Section 1: Infection Control & Standard Precautions
Question 1
Question: Standard Precautions should be practiced on: A) Only residents with known infectious
diseases
B) Every single person under a Nursing Assistant’s care
C) Residents in intensive care units
D) Patients diagnosed with bloodborne pathogens
Correct Answer: B) Every single person under a Nursing Assistant’s care
Rationale: Standard Precautions are universal safety measures designed to prevent the
transmission of disease. Because infection status cannot always be determined by visual
inspection or medical history alone, NAs must treat all blood, body fluids, non-intact skin, and
mucous membranes as potentially infectious for all residents.
Question 2
Question: Which federal agency is responsible for establishing safety standards to protect
workers from hazards on the job? A) CDC (Centers for Disease Control and Prevention)
B) FDA (Food and Drug Administration)
C) OSHA (Occupational Safety and Health Administration)
D) CMS (Centers for Medicare & Medicaid Services)
,Correct Answer: C) OSHA (Occupational Safety and Health Administration)
Rationale: OSHA enforces safety regulations in healthcare workplaces to protect employees
from occupational hazards, including bloodborne pathogens, chemical exposures, and ergonomic
injuries.
Question 3
Question: What is the most single effective way to prevent the spread of infection in a
healthcare facility? A) Wearing double gloves at all times
B) Proper hand hygiene (washing hands with soap and water or alcohol rub)
C) Keeping resident room doors closed
D) Spraying disinfectant air fresheners
Correct Answer: B) Proper hand hygiene (washing hands with soap and water or alcohol rub)
Rationale: Hand hygiene breaks the chain of infection by removing or killing microorganisms
picked up from surface contact or resident care, making it the single most critical infection
control practice.
Question 4
Question: How long should a Nursing Assistant rub hands together with lathered soap during
handwashing? A) At least 5 seconds
B) At least 10 seconds
C) At least 20 seconds
D) At least 60 seconds
Correct Answer: C) At least 20 seconds
Rationale: CDC guidelines recommend scrubbing all surfaces of the hands with soap for at least
20 seconds to effectively loosen and remove pathogens.
Question 5
Question: Where should sharp objects, such as used razor blades or needles, be disposed of? A)
Standard trash container
B) Biohazard bag
C) Rigid, leak-proof biohazard sharps container
D) Dirty utility sink
Correct Answer: C) Rigid, leak-proof biohazard sharps container
, Rationale: Sharps pose a risk of needle sticks or cuts that can transmit bloodborne pathogens.
They must be discarded immediately into puncture-resistant biohazard sharps containers.
Question 6
Question: Why should a Nursing Assistant avoid wearing artificial nails or long acrylics to
work? A) They hinder typing speed
B) They harbor microorganisms and increase the risk of infection transmission
C) They tear resident clothing easily
D) They are prohibited by state tax laws
Correct Answer: B) They harbor microorganisms and increase the risk of infection transmission
Rationale: Fungal and bacterial pathogens readily collect beneath artificial nails and resist
standard hand hygiene, posing a significant infection risk to vulnerable residents.
Question 7
Question: Which link in the chain of infection describes the path by which a pathogen leaves the
host body? A) Reservoir
B) Mode of transmission
C) Portal of exit
D) Susceptible host
Correct Answer: C) Portal of exit
Rationale: The portal of exit is any body opening or route (such as the respiratory tract, broken
skin, blood, or GI tract) through which an infectious agent leaves the reservoir host.
Question 8
Question: Transmission-Based Precautions are used: A) In place of Standard Precautions
B) In addition to Standard Precautions for residents who are known or suspected to be infected
C) Only for elderly residents
D) Whenever a resident has a non-contagious chronic illness
Correct Answer: B) In addition to Standard Precautions for residents who are known or
suspected to be infected
Rationale: Transmission-Based Precautions (Airborne, Droplet, Contact) add specific personal
protective equipment (PPE) and isolation procedures on top of Standard Precautions tailored to
specific transmission modes.
