Chamberlain Grade A
1. A nurse is identifying common pathogens in community-acquired pneumonia (CAP).
Which are common CAP pathogens? (Select all that apply.)
A. Streptococcus pneumoniae
B. Mycoplasma spp.
C. Haemophilus influenzae
D. Staphylococcus aureus
E. Escherichia coli
Correct Answer: A, B, C, D
Rationale: Common CAP pathogens include S. pneumoniae, Mycoplasma spp., H.
influenzae, and S. aureus. E. coli is more commonly associated with healthcare-
associated pneumonia.

2. A nurse is prescribing first-line treatment for CAP in previously healthy adults. What
are first-line options, and what is the second choice?
A. First-line: Amoxicillin, doxycycline, macrolides (azithromycin); Second choice:
Fluoroquinolones (levofloxacin)
B. First-line: Fluoroquinolones; Second choice: Amoxicillin
C. First-line: Cephalosporins; Second choice: Macrolides
D. First-line: Vancomycin; Second choice: Tetracyclines
Correct Answer: A
Rationale: First-line treatment for CAP in previously healthy adults includes amoxicillin,
doxycycline, and macrolides (azithromycin). Fluoroquinolones (levofloxacin) are used as
second-line therapy.
3. A nurse is treating a pediatric patient with Mycoplasma pneumoniae. What is the
recommended treatment?
A. Fluoroquinolones
B. Macrolides (azithromycin, erythromycin, clarithromycin)
C. Amoxicillin
D. Cephalosporins
Correct Answer: B
,3|Page
Rationale: Mycoplasma pneumoniae in pediatric patients is treated with macrolides
including azithromycin, erythromycin, and clarithromycin.
4. A pregnant patient is diagnosed with community-acquired pneumonia. Which
antibiotics are safe to prescribe? (Select all that apply.)
A. Amoxicillin
B. Cephalosporins
C. Erythromycin
D. Tetracyclines
E. Fluoroquinolones
Correct Answer: A, B, C
Rationale: During pregnancy, amoxicillin, cephalosporins, and erythromycin are
considered safe for treating CAP. Tetracyclines and fluoroquinolones are avoided due to
teratogenic risks.
5. A patient has been treated with an antibiotic in the previous 90 days and now
presents with CAP. What class of antibiotics would be a prudent choice?
A. Macrolides
B. Tetracyclines
C. Fluoroquinolones ("floxacin" drugs such as gemifloxacin, ciprofloxacin, levofloxacin)
D. Penicillins
, 4|Page
Correct Answer: C
Rationale: If a patient has received antibiotics in the previous 90 days, a
fluoroquinolone (e.g., levofloxacin, moxifloxacin) is recommended due to the risk of
resistance to other classes.
6. A nurse is treating an infant with chlamydial pneumonia. What is the recommended
treatment?
A. Azithromycin 500 mg orally on day 1 followed by 250 mg once daily on days 2-5
B. Erythromycin 12.5 mg/kg PO QID x 14 days
C. Amoxicillin 40 mg/kg/day x 10 days
D. Doxycycline 100 mg BID x 14 days
Correct Answer: B
Rationale: Chlamydial pneumonia in an infant is treated with erythromycin 12.5 mg/kg
PO four times daily for 14 days.
7. A nurse is determining when to use broad-spectrum antibiotics. In which situations
are broad-spectrum antibiotics appropriate? (Select all that apply.)
A. Before culture results are available
B. For critically ill patients
C. For empiric therapy when the pathogen is unknown or multiple types of bacteria are
suspected
