A. 24-28 weeks
B. 35-37 weeks
C. 30-32 weeks
D. At the first prenatal visit
Answer: B
Conceptual Explanation: Universal screening for vaginal and rectal GBS colonization is
recommended between 35 and 37 weeks of gestation to determine the need for
intrapartum antibiotic prophylaxis.
2. A 4-week-old infant presents with forceful, non-bilious, projectile vomiting immediately
after feeding. What is the most likely diagnosis?
A. Hypertrophic pyloric stenosis
,B. Gastroesophageal reflux disease (GERD)
C. Intussusception

A. Diagnose gestational diabetes mellitus (GDM) immediately
, B. Perform a 3-hour oral glucose tolerance test (OGTT)
C. Initiate insulin therapy
D. Repeat the 1-hour GCT in two weeks
Answer: B
Conceptual Explanation: If a 1-hour GCT (50g load) is elevated (usually >130-140
mg/dL), a definitive 3-hour OGTT (100g load) is required to diagnose GDM.
5. Which antibiotic is the first-line treatment for acute otitis media in a child with no known
allergies?
A. Azithromycin
B. Amoxicillin
C. Cephalexin
D. Ciprofloxacin
Answer: B
