Question 91

Dominant lateral plantar heel is the appropriate site for dermal specimen collection on a toddler.

The dominant lateral plantar heel is considered the best site for dermal specimen collection on a toddler due to its accessibility and lower risk of complications compared to other sites.

A) Nondominant dorsal hand

The nondominant dorsal hand is not the most appropriate site for dermal specimen collection in toddlers. This area can be more sensitive and may lead to discomfort or difficulty in obtaining a proper sample due to the smaller size and more variable skin thickness in this region.

B) Dominant lateral plantar heel

The dominant lateral plantar heel is indeed the most suitable site for dermal specimen collection on a toddler. This site allows for easier access to the dermal layer, minimizes pain, and reduces the risk of hitting bone or other sensitive structures, making it a preferred choice in pediatric practice.

C) Nondominant third finger

The nondominant third finger is not ideal for dermal specimen collection because the fingers are generally more mobile and sensitive, which can complicate the process and increase the likelihood of movement during the collection, potentially affecting the quality of the specimen.

D) Dominant antecubital space

The dominant antecubital space is typically used for venipuncture rather than dermal specimen collection. This area may pose a higher risk of complications, including hitting larger veins or arteries, and is not as suitable for the intended purpose in toddlers.

Conclusion

In summary, the dominant lateral plantar heel stands out as the appropriate site for dermal specimen collection in toddlers, as it offers advantages in terms of accessibility and reduced discomfort. The other options, while they may be used for different purposes, do not provide the same level of efficacy and safety for dermal procedures in this age group.
