GRADED
1. Which agency is primarily responsible for enforcing the Bloodborne
Pathogens Standard in the clinical laboratory setting?
A. CDC
B. FDA
C. OSHA
D. CLSI
Answer: C. OSHA, the Occupational Safety and Health Administration, is
the federal body that promulgates and enforces workplace safety
regulations, including 29 CFR 1910.1030, the Bloodborne Pathogens
Standard, which mandates employer protocols to reduce occupational
exposure to blood and other potentially infectious materials.
2. In the chain of infection, the phlebotomist’s non-intact skin is best
described as which element?
A. Reservoir
B. Portal of exit
C. Mode of transmission
,2|Page
D. Portal of entry
Answer: D. A portal of entry is the route by which a pathogen gains
access to a susceptible host. A break in the phlebotomist’s skin provides
a direct pathway for microorganisms to enter the body and establish
infection.
3. Which of the following statements regarding hand hygiene in
phlebotomy is correct?
A. Handwashing with soap and water is acceptable even if hands are
not visibly soiled.
B. Alcohol-based hand rubs are ineffective against Clostridioides difficile
spores.
C. Sterile gloves may be used as a substitute for handwashing.
D. Hand hygiene is only necessary after removing gloves.
Answer: B. Alcohol-based hand rubs do not reliably kill Clostridioides
difficile spores due to their inherent resistance. When exposure to
spore-forming organisms is suspected, soap and water handwashing
with friction is required for mechanical removal.
4. A phlebotomist is about to perform venipuncture on a patient with
active tuberculosis. Which combination of personal protective
equipment represents the minimum standard?
A. Gloves and goggles
B. Gloves, gown, and N95 respirator
C. Gloves and surgical mask

D. Gloves, N95 respirator, and shoe covers
Answer: B. Tuberculosis is transmitted via airborne droplet nuclei.
Standard precautions plus airborne infection isolation require the use
of gloves, a fluid-resistant gown if splashing is anticipated, and a fit-
tested N95 particulate respirator.
5. What is the proper order for donning personal protective
equipment?
A. Gloves, mask, gown, eyewear
B. Gown, mask, eyewear, gloves
C. Mask, gown, gloves, eyewear
D. Eyewear, mask, gown, gloves
Answer: B. The sequence gown, mask or respirator, eyewear, then
gloves minimizes contamination risk during the donning process. The
gown is secured first to cover clothing, the mask establishes respiratory
protection, and gloves are applied last to cover the gown cuffs.
6. An acid-fast bacillus smear and culture has been ordered. What
specific infection control precaution should guide the phlebotomist’s
specimen collection?
A. Contact precautions
B. Droplet precautions
C. Airborne precautions
D. Enteric precautions
, 4|Page
Answer: C. Acid-fast bacilli, most commonly Mycobacterium
tuberculosis, are transmitted via airborne droplet nuclei. Airborne
precautions, including use of a negative-pressure room and N95
respirator for the phlebotomist, are required.
7. The primary intent of the Needlestick Safety and Prevention Act is to
mandate which of the following?
A. Annual bloodborne pathogen training
B. Hepatitis B vaccination for all employees
C. Use of safety-engineered sharps devices
D. Post-exposure prophylaxis documentation
Answer: C. The Needlestick Safety and Prevention Act revised the OSHA
Bloodborne Pathogens Standard to require employers to implement
and annually update safer medical devices, such as retractable needles
and needleless systems, to reduce sharps injuries.
8. Which immunoglobulin is the most abundant in human serum and
provides long-term humoral immunity?
A. IgA
B. IgM
C. IgE
D. IgG
Answer: D. Immunoglobulin G (IgG) constitutes approximately 75-80%
of total serum immunoglobulins. It is the primary antibody of secondary
