Discharge planning for the client prescribed tetracycline will include which instruction?

Correct Answer: C

Rationale: Tetracycline is a broad-spectrum antibiotic that can be rendered ineffective if taken with certain substances that interfere with its absorption. Dairy products, such as milk, contain calcium, which binds to tetracycline in the gastrointestinal tract, forming insoluble complexes that prevent the drug from being absorbed into the bloodstream. This interaction significantly reduces its therapeutic efficacy, making it crucial to instruct the client to avoid milk when taking the medication. Similarly, antacids (containing magnesium, aluminum, or calcium) and iron supplements also chelate tetracycline, decreasing its bioavailability, so choices A and B are incorrect and potentially harmful instructions. Reducing vitamin intake is unrelated to tetracycline's administration or efficacy, as vitamins do not typically interfere with its action unless specifically combined with minerals like iron or calcium. Therefore, the priority instruction is to avoid milk, ensuring the drug's effectiveness, which makes choice C the correct and most critical discharge teaching point.

Correct Answer: A

Rationale: Gentamicin risks ototoxicity, causing tinnitus (ringing, choice A), a serious sign needing immediate reporting to prevent hearing loss. Food doesn't apply'IV delivery. Calcium is irrelevant. Stopping early risks resistance. Reporting tinnitus aligns with gentamicin's toxicity profile, critical in therapy where auditory damage is irreversible, making A the key instruction.
