This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Neonatal hypothermia, Subject name: Pediatrics
A neonate weighing 1.3 kg is born at 32 weeks' gestation and was transferred to the nursery for prematurity. After 1 hr the nurse repos the infant is tachypnoeic with hea rate 150 bpm, respiratory rate 76/min, temperature 95degF and oxygen saturation of 98%. The lungs are clear with bilateral breath sounds and there is no murmur and x-ray chest is normal. Which of the following is the next step in management of the neonate? 
Select and explain. 
A. Administer intravenously 5ml of D50., B. Obtain a complete blood count and differential, C. Perform a lumbar puncture, D. Place the infant under a warmer
D: Place the infant under a warmer
Answer: D: Place the infant under a warmer 
Explanation: Clinical description s/o hypothermia in neonate. A room temperature of 24degC provides a cold environment for newborn infants. At bih, infants (especially preterm) are wet, have a relatively large surface area for their weight, and have little subcutaneous fat. Within minutes of delivery, the infants are likely to become pale or blue and their body temperature drops. A preterm infant is likely to have respiratory distress and unable to oxygenate properly, lactate can accumulate and lead to a metabolic acidosis. Infants rarely shiver in response to a need to increase heat production. Therefore, to prevent infant from hypothermia, Place the infant under a warmer. If the tachypnea persists after warming the infant, sepsis, pneumonia, and primarysurfactant deficiency are all possible.
