Original practice questions
Infection
1. A patient receiving vancomycin needs what major monitoring consideration?
A. Only platelet size
B. Kidney function and exposure-based dosing when indicated
C. Only scalp temperature
D. Only serum glucose in all cases
Correct Answer: B — Kidney function and exposure-based dosing when indicated
Rationale: Vancomycin exposure and renal function monitoring help balance efficacy and toxicity.
2. An adult has recurrent UTIs after multiple antibiotic courses. Which approach is appropriate?
A. Continue indefinite empiric broad-spectrum treatment without review
B. Ignore drug-resistant cultures
C. Reassess diagnosis, cultures, risk factors, and preventive strategies
D. Treat every nonspecific symptom as a UTI
Correct Answer: C — Reassess diagnosis, cultures, risk factors, and preventive strategies
Rationale: Recurrent infection warrants targeted evaluation and stewardship rather than automatic repeated
antibiotics.
3. An outpatient experiences anaphylaxis to a prescribed antibiotic. Which practice reduces future risk?
A. Tell the patient to re-challenge unsupervised
B. Record the culprit drug and reaction details across care settings
C. Erase the allergy after one month
D. Document that the patient is nervous
Correct Answer: B — Record the culprit drug and reaction details across care settings
Rationale: Accurate, specific adverse-reaction documentation supports safer future prescribing.
4. Rationale check — consider this prescribing decision: A clinician considers macrolide therapy for a patient with
prolonged QT and other QT-prolonging drugs. What is prudent? Which rationale best supports the safest clinical
decision?
A. Certain macrolides can prolong QT, especially when combined with other risks.
B. Culture results, host factors, and resistance never influence treatment.
C. Antibiotics are indicated for every viral respiratory illness.
D. Longer and broader antibiotic therapy is always safer.

Correct Answer: A — Certain macrolides can prolong QT, especially when combined with other risks.
Rationale: This rationale accurately identifies the relevant pharmacologic mechanism, clinical risk, or prescribing
principle. Certain macrolides can prolong QT, especially when combined with other risks.
5. Rationale check — consider this prescribing decision: A healthy adult has uncomplicated acute bronchitis with
normal vital signs and no pneumonia findings. What is recommended? Which rationale best supports the safest
clinical decision?
A. Antibiotics are indicated for every viral respiratory illness.
B. Culture results, host factors, and resistance never influence treatment.
C. Longer and broader antibiotic therapy is always safer.
D. Routine antibiotics do not benefit uncomplicated acute bronchitis and expose patients to adverse effects and
resistance.
Correct Answer: D — Routine antibiotics do not benefit uncomplicated acute bronchitis and expose patients to
adverse effects and resistance.
Rationale: This rationale accurately identifies the relevant pharmacologic mechanism, clinical risk, or prescribing
principle. Routine antibiotics do not benefit uncomplicated acute bronchitis and expose patients to adverse effects
and resistance.
6. Rationale check — consider this prescribing decision: A patient has acute bacterial sinusitis with persistent
symptoms beyond 10 days and no penicillin allergy. Which option is often first-line? Which rationale best supports
the safest clinical decision?
A. Culture results, host factors, and resistance never influence treatment.
B. Guidelines identify amoxicillin or amoxicillin-clavulanate as first-line options when bacterial sinusitis requires
antibiotics; context and local resistance matter.
C. Antibiotics are indicated for every viral respiratory illness.
D. Longer and broader antibiotic therapy is always safer.
Correct Answer: B — Guidelines identify amoxicillin or amoxicillin-clavulanate as first-line options when bacterial
sinusitis requires antibiotics; context and local resistance matter.
Rationale: This rationale accurately identifies the relevant pharmacologic mechanism, clinical risk, or prescribing
principle. Guidelines identify amoxicillin or amoxicillin-clavulanate as first-line options when bacterial sinusitis
requires antibiotics; context and local resistance matter.
7. Rationale check — consider this prescribing decision: A patient with a perforated tympanic membrane requires
otic antibiotic drops. What is important? Which rationale best supports the safest clinical decision?
A. Administration technique, tissue exposure, and duration are irrelevant.
B. Ototoxic agents may damage the inner ear when the middle ear is exposed; select safe formulations.
C. Visual symptoms and medication adverse effects never require urgent review.
D. Topical preparations can never produce systemic adverse effects.
Correct Answer: B — Ototoxic agents may damage the inner ear when the middle ear is exposed; select safe
formulations.
Rationale: This rationale accurately identifies the relevant pharmacologic mechanism, clinical risk, or prescribing
principle. Ototoxic agents may damage the inner ear when the middle ear is exposed; select safe formulations.
8. Rationale check — consider this prescribing decision: An adult on an azole antifungal develops jaundice and dark
urine. What is the safest action? Which rationale best supports the safest clinical decision?
A. Some systemic azoles can cause hepatotoxicity; jaundice needs prompt assessment.

, INDEPENDENT STUDY RESOURCE • NURS711 • 2026–2027
B. Organ function and timing of treatment never matter.
C. Antibacterial drugs directly eliminate all viruses and fungi.
D. Systemic antiviral and antifungal medicines have no meaningful interactions.
Correct Answer: A — Some systemic azoles can cause hepatotoxicity; jaundice needs prompt assessment.
Rationale: This rationale accurately identifies the relevant pharmacologic mechanism, clinical risk, or prescribing
principle. Some systemic azoles can cause hepatotoxicity; jaundice needs prompt assessment.
9. Rationale check — consider this prescribing decision: An outpatient experiences anaphylaxis to a prescribed
antibiotic. Which practice reduces future risk? Which rationale best supports the safest clinical decision?
A. Longer and broader antibiotic therapy is always safer.
B. Accurate, specific adverse-reaction documentation supports safer future prescribing.
C. Antibiotics are indicated for every viral respiratory illness.
D. Culture results, host factors, and resistance never influence treatment.
Correct Answer: B — Accurate, specific adverse-reaction documentation supports safer future prescribing.
Rationale: This rationale accurately identifies the relevant pharmacologic mechanism, clinical risk, or prescribing
principle. Accurate, specific adverse-reaction documentation supports safer future prescribing.
10. Why should antibiotics not routinely be given for an uncomplicated viral cold?
A. They cure all viruses immediately
B. They prevent every bacterial infection
C. They always strengthen immunity
D. They do not treat viruses and unnecessary use promotes harm and resistance
Correct Answer: D — They do not treat viruses and unnecessary use promotes harm and resistance
Rationale: Antibiotics target susceptible bacteria, not viruses, and unnecessary use can cause adverse effects and
resistance.
Neuro
11. What is the priority for slow breathing and unresponsiveness after an opioid dose?
A. Provide an oral meal immediately
B. Call for emergency support and manage airway/ventilation and naloxone per protocol
C. Give additional sedatives
D. Leave the patient sleeping without monitoring
Correct Answer: B — Call for emergency support and manage airway/ventilation and naloxone per protocol
Rationale: Opioid-induced respiratory depression is potentially fatal but treatable when recognized promptly.
12. A patient on lithium has new vomiting, tremor, and unsteady gait. What should happen?
A. Take extra lithium to restore balance
B. Urgent assessment for lithium toxicity with levels and renal function
C. Ignore symptoms until routine follow-up
D. Add a thiazide without review
Correct Answer: B — Urgent assessment for lithium toxicity with levels and renal function
Rationale: Lithium has a narrow therapeutic index; neurologic and GI symptoms may signal toxicity.
