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 D
Explanation
Choice A rationale
A soft uterus indicates uterine atony, a complication rather than a normal finding. Daily fundal palpation ensures involution but should result in a firm, not soft, uterus.
Choice B rationale
Passage of clots is common postpartum, but ongoing monitoring for excessive clotting is crucial as it may indicate retained placental fragments or incomplete uterine involution.
Choice C rationale
Decreased lochia does not indicate complications unless it is completely absent, which may suggest uterine or cervical obstruction and warrants further evaluation.
Choice D rationale
Increased lochia or bright red bleeding signifies secondary postpartum hemorrhage, often caused by retained placental tissue or subinvolution, requiring immediate medical attention.
Correct Answer is A
Explanation
Choice A rationale
Surfactant reduces alveolar surface tension, improving lung compliance and facilitating gas exchange of oxygen and carbon dioxide, critical in addressing respiratory distress syndrome in premature infants.
Choice B rationale
Periodic apnea in premature infants is a neurological immaturity issue, not directly addressed by surfactant, which targets alveolar function in the lungs.
Choice C rationale
Surfactant does not possess antimicrobial properties; it functions to stabilize alveoli, not to combat respiratory infections.
Choice D rationale
Sedation requirements for infants are unrelated to surfactant therapy, which works mechanically in the lungs rather than through central nervous system effects.
