The client is receiving heparin (Heplock). The nurse will monitor which laboratory results to evaluate therapeutic response?
1. INR
2. aPTT
3. BNP
4. PT
Correct Answer: 2
Rationale 1: INR is incorrect because it should be monitored for a client receiving Coumadin therapy.
Rationale 2: To avoid serious adverse effects, drug therapy with coagulation-modifier drugs is individualized to each patient and must be carefully monitored. For heparin, the activated partial thromboplastin time (aPTT) is used.
Rationale 3: BNP is incorrect because this lab result does not pertain to clotting.
Rationale 4: PT is incorrect because it should be monitored for a client receiving Coumadin therapy.
