The nurse places an infant with a tracheoesophageal fistula under a radiant warmer with the infant's head elevated at a 45-degree angle. Which statement by the mother indicates an understanding of the most important reason for this position?

A. Keep the newborn in a well-lit nursery: A well-lit nursery can overstimulate a preterm newborn. Preterm infants benefit more from a dim, quiet environment that mimics the womb.
B. Cluster the newborn's care activities: This helps minimize disruptions to the newborn’s rest periods, which is crucial for their growth and neurodevelopment. Clustering care reduces stress and promotes better sleep cycles.
C. Position the newborn to promote extension of muscles: Preterm infants generally benefit from a flexed position, which is more comforting and developmentally appropriate, rather than promoting muscle extension.
D. Use fingertips when calming the newborn: Using fingertips might be too stimulating for a preterm newborn. Instead, a gentle, whole-hand touch is often more comforting and less likely to cause overstimulation.

A. "Apply cold compresses when your child expresses pain." Cold can cause vasoconstriction, which may precipitate a sickle cell crisis by reducing blood flow to the extremities, thus increasing the risk of sickling of red blood cells. Warm compresses are recommended to help alleviate pain by promoting blood flow.
B. "Restrict outdoor play activity to 1 hour per day." While it's important to monitor physical activity to avoid overexertion, restricting outdoor play to a specific time frame without considering other factors like hydration and rest isn't the right approach. Physical activity is important but should be balanced with adequate hydration and rest.
C. "Monitor your child's temperature daily." While monitoring temperature is important, it isn't specifically critical on a daily basis unless there is a suspicion of infection. The primary focus should be on hydration and recognizing signs of infection.
D. "Offer fluids to your child multiple times every day." Hydration is crucial for children with sickle cell anemia as it helps to prevent sickling of cells by maintaining good blood flow and preventing dehydration, which can trigger a crisis.
