Place the newborn skin to skin on the mother's chest.Placing the newborn skin to skin on the mother's chest is an effective technique to significantly decrease the newborn's pain level and anxiety. The nurse should implement this technique before, during, and after the procedure.A cool pack will constrict the blood vessels, making it more difficult to obtain an adequate specimen. The nurse should apply a warm pack prior to the puncture.The pain experienced from a heel stick is too brief to warrant risking the adverse effects of parenteral analgesia.A spring-loaded, automatic puncture device is recommended to minimize pain by ensuring that the depth of the puncture is not too deep, avoiding injury to the newborn.
