A new patient comes to see the primary care NP with fever, mild dehydration, and dysuria with flank pain
The patient tells the NP that a previous provider always prescribed trimethoprim-sulfamethoxazole and wonders why a urine culture is necessary because this antibiotic has worked in the past. The NP should tell this patient that a culture is necessary to help determine: a. the correct dose of the antibiotic.
b. whether antibiotic resistance is occurring.
c. whether multiple organisms are causing infection.
d. the length of antibiotic therapy needed to treat the infection.
B
Antibiotic resistance can occur when bacteria are repeatedly exposed to antibiotic agents. Even though a particular antibiotic is effective for a certain type of infection, resistance can occur, and another antibiotic may be necessary. A culture and sensitivity test is essential for choosing the right antibiotic. The culture and sensitivity test does not help determine the dose or the length of therapy.
