During a significant postpartum hemorrhage, the physician orders the nurse to administer 1000 mcg Misoprostol per rectum STAT. The nurse has on hand Misoprostol 200 mcg tablets. How many tablets should the nurse administer?

Choice A rationale

Preterm infants lack coordination for sucking, swallowing, and breathing until approximately 32-34 weeks' gestation. Gavage feeding prevents aspiration by bypassing the immature oral motor mechanisms required for safe oral feeding.

Choice B rationale

Preterm infants can digest milk due to functional gastrointestinal enzymes. Digestive immaturity relates more to delayed gastric emptying rather than the inability to process nutrients, which is managed with small frequent feeds.

Choice C rationale

Monitoring intake is crucial for growth and hydration, but gavage feeding primarily addresses feeding immaturity, not intake measurement. Accurate intake can be monitored through oral feeds with supplemental measurements.

Choice D rationale

Gavage feeding does not directly prevent thrush. Thrush prevention involves oral hygiene and immune support rather than feeding methods, as thrush may still occur regardless of tube feeding or oral intake.

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.
