The nurse is preparing to collect a neonatal screening test from the neonate, and performs which of the following prior to puncturing the heel in order to increase blood flow?
1. Feed the infant.
2. Position the infant with the foot of the bed elevated.
3. Apply a warm compress to the foot to be punctured.
4. Elevate the foot for 5-10 minutes before puncturing.
3
Rationale: Applying a warm compress will improve blood flow to the foot and help to improve blood flow after performing the puncture. If the infant is fed prior to collecting the specimen, vomiting is almost assured, as the infant will cry vigorously. Elevating the foot of the bed or just the foot of the infant will diminish blood flow because gravity will reduce circulating blood.
