Which of the following is an appropriate technique for specimen collection?

Rationale

Performing a finger stick on a toddler patient.

Finger sticks are appropriate for toddlers, as they allow for effective blood collection while minimizing discomfort. This method is also less invasive compared to other techniques, making it suitable for young children who may not tolerate larger needles.

A (Performing a heel stick on a 5-year-old patient) YOUR ANSWER

Heel sticks are typically used for infants, particularly those under 6 months of age, as their heel is less developed. By the age of 5, a child’s heel is not the ideal site for blood collection, making this technique inappropriate and potentially more painful.

B (Performing a finger stick on a toddler patient) CORRECT

This is the correct choice, as finger sticks are the preferred method for blood collection in toddlers. The fingers are more developed than the heels of infants, allowing for easier access and a more comfortable experience for the child.

C (Performing a thumb stick on an infant) YOUR ANSWER

Thumb sticks are not a standard practice for blood collection in infants due to the underdevelopment of thumb pads and potential difficulty in obtaining a sufficient blood sample. Heel sticks are the recommended method for infants instead.

D (Performing a thumb stick on a 5-year-old patient) YOUR ANSWER

Similar to heel sticks, thumb sticks are not commonly used as they are not an effective method for blood collection in children who are older than infants. The fingers provide a better site for the procedure, making this choice inappropriate.

Conclusion

In pediatric blood collection, selecting the appropriate technique is crucial for minimizing discomfort and ensuring a successful sample. Performing a finger stick on a toddler is the most suitable method, as it balances efficacy and patient comfort. Alternatives such as heel or thumb sticks are either outdated or inappropriate for older children, emphasizing the importance of age-appropriate collection methods in clinical practice.
