C. CSF glucose level of 25 mg/dl with a serum glucose level of 100 mg/dl

D. CSF leukocyte count of 15/mm3 with 40% polymorphonuclear cells

2. The American Academy of Pediatrics recommends that a healthy-appearing neonate born at 38 weeks’ gestation to a mother who received 8 hours of intrapartum antimicrobial prophylaxis for suspected chorioamnionitis should:


A. be observed for 48 hours.

B. undergo a full diagnostic evaluation and receive empiric therapy for a minimum of 48 hours.

3. Which of the following statements regarding the use of C-reactive protein (CRP) as a marker for neonatal sepsis is most accurate?


A. CRP levels have higher sensitivity and negative predictive values if the infant’s gestational age is at least 37 weeks.

B. CRP response is better in coagulase-negative Staphylococcus (CoNS) than gram-negative infections.

C. Serial CRP measurements may improve sensitivity and positive predictive value.

D. Sensitivity is highest when the CRP is obtained within 6 to 8 hours of the infective process.

4. Which of the following sets of hematologic values best predicts infection in a 1-hour-old term neonate?
