A nurse is caring for a client with congestive heart failure. Which assessment finding may indicate a potential precipitating factor for the client's condition?

Body mass index (BMI) of 22 kg/m²

Blood pressure of 120/80 mmHg

Fasting blood glucose level of 90 mg/dL

Serum cholesterol level of 240 mg/dL

Answer and Explanation

The Correct Answer is D

A) This choice is incorrect because a body mass index (BMI) of 22 kg/m² is within the normal range and is not directly associated with the development of congestive heart failure in this scenario.

B) This choice is incorrect because a blood pressure of 120/80 mmHg is within the normal range and does not indicate a direct precipitating factor for congestive heart failure in this case.

C) This choice is incorrect because a fasting blood glucose level of 90 mg/dL is within the normal range and is not directly associated with the development of congestive heart failure in this scenario.

D) This choice is correct. A serum cholesterol level of 240 mg/dL indicates high cholesterol, which is a risk factor for coronary artery disease. Coronary artery disease is a leading cause of congestive heart failure and may have contributed to the client's condition.

Correct Answer is D

Explanation

A) This choice is incorrect because serum electrolyte levels are not directly measured during an echocardiogram. They are typically assessed through a blood test and are not specific to evaluating heart function using ultrasound.

B) This choice is incorrect because blood pressure readings are not directly measured during an echocardiogram. Blood pressure is typically assessed using a sphygmomanometer and is not specific to evaluating heart function using ultrasound.

C) This choice is incorrect because oxygen saturation levels are not directly measured during an echocardiogram. Oxygen saturation is typically assessed using a pulse oximeter and is not specific to evaluating heart function using ultrasound.

D) This choice is correct. Ejection fraction (EF) is a parameter measured during an echocardiogram to assess the client's heart function. It represents the percentage of blood pumped out of the heart's left ventricle with each heartbeat and is an essential indicator of heart muscle efficiency and potential heart failure.

Questions

A. Narrowed mediastinum B. Hyperinflated lungs C. Cardiomegaly D. Normal cardiac silhouette

Correct Answer is C

Explanation

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.
