A client with atrial fibrillation secondary to mitral stenosis is receiving a heparin sodium infusion at 1000 units/hour and warfarin sodium (Coumadin) 7.5 mg at 5:00 PM daily. The morning laboratory results are as follows: activated partial thromboplastin time (aPTT) = 32 seconds; internationalized normalized ratio (INR) = 1.3. The nurse should plan to take which action based on the client's laboratory results?a) Collaborate with the health care provider (HCP) to discontinue the heparin infusion and administer the warfarin sodium as prescribed.b) Collaborate with the HCP to obtain a prescription to increase the heparin infusion and administer the warfarin sodium as prescribed.c) Collaborate with the HCP to withhold the warfarin sodium since the client is receiving a heparin infusion and the aPTT is within the therapeutic range.d) Collaborate with the HCP to continue the heparin infusion at the same rate and to discuss use of dabigatran etexilate (Pradaxa) in place of warfarin sodium.
