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 hypertension is not a common side effect of digoxin. Digoxin is used to treat heart failure and can help control blood pressure in some cases.

B) This choice is incorrect because hyperkalemia (elevated potassium levels) is not a common side effect of digoxin. In fact, digoxin can sometimes cause hypokalemia (low potassium levels) as a side effect.

C) This choice is correct. Bradycardia (slow heart rate) is a common side effect of digoxin. Digoxin works by increasing the force of the heart's contractions and can slow down the heart rate. Clients taking digoxin should have their heart rate monitored regularly, and the healthcare provider should be notified if the heart rate is below the prescribed parameters.

D) This choice is incorrect because respiratory alkalosis is not a common side effect of digoxin. Digoxin does not directly affect the respiratory system.

Questions

A. "CHF is primarily caused by infections and viral illnesses." B. "The leading causes of CHF are hypertension and coronary artery disease." C. "CHF is often a result of excessive physical exertion and overworking the heart." D. "The main cause of CHF is anemia and low red blood cell count."

Correct Answer is B

Explanation

A) This choice is incorrect because while infections and viral illnesses can contribute to heart failure in some cases, they are not the leading causes of CHF. Hypertension and coronary artery disease are more common risk factors.

B) This choice is correct. Hypertension (high blood pressure) and coronary artery disease (narrowing or blockage of the heart's blood vessels) are the leading causes of CHF. Both conditions place increased stress on the heart and can lead to heart muscle damage and failure.

C) This choice is incorrect because while excessive physical exertion and overworking the heart can contribute to heart failure, they are not the primary causes of CHF. Underlying conditions like hypertension and coronary artery disease are more significant risk factors.

D) This choice is incorrect because anemia and low red blood cell count can impact heart function, but they are not the main causes of CHF. Hypertension and coronary artery disease are more commonly associated with the development of CHF.
