Final answer:
The heel stick is a blood puncture procedure used on infants typically for newborn screening tests, performed on the lateral or medial portions of the plantar surface of the foot.
Step-by-step explanation:
The term “Heel Stick” refers to a method used for blood punctures on infants less than 1-2 years of age. The areas recommended for this procedure are the lateral or medial portions of the plantar surface of the foot.
This technique is often used for newborn screening tests, where a small amount of blood is collected for the analysis of metabolic and genetic disorders. When performing a heel stick, it is important to use the correct technique and location to minimize discomfort and reduce the risk of injury to the infant.
