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: The correct answer is - A: Warfarin: Vitamin K, B: Heparin: Protamine sulfate, C: Rivaroxaban: Andexanet alfa, D: Beta Blockers: Glucagon.
- Warfarin inhibits Vitamin K-dependent clotting factors, so Vitamin K is used to reverse its effects.
- Heparin prolongs clotting time, and Protamine sulfate is used to neutralize its anticoagulant effects.
- Rivaroxaban is a Factor Xa inhibitor, and Andexanet alfa is a specific reversal agent for Factor Xa inhibitors like Rivaroxaban.
- Beta blockers can cause bradycardia or hypotension, and Glucagon can be used to reverse these effects by increasing heart rate and cardiac output.
Other choices are incorrect because they do not match the specific mechanism of action and reversal agent for each medication listed
