What action should a nurse take before performing a heel stick on a newborn?

Applying a heat pack 5 to 10 minutes prior to a heel stick on a newborn is an effective strategy for improving the procedure. The warmth from the heat pack promotes better blood flow to the area, which can help to make the blood collection easier and less painful for the infant. Increased blood flow means that the capillaries are more engorged, allowing for a more efficient heel stick and reducing the chances of complications or the need for multiple attempts.

This action not only facilitates the technical aspect of the procedure but also contributes to the comfort of the newborn. In pediatric care, it's crucial to minimize discomfort and stress for both the infant and the parents, and effective techniques, like warming the area, play an essential role in achieving this.
