Which two teaching points should the nurse include while providing education to a client who is capable of pregnancy and has just been prescribed tetracycline? (Select all that apply.) Multiple options may be correct

A. "Take this medication with grapefruit juice.": Grapefruit juice can interact with certain medications by affecting liver metabolism, but tetracycline does not have a clinically significant interaction with grapefruit juice. Taking tetracycline with grapefruit juice is not recommended and may unnecessarily alter absorption. B. "Use a backup method of birth control.": Tetracycline can reduce the effectiveness of oral contraceptives, increasing the risk of unintended pregnancy. It is important to educate clients who are capable of becoming pregnant to use an additional or alternative method of contraception while taking this antibiotic and for a short period after completing the course. C. "Avoid sun exposure while taking this medication.": Tetracycline increases photosensitivity, making the skin more prone to sunburn. Clients should be instructed to limit sun exposure, wear protective clothing, and use broad-spectrum sunscreen to prevent severe phototoxic reactions during therapy. D. "This medication is used to treat fungal infections.": Tetracycline is a broad-spectrum antibiotic used to treat bacterial infections, not fungal infections. Antifungal medications, such as fluconazole or itraconazole, are used for fungal infections, making this statement inaccurate.
