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 C
Explanation
Choice A Reason:
Signing a release for laboratory results is a form of expressed consent, not implied consent. Expressed consent is given explicitly, either orally or in writing, and is clearly and unmistakably communicated. It involves a clear action of agreement to the specific procedure or intervention proposed.
Choice B Reason:
Signing a document of agreement for a research study is also an example of expressed consent. The patient is actively agreeing to participate in the study, which is a direct and informed action. This type of consent is necessary for research studies to ensure that participants are fully aware of the study's nature and any potential risks involved.
Choice C Reason:
Implied consent occurs when a patient's actions suggest consent without verbal or written confirmation. Offering an arm to a phlebotomist is a non-verbal communication that implies the patient is willing to have their blood drawn. This is a common practice in medical settings where the action of presenting an arm indicates readiness for the procedure.
Choice D Reason:
A family member nodding for a phlebotomist to proceed does not constitute the patient's implied consent. Consent must come directly from the patient unless they are unable to provide it, in which case a legal surrogate may give consent on their behalf. The nod of a family member cannot be assumed as the patient's consent.
Correct Answer is D
Explanation
Choice A reason:
Covering a quarter of the slide is not an acceptable criterion for the quality of a peripheral blood smear. The smear should be spread across the slide in a manner that allows for proper examination under a microscope, and covering only a quarter of the slide would not provide enough area for an adequate assessment.
Choice B reason:
Having a well-defined edge is not specifically indicative of the quality of a peripheral blood smear. While the edges should be clean to allow for clear viewing of the cells at the margins, the quality is more accurately determined by the distribution and integrity of the cells on the slide.
Choice C reason:
Covering the entire slide is also not a criterion for a quality peripheral blood smear. In fact, if the blood covers the entire slide, it may be too thick to allow for proper cell differentiation and examination. A proper smear should have a gradient of cell distribution, ending with a feathered edge.
Choice D reason:
A feathered edge is the correct criterion for a quality peripheral blood smear. The feathered edge is the thinnest part of the smear and is where the cells are ideally distributed in a single layer, which is optimal for microscopic examination. This allows for the best visualization of cell morphology and is essential for accurate diagnosis.
