A nurse is providing teaching to the parents of a newborn about newborn genetic screening. Which of the following statements should the nurse include in the teaching?

A. "This test should be performed after your baby is 24 hours old.": Newborn genetic screening is ideally performed after 24 hours of life to ensure accurate detection of metabolic and endocrine disorders. Performing the test too early can result in false-negative results due to insufficient accumulation of metabolites in the blood. B. "A nurse will draw blood from your baby's inner elbow.": Newborn screening is typically performed via a heel stick, not from the inner elbow. The lateral or plantar aspect of the heel provides safe access to capillary blood for accurate testing. C. "Your baby will be given 2 ounces of water to drink prior to the test.": Newborns are not given water prior to screening. Water administration is unnecessary and could be harmful, as infants should receive breast milk or formula to meet hydration needs. D. "This test will be repeated when your baby is 2 months old.": While some repeat testing may occur if initial results are inconclusive, routine newborn genetic screening is performed once after 24 hours of life, not automatically repeated at 2 months.
