SECTION 1: CHAIN OF INFECTION & FOUNDATIONAL CONCEPTS (Questions 1–20)
1. The nurse is caring for a patient with a draining wound infected with MRSA. Which link in the chain of
infection is the nurse targeting by wearing gloves and a gown?
A. Infectious agent
B. Portal of entry
C. Mode of transmission
D. Susceptible host
Correct Answer: C
Rationale: Wearing gloves and a gown interrupts the mode of transmission (direct contact) by
preventing the transfer of the infectious agent from the wound drainage to the nurse's hands or
clothing, which could then spread to other patients or surfaces. Contact precautions directly block the
transmission link.
2. Which component of the chain of infection is the target when a nurse wears gloves during a wound
dressing change?
A. Reservoir
B. Portal of exit
C. Mode of transmission
D. Portal of entry
,Correct Answer: D
Rationale: Gloves block the pathogen from entering the next host through broken skin or mucous
membranes (portal of entry).
3. A patient has influenza. The virusladen droplets expelled during coughing represent which link?
A. Infectious agent
B. Reservoir
C. Portal of exit
D. Mode of transmission
Correct Answer: C
Rationale: Droplets leaving the infected host through the respiratory tract represent the portal of exit,
which is how the pathogen leaves the reservoir.
4. Which patient poses the greatest risk as a reservoir for healthcareassociated infections (HAIs)?
A. A 30yearold with a simple fracture
B. A 75yearold with an indwelling urinary catheter and diabetes
C. A 40yearold with a migraine headache
D. A 20yearold with an ankle sprain
Correct Answer: B
Rationale: Older age, diabetes (which immunocompromises the patient), and invasive devices such as an
indwelling catheter increase reservoir potential and HAI risk.
,5. The nurse is working on a plan of care that includes turning, positioning, and adequate nutrition to
help maintain intact skin integrity. This breaks the chain of infection by eliminating which element?
A. Host
B. Mode of transmission
C. Portal of entry
D. Reservoir
Correct Answer: C
Rationale: Broken or impaired skin creates a portal of entry for pathogens. By maintaining intact tissue,
the portal of entry is eliminated.
6. A patient has been experiencing a cough and sore throat for several days. While at work, the patient
sneezed several times while sitting close to a coworker. Two days later, the coworker developed the
same symptoms. What mode of transmission took place?
A. Direct contact
B. Indirect contact
C. Droplet transmission
D. Vector transfer
Correct Answer: C
Rationale: Droplet transmission occurs when infectious agents are propelled through the air (e.g., by
sneezing or coughing) and deposited on a susceptible host's mucous membranes, usually within 3–6
feet.
, 7. The nurse is caring for a patient who develops a fever, chills, and malaise after a surgical procedure.
The patient’s white blood cell count is 14,000/mm³. What stage of infection is this patient likely
experiencing?
A. Incubation period
B. Prodromal stage
C. Illness stage
D. Convalescence
Correct Answer: C
Rationale: The illness stage is when the patient manifests specific signs and symptoms of infection, such
as fever, chills, malaise, and leukocytosis. The pathogen is actively multiplying and causing tissue
damage.
8. A patient being seen in urgent care is complaining of vague and generalized symptoms. What stage of
the infection process is the patient in?
A. Incubation
B. Prodromal
C. Illness
D. Convalescent
Correct Answer: B
Rationale: The prodromal stage is characterized by vague, nonspecific symptoms such as fatigue,
malaise, and lowgrade fever, occurring between the incubation period and the full manifestation of
illness.
