Section 1: Infection Prevention Fundamentals
Q1: Which component of the "Chain of Infection" is a patient recovering from surgery who has a
suppressed immune system considered?
A. Reservoir
B. Portal of Entry
C. Susceptible Host [CORRECT]
D. Mode of Transmission
Correct Answer: C
Rationale: A susceptible host is a person who lacks resistance to an infectious agent. Patients recovering
from surgery, those on immunosuppressants, or those with chronic diseases are classic examples of
susceptible hosts. Breaking this link involves vaccination or boosting immune status. Exam Strategy:
Look for the "who" that is vulnerable to identify the susceptible host.
Q2: A healthcare worker is about to administer an intramuscular injection. According to the CDC
Guideline for Hand Hygiene, which antiseptic hand rub is preferred for routine decontamination of
visibly clean hands?
A. Plain soap and water.
B. Alcohol-based hand rub (ABHR). [CORRECT]
C. Chlorhexidine gluconate (CHG) soap.
,D. Povidone-iodine solution.
Correct Answer: B
Rationale: Alcohol-based hand rubs are the preferred method for routine hand antisepsis in healthcare
settings when hands are not visibly soiled. They are more effective, quicker to apply, and cause less skin
irritation than soap and water. Exam Strategy: Unless hands are visibly dirty or C. diff is suspected, ABHR
is the answer.
Q3: Which of the following represents a "reservoir" for infection in a hospital setting?
A. A contaminated stethoscope.
B. A patient with an active influenza infection.
C. A healthcare worker with a new needlestick injury.
D. The plumbing system colonized with Legionella. [CORRECT]
Correct Answer: D
Rationale: A reservoir is the place where the pathogen lives and multiplies. The plumbing system acts as
an environmental reservoir for Legionella. A patient with active infection is a "source" or "reservoir," but
inanimate objects like plumbing are classic environmental reservoirs. Exam Strategy: Distinguish
between the "source" (patient) and the "reservoir" (where the bug lives/survives).
Q4: During a sterile procedure, a nurse accidentally touches the patient's skin with a sterile gloved hand.
Which link in the chain of infection has been compromised?
A. Mode of transmission.
B. Portal of entry.
C. Reservoir.
D. Portal of exit.
Correct Answer: A
,Rationale: The mode of transmission is the mechanism by which the infectious agent is transferred to
the host. Touching the patient's skin (which is not sterile) transfers potential pathogens to the sterile
field/glove, acting as a transmission vehicle (contact). Exam Strategy: "Transfer" or "movement" of the
bug = Mode of Transmission.
Q5: Which of the following is NOT one of the World Health Organization's (WHO) "5 Moments for Hand
Hygiene"?
A. Before touching a patient.
B. After removing gloves. [CORRECT]
C. After body fluid exposure risk.
D. Before clean/aseptic procedure.
Correct Answer: B
Rationale: The WHO 5 Moments are: 1) Before touching a patient, 2) Before clean/aseptic procedure, 3)
After body fluid exposure risk, 4) After touching a patient, 5) After touching patient surroundings. "After
removing gloves" is a general rule but is encompassed by "After touching a patient" or "After body fluid
exposure." It is not one of the distinct five moments listed. Exam Strategy: Memorize the specific 5
phrases.
Q6: Standard Precautions apply to:
A. Only patients known to be infected with a bloodborne pathogen.
B. All patients, regardless of diagnosis or infection status. [CORRECT]
C. Only patients placed in isolation rooms.
D. Only patients with visible signs of infection.
Correct Answer: B
Rationale: Standard Precautions are the basic infection prevention practices that apply to all patient
care, regardless of suspected or confirmed infection status. They are the primary strategy for preventing
transmission in healthcare settings. Exam Strategy: Standard Precautions = Everyone, always.
, Q7: A patient is placed in a private room for a suspected infection. The door remains open, and visitors
walk in without PPE. This is a failure in which part of the infection control program?
A. Administrative controls.
B. Engineering controls.
C. Isolation precautions. [CORRECT]
D. Antimicrobial stewardship.
Correct Answer: C
Rationale: Isolation precautions involve specific measures (PPE, room placement, signage) to prevent
transmission. Failure to enforce PPE usage or room containment is a direct failure of isolation
precautions. Exam Strategy: Look for the specific action (or lack thereof) related to the patient's
immediate environment.
Q8: Which of the following is an example of a "portal of exit" for a pathogen?
A. A surgical wound.
B. The respiratory tract (via coughing). [CORRECT]
C. The mucous membranes.
D. Non-intact skin.
Correct Answer: B
Rationale: The portal of exit is the path by which the pathogen leaves the reservoir. For a patient with a
respiratory infection, the respiratory tract (coughing/sneezing) is the portal of exit. A surgical wound or
mucous membranes are typically portals of entry. Exam Strategy: Exit = Out; Entry = In.
Q9: A nurse sustains a needlestick injury from a device used on a patient with known Hepatitis B. The
nurse was vaccinated against Hepatitis B 5 years ago and has a documented antibody titer of >10
mIU/mL. What is the primary rationale for this being a low-risk event?
A. Hepatitis B is not transmitted via needlestick.
