Correct Answer is B
Explanation
Choice A reason: Antibiotics are not likely to interact with corticosteroids, unless they are aminoglycosides, which can increase the risk of hypokalemia. However, most antibiotics do not affect the metabolism or efficacy of corticosteroids.
Choice B reason: Nonsteroidal anti-inflammatory drugs (NSAIDs) can interact with corticosteroids, as they both have anti-inflammatory and immunosuppressive effects. This can increase the risk of gastrointestinal bleeding, ulceration, and perforation. Therefore, the nurse should monitor the patient for signs of bleeding and advise the patient to avoid taking NSAIDs with corticosteroids.
Choice C reason: Opioid analgesics are not likely to interact with corticosteroids, unless they are codeine, which can decrease the clearance of corticosteroids. However, most opioid analgesics do not affect the metabolism or efficacy of corticosteroids.
Choice D reason: Antidepressants are not likely to interact with corticosteroids, unless they are monoamine oxidase inhibitors (MAOIs), which can increase the risk of hypertension and hypertensive crisis. However, most antidepressants do not affect the metabolism or efficacy of corticosteroids.
Correct Answer is B
Explanation
Choice A reason: Benzonatate is not the correct answer. Benzonatate is a cough suppressant that works by numbing the throat and lungs. It does not help in the removal of mucus.
Choice B reason: Guaifenesin is the correct answer. Guaifenesin is an expectorant that works by thinning and loosening the mucus in the airways. It helps in the removal of mucus by making it easier to cough up.

Choice C reason: Diphenhydramine is not the correct answer. Diphenhydramine is an antihistamine that works by blocking the effects of histamine, a chemical that causes allergy symptoms. It does not help in the removal of mucus.
