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 B
Explanation
A. If he misses a dose, he should double the dose at the next scheduled time: This statement is incorrect. Doubling the dose of warfarin after missing a dose can significantly increase the risk of bleeding due to excessive anticoagulation. The nurse should emphasize the importance of taking the medication as prescribed and what to do if a dose is missed, such as contacting the healthcare provider for guidance.
B. The client should use an electric razor while on this medication: This statement is correct. Warfarin is an anticoagulant medication that can increase the risk of bleeding. Therefore, it's essential for patients taking warfarin to avoid activities that may increase the risk of injury or bleeding, such as shaving with a traditional razor that can cause cuts or nicks. Using an electric razor reduces this risk.
C. Mild nosebleeds are common during initial treatment: This statement is not entirely accurate. While warfarin can increase the risk of bleeding, including nosebleeds, it's not necessarily common during the initial treatment phase. However, patients should be aware of signs of bleeding and report them to their healthcare provider promptly.
D. Warfarin increases the risk for deep vein thrombosis: This statement is incorrect. Warfarin is actually prescribed to reduce the risk of blood clots, including deep vein thrombosis (DVT), pulmonary embolism (PE), and stroke, in patients who are at risk for these conditions. It works by inhibiting the formation of blood clots. Therefore, it does not increase the risk of DVT; rather, it decreases it.
Correct Answer is A
Explanation
A. LMWHs produce a more stable effect on coagulation; thus, fewer lab tests are needed: Correct LMWHs have a more predictable anticoagulant response compared to unfractionated heparin, resulting in a more stable effect on coagulation. Because of their predictable response, routine monitoring of coagulation parameters, such as activated partial thromboplastin time (aPTT), is typically not required with LMWH therapy, unlike with unfractionated heparin.
B. LMWHs may be given by the oral route: Incorrect. LMWHs are administered by the subcutaneous route.
C. LMWHs have a short duration of action: Incorrect. LMWHs have a longer duration of action compared to unfractionated heparin.
D. LMWHs possess greater anticoagulant activity: incorrect. LMWHs generally have less potent anticoagulant activity compared to unfractionated heparin, but their more predictable response and longer half-life make them advantageous in many clinical scenario
