The health care provider prescribes the antibiotic tetracycline HCl for an adult client who arrived at an outpatient clinic. Which instruction should the nurse include in the teaching plan for this client?

Choice A reason: Tetracycline HCl can cause photosensitivity, which increases the risk of sunburn and skin damage. The client should avoid direct sunlight and use sunscreen and protective clothing while taking the drug. Choice B reason: Orange juice is acidic and can decrease the absorption of tetracycline HCl. The client should take the drug with water and avoid acidic foods and beverages. Choice C reason: Serum drug levels are not routinely monitored for tetracycline HCl. The client should follow the prescribed dosage and duration of the therapy. Choice D reason: Milk and antacids can interfere with the absorption of tetracycline HCl. The client should take the drug at least 1 hour before or 2 hours after meals and avoid dairy products and antacids.
