Correct Answer: B

Rationale: The correct answer is B: Suppression of airway mucus production. Corticosteroids like methylprednisolone are known to suppress airway mucus production. This action helps in reducing inflammation and swelling in the airways, making breathing easier for individuals with conditions like asthma or COPD. Choices A, C, and D are incorrect. Suppression of beta2 receptors is more related to beta-blockers, fortification of bones is associated with medications like bisphosphonates, and suppression of candidiasis is not a typical pharmacologic action of methylprednisolone.

Correct Answer: B

Rationale: When an IV site appears infiltrated, it indicates that the medication is leaking into the surrounding tissues. In such a situation, the infusion should be stopped immediately to prevent further tissue damage. Choice A is incorrect because slowing the infusion would still allow the medication to leak into the tissues. Choices C and D are also incorrect as applying compresses can exacerbate the tissue damage caused by infiltration.

Correct Answer: B

Rationale: The correct answer is B. The nurse should instruct the client to avoid excessive intake of caffeinated beverages as they can interfere with lithium levels. Option A is incorrect as lithium is usually recommended to be taken on an empty stomach. Option C is not directly related to lithium therapy. Option D is not a typical instruction for lithium therapy.

Correct Answer: A

Rationale: Correct answer: Before administering blood products, the client's temperature must be assessed to establish a baseline and monitor for transfusion reactions. Choice B is incorrect because documenting client response should occur after administering the blood products. Choice C is incorrect as priming IV tubing with 0.45% sodium chloride is not directly related to assessing the client before administering blood products. Choice D is incorrect because administering epinephrine is not a routine action before administering blood products.

Correct Answer: C

Rationale: The correct answer is C: Infusion reaction. Vancomycin can cause infusion reactions like 'Red Man Syndrome,' which involves rashes, flushing, tachycardia, and hypotension. Hepatotoxicity (choice A) is not a common adverse effect of vancomycin. Constipation (choice B) is not typically associated with vancomycin use. Immunosuppression (choice D) is not a direct adverse effect of vancomycin therapy.
