Question 1 of 5
What is the most appropriate antibiotic for treatment of her pneumonia?
Correct Answer: C
Rationale: A 10-year-old with lobar pneumonia and a history of cefaclor reaction (rash, target lesions, arthralgia) and familial penicillin anaphylaxis requires a safe antibiotic. Clindamycin (Choice C) is appropriate for community-acquired pneumonia, covering Streptococcus pneumoniae and some atypicals, and avoids beta-lactam cross-reactivity risks from her cephalosporin reaction and penicillin family history. Ceftriaxone (Choice A) and penicillin (Choice D), as beta-lactams, risk allergic reactions. Ciprofloxacin (Choice B) is less preferred in children due to side effects and atypical coverage focus. Clindamycin is the safest, effective choice.
