1. What is the antidote for Warfarin?

Correct answer: C

Rationale: Vitamin K is the antidote for Warfarin toxicity as it helps reverse the anticoagulant effects of Warfarin. Warfarin works by inhibiting vitamin K-dependent clotting factors, and administering vitamin K can replenish these factors, thereby counteracting the anticoagulant effects of Warfarin. Vitamin D, Vitamin C, and Vitamin B6 do not have the specific mechanism to counteract the anticoagulant effects of Warfarin, making them incorrect choices.

2. A client is being taught about Terbutaline. Which statement by the client indicates understanding of the teaching?

Correct answer: A

Rationale: The correct answer is A. Terbutaline works by blocking beta2-adrenergic receptors, leading to uterine smooth muscle relaxation and stopping contractions. Therefore, the client demonstrating understanding by recognizing that the medication will stop contractions is the most accurate response. Choices B, C, and D are incorrect because Terbutaline is primarily used to inhibit contractions in preterm labor, not prevent vaginal bleeding, promote blood flow to the baby, or increase prostaglandin production.

3. A client has a new prescription for Warfarin. The nurse should identify that the concurrent use of which of the following medications increases the client's risk of bleeding?

Correct answer: C

Rationale: The correct answer is Acetaminophen. Acetaminophen, especially in high doses, can increase the risk of bleeding in clients taking warfarin. Warfarin works by inhibiting the clotting factors dependent on vitamin K, so Vitamin K intake should be consistent but not excessive. Calcium carbonate and ranitidine do not significantly increase the risk of bleeding when used concurrently with Warfarin.

4. What is a serious adverse reaction to penicillin?

Correct answer: B

Rationale: The correct answer is B: Anaphylaxis. Anaphylaxis is a severe allergic reaction that can occur as a serious adverse reaction to penicillin. It is a life-threatening condition that requires immediate medical attention. Choices A, C, and D are incorrect. Liver failure is not a typical adverse reaction to penicillin, respiratory depression is more commonly associated with opioid medications, and edema is not a common severe adverse reaction to penicillin.

5. Which of the following drugs is associated with Stevens-Johnson syndrome?

Correct answer: D

Rationale: Stevens-Johnson syndrome is a severe skin reaction that can be associated with Ethosuximide.
