A client with suspected pulmonary embolism is undergoing a ventilation-perfusion (V/Q) scan. What is the purpose of this imaging test?

To visualize the heart's electrical activity

To assess lung function and oxygenation

To measure blood clotting time

To evaluate kidney function

Answer and Explanation

The Correct Answer is B

A) Incorrect. Visualizing the heart's electrical activity is typically done with an electrocardiogram (ECG), not a V/Q scan.

B) Correct. A ventilation-perfusion (V/Q) scan is used to assess lung function and oxygenation and to detect areas of the lung where blood flow and air ventilation do not match, which can indicate a pulmonary embolism.

C) Incorrect. Measuring blood clotting time is typically done using coagulation tests such as prothrombin time (PT) or activated partial thromboplastin time (aPTT).

D) Incorrect. Evaluating kidney function is not the primary purpose of a V/Q scan.

Correct Answer is B

Explanation

A) Incorrect. An echocardiogram does not visualize blood clots in the pulmonary arteries; it focuses on assessing heart function and structure.

B) Correct. An echocardiogram provides valuable information about heart valve function and heart structure, helping assess the impact of a pulmonary embolism on the heart.

C) Incorrect. Measurement of arterial blood gases (ABGs) is typically performed through blood sampling, not with an echocardiogram.

D) Incorrect. Echocardiograms do not evaluate lung function and ventilation; they primarily assess cardiac function.

A. "Avoid any form of physical activity to minimize the risk." B. "Maintain a diet high in cholesterol to prevent blood clots." C. "Completely eliminate all caffeine and alcohol from your diet." D. "Follow your healthcare provider's recommendations for anticoagulant therapy."

Correct Answer is D

Explanation

A) Incorrect. Avoiding all physical activity is not recommended. Clients should engage in appropriate physical activity, and the level of activity may be adjusted based on their condition.

B) Incorrect. A diet high in cholesterol is not a preventive measure for blood clots; in fact, it can contribute to cardiovascular risk factors.

C) Incorrect. While excessive caffeine and alcohol intake should be avoided, eliminating them completely is not a specific preventive measure for pulmonary embolism.

D) Correct. Following the healthcare provider's recommendations for anticoagulant therapy is crucial in preventing recurrent pulmonary embolism, especially in individuals with a history of the condition.
