1. Which medication is a direct oral anticoagulant (DOAC) that does not require
routine INR monitoring?
A) Warfarin
B) Apixaban
C) Enoxaparin
D) Aspirin
Rationale: Apixaban is a direct factor Xa inhibitor used for stroke prevention in
nonvalvular atrial fibrillation. DOACs do not require routine INR monitoring unlike
warfarin.
2. Which medication is the preferred anticoagulant for a patient with mechanical
mitral valve?
A) Apixaban
B) Warfarin
C) Rivaroxaban
,D) Dabigatran
Rationale: Warfarin is the preferred anticoagulant for patients with mechanical heart
valves. DOACs are contraindicated in this population due to increased risk of
thromboembolic events.
3. What is the target INR for a patient with a mechanical mitral valve?
A) 1.5-2.0
B) 2.0-3.0
C) *2.5-3.5*
D) 3.0-4.0
Rationale: The target INR for a mechanical mitral valve is 2.5-3.5. Higher targets are
needed due to the increased thrombogenicity of the mitral position.
4. Which medication is a factor Xa inhibitor?
A) Rivaroxaban
B) Dabigatran
C) Warfarin
D) Heparin
Rationale: Rivaroxaban is a direct factor Xa inhibitor. Dabigatran is a direct thrombin
inhibitor. Warfarin inhibits vitamin K-dependent clotting factors. Heparin enhances
antithrombin III activity.
5. Which medication is a direct thrombin inhibitor?
,A) Rivaroxaban
B) Dabigatran
C) Warfarin
D) Heparin
Rationale: Dabigatran is a direct thrombin inhibitor. It is used for stroke prevention in
atrial fibrillation and treatment of DVT/PE.
6. Which medication is the antidote for dabigatran?
A) Protamine sulfate
B) Idarucizumab
C) Vitamin K
D) Fresh frozen plasma
Rationale: Idarucizumab is a monoclonal antibody fragment that binds to dabigatran
and reverses its anticoagulant effect. It is used in life-threatening bleeding or before
emergency surgery.
7. Which medication is the antidote for rivaroxaban and apixaban?
A) Idarucizumab
B) Andexanet alfa
C) Vitamin K
D) Protamine sulfate
Rationale: Andexanet alfa is a recombinant modified factor Xa that reverses the
anticoagulant effect of factor Xa inhibitors like rivaroxaban and apixaban.
, 8. Which medication is associated with a risk of heparin-induced
thrombocytopenia (HIT)?
A) Warfarin
B) Heparin
C) Apixaban
D) Aspirin
Rationale: Heparin can cause heparin-induced thrombocytopenia (HIT), an immune-
mediated reaction that leads to platelet activation and thrombosis. Platelet counts should
be monitored.
9. What is the treatment for heparin-induced thrombocytopenia (HIT)?
A) Continue heparin and monitor platelets
B) Discontinue heparin and start argatroban or bivalirudin
C) Start warfarin immediately
D) Start aspirin
Rationale: HIT requires immediate discontinuation of heparin and initiation of a non-
heparin anticoagulant such as argatroban or bivalirudin. Warfarin should not be started
until platelets recover.
10. Which medication is associated with a risk of osteoporosis with long-term use?
A) Warfarin
B) Heparin
