Question 1: Which of the following is the primary purpose of OSHA in healthcare
settings?
A. To regulate patient billing practices
B. To oversee hospital accreditation
C. To ensure workplace safety and reduce occupational hazards
D. To manage public health vaccination programs
CORRECT ANSWER: C. To ensure workplace safety and reduce occupational
hazards
Rationale: The Occupational Safety and Health Administration (OSHA) was established
to ensure safe and healthful working conditions by setting and enforcing standards and
providing training, outreach, education, and assistance. In healthcare, this includes
minimizing exposure to bloodborne pathogens, hazardous chemicals, and ergonomic
risks.
Question 2: What does the term "standard precautions" refer to in infection
control?
A. Use of PPE only during surgical procedures
B. Isolation protocols for patients with known infections
C. Basic infection prevention practices applied to all patients regardless of diagnosis
D. Handwashing only when visibly soiled
CORRECT ANSWER: C. Basic infection prevention practices applied to all patients
regardless of diagnosis
Rationale: Standard precautions are the minimum infection prevention practices that
apply to all patient care, regardless of suspected or confirmed infection status. They
include hand hygiene, use of personal protective equipment (PPE), safe injection
practices, and proper handling of potentially contaminated equipment or surfaces.
Question 3: Which OSHA standard specifically addresses occupational exposure to
bloodborne pathogens?
A. Hazard Communication Standard
B. Bloodborne Pathogens Standard (29 CFR 1910.1030)
C. Respiratory Protection Standard
D. Emergency Action Plans Standard
CORRECT ANSWER: B. Bloodborne Pathogens Standard (29 CFR 1910.1030)
,Rationale: The OSHA Bloodborne Pathogens Standard (29 CFR 1910.1030) is designed
to protect workers from health hazards caused by bloodborne pathogens. It mandates
exposure control plans, use of engineering and work practice controls, PPE, training,
and post-exposure follow-up.
Question 4: When should healthcare workers perform hand hygiene according to
the WHO’s “Five Moments”?
A. Only before eating
B. Before touching a patient, before clean/aseptic procedures, after body fluid exposure
risk, after touching a patient, and after touching patient surroundings
C. Only after removing gloves
D. Once per shift
CORRECT ANSWER: B. Before touching a patient, before clean/aseptic procedures,
after body fluid exposure risk, after touching a patient, and after touching patient
surroundings
Rationale: The World Health Organization’s “Five Moments for Hand Hygiene” provide a
framework for effective hand hygiene in healthcare settings to reduce the transmission
of microorganisms. These moments cover critical points where hand hygiene is
essential to prevent cross-contamination.
Question 5: Which of the following best describes an engineering control in
infection prevention?
A. Training staff on proper glove use
B. Using a sharps container for used needles
C. Wearing a gown during patient care
D. Posting signs about isolation precautions
CORRECT ANSWER: B. Using a sharps container for used needles
Rationale: Engineering controls are designed to isolate or remove the hazard from the
workplace. Sharps containers safely contain used needles and other sharp
instruments, reducing the risk of needlestick injuries and exposure to bloodborne
pathogens.
Question 6: What is the correct sequence for donning PPE when entering an
isolation room requiring contact and droplet precautions?
A. Gown, mask/respirator, goggles/face shield, gloves
B. Mask/respirator, goggles/face shield, gown, gloves
C. Gloves, gown, mask, goggles
D. Goggles, gloves, gown, mask
CORRECT ANSWER: A. Gown, mask/respirator, goggles/face shield, gloves
, Rationale: The recommended sequence for donning PPE is: gown first, then mask or
respirator, followed by goggles or face shield, and finally gloves. This order minimizes
contamination of clean areas and ensures full coverage before patient contact.
Question 7: Which hepatitis virus is most commonly transmitted via percutaneous
exposure in healthcare settings?
A. Hepatitis A
B. Hepatitis B
C. Hepatitis C
D. Hepatitis E
CORRECT ANSWER: B. Hepatitis B
Rationale: Hepatitis B virus (HBV) is highly infectious and can survive outside the body
for up to seven days. It is efficiently transmitted through percutaneous exposures such
as needlesticks, making it a significant occupational hazard in healthcare despite the
availability of a vaccine.
Question 8: What is the primary mode of transmission for tuberculosis (TB) in
healthcare settings?
A. Contact with contaminated surfaces
B. Fecal-oral route
C. Airborne droplet nuclei
D. Vector-borne transmission
CORRECT ANSWER: C. Airborne droplet nuclei
Rationale: Tuberculosis is caused by Mycobacterium tuberculosis and spreads through
airborne droplet nuclei generated when an infected person coughs, sneezes, or speaks.
These tiny particles can remain suspended in air for hours, necessitating airborne
precautions including N95 respirators and negative-pressure rooms.
Question 9: According to OSHA, how soon must an employer offer a hepatitis B
vaccine to at-risk employees?
A. Within 10 days of initial assignment
B. At no cost and within 10 working days of initial assignment
C. Only after a documented exposure
D. After the employee requests it in writing
CORRECT ANSWER: B. At no cost and within 10 working days of initial assignment
Rationale: OSHA’s Bloodborne Pathogens Standard requires employers to make the
hepatitis B vaccine available at no cost to employees whose jobs involve occupational
exposure to blood or other potentially infectious materials, and this must occur within
10 working days of initial assignment.
