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.
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.

Correct Answer is A
Explanation
The correct answer is choice A. Increased pulse rate.
An aPTT of 90 seconds is much higher than the normal range of 30-40 seconds, which means the blood takes longer to clot and the client is at risk of bleeding. An increased pulse rate is a sign of blood loss and shock.
Choice B is wrong because increased blood pressure is not a sign of bleeding, but rather a sign of hypertension or stress.
Choice C is wrong because decreased temperature is not a sign of bleeding, but rather a sign of hypothermia or infection.
Choice D is wrong because decreased respiratory rate is not a sign of bleeding, but rather a sign of respiratory depression or sedation.
Correct Answer is D
Explanation
Lovastatin is a lipid-lowering medication that belongs to the statin drug class.
It is used to treat and prevent coronary heart disease and hypercholesterolemia.
Before starting therapy with lovastatin, liver function tests should be performed to establish a baseline and monitor for any potential adverse effects on the liver.
Choice A is wrong because Western blot analysis, is not the correct answer because it is a laboratory technique used to detect specific proteins in a sample, not to monitor liver function.
Choice B is wrong because Pancreatic enzymes, is not the correct answer because it refers to enzymes produced by the pancreas that aid in digestion, not liver function.
Choice C is wrong because Exercise electrocardiography, is not the correct answer because it is a diagnostic test used to assess the heart’s response to physical stress, not liver function.
