While caring for a preterm newborn receiving oxygen therapy, the nurse monitors the oxygen level and duration closely based on the understanding that the newborn is at risk for which of the following?
A) Retinopathy of prematurity
B) Metabolic acidosis
C) Infection
D) Cold stress
A
Response:
Oxygen therapy has been implicated in the pathogenesis of retinopathy of prematurity (ROP). Therefore, the nurse monitors the newborn's oxygen therapy closely. Metabolic acidosis may occur due to anaerobic metabolism used for heat production. Infection may occur for numerous reasons, but they are unrelated to oxygen therapy. Cold stress results from problems due to the preterm newborn's inadequate supply of brown fat, decreased muscle tone, and large body surface area.
