@nurseucynclexhub: PT/INR vs aPTT can be confusing because both evaluate clotting—but they are connected to different anticoagulants. PT/INR is commonly used to monitor warfarin, while aPTT or anti-Xa may be used to monitor an IV unfractionated heparin infusion. Knowing which lab goes with which medication is an important nursing and NCLEX concept. #NursingStudent #NursingSchool #healthcare #LearnOnTikTok
Quick memory trick:
Warfarin → INR
Unfractionated heparin → aPTT or anti-Xa
The higher the clotting time, the longer the blood takes to clot and the greater the potential bleeding risk.
