Answer to Question 1

ANS: C
The nurse should be most concerned that the patient is allergic to sulfa, because trimethoprim/sulfamethoxazole has a sulfa moiety and is contraindicated in patients allergic to sulfa.
Feeling tired is not a predominate concern.
The fact that the patient plays softball is not a concern, even though the potential exists for photosensitivity. The scenario does not specify whether she plays during the day or at night.
Taking trimethoprim/sulfamethoxazole for a UTI is appropriate for those who are not allergic to sulfa.

Answer to Question 2

ANS: A
The nurse would expect a potassium level of 5.5, because both captopril and spironolactone can cause hyperkalemia. Also, trimethoprim-sulfamethoxazole can cause hypersensitivity reactions in patients taking thiazide and loop diuretics and can affect the kidneys.
A potassium level of 3.5 is normal.
The sodium and chloride levels are normal.
