Questions Verified and Provided with Complete A+ Graded Rationales Latest
Updated 2026
What type of precautions should a patient be on if they are receiving a heparin IV drip?
Bleeding precautions (sign on door, soft toothbrush, electric razor, etc.)
What labs should be monitored if a patient is on heparin therapy?
Monitor PTT and platelet counts. If these levels are decreased by 50% it can mean HIT (heparin
induced thrombocytopenia)
, What is the antidote for heparin?
Protamine sulfate
True or False: heparin does not dissolve clots that are already formed but will prevent further
clotting
True
True or False: there is a wide therapeutic index for heparin and a low risk for side effects.
False. There is a narrow therapeutic index and a high risk for side effects (I.e., decreasing ability
to clot in normal circumstances)
What labs are monitored for a patient on warfarin/coumadin?
PT-INR
(prothrombin time and internationalized ratio)
What labs are monitored for a patient on unfractionated heparin?
PTT and aPTT
(partial thromboplastin time and activated partial thromboplastin time)
