Section 1: Antibiotics & Infectious Disease (Questions 1–15)
Question 1
A 28-year-old non-pregnant woman has uncomplicated acute cystitis.
Which is first-line therapy?
A) Ciprofloxacin 500 mg BID x 3 days
B) Nitrofurantoin monohydrate 100 mg BID x 5 days
C) Amoxicillin 500 mg TID x 7 days
D) Doxycycline 100 mg BID x 7 days
Correct ,,answer,,,,: B
,Rationale: IDSA guidelines recommend nitrofurantoin, TMP-SMX (if
local resistance <20%), or fosfomycin for uncomplicated cystitis.
Fluoroquinolones (ciprofloxacin) are reserved for complicated cases due
to resistance and side effects. Amoxicillin has high E. coli resistance.
Doxycycline is not for cystitis.
Question 2
A 45-year-old with penicillin allergy (anaphylaxis) has strep throat.
Which is safest?
A) Amoxicillin
B) Cephalexin
C) Azithromycin
D) Clindamycin
Correct ,,answer,,,,: C
Rationale: For severe penicillin allergy (anaphylaxis), avoid
cephalosporins (cross-reaction risk ~1-2% but caution). Macrolides
(azithromycin) or clindamycin are alternatives. Azithromycin is
preferred for GAS pharyngitis.
Question 3
A 70-year-old with COPD and community-acquired pneumonia (CAP)
has comorbidities. Which outpatient regimen is appropriate?
A) Amoxicillin alone
,B) Doxycycline alone
C) Amoxicillin-clavulanate + azithromycin
D) Levofloxacin alone
Correct ,,answer,,,,: D
Rationale: In COPD/comorbidities, IDSA/ATS guidelines recommend
respiratory fluoroquinolone (levofloxacin, moxifloxacin) or beta-lactam
+ macrolide. Monotherapy with levofloxacin is acceptable for outpatient
CAP without Pseudomonas risk.
Question 4
A 25-year-old man has rectal gonorrhea. Which is recommended?
A) Ceftriaxone 500 mg IM once + azithromycin 1 g PO once
B) Cefixime 400 mg PO once
C) Doxycycline 100 mg BID x 7 days
D) Levofloxacin 500 mg daily x 7 days
Correct ,,answer,,,,: A
Rationale: CDC 2021 STI guidelines: ceftriaxone 500 mg IM (1 g if
>150 kg) plus azithromycin 1 g PO for uncomplicated gonorrhea (any
site). Cefixime is less effective for pharyngeal/rectal. Doxycycline is for
chlamydia co-treatment.
Question 5
, Which antibiotic causes gray-brown discoloration of teeth in children <8
years?
A) Amoxicillin
B) Cefdinir
C) Tetracycline
D) Azithromycin
Correct ,,answer,,,,: C
Rationale: Tetracyclines (including doxycycline) chelate calcium in
developing teeth, causing permanent staining. Avoid in pregnancy and
children <8 unless no alternative (e.g., doxycycline for Rocky Mountain
spotted fever).
Question 6
A patient on warfarin starts TMP-SMX for a UTI. What is the risk?
A) Decreased INR (clot risk)
B) Increased INR (bleeding risk)
C) No interaction
D) Increased risk of QTc prolongation
Correct ,,answer,,,,: B
Rationale: TMP-SMX inhibits CYP2C9 (metabolizes warfarin) and
displaces warfarin from protein binding, significantly increasing INR.
Monitor INR closely; reduce warfarin dose.
