The nurse is caring for a patient who has been taking a sulfa drug for a urinary tract infection (UTI). Which intervention is most important for the nurse to add to the patient's care plan?
a. Ambulate the patient q shift.
b. Ask the patient about a penicillin allergy.
c. Weigh the patient daily.
d. Increase fluid intake to 1.5 L/day.
D
With sulfa drugs, it is most important for the patient to maintain a fluid intake of at least 3000 mL (1.5 L) in order to prevent crystalluria and stone formation. Ambulation does not directly correlate to the sulfa drug in any way. Investigating an allergy is an assessment, not an interven-tion, and this action should occur prior to administering the first dose. Daily weights are impor-tant for tracking inputs and outputs, but it is not the priority intervention.
