SECTION 1: PHARMACOTHERAPY FOR BACTERIAL INFECTIONS
1. A patient presents with community-acquired pneumonia (CAP).
What is the most common bacterial pathogen?
A) Haemophilus influenzae
B) Mycoplasma pneumoniae
C) Streptococcus pneumoniae
D) Pseudomonas aeruginosa
Answer: C
Rationale: Streptococcus pneumoniae is the most common bacterial
pathogen causing community-acquired pneumonia in the general
population. Other pathogens include Haemophilus influenzae
,(common in smokers/COPD patients) and Mycoplasma pneumoniae
(atypical pneumonia, common in children).
2. What is the first-line treatment for CAP in a previously healthy
adult?
A) Ciprofloxacin
B) Amoxicillin, Doxycycline, or Macrolide (Azithromycin)
C) Vancomycin
D) Amoxicillin-clavulanate
Answer: B
Rationale: First-line treatment for CAP in previously healthy adults
includes amoxicillin, doxycycline, or macrolides such as
azithromycin. Macrolides are commonly used due to their coverage
of atypical pathogens like Mycoplasma pneumoniae.
3. A patient with CAP was treated with a macrolide but did not
improve. What is the appropriate second-line treatment?
A) Penicillin
B) Respiratory fluoroquinolone (e.g., Levofloxacin)
C) Cephalexin
D) Tetracycline
Answer: B
,Rationale: If a patient does not respond to first-line CAP treatment, a
respiratory fluoroquinolone such as levofloxacin should be
considered, especially if the patient has not received antibiotics in
the previous 90 days.
4. Which antibiotic class is associated with QT prolongation?
A) Penicillins and Cephalosporins
B) Fluoroquinolones and Macrolides
C) Aminoglycosides and Tetracyclines
D) Sulfonamides and Carbapenems
Answer: B
Rationale: Both fluoroquinolones and macrolides are associated with
QT prolongation, which can increase the risk of torsades de pointes.
Caution is required when prescribing these drugs to patients with
preexisting QT interval prolongation or those taking other QT-
prolonging medications.
5. A child is diagnosed with Mycoplasma pneumoniae pneumonia.
What is the appropriate treatment?
A) Amoxicillin
B) Macrolides (Azithromycin, Erythromycin, Clarithromycin)
C) Ciprofloxacin
D) Doxycycline
, Answer: B
Rationale: Mycoplasma pneumoniae causes atypical pneumonia
commonly seen in children and is treated with macrolides such as
azithromycin, erythromycin, or clarithromycin. If macrolide
treatment fails, a respiratory fluoroquinolone may be considered.
6. What is the treatment for community-acquired pneumonia in a
pregnant patient?
A) Ciprofloxacin
B) Amoxicillin, cephalosporins, or erythromycin
C) Doxycycline
D) Levofloxacin
Answer: B
Rationale: In pregnant patients with CAP, amoxicillin,
cephalosporins, or erythromycin are considered safe treatment
options. Fluoroquinolones and tetracyclines are generally avoided
during pregnancy due to safety concerns.
7. If a patient has been treated with an antibiotic in the previous 90
days and develops CAP, which antibiotic class is a prudent choice?
A) Penicillins
B) Macrolides
