Section I: Core Principles of Stewardship (Questions 1–15)
1. Which of the following best defines antibiotic stewardship?
a) Prescribing the broadest-spectrum antibiotic to ensure coverage
b) Limiting all antibiotic use to inpatient settings only
c) Coordinated interventions to improve antibiotic use, optimizing clinical
outcomes while minimizing harm
d) Requiring infectious disease consultation for all antibiotics
Rationale: Stewardship aims to maximize benefit (cure) and minimize harm
(resistance, adverse effects, C. diff).
2. The single most important driver of antibiotic resistance in human medicine is:
a) Agricultural antibiotic use
b) Overuse and misuse of antibiotics in humans
c) Lack of new antibiotic development
d) Patient non-adherence to therapy
Rationale: While agriculture contributes, human overuse (inappropriate
prescribing for viral infections, too broad spectrum) is the primary driver.
3. According to the CDC’s Core Elements of Outpatient Stewardship (2025
update), which action is most effective for reducing inappropriate prescribing for
acute bronchitis?
a) Post-visit patient satisfaction surveys
b) Delayed antibiotic prescriptions (backup prescriptions)
,c) Routine use of procalcitonin for all cough illnesses
d) Mandatory infectious disease approval for all antibiotics
Rationale: Delayed prescribing (with instructions to fill only if symptoms worsen
after 3 days) reduces inappropriate use without harming satisfaction.
4. A patient insists on antibiotics for “green nasal discharge” of 4 days. The best
stewardship approach is:
a) Prescribe amoxicillin to maintain patient trust
b) Explain that green discharge is normal in viral rhinosinusitis and offer
symptom management
c) Order a sinus X-ray before deciding
d) Prescribe azithromycin as a shorter course
Rationale: Purulent discharge alone does not indicate bacterial infection; acute
rhinosinusitis is viral in >98% of cases <10 days.
5. The “antibiotic time-out” refers to:
a) Stopping all antibiotics after 48 hours regardless of culture results
b) A formal reassessment of antibiotic need, choice, and duration after 48–72
hours
c) A mandatory 24-hour delay before first dose
d) A policy requiring pre-authorization for all IV antibiotics
Rationale: Time-out at 48–72 hours allows de-escalation, stopping, or narrowing
based on culture and clinical response.
6. Which metric is most useful for measuring outpatient antibiotic stewardship
success?
a) Total number of antibiotic prescriptions written
b) Rate of antibiotic prescribing for acute bronchitis (target <10%)
c) Average cost per prescription
d) Number of patients who ask for antibiotics
Rationale: Bronchitis should rarely need antibiotics; this is a key quality measure
in national dashboards (e.g., CDC AUR module).
7. A hospital implements a “pre-authorization for carbapenems” policy. This is an
example of:
a) Prospective audit and feedback
b) Formulary restriction with prior approval
, c) Academic detailing
d) Antibiotic time-out
Rationale: Restricting certain broad-spectrum agents requires ID/pharmacy
approval before dispensing.
8. Which patient factor is associated with the highest risk of antibiotic-
associated C. difficile infection?
a) Age <2 years
b) Age >65 years with recent clindamycin or fluoroquinolone use
c) History of penicillin allergy
d) Chronic NSAID use
Rationale: Advanced age and high-risk antibiotics (clindamycin, FQs, broad-
spectrum cephalosporins) are major risk factors.
9. The WHO AWaRe classification groups antibiotics into:
a) First-line, second-line, third-line
b) Access, Watch, Reserve
c) Narrow, broad, ultra-broad
d) Oral, IV, topical
Rationale: AWaRe (Access – low resistance potential; Watch – higher resistance
risk; Reserve – last-line) guides stewardship.
10. In 2026, the FDA approved a rapid diagnostic test that detects 45 respiratory
pathogens in <1 hour. Stewardship implications include:
a) Automatically treat all detected organisms
b) Use results to stop unnecessary antibiotics when viral only
c) Always add empiric MRSA coverage
d) Repeat testing daily until symptoms improve
Rationale: Rapid multiplex PCR can rule out bacterial pathogens, enabling
antibiotic discontinuation.
11. Which antibiotic course duration is now recommended for uncomplicated
community-acquired pneumonia (CAP) in a responding patient?
a) 10–14 days
b) 5 days
c) 7–10 days
d) Until complete symptom resolution
