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 A
Explanation
Choice A rationale
Closed loop communication is essential in critical situations as it ensures that information is accurately sent, received, and confirmed, reducing errors by allowing team members to verify directives and actions.
Choice B rationale
Open-ended communication methods are prone to misinterpretations and delays in critical situations, making them unsuitable for ensuring precision and immediate understanding, as required in urgent medical scenarios.
Correct Answer is D
Explanation
Choice A rationale
Infection of the uterus typically presents with fever, foul-smelling lochia, and uterine tenderness, not bright red vaginal bleeding with a firm fundus. Firm fundus decreases the likelihood of retained products causing infection.
Choice B rationale
Uterine atony causes excessive vaginal bleeding due to the uterus's inability to contract effectively, but it doesn't apply here since the fundus is firm, indicating adequate uterine tone.
Choice C rationale
Perineal hematoma results from blood vessel damage during delivery. It causes a tense, painful mass and vaginal or perineal swelling, not steady, bright red bleeding with a firm fundus.
Choice D rationale
Lacerations of the genital tract result in bright red bleeding despite a firm fundus, as the bleeding originates from tears in the vaginal or perineal tissues rather than uterine atony.
