A client with atrial fibrillation is receiving a continuous heparin infusion at 1000 units/hr. The nurse determines that the client is receiving the therapeutic effect based on which results?

ExplanationCommon laboratory ranges for activated partial thromboplastin time (aPTT) are 30 to 40 seconds. Because the aPTT should be 1.5 to 2.5 times the normal value, the client’s aPTT would be considered therapeutic if it was 60 seconds. Prothrombin time assesses response to warfarin therapy.
