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?

Choice A reason: Giving 2 ounces of water before newborn genetic screening is unnecessary and inappropriate, as the test involves a heel stick blood sample, not oral intake. Water may disrupt feeding or hydration balance in newborns, making this statement incorrect and irrelevant. Choice B reason: Newborn genetic screening is typically a one-time test shortly after birth, not repeated at 2 months unless specific conditions warrant follow-up. Routine repetition is not standard, making this statement inaccurate for general teaching about the screening process. Choice C reason: Blood for newborn genetic screening is collected via a heel stick, not the inner elbow, to minimize discomfort and obtain sufficient capillary blood. Drawing from the elbow is incorrect and impractical for newborns, making this statement inaccurate. Choice D reason: Performing genetic screening after 24 hours ensures accurate detection of metabolic disorders, as newborns need time to metabolize nutrients. This timing aligns with national guidelines (e.g., AAP), making it essential and correct information for parents about the screening process.
