Which of the following is a phlebotomist required to document on a CBC specimen label?
Patient's insurance provider name
Phlebotomist's full name
Phlebotomist's certification number
Patient's identification number
The Correct Answer is D
Choice A reason:
The patient's insurance provider name is not typically required on a CBC specimen label. While insurance information is crucial for billing purposes, it does not serve as an identifier for the specimen itself and is therefore not documented on the label.
Choice B reason:
The phlebotomist's full name is not a requirement for a CBC specimen label. The focus of documentation on the label is on patient identification and specimen integrity, not the identity of the healthcare professional collecting the specimen.
Choice C reason:
A phlebotomist's certification number is also not required on a CBC specimen label. While the phlebotomist's credentials are important for their professional status, they are not part of the necessary documentation for a specimen label.
Choice D reason:
The patient's identification number is a critical piece of information that must be documented on a CBC specimen label. This unique identifier links the specimen to the patient's medical record, ensuring that the test results are accurately recorded in the patient's health history.

Correct Answer is A
Explanation
Choice A reason:
The lateral section of the plantar heel is the recommended site for capillary blood collection in infants, particularly those under 6 months of age. This area is preferred because it is sufficiently vascularized for blood collection and poses less risk of injury to bones and nerves compared to other areas.
Choice B reason:
The central area of the heel is not recommended for capillary blood collection in infants due to the higher risk of injury to the calcaneus (heel bone) and potential for calcaneal osteomyelitis, an infection of the bone.
Choice C reason:
The posterior curvature of the heel is also not an appropriate site for capillary blood collection in infants. This area has a higher likelihood of causing pain and injury, as well as being less accessible for a proper puncture technique.
Choice D reason:
The palmer surface of the distal phalanx (fingertip) is not a recommended site for capillary blood collection in infants under 1 year of age. The fingertips of infants are small and more prone to injury, and the procedure may be more painful compared to a heel stick.
Correct Answer is A
Explanation
Choice A Reason:
The recommended heel stick depth of 2.0 mm is based on the need to minimize the risk of injury to the infant. Penetrating deeper than this can increase the likelihood of hitting bone, which in infants can be as close as 2.0 mm under the skin of the plantar surface of the heel. This depth is sufficient to obtain a blood sample without risking injury to deeper tissues or bone.
Choice B Reason:
A depth of 2.5 mm may be too deep for some infants, especially preterm or very small infants, where the calcaneus (heel bone) is closer to the surface. While this depth might still be safe for some infants, it does not provide the same margin of safety as the 2.0 mm recommendation and could potentially lead to bone puncture or other injuries.
Choice C Reason:
A depth of 3.0 mm significantly increases the risk of bone puncture, especially in infants with less subcutaneous fat or in those who are preterm. This depth could easily breach the protective layer of skin and subcutaneous tissue, leading to a higher risk of osteomyelitis, an infection of the bone, which can be a serious complication in infants.
Choice D Reason:
A depth of 3.5 mm is considered too deep for a heel stick procedure and is likely to cause injury to the infant. This depth would almost certainly penetrate the bone in most infants, leading to severe pain, potential for infection, and other complications. It is well beyond the safe range recommended by CLSI and should be avoided.
