Correct Answer is ["A"]
Explanation
Step 1 is 33 lb × (1 kg ÷ 2.2 lb) = 15 kg.
Step 2 is 30 mg/kg/day × 15 kg = 450 mg/day.
Step 3 is 450 mg/day ÷ 2 = 225 mg per dose.
Step 4 is 225 mg ÷ (200 mg/5 mL) = 5.625 mL. The final calculated answer is 5.6 mL.
Correct Answer is C
Explanation
Choice A rationale
An APGAR score of 5 indicates significant distress and poor adjustment to extrauterine life, which is not consistent with the provided description of the infant's condition.
Choice B rationale
An APGAR score of 6 suggests moderate difficulty with extrauterine adaptation, which is still not entirely consistent with the overall assessment of the infant.
Choice C rationale
An APGAR score of 7 aligns with the described observations of the newborn: pink trunk and head, bluish extremities, active movement, heart rate of 130/min, and a response to
suctioning, which suggest the infant is in reasonably good condition with some minor issues that need monitoring.
Choice D rationale
An APGAR score of 8 would indicate that the newborn is in very good condition with only slight adjustments needed, which does not fully match the infant's description with the noted
issues like a weak cry and bluish extremities.
