A client is undergoing an echocardiogram as part of the diagnostic workup for suspected pulmonary embolism. What information can an echocardiogram provide in this context?

A) Incorrect. Jaundice is a yellowing of the skin and sclera due to elevated bilirubin levels, which is not described in the client's symptoms.

B) Incorrect. Pallor refers to paleness of the skin, which is not consistent with the client's cyanosis.

C) Incorrect. Erythema refers to redness of the skin due to increased blood flow, which is not the best description of the client's symptoms.

D) Correct. Cyanosis is the bluish discoloration of the skin, lips, and nail beds due to decreased oxygen saturation in the blood, which is indicative of a severe oxygen deficit often seen in pulmonary embolism.

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.
