A nurse is preparing to perform a heel stick on an infant. Which of the following actions should the nurse plan to take to reduce the infant's pain during the procedure?

A. Apply a cool cloth to the infant's heel 5 min prior to the procedure: Cooling the skin can cause vasoconstriction, making the heel stick more difficult and potentially increasing discomfort. This intervention does not support pain reduction and may prolong the procedure, which can further distress the infant. B. Promote skin-to-skin contact with the infant's guardian during the procedure: Skin-to-skin contact is an evidence-based method that reduces procedural pain in infants by stabilizing heart rate, enhancing comfort, and lowering stress responses. It offers both analgesic and calming effects, making it an effective strategy during heel sticks. C. Provide the infant with a bottle of water during the procedure: Water does not provide analgesic benefit to infants and does not activate soothing mechanisms such as the sucrose-induced endorphin release used for pain relief. Offering plain water may also be inappropriate for young infants due to risk of water intoxication. D. Apply lidocaine/prilocaine cream 15 min prior to the procedure: This topical anesthetic requires significantly longer, typically 30 to 60 minutes, to achieve adequate analgesic effect. Applying it only 15 minutes before the heel stick would not provide sufficient pain control, limiting its effectiveness.
