The healthcare provider has ordered that a patient be placed on a hemostatic drug to control postoperative bleeding. Which of the following medications will most likely be given in this situation?
Trombin (Evithrom)
Aminocaproic acid (Amicar)
Aspirin
Tranexamic acid (Cyklokapron)
The Correct Answer is D
A. Trombin (Evithrom): Incorrect: Thrombin (also known as factor IIa) is not typically used as a hemostatic drug. It is involved in the final step of the coagulation cascade, converting fibrinogen to fibrin to form a stable clot. However, it is not administered directly as a medication.
B. Aminocaproic acid (Amicar): Aminocaproic acid is an antifibrinolytic agent commonly used to control bleeding. It works by inhibiting the breakdown of fibrin clots, thus promoting hemostasis. It is particularly useful in situations where excessive bleeding occurs due to impaired clot dissolution. However, tranexamic acid is generally considered more potent and has a longer-lasting effect, making it the preferred choice in many situations.
C. Aspirin: Incorrect: Aspirin is an antiplatelet medication that inhibits platelet aggregation. While it can reduce the risk of clot formation, it is not primarily used for controlling postoperative bleeding.
D. Tranexamic acid (Cyklokapron): Correct: Tranexamic acid is another antifibrinolytic agent that helps prevent excessive bleeding. It works by blocking the breakdown of fibrin clots. Tranexamic acid is commonly used in surgical settings to manage bleeding during and after procedures.

Correct Answer is D
Explanation
A. Diminished effect from warfarin: This is unlikely because displacement of warfarin from protein binding sites would increase its concentration in the bloodstream, potentially leading to increased anticoagulant effects and toxicity.
B. Diminished effect from paroxetine: This is also unlikely because displacement of paroxetine from protein binding sites would increase its concentration in the bloodstream, potentially leading to increased pharmacological effects and toxicity.
C. Increased effect, and toxicity from paroxetine: If paroxetine displaces warfarin from protein binding sites, it can increase the concentration of free warfarin in the bloodstream, leading to increased anticoagulant effects and potential toxicity.
D. Increased effect, and toxicity from warfarin: Correct. If warfarin is displaced from protein binding sites by paroxetine, it can increase the concentration of free warfarin in the bloodstream, leading to increased anticoagulant effects and potential toxicity.
Correct Answer is C
Explanation
A. Nausea and vomiting: Nausea and vomiting can occur with epoetin alfa, but it's not the most common side effect.
B. Orthostatic hypotension: This is not a common side effect of epoetin alfa. Orthostatic hypotension is a decrease in blood pressure upon standing.
C. Hypertension: Epoetin alfa stimulates the production of red blood cells. When the red blood cell count increases too quickly, it can lead to increased blood pressure, which is the most common adverse effect.
D. Dizziness: Dizziness can occur with epoetin alfa, but it's less common than hypertension.
