1. A client is receiving warfarin therapy. Which of the following findings should the nurse identify as an adverse effect of warfarin?

Correct answer: B

Rationale: Epistaxis, or nosebleeds, can be an indication of excessive anticoagulation while on warfarin therapy. Warfarin is a blood thinner that helps prevent blood clots. Epistaxis can occur as a result of the blood-thinning effects of warfarin, leading to increased bleeding tendencies, including nosebleeds. Nausea, diarrhea, and dyspepsia are not typically associated with warfarin therapy; therefore, they are not the adverse effects the nurse should identify in a client receiving warfarin.

2. A healthcare professional is reviewing laboratory findings and notes that a client's plasma Lithium level is 2.1 mEq/L. Which of the following is an appropriate action by the healthcare professional?

Correct answer: A

Rationale: Performing immediate gastric lavage is the appropriate action for a client with severe lithium toxicity, indicated by a plasma lithium level of 2.1 mEq/L. Gastric lavage can help reduce the client's lithium level by removing the unabsorbed drug from the stomach.

3. A female client with tobacco use disorder is being educated by a nurse about Nicotine replacement therapy. Which of the following statements by the client shows understanding of the teaching?

Correct answer: A

Rationale: The correct answer is A. The client should avoid eating or drinking 15 minutes prior to and while chewing the nicotine gum. Choice B is incorrect because there is no specified timeline for stopping nicotine gum use. Choice C is incorrect because nicotine gum is not recommended during pregnancy. Choice D is incorrect as the client should chew the nicotine gum slowly for about 30 minutes, not quickly for 15 minutes.

4. When teaching a client how to use nitroglycerin transdermal ointment for angina, which instruction should the nurse include?

Correct answer: A

Rationale: The correct instruction is to remove the prior dose before applying a new dose. This helps prevent toxicity by ensuring the client does not inadvertently apply an excessive amount of nitroglycerin.

5. A client has a new prescription for radioactive iodine to treat Hyperthyroidism. Which of the following instructions should the nurse include?

Correct answer: B

Rationale: When a client undergoes radioactive iodine treatment for hyperthyroidism, they can emit radiation for a short time. To prevent radiation exposure to others, especially pregnant women, infants, and small children, clients should avoid close contact for about 1 week following therapy. This precaution is essential to protect vulnerable individuals from potential harm. Choice A is incorrect because a metallic taste in the mouth is not a common side effect of radioactive iodine treatment. Choice C is incorrect because administering iodine solution using a straw is not a standard practice in this treatment. Choice D is incorrect because taking thyroid replacement medication for 3 weeks after treatment is not a typical instruction associated with radioactive iodine therapy for hyperthyroidism.
