Final answer:
A nurse should recognize sulfonamides as a contraindication for a patient with a history of Stevens-Johnson syndrome when taking sulfamethoxazole-trimethoprim. However, based on the options provided (Prednisone, Furosemide, Lansoprazole, Digoxin), none contain sulfonamides and thus none are contraindicated based on the information given.
Step-by-step explanation:
The nurse should identify sulfonamides as a contraindication for a client with a history of Stevens-Johnson syndrome when taking sulfamethoxazole-trimethoprim. Stevens-Johnson syndrome is a severe hypersensitivity reaction that can occur as an allergic response to certain medications, including sulfonamides. Since sulfamethoxazole-trimethoprim is a combination of two medications (trimethoprim and a sulfonamide), the client should avoid all drugs within the sulfonamide class to prevent a potential recurrence of Stevens-Johnson syndrome.
Examining the provided medication options:
- Prednisone is a corticosteroid, not a sulfonamide.
- Furosemide is a loop diuretic and not related to sulfonamides.
- Lansoprazole is a proton pump inhibitor also not related to sulfonamides.
- Digoxin is a cardiac glycoside, unrelated to sulfonamides.
It's important to avoid exposure to all sulfa drugs and to be cautious of potential cross-reactivity with sulfa-related compounds. However, none of the medications listed in the question (A-D) contains sulfonamides, therefore, based on the information given, none would be contraindicated explicitly for a patient with a sulfonamide allergy.
