Answer to Question 1

ANS: D
Because glucose is necessary to produce heat, the infant who is also hypoglycemic will not be able to produce enough body heat. A hematocrit level of 58 is within the expected range for newborns. WBC count may be as high as 30,000 cells/mm3. RBC count ranges from 3.9 to 5.5 million/mL.

Answer to Question 2

ANS: B
ROP is thought to occur as a result of high levels of oxygen in the blood. NEC is due to the interference of blood supply to the intestinal mucosa. Necrotic lesions occur at that site. IVH is caused by rupture of the fragile blood vessels in the ventricles of the brain. It is most often associated with hypoxic injury, increased blood pressure, and fluctuating cerebral blood flow. BPD is caused by the use of positive-pressure ventilation against the immature lung tissue.
