heart. This damage can contribute to heart muscle dysfunction and congestive heart failure. Diabetes is a significant risk factor for developing heart failure.

Questions

A. Restricting all physical activity to prevent strain on the heart. B. Weighing themselves once a week and reporting sudden weight gain. C. Consuming a high-sodium diet to increase fluid retention. D. Taking prescribed medications only when symptoms worsen.

Correct Answer is B

Explanation

A) This choice is incorrect because restricting all physical activity is not recommended for clients with congestive heart failure. Regular, moderate exercise can be beneficial for heart health when appropriately prescribed by the healthcare provider.

B) This choice is correct. Regularly weighing themselves, ideally daily, and reporting sudden weight gain to the healthcare provider is essential for clients with congestive heart failure. Sudden weight gain may indicate fluid retention, a worsening of heart failure, or medication non-compliance.

C) This choice is incorrect because a high-sodium diet can worsen fluid retention and exacerbate congestive heart failure symptoms. The client should follow a low-sodium diet to manage fluid balance.

D) This choice is incorrect because taking prescribed medications only when symptoms worsen is not appropriate for congestive heart failure management. The client should take prescribed medications as directed by the healthcare provider, even when feeling well, to prevent symptom exacerbation and improve heart function.
