1. A 25-year-old woman presents with dysuria, frequency, and no fever. Urinalysis
shows nitrites and leukocytes. What is the first-line treatment?
Answer: Trimethoprim/sulfamethoxazole (TMP/SMX) 160/800 mg BID × 3 days
Rationale: TMP/SMX is first-line for uncomplicated cystitis if local resistance <20%.
Nitrofurantoin is also first-line but requires 5 days. Fluoroquinolones are reserved for
complicated cases due to resistance and side effects.
2. A 65-year-old man with COPD presents with productive cough, fever, and chest
x-ray showing right lower lobe infiltrate. He has not taken antibiotics in the past 3
months. What is the appropriate treatment?
Answer: Amoxicillin or doxycycline
,Rationale: For CAP in outpatients without comorbidities or recent antibiotics,
amoxicillin or doxycycline is recommended. Macrolides are an alternative but resistance
is increasing.
3. A 45-year-old with recent antibiotic use presents with CAP. What is the
recommended therapy?
Answer: Respiratory fluoroquinolone (levofloxacin or moxifloxacin)
Rationale: If the patient has taken antibiotics in the past 90 days, guidelines
recommend a respiratory fluoroquinolone or beta-lactam plus macrolide to cover
resistant pathogens.
4. A child presents with cough, low-grade fever, and gradual onset of symptoms.
Chest x-ray shows interstitial infiltrates. What is the most likely pathogen and
treatment?
Answer: Mycoplasma pneumoniae; treat with macrolide (azithromycin)
Rationale: Mycoplasma causes atypical pneumonia with gradual onset. Macrolides are
first-line in children. Doxycycline is alternative but avoided in young children due to
tooth discoloration.
5. A 70-year-old nursing home resident develops watery diarrhea 7 days after
completing ceftriaxone. What is the next step?
Answer: Stop ceftriaxone, start oral vancomycin 125 mg QID × 10 days
Rationale: This is Clostridioides difficile colitis. Oral vancomycin is first-line.
Metronidazole is no longer preferred due to inferior efficacy.
6. Which antibiotic class is most strongly associated with C. difficile infection?
Answer: Second- and third-generation cephalosporins
Rationale: Broad-spectrum cephalosporins disrupt gut flora significantly, allowing C.
difficile overgrowth. Clindamycin, fluoroquinolones, and penicillins are also risks but
cephalosporins are the most common.
7. A patient taking metronidazole for bacterial vaginosis calls reporting nausea
and metallic taste. What additional warning should be reinforced?
, Answer: Avoid alcohol; can cause disulfiram reaction (flushing, nausea, vomiting)
Rationale: Metronidazole inhibits aldehyde dehydrogenase, causing acetaldehyde
accumulation if alcohol is consumed. Patients must abstain during and for 3 days after
completion.
8. A patient with HIV presents with difficulty swallowing and creamy white
plaques in the esophagus. What is the likely diagnosis and treatment?
Answer: Esophageal candidiasis; fluconazole 200 mg PO on day 1, then 100 mg daily ×
14–21 days
Rationale: Fluconazole is first-line for oropharyngeal and esophageal candidiasis. For
refractory cases, echinocandins or amphotericin B are used.
9. A patient with systemic fungal infection has a history of renal impairment.
Which antifungal requires dose adjustment and nephrotoxicity monitoring?
Answer: Amphotericin B
Rationale: Amphotericin B causes dose-dependent nephrotoxicity. Liposomal
formulations reduce but do not eliminate risk. Azoles require hepatic monitoring, not
primarily renal adjustment.
10. A patient on long-term fluconazole requires monitoring for which adverse
effect?
Answer: Hepatotoxicity
Rationale: All azole antifungals can cause elevated liver enzymes. Periodic LFT
monitoring is recommended. Fluconazole also causes QT prolongation, especially at
high doses.
11. A 28-year-old presents with painless genital ulcer and inguinal
lymphadenopathy. Darkfield microscopy shows spirochetes. What is the
treatment?
Answer: Benzathine penicillin G 2.4 million units IM once
Rationale: Primary syphilis is treated with a single dose. For neurosyphilis, aqueous
crystalline penicillin G IV × 10–14 days is required.
