79. 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
A heel stick depth should not penetrate deeper than 2.0 mm for an infant patient.
For infant patients, the Clinical and Laboratory Standards Institute (CLSI) recommends that the heel stick depth should not exceed 2.0 mm to minimize the risk of injury to the bone and surrounding tissues.
A) 2.0 mm
This option is correct as it aligns with the CLSI recommendation for heel stick procedures in infants. Ensuring that the depth of the puncture does not exceed 2.0 mm is critical to avoid complications such as osteomyelitis or damage to nerves and blood vessels.
B) 2.5 mm
This option is incorrect because it exceeds the recommended depth of 2.0 mm. Penetrating deeper than this limit increases the risk of injury to the bone, which is particularly concerning in infants whose anatomy is more delicate.
C) 3.0 mm
This option is also incorrect for the same reasons as option B. A heel stick depth of 3.0 mm poses a significant risk of damaging underlying structures, which is contrary to the guidelines set by CLSI for safe blood collection in infants.
D) 3.5 mm
This option is incorrect as well, as it greatly exceeds the recommended maximum depth of 2.0 mm. Such a depth significantly raises the potential for serious complications and is not in accordance with established clinical standards.
Conclusion
The correct answer of 2.0 mm is crucial for ensuring the safety of infant patients during heel stick procedures. All other options exceed this safe depth and therefore pose a higher risk of complications, highlighting the importance of adhering to CLSI guidelines in phlebotomy practices.
