A premature infant is on oxygen therapy. Due to oxygen therapy, the nurse explains to the parents that their infant is at a higher risk for:
Visual impairment.
Sensitivity to touch.
Hyperbilirubinemia.
Cerebral palsy.
The Correct Answer is A
Choice A rationale
Visual impairment, including retinopathy of prematurity, results from immature retinal vascularization and oxidative damage caused by prolonged oxygen therapy in premature infants, leading to neovascularization and potential retinal detachment.
Choice B rationale
Sensitivity to touch reflects neurologic immaturity or overstimulation in premature infants but is not directly associated with oxygen therapy. It stems from underdeveloped sensory pathways and an immature central nervous system.
Choice C rationale
Hyperbilirubinemia arises from excessive bilirubin production or impaired hepatic clearance in neonates, unrelated to oxygen therapy. Factors include hemolysis, immature liver enzyme systems, or delayed feeding initiation.
Choice D rationale
Cerebral palsy, a motor disorder due to non-progressive brain injury, can result from perinatal asphyxia or intracranial hemorrhage, but it is not a direct outcome of oxygen therapy in premature infants.

Correct Answer is B
Explanation
Choice A rationale
Tight swaddling does not address hypoglycemia but may increase the infant’s stress. Hypoglycemia requires immediate correction through feeding or IV glucose, as low glucose levels can impair neonatal neurologic function.
Choice B rationale
Feeding provides immediate glucose replenishment, correcting hypoglycemia, which manifests as trembling. Rechecking glucose ensures effective correction. Normal neonatal glucose levels are 45–65 g/dL, with intervention needed below 40 g/dL.
Choice C rationale
Monitoring urinary output is insufficient for managing neonatal hypoglycemia. Trembling indicates an acute need for glucose, requiring prompt feeding or IV glucose rather than passive observation of output.
Choice D rationale
Immediate NICU transfer is unnecessary unless hypoglycemia remains uncorrected or other complications arise. Prompt feeding and glucose recheck are adequate to stabilize the neonate in most cases.
