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 C

Explanation

A) This choice is incorrect because ACE inhibitors should not be taken with grapefruit juice. Grapefruit juice can interfere with the metabolism of the medication, leading to increased levels and potential side effects.

B) This choice is incorrect because the client should not adjust the dose of the ACE inhibitor without consulting their healthcare provider. Blood pressure should be monitored, but any dosage adjustments should be made by the healthcare provider based on the client's response to the medication.

C) This choice is correct. ACE inhibitors can cause a side effect of a persistent dry cough, and in some cases, difficulty breathing. The client should promptly report these symptoms to their healthcare provider for evaluation and possible adjustment of the medication regimen.

D) This choice is incorrect because while ACE inhibitors can increase potassium levels, avoiding foods high in potassium is not necessary unless specifically directed by the healthcare provider. The client should follow a balanced diet and inform the healthcare provider of any changes in their dietary habits.

A. Palpitations B. Angina pectoris C. Dyspnea on exertion D. Peripheral cyanosis

Correct Answer is C

Explanation

A) This choice is incorrect because palpitations refer to an abnormal awareness of the heart's beating, which is not described by the client.

B) This choice is incorrect because angina pectoris is chest pain or discomfort due to inadequate blood flow to the heart muscle. The client's complaint is related to physical activity causing fatigue and weakness, not chest pain.

C) This choice is correct. Dyspnea on exertion refers to shortness of breath or difficulty breathing that occurs with physical activity or exertion. The client's symptoms of feeling fatigued and weak after mild activity suggest exertional dyspnea, which is common in congestive heart failure.

D) This choice is incorrect because peripheral cyanosis is bluish discoloration of the skin and mucous membranes due to reduced blood flow, which is not described by the client.
