Infection Control & Standard Precautions
Q1: A nursing student is reviewing the chain of infection. Which link in the chain
represents the person or animal that harbors the infectious agent?
A. Portal of entry
B. Reservoir [CORRECT]
C. Mode of transmission
D. Susceptible host
Correct Answer: B
Rationale: The best answer is B. Think about the chain of infection here — the reservoir
is where the pathogen lives and multiplies, whether that's a person, animal, or the
environment. You have to break one link to stop infection from happening, and
identifying the reservoir is step one.
Q2: A nurse is caring for a patient with a draining wound caused by methicillin-resistant
Staphylococcus aureus (MRSA). In addition to standard precautions, which
transmission-based precaution is required?
A. Droplet precautions
B. Airborne precautions
C. Contact precautions [CORRECT]
D. Protective environment
Correct Answer: C
Rationale: This is correct because MRSA is spread by direct contact with the patient or
contaminated surfaces and equipment. Contact precautions mean gown and gloves on
entry, and dedicated equipment when possible. Remember what we covered in lab
about multi-drug resistant organisms — they all get contact precautions.
,Q3: A nurse enters the room of a patient on droplet precautions for pertussis. Which
PPE items are required before entering the room?
A. N95 respirator, gown, and gloves
B. Gown and gloves only
C. Surgical mask, gown, and gloves [CORRECT]
D. Surgical mask only
Correct Answer: C
Rationale: The best answer is C. Droplet precautions require a surgical mask — not an
N95 — because the particles are larger and travel within about 3 feet. You still need
gown and gloves for standard precautions, but the mask is what makes it
droplet-specific.
Q4: A patient with suspected pulmonary tuberculosis is admitted to the unit. Which type
of isolation room is required?
A. Standard private room
B. Negative pressure airborne infection isolation room (AIIR) [CORRECT]
C. Positive pressure room
D. Contact isolation room with anteroom
Correct Answer: B
Rationale: This aligns with standard precautions because TB is airborne — those tiny
particles can float in the air for hours. A negative pressure room pulls air in and filters it
out so it doesn't escape into the hallway. Staff also need fit-tested N95 respirators or
PAPRs.
Q5: When donning personal protective equipment, which sequence is correct?
A. Gown, mask, goggles, gloves [CORRECT]
B. Mask, gloves, gown, goggles
C. Gloves, gown, mask, goggles
D. Goggles, mask, gown, gloves
Correct Answer: A
Rationale: The best answer is A. Remember what we covered in lab about donning —
gown goes on first, then the mask or respirator, then eye protection, and gloves always
go on last so you can adjust everything else without contaminating your hands.
, Q6: A nurse is removing PPE after caring for a patient in contact precautions. Which is
the correct first step in doffing?
A. Remove the gown
B. Remove the gloves [CORRECT]
C. Remove the face shield
D. Perform hand hygiene
Correct Answer: B
Rationale: This is correct because gloves are the most contaminated item and come off
first during doffing. You peel them off using glove-to-glove and skin-to-skin technique,
then you can remove the gown and eye protection, and finish with hand hygiene.
Q7: Which action best represents medical asepsis rather than surgical asepsis?
A. Performing hand hygiene before and after patient contact [CORRECT]
B. Opening a sterile package using sterile technique
C. Donning sterile gloves to insert a urinary catheter
D. Creating a sterile field for a dressing change
Correct Answer: A
Rationale: The best answer is A. Medical asepsis — what we call clean technique — is
about reducing the number of pathogens, like hand hygiene and using clean gloves.
Surgical asepsis is sterile technique, where you eliminate all microorganisms, and that's
what you need for invasive procedures.
Q8: A nurse is preparing to change a sterile dressing on a central line insertion site. The
nurse accidentally touches the inside of the sterile dressing package with a bare hand.
What is the appropriate action?
A. Continue since the outside of the package is still clean
B. Use the dressing anyway if the site looks clean
C. Discard the dressing and open a new sterile package [CORRECT]
D. Wipe the dressing with alcohol and proceed
Correct Answer: C
Rationale: This aligns with standard precautions because once sterility is broken, it's
broken — there's no fixing it. The inside of that package and the dressing are considered
contaminated, and using it could introduce pathogens directly into the patient's
bloodstream.
