What is the maximum depth a heel stick should penetrate?

• A. 1.0 mm
• B. 1.5 mm
• C. 2.0 mm
• D. 2.5 mm

Answer: (C)

The correct maximum depth for a heel stick to penetrate is 2.0 mm. This guideline is crucial to prevent any potential injury to the underlying bone or tissues in infants, particularly in neonates where the heel is a common site for blood collection. Penetrating deeper than this established limit increases the risk of complications such as osteomyelitis or other infections. The recommendation to limit heel stick depth is based on the anatomy of an infant's heel, which is thinner and more delicate than that of an older child or adult. Performing a heel stick within the 2.0 mm depth range ensures that healthcare providers can collect the necessary blood sample while minimizing harm to the patient. Adhering to this guideline is important for maintaining safety and promoting best practices in pediatric phlebotomy.
