Question 1 of 5
A charge nurse is teaching a group of nurses about the antagonist action of reversal medications. For each medication listed below, click to specify the expected reversal agent.
| Options | Glucagon | Protamine sulfate | Vitamin K | Andexanet alfa |
|---|---|---|---|---|
| Warfarin: Vitamin K | ||||
| Heparin: Protamine sulfate | ||||
| Rivaroxaban: Andexanet alfa | ||||
| Beta Blockers: Glucagon |
Correct Answer: A,B,C,D
Rationale:
To select the correct answer , we need to understand the mechanism of action of each medication and its corresponding reversal agent. Warfarin inhibits Vitamin K-dependent clotting factors, so Vitamin K is used to reverse its effects. Heparin is neutralized by Protamine sulfate. Rivaroxaban, a factor Xa inhibitor, is reversed by Andexanet alfa. Beta blockers, like propranolol, are antagonized by Glucagon.
Therefore, the correct answer includes the reversal agents for Warfarin, Heparin, Rivaroxaban, and Beta Blockers, making options A, B, C, D the correct choices.
