Question 62

Nondominant third finger is the appropriate site for dermal specimen collection on a toddler.

Using the nondominant third finger is ideal for dermal specimen collection on a toddler due to its accessibility and the ability to minimize discomfort while obtaining the sample.

A) Nondominant dorsal hand

The nondominant dorsal hand is not the best choice for dermal specimen collection on a toddler because it may not provide the optimal blood flow and can be more sensitive than the finger, leading to increased discomfort during the procedure.

B) Dominant lateral plantar heel

The dominant lateral plantar heel is generally avoided for dermal specimen collection in toddlers as it is a more sensitive area and can cause distress to the child. Additionally, heel sticks are more commonly used for infants rather than toddlers.

C) Nondominant third finger

The nondominant third finger is the most suitable site for dermal specimen collection on a toddler. This location allows for easier access to capillaries, resulting in a more efficient blood collection while minimizing discomfort for the child.

D) Dominant antecubital space

The dominant antecubital space is typically reserved for venipuncture rather than dermal collection, making it an inappropriate choice for toddlers. This area can also be more challenging to access due to anatomical factors, and using it may result in unnecessary stress for the child.

Conclusion

The nondominant third finger is the correct choice for dermal specimen collection in toddlers due to its accessibility and lower sensitivity compared to other options. The other choices either involve areas that are too sensitive, inappropriate for this type of collection, or not commonly used in this age group, reinforcing the superiority of Option C.
