A nurse is assessing a client who is receiving heparin therapy for deep-vein thrombosis.
Which of the following findings should indicate to the nurse that the therapy is effective?

Platelets within the expected reference range.

Decreased INR.

Presence of pedal pulses bilaterally.

Reduced calf circumference.

Answer and Explanation

The Correct Answer is D

Heparin therapy is used to prevent thrombus propagation and distal embolization while allowing the endogenous fibrinolytic system to dissolve existing clots in deep-vein thrombosis (DVT)1.

A reduction in calf circumference may indicate that the clot is dissolving and the therapy is effective.

Choice A is wrong because platelets within the expected reference range do not necessarily indicate that heparin therapy for DVT is effective.

Choice B is wrong because INR (International Normalized Ratio) is used to monitor warfarin therapy, not heparin therapy.

Choice C is wrong because the presence of pedal pulses bilaterally does not necessarily indicate that heparin therapy for DVT is effective.
