An 85-year-old resident with an indwelling urinary catheter has cloudy, foul-smelling urine. The resident is afebrile, has no new costovertebral angle tenderness, and exhibits no new behavioral changes. A nurse requests an order for an antibiotic. What is the consultant pharmacist's most appropriate recommendation based on antimicrobial stewardship principles?
-
A
Recommend against antibiotic therapy at this time, explaining that the findings represent asymptomatic bacteriuria per the Loeb criteria for catheterized residents.
-
B
Suggest a broad-spectrum antibiotic, such as a fluoroquinolone, to prevent the development of urosepsis.
-
C
Recommend obtaining a urinalysis and starting empiric antibiotic therapy immediately pending culture results.
-
D
Advise changing the urinary catheter and then reassessing the need for an antibiotic in 24 hours.
