A patient who is on droplet precautions requires daily blood glucose monitoring. Besides gloves, which piece of personal protective equipment must the phlebotomist wear when drawing the sample?
Shoe covers
Mask
Gown
Goggles
The Correct Answer is B
Choice A Reason:
Shoe covers are used to protect the shoes and prevent the spread of contaminants from one area to another. They are not specifically required for droplet precautions during blood glucose monitoring. Droplet precautions typically focus on protecting mucous membranes of the eyes, nose, and mouth from droplet spatter.
Choice B Reason:
Masks are essential when dealing with patients under droplet precautions. Droplets can transmit infections when a person coughs, sneezes, or talks, and a mask provides a barrier that prevents the inhalation of these potentially infectious droplets. For procedures like blood glucose monitoring, where close contact with the patient is necessary, wearing a mask is crucial to protect both the healthcare worker and the patient.
Choice C Reason:
A gown is used to protect the healthcare worker's skin and clothing from contamination with potentially infectious material. While it is an important piece of personal protective equipment, it is not the primary requirement for droplet precautions in the context of blood glucose monitoring, unless there is a risk of substantial splashing or spraying of bodily fluids.
Choice D Reason:
Goggles are used to protect the eyes from splashes of blood or other body fluids. They are important in procedures where there is a risk of splashing, but for blood glucose monitoring, the risk is minimal. Therefore, goggles are not the primary piece of equipment required for droplet precautions in this scenario.

Correct Answer is B
Explanation
Choice A reason:
Cleaning the site is a step that should be completed before anchoring the vein. The site should be cleaned with an antiseptic to reduce the risk of infection. Once the vein is anchored, cleaning the site again could displace the vein and compromise the anchoring.
Choice B reason:
After anchoring the vein, the phlebotomist should perform the procedure, which involves inserting the needle into the vein at the appropriate angle. Once the needle is in place and blood is seen in the tubing, the phlebotomist can proceed to collect the necessary amount of blood into the vacutainers or syringe.
Choice C reason:
Examining the needle is not the next step after anchoring the vein. The needle should be examined before the procedure begins to ensure it is the correct size and gauge for the venipuncture and that there are no defects.
Choice D reason:
Reapplying the tourniquet is not necessary at this point in the procedure. The tourniquet should already be in place to engorge the vein, making it easier to anchor and access. Reapplying it could cause discomfort or even disrupt the already anchored vein.
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.
