What assessment finding would indicate the patient's left-sided heart failure is worsening?

Increased jugular venous pressure.

Liver enlargement.

Increased pulse rate.

Increased crackles in lung fields.

Answer and Explanation

The Correct Answer is D

Choice A rationale

Increased jugular venous pressure is more commonly associated with right-sided heart failure, where blood backs up into the venous system.

Choice B rationale

Liver enlargement is also indicative of right-sided heart failure due to congestion of the liver blood vessels.

Choice C rationale

Increased pulse rate can occur in both left and right-sided heart failure but is not a specific indicator of worsening left-sided failure.

Choice D rationale

Increased crackles in lung fields indicate fluid accumulation in the lungs, a sign of worsening left-sided heart failure. Left-sided heart failure leads to pulmonary congestion due to inadequate pumping of blood from the left ventricle.
