QUESTION 4

What is your plan for Coco at this time?

b) Discontinue the marbofloxacin since Coco's urinalysis results are improved, and initiate treatment with a urinary antiseptic such as methenamine.

c) Continue the marbofloxacin and have her return five to seven days after the last dose for a recheck urinalysis and culture.

d) Switch her antibiotic to enrofloxacin.
