Question

Prolonged oxygen administration at a relatively high concentration in a preterm infant whose retinas are incompletely differentiated or vascularized may result in retinopathy of prematurity (ROP, retrolental fibroplasia).

a) True
b) False

Answer 1

The assertion that prolonged high-concentration oxygen therapy in preterm infants can result in retinopathy of prematurity (ROP) is true. Supplemental oxygen may be needed for prematurity due to inadequate pulmonary surfactant leading to respiratory distress syndrome (RDS). Devin is experiencing false labor indicated by Braxton Hicks contractions, and hence, advised to return home.

Step-by-step explanation:

The question regarding the prolonged oxygen administration leading to retinopathy of prematurity (ROP) in preterm infants where retinas are not fully developed is true. Preterm infants may require supplemental oxygen because their lungs might not be fully developed, resulting in conditions like infant respiratory distress syndrome (RDS). In RDS, insufficient production of pulmonary surfactant makes it hard for the lungs to inflate, reducing gas exchange capabilities. Treatments often include the administration of supplemental oxygen, pulmonary surfactant, and possibly mechanical ventilation if spontaneous breathing is not adequate.

As for Devin's situation at 35 weeks of pregnancy experiencing contractions, the intact mucus plug and the undilated cervix suggest that it is not yet time for labor. Devin is experiencing Braxton Hicks contractions, which are false labor pains, and since there are no signs of active labor, returning home is advised.
