A nurse is implementing respiratory isolation precautions for a patient. Which action
would most likely result in a break in sterile technique for respiratory isolation?
a. Opening the patient's window to the outside environment
b. Turning on the patient's room ventilator
,c. Opening the door of the patient's room leading into the hospital corridor
d. Failing to wear gloves when administering a bed bath
✔️ Correct Answer: C
Rationale:
Respiratory isolation requires that the door to the patient's room remain closed to
prevent the spread of airborne pathogens to the corridor. Opening the door into the
hospital corridor would break isolation technique. Option C is correct. Opening the
window or turning on the ventilator improves ventilation, which is desirable in
respiratory isolation. Gloves are not specifically required for respiratory isolation unless
contact with body fluids is anticipated.
A nurse completes routine patient contact and prepares to perform hand hygiene.
According to standard guidelines, hand washing should last at least:
a. 30 seconds
b. 1 minute
c. 2 minutes
d. 3 minutes
✔️ Correct Answer: A
Rationale:
After routine patient contact, hand washing for at least 30 seconds effectively minimizes
the risk of pathogen transmission. Option A is correct. Depending on the degree of
exposure to pathogens, hand washing may last from 10 seconds to 4 minutes, but 30
seconds is the minimum recommended duration for routine contact.
A nurse is preparing to perform hand washing. Effective hand washing requires the use
of:
a. Soap or detergent to promote emulsification
b. Hot water to destroy bacteria
c. A disinfectant to increase surface tension
d. All of the above
✔️ Correct Answer: A
Rationale:
Soaps and detergents are used to help remove bacteria because of their ability to lower
the surface tension of water and act as emulsifying agents. Option A is correct. Hot
, water may lead to skin irritation or burns and is not necessary for effective hand
washing. Disinfectants are not required for routine hand washing.
A nurse is assessing patients for infection risk. Which patient is at greater risk for
contracting an infection?
a. A patient with leukopenia
b. A patient receiving broad-spectrum antibiotics
c. A postoperative patient who has undergone orthopedic surgery
d. A newly diagnosed diabetic patient
✔️ Correct Answer: A
Rationale:
Leukopenia is a decreased number of leukocytes (white blood cells), which are essential
for resisting infection. This places the patient at significantly increased risk for
contracting infections. Option A is correct. While broad-spectrum antibiotics,
postoperative status, and diabetes can increase infection risk, leukopenia represents the
most significant immunosuppressed state.
A nurse is preparing to perform a procedure that requires surgical asepsis. Which
procedure always requires surgical asepsis?
a. Vaginal instillation of conjugated estrogen
b. Urinary catheterization
c. Nasogastric tube insertion
d. Colostomy irrigation
✔️ Correct Answer: B
Rationale:
The urinary system is normally free of microorganisms except at the urinary meatus. Any
procedure that involves entering this system, such as urinary catheterization, must use
surgical aseptic measures to maintain a bacteria-free state and prevent urinary tract
infections. Option B is correct. Vaginal instillation, nasogastric tube insertion, and
colostomy irrigation may require clean technique but not necessarily surgical asepsis.
In the circular chain of infection, which element can be eliminated by preserving skin
integrity?
