Which finger is used for a capillary stick for a child older than 12 months?

1. Index finger

2. Little finger

3. Ring or middle finger on non-dominant hand

4. Thumb

The correct answer is: Ring or middle finger on non-dominant hand

For a capillary stick in a child older than 12 months, using the ring or middle finger on the non-dominant hand is the most appropriate choice. These fingers have sufficient blood supply and are less prone to injury compared to other fingers. They also provide a good surface area for obtaining a blood sample effectively while minimizing discomfort for the child. Utilizing the non-dominant hand helps prevent movement during the procedure, allowing for a steadier hand, which can lead to a more successful sample collection. This approach balances the need for accessibility, comfort, and safety during the process.
