100% CORRECT ANSWERS | CHAMBERLAIN
COLLEGE | GRADE A PACK
1. What is the primary goal of antibiotic therapy for community-acquired pneumonia
(CAP)?
A. Eradicate all bacteria in the respiratory tract
B. Return to baseline respiratory status
C. Prevent antibiotic resistance
D. Reduce fever within 24 hours
Correct Answer: B
Rationale: The primary goal of antibiotic therapy for CAP is to return the patient to their
baseline respiratory status, resolving symptoms such as fever and leukocytosis within a
few days. Eradicating all bacteria is not feasible, and while preventing resistance is
important, it is not the primary goal.
2. Which antibiotic is the first-line treatment for previously healthy adults with CAP?
A. Levofloxacin
B. Amoxicillin
C. Ceftriaxone
D. Vancomycin
Correct Answer: B
Rationale: Amoxicillin is the first-line treatment for previously healthy adults with CAP
due to its efficacy against Streptococcus pneumoniae, the most common pathogen.
Levofloxacin is used for resistant cases or recent antibiotic exposure.
3. What is the mechanism of action of antihistamines in treating allergic rhinitis?
A. Prevent release of inflammatory mediators
B. Block histamine-1 receptors
C. Activate vascular alpha-1 receptors
D. Stimulate respiratory secretions
Correct Answer: B
Rationale: Antihistamines block histamine-1 receptors, reducing symptoms like sneezing
and itching caused by histamine release in allergic rhinitis.
4. Which pathogen is most commonly associated with CAP in patients with cystic
fibrosis?
A. Streptococcus pneumoniae
B. Pseudomonas aeruginosa
C. Mycoplasma pneumoniae
D. Haemophilus influenzae
, Correct Answer: B
Rationale: Pseudomonas aeruginosa is a common cause of CAP in patients with cystic
fibrosis due to their chronic lung disease and susceptibility to opportunistic infections.
5. What is the first-line treatment for chlamydial pneumonia in infants?
A. Amoxicillin
B. Erythromycin
C. Levofloxacin
D. Ceftriaxone
Correct Answer: B
Rationale: Erythromycin is the standard treatment for chlamydial pneumonia in infants,
typically dosed at 50 mg/kg/day for 14 days.
6. What is a common side effect of benzoyl peroxide when used for acne treatment?
A. Hyperpigmentation
B. Skin dryness and peeling
C. Systemic hypotension
D. Seizures
Correct Answer: B
Rationale: Benzoyl peroxide commonly causes skin dryness, slight burning, and peeling.
Severe irritation like blistering requires dosage adjustment or discontinuation.
7. Which medication is contraindicated in patients with asthma due to potential
hypersensitivity reactions?
A. Guaifenesin
B. Benzoyl peroxide
C. Cromolyn
D. Azithromycin
Correct Answer: B
Rationale: Benzoyl peroxide can cause severe hypersensitivity reactions, particularly in
patients with asthma, and should be used cautiously.
8. What is the mechanism of action of cromolyn in treating allergic conditions?
A. Blocks histamine-1 receptors
B. Prevents release of inflammatory mediators
C. Activates alpha-1 receptors
D. Inhibits bacterial cell wall synthesis
Correct Answer: B
Rationale: Cromolyn prevents the release of inflammatory mediators from mast cells,
reducing allergic responses.
9. Which drug class is the first-line treatment for mild to moderate acne?
A. Oral antibiotics
B. Topical retinoids
C. Systemic corticosteroids
D. Antihistamines
Correct Answer: B
Rationale: Topical retinoids, often combined with topical antibiotics, are the first-line
treatment for mild to moderate acne due to their ability to normalize skin cell turnover.
10. What is the safest anticoagulant for pregnant women requiring therapy?
A. Warfarin
