A nurse is preparing to perform a dressing change on a preschooler. Which of the following actions should the nurse take to prepare the child for the procedure?

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.

Choice A reason: Amniocentesis involves needle insertion through the uterine wall, which can irritate the uterus and trigger contractions, risking preterm labor at 33 weeks. Monitoring contractions is vital to detect early labor signs, enabling interventions like tocolytics to delay delivery. This protects the premature fetus, ensuring better outcomes by maintaining pregnancy until closer to term.
Choice B reason: Vomiting is not a typical amniocentesis complication. The procedure is localized to the uterus, with minimal systemic effects. Nausea may occur from anxiety, but vomiting is rare and not a priority for monitoring. Focus remains on uterine and fetal complications, like contractions or fluid leakage, which directly impact pregnancy safety and outcomes.
Choice C reason: Hypertension is not directly linked to amniocentesis. The procedure does not typically affect maternal cardiovascular function, as it’s a localized intervention. Monitoring for hypertension is more relevant for conditions like preeclampsia. Post-amniocentesis, the priority is uterine activity and fetal distress, not blood pressure, making this an irrelevant complication to monitor.
Choice D reason: Polyuria is not associated with amniocentesis, as the procedure does not impact renal function or fluid balance. The focus is on complications like contractions, bleeding, or amniotic fluid leakage, which pose direct risks to the pregnancy. Monitoring polyuria is unnecessary, as it does not reflect the procedure’s physiological effects or risks.
