51. A phlebotomist should recognize that the Clinical and Laboratory Standards Institute (CLSI) recommends that a heel stick depth should not penetrate deeper than which of the following depths for an infant patient?
Answer: A
The heel stick depth for an infant patient should not penetrate deeper than 2.0 mm.
For infant patients, the Clinical and Laboratory Standards Institute (CLSI) recommends that heel stick depth should not exceed 2.0 mm to prevent complications and ensure patient safety.
A) 2.0 mm
This option is correct as it aligns with the CLSI guidelines that specify the maximum depth for a heel stick in infants should be 2.0 mm. This recommendation is crucial to avoid damaging deeper tissues and ensuring safe blood collection practices.
B) 2.5 mm
Option B is incorrect because a heel stick depth of 2.5 mm exceeds the recommended limit set by CLSI. Penetrating deeper than 2.0 mm increases the risk of injury to the infant's heel and can lead to complications such as infection or damage to underlying structures.
C) 3.0 mm
This option is also incorrect, as a depth of 3.0 mm far exceeds the CLSI recommendation. Such depth poses a significant risk of injury and is not considered safe for infant patients during blood collection procedures.
D) 3.5 mm
Option D is incorrect as it suggests an even greater depth of penetration, which is not permissible according to CLSI guidelines. A heel stick depth of 3.5 mm would likely cause harm to the infant and should be avoided in clinical practice.
Conclusion
The correct answer, 2.0 mm, is based on established safety guidelines from CLSI that aim to protect infant patients during blood collection. All other options exceed this safe limit, highlighting the importance of adhering to recommended practices to prevent potential harm.
