CBIC Antimicrobial Stewardship 4

Question 1

A patient is diagnosed with asymptomatic bacteriuria. Which ASP recommendation is appropriate for most patients?

Accepted Answer

No antibiotic treatment is warranted unless the patient is pregnant or undergoing urologic procedures

Answer

Treating asymptomatic bacteriuria in non-pregnant, non-surgical patients provides no clinical benefit and increases resistance and adverse effects.

Question 2

Which of the following best describes the concept of 'antibiotic stewardship' as defined by the CDC?

Accepted Answer

The coordinated interventions designed to improve and measure the appropriate use of antimicrobials by promoting selection of the optimal regimen

Answer

The CDC defines antibiotic stewardship as coordinated efforts to optimize antibiotic use, including the right drug, dose, route, and duration for each patient.

Question 3

Which biomarker is most useful for guiding antibiotic discontinuation in patients with suspected sepsis?

Accepted Answer

Procalcitonin (PCT)

Answer

Procalcitonin rises rapidly in bacterial infections and falls quickly with effective treatment, making serial PCT measurements useful for guiding antibiotic de-escalation and stopping decisions.

Question 4

Which of the following infections typically requires the shortest antibiotic course according to current evidence-based guidelines?

Accepted Answer

Uncomplicated lower urinary tract infection in women (3 days)

Answer

Uncomplicated cystitis in women is effectively treated with 3-day courses of trimethoprim-sulfamethoxazole or 5-day nitrofurantoin, one of the shortest validated antibiotic durations.

Question 5

In long-term care facilities (LTCFs), which of the following represents a common stewardship challenge?

Accepted Answer

High rates of antibiotic prescribing for asymptomatic bacteriuria based on urine dipstick results alone

Answer

LTCFs commonly over-treat asymptomatic bacteriuria detected incidentally on dipstick, contributing significantly to antibiotic overuse and resistance in this population.
