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 D
Explanation
Choice A Reason:
A red-top tube is used for serum determinations in chemistry and should be allowed to clot completely, typically for 30 minutes, before centrifugation. Shipping after only 15 minutes may result in incomplete clotting and potentially inaccurate test results.
Choice B Reason:
Serum should not be separated from a lavender-top tube, as this type of tube contains EDTA and is used for whole blood tests, not serum. This indicates a misunderstanding of the tube's purpose and could lead to compromised test results.
Choice C Reason:
A tiger-top tube, also known as a serum separator tube, is used for various chemistry tests. However, bilirubin is light-sensitive, and specimens for bilirubin testing should be protected from light, not shipped in a clear bag. This could lead to degradation of the bilirubin and inaccurate results.
Choice D Reason:
A green-top tube contains heparin and is used for plasma determinations. Ammonia testing requires the plasma to be placed on ice immediately after collection to inhibit the continued production of ammonia from red blood cells. Therefore, shipping in an icy water mixture is the correct procedure to ensure accurate ammonia levels.
In conclusion, the proper preparation and transport of blood specimens are crucial for the accuracy of laboratory tests. The green-top tube for ammonia testing, shipped in an icy water mixture, is the only option that follows the correct protocol for specimen handling and transport.
Correct Answer is B
Explanation
Choice A Reason:
Prepping the site with povidone iodine is not typically associated with hemoconcentration. Povidone iodine is used as an antiseptic to clean the skin before venipuncture to prevent infection. While it's important to allow it to dry to avoid sample contamination, it does not cause hemoconcentration.
Choice B Reason:
Leaving the tourniquet in place for more than 2 minutes can lead to hemoconcentration. A tourniquet is applied to engorge the veins, making them easier to puncture. However, prolonged application can result in fluid being forced out of the vein into the tissue, increasing the concentration of cells and larger molecules in the blood. This can affect certain laboratory test results by artificially increasing the levels of cellular components.
Choice C Reason:
Not refrigerating the specimen within 30 minutes does not cause hemoconcentration. However, it can affect the stability of certain analytes in the blood sample. Refrigeration is necessary for preserving the integrity of certain components of the blood until analysis, but it is unrelated to the concentration of cells within the sample at the time of collection.
Choice D Reason:
Removing the needle before the tourniquet is released does not cause hemoconcentration. This action might lead to other complications, such as hematoma formation, but it does not affect the concentration of cellular elements in the collected sample.
