In which of the following locations should a phlebotomist directly dispose of a contaminated microscope slide?
A: Specimen bag
B: Biohazard bag
C: Red sharps container
D: Medical waste container
The Correct Answer is C
Choice A reason:
A specimen bag is typically used for transporting specimens from the collection site to the laboratory. It is not designed for the disposal of contaminated items such as microscope slides. These bags are not puncture-resistant and do not provide the necessary protection against sharps injuries or contamination.
Choice B reason:
A biohazard bag is used for disposing of items that have been contaminated with potentially infectious materials. While it is suitable for materials like gloves, tissues, or any other items that do not have sharp edges, it is not the appropriate choice for glass slides, which can puncture the bag and pose a risk to handlers.
Choice C reason:
A red sharps container is specifically designed for the disposal of sharps waste, which includes any device that can puncture or cut skin, such as needles, syringes, lancets, and contaminated glass such as microscope slides. These containers are rigid, puncture-resistant, leak-proof, and usually marked with a biohazard symbol, making them the correct choice for disposing of contaminated microscope slides.
Choice D reason:
A medical waste container is a broad term that can refer to various types of containers used for medical waste. However, not all medical waste containers are suitable for sharps disposal. Unless the medical waste container is designed like a red sharps container, it may not be safe for disposing of glass slides.

Correct Answer is A
Explanation
Choice A Reason:
SST, or Serum Separator Tube, contains a gel at the bottom to separate the blood from the serum upon centrifugation. It does not indicate plasma; rather, it is used to collect serum after the blood has clotted. The SST allows for the blood to clot and the serum to be separated for various tests that require serum instead of plasma.
Choice B Reason:
Sodium fluoride is a common additive in collection tubes that serves as a glycolysis inhibitor. It preserves glucose levels and is not specifically indicative of serum. However, it is often used in grey-top tubes, which are typically used for glucose testing and may contain plasma, not serum.
Choice C Reason:
Sodium citrate is an anticoagulant that binds calcium in the blood, preventing clotting. Tubes with sodium citrate are used to collect plasma for coagulation studies, not serum. Therefore, this statement is incorrect as sodium citrate indicates plasma, not serum.
Choice D Reason:
EDTA, or Ethylenediaminetetraacetic acid, is an anticoagulant that binds calcium ions, preventing blood from clotting. Tubes with EDTA are used for collecting plasma because they prevent clotting and allow for the separation of plasma from the blood cells upon centrifugation. This is the correct choice as EDTA indicates plasma.
Correct Answer is A
Explanation
Choice A Reason:
When a patient is under "Contact Precautions," it is recommended that healthcare workers don a gown upon entering the patient's room. This is to prevent the spread of infection through contact with the patient or their environment. The gown should be removed before leaving the room to avoid contaminating other areas.
Choice B Reason:
While a face shield may be necessary for certain procedures, it is not specifically required for "Contact Precautions." The primary concern with contact precautions is preventing the transmission of infections through touch, not through droplets, which is what a face shield would protect against.
Choice C Reason:
Donning a mask is not a standard requirement for "Contact Precautions" unless there is a risk of droplet transmission. In this scenario, the precautions are specifically for contact, and therefore, a mask alone would not be sufficient.
Choice D Reason:
Gloves should be donned before any potential contact with the patient or their immediate environment, not just after cleaning and evaluating the venipuncture site. Gloves are a critical component of PPE when dealing with patients under "Contact Precautions."
