According to the Joint Commission, which of the following should a phlebotomist use as a unique identifier when establishing correct inpatient identification?
Patient's room number
Patient's bed label
Patient's inpatient chart
Patient's verbal confirmation
The Correct Answer is C
Choice A Reason:
A patient's room number is not considered a unique identifier by the Joint Commission standards. Room numbers can change if patients are moved, and they do not reliably identify an individual.
Choice B Reason:
A patient's bed label is also not a unique identifier. Bed labels can be switched, and similar to room numbers, they are not specific to the individual patient.
Choice C Reason:
A patient's inpatient chart typically contains multiple unique identifiers, such as the patient's name, an assigned identification number, date of birth, or other person-specific identifiers. These are considered acceptable by the Joint Commission for verifying patient identity, ensuring that the service or treatment is intended for that individual.
Choice D Reason:
Patient's verbal confirmation alone is not sufficient for establishing correct inpatient identification. While it can be used as one method of identification, it should be supplemented with another identifier to meet the Joint Commission's requirement of using at least two patient identifiers.

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.
Correct Answer is D
Explanation
Choice A reason:
Turning the patient's hand palm down is not typically recommended as it can make the veins less accessible and may cause discomfort to the patient. The veins on the back of the hand are more superficial and can be more easily accessed when the hand is palm up.
Choice B reason:
Placing the patient in a supine position is not necessary for all venipuncture procedures and is usually reserved for patients who have a history of fainting or for those who are already lying down due to their medical condition. It is not a position that specifically increases comfort during the procedure.
Choice C reason:
Bending the patient's arm at the elbow can actually hinder the blood draw process as it may cause the veins to be less prominent and can lead to discomfort or movement during the venipuncture, potentially causing injury or an unsuccessful draw.
Choice D reason:
Positioning the patient's hand at waist level is the correct choice as it allows the arm to be in a natural, relaxed position, which can help the veins to be more prominent and accessible. It also helps in reducing the patient's anxiety as the arm is not in an awkward or strained position.
