What location is appropriate for a blood draw from a healthy 10-month-old?

1. Venipuncture in arm

2. Heel

3. Fingerstick

4. Ear lobe

The correct answer is: Heel

For a healthy 10-month-old, the heel is the most appropriate site for a blood draw. This choice is based on several factors related to infant physiology and the minimization of discomfort and potential complications. At the age of 10 months, infants have smaller veins that can be difficult to access through standard venipuncture techniques. The heel provides a safe and effective alternative, as the blood vessels in this area are more superficial and easier to access without requiring extensive venipuncture skills. Heel sticks are specifically designed for infants as they reduce the risk of injury to the infant's more fragile vascular structures and surrounding tissue. Additionally, heel sticks are commonly used for newborn screenings and routine blood tests because they cause less stress and trauma compared to other methods. Using the heel for blood collection allows for the collection of a sufficient blood sample while keeping the procedure minimally invasive. Other methods, such as venipuncture in the arm or fingersticks, might not be suitable at this age due to developmental limitations and may also introduce more discomfort for the infant. The ear lobe is generally not recommended for blood draws in infants due to both access issues and the potential for greater pain and complications.
