64. A phlebotomist should recognize that the Clinical and Laboratory Standards Institute (CLSI) recommends that a heel stick depth should not penetrate deeper than whic following depths for an infant patient?
Answer: A
The heel stick depth for an infant patient should not exceed 2.0 mm according to CLSI recommendations.
To ensure the safety of infant patients during blood collection, CLSI guidelines specify that a heel stick should not penetrate deeper than 2.0 mm.
A) 2.0 mm
This option is correct as it aligns with the Clinical and Laboratory Standards Institute (CLSI) recommendations. The guidelines clearly state that heel stick depth should be limited to 2.0 mm to avoid potential injury to the infant's bones and nerves.
B) 2.5 mm
Option B is incorrect because it exceeds the recommended depth limit set by CLSI. A depth of 2.5 mm poses a risk of injury and complications, which is why the guideline explicitly restricts the depth to 2.0 mm.
C) 3.0 mm
This option is also incorrect as it significantly exceeds the maximum safe depth. A heel stick of 3.0 mm could lead to serious complications for the infant, including damage to underlying structures.
D) 3.5 mm
Option D is incorrect as it far exceeds the recommended depth limit. Penetrating to 3.5 mm can result in severe risks, including bone injury and nerve damage, contrary to the safety measures outlined by CLSI.
Conclusion
The correct answer is 2.0 mm, as this adheres to the CLSI recommendations designed to protect infant patients during blood collection procedures. All other options exceed the safe depth and could lead to potential harm, highlighting the importance of following established guidelines in clinical practice.
