CASE STUDY 1: Community-Acquired Pneumonia
Patient Profile: Emma R., 34-year-old female, previously healthy, presents with fever 101.8°F,
productive cough with rust-colored sputum, pleuritic chest pain, and tachypnea (RR 24). Chest
X-ray confirms right lower lobe infiltrate. No antibiotic use in past 90 days. Not pregnant.

Question 1
The nurse practitioner is preparing to prescribe first-line empiric therapy for this previously
healthy adult with community-acquired pneumonia (CAP). Which antibiotic regimen is MOST
appropriate?
A. Levofloxacin 750 mg PO daily
B. Amoxicillin 1 g PO three times daily
C. Azithromycin 500 mg PO on day 1, then 250 mg daily
D. Doxycycline 100 mg PO twice daily
Correct Answers: B. Amoxicillin 1 g PO three times daily
Expert Rationale: According to NR 566 exam content, first-line treatment for CAP in previously
healthy adults includes amoxicillin, doxycycline, or macrolides (azithromycin). While options B,
C, and D are all acceptable first-line agents, amoxicillin is the preferred choice for typical
bacterial pneumonia (especially with Streptococcus pneumoniae as the most common
pathogen) due to narrow spectrum, excellent lung penetration, and safety profile. Levofloxacin
(Option A) is a fluoroquinolone reserved as second-line therapy when first-line agents fail or in
patients with comorbidities/recent antibiotic use. The exam specifically emphasizes reserving
fluoroquinolones ("floxacin" drugs) for second-line use to prevent resistance. Amoxicillin
provides targeted coverage against the most likely pathogen without unnecessarily broad
spectrum.
Question 2
, Three days after initiating first-line therapy, Emma reports no improvement in symptoms and
remains febrile. Sputum culture reveals macrolide-resistant Streptococcus pneumoniae. What is
the MOST appropriate next step in management?
A. Add azithromycin to current regimen
B. Switch to levofloxacin 750 mg PO daily
C. Increase amoxicillin dose to 1.5 g PO TID
D. Add clavulanate to amoxicillin
Correct Answers: B. Switch to levofloxacin 750 mg PO daily
Expert Rationale: Per NR 566 content, when first-line therapy fails, the second choice is
levofloxacin (fluoroquinolone). The exam explicitly states: "1st line: Amoxicillin, doxycycline and
macrolide (Azithromycin); Second choice: Levaquin (Fluoroquinolones)." Since the pathogen is
macrolide-resistant and the patient failed first-line amoxicillin therapy, switching to a
fluoroquinolone provides broader Gram-positive coverage including resistant organisms. Adding
azithromycin (Option A) would be ineffective against a macrolide-resistant organism. Increasing
amoxicillin dose (Option C) or adding clavulanate (Option D) does not address macrolide
resistance. The exam emphasizes recognizing when to escalate to fluoroquinolones: "If
someone has been treated w/an antibiotic in the previous 90 days of contracting CAP, a
quinolone would be prudent choice to prescribe."
CASE STUDY 2: Pediatric Atypical Pneumonia
Patient Profile: Lucas M., 7-year-old male, presents with low-grade fever, dry hacking cough,
headache, and malaise for 5 days. Chest X-ray shows diffuse interstitial infiltrates. PCR confirms
Mycoplasma pneumoniae. Weight: 22 kg. No drug allergies.
