A nurse is assisting in the care of a client who is scheduled for a cesarean birth based on the fetal lungs having reached maturity. Which of the following findings indicates that the fetal lungs are mature?

Choice A rationale: Placing elbow restraints is not a recommended practice for preterm newborns. Restraints are used in some cases to prevent the baby from pulling on tubes or lines, but it is not primarily for energy conservation.
Choice B rationale: While frequent position changes are important to prevent pressure ulcers and promote comfort, they may not necessarily help conserve energy in a preterm newborn.
Choice C rationale: Preterm newborns have limited energy reserves, and conserving energy is essential for their growth and development. Clustering care activities involves combining nursing care tasks to allow for longer periods of uninterrupted rest for the baby. This approach reduces the baby's energy expenditure and promotes better weight gain and stability.
Choice D rationale: While gentle touch and massage can be beneficial for preterm newborns to promote bonding and relaxation, it may not directly conserve energy as cluster care does.

Choice A rationale: Placing the infant in a prone position (lying face down) after feeding is not recommended for a baby with gastroesophageal reflux. The prone position can increase the risk of choking and is not helpful in managing reflux.
Choice B rationale: For an infant with gastroesophageal reflux, placing the baby in an upright position after feeding can help prevent or reduce reflux episodes. Keeping the infant in an upright position allows gravity to assist in keeping stomach contents down and reduces the likelihood of reflux into the esophagus.
Choice C rationale: Placing the infant on the right side after feeding is also not recommended for managing gastroesophageal reflux. The right-side position may not be as effective in preventing reflux as the upright position.
Choice D rationale: Placing the infant on the left side after feeding is not the preferred position for managing gastroesophageal reflux. The left-side position may not be as effective in preventing reflux as the upright position.
