MODULE 1-INFECTION CONTROL EXAM
QUESTIONS WITH COMPLETE
SOLUTIONS
/. When should you perform hand hygiene? (Select all that apply.)
a. Before applying gloves to insert an IV.
b. After documenting in the patient's electronic medical record.
c. After moving a patient up in bed.
d. Before assessing a patient's vital signs.
e. Before touching clean linens. - Answer-✅a c d
You should perform hand hygiene before putting on sterile gloves and before inserting
indwelling urinary catheters, peripheral vascular catheters, or other invasive devices.
You should perform hand hygiene after contact with a patient's intact skin (e.g., after
assessing a patient's vital signs or moving a patient in bed). Unless the hands are
visibly soiled, it is unnecessary to perform hand hygiene after documentation. If you
touch an object that is not visibly soiled, such as clean linens, hand washing is
unnecessary at that time.
/.You are washing your hands in a sink with hand faucets. You first turn on the water
and regulate the temperature to warm. You increase the water pressure to create a
strong spray. You wet your hands, apply 1 teaspoon (5 mL) of soap, and rub your hands
together vigorously, creating lather. You interlace your fingers and rub the palms and
backs of the hands with a circular motion at least 5 times each. You keep your hands
positioned with fingertips down and rinse the hands and wrists thoroughly. You turn off
the faucet. You dry your hands with a paper towel. Which step(s) are incorrect? (Select
all that apply.)
a. The temperature of the water.
b. The amount of soap used.
c. The position of your hands.
d. The method used to turn off the faucet.
e. The force of the water.
f. The technique used in lathering. - Answer-✅d e
The temperature of the water should be warm. Water that is too hot can cause injury to
the hands, promoting cracks in the skin. The force of the water (a strong spray) is likely
to cause splashing water against the uniform. Microorganisms travel and grow in
moisture, so getting the uniform wet should be avoided. You should use 3 to 5 mL of
detergent. You correctly lathered your hands. The position of your hands with fingertips
down is correct. The faucet should be turned off with a new, clean paper towel, usually
done after drying the hands.
, /.Under which circumstance(s) should hand washing be repeated? (Select all that
apply.)
A. Hands touch the sink during hand washing.
B. Areas under fingernails remain soiled.
C. Cracked areas are noted on the nurse's hands.
D. Hands are free of visible soiling.
E. Hands are lowered below waist level. - Answer-✅a b
The inside of the sink is a contaminated area. If the hands touch the sink during hand
washing, the hand-washing procedure should be repeated. If the hands or areas under
fingernails remain soiled, repeat hand washing with soap and water. If the nurse's
hands are cracked, rinse and dry hands thoroughly. Hand washing does not require
repeating as this would only dry out the skin more. Hands lowered below the waist do
not require repeated hand washing because this skill is using clean technique, not
sterile technique.
/.Why are the hands rinsed with the fingertips held lower than the wrist?
A. Water flows from the least to the most contaminated area, rinsing microorganisms
into the sink.
B. To keep the sleeves from getting wet.
C. It is necessary to ensure that all surfaces of the hands, including under the nails, are
cleansed.
D. To loosen and remove dirt and bacteria. - Answer-✅a
The hands and forearms are kept lower than the elbows, and the fingertips are kept
lower than the wrists during washing to promote the flow of water from the least to the
most contaminated area, rinsing microorganisms into the sink. Use of an adequate
amount of detergent and vigorous lathering and rubbing of the hands together for an
appropriate length of time (15 seconds) ensures that all surfaces of the hands and
fingers are covered and cleansed. Friction and rubbing mechanically loosen and
remove dirt and transient bacteria.
/.What is the best nursing practice to reduce the potential transmission of
microorganisms within the health care setting?
A. Bagging all linen.
B. Performing hand hygiene.
C. Keeping catheter bags empty.
D. Wearing gloves. - Answer-✅b
The best practice to prevent the transmission of microorganisms for all caregivers is
performing hand hygiene before and after patient contact.
/.When is it acceptable to use antiseptic hand rub rather than soap and water? (Select
all that apply.)
A. After adjusting a nasal cannula on a patient
B. After removing gloves after changing a wound dressing.
C. When the nurse's hands are cracked from frequent hand hygiene.
D. After moving patient's belongings on the bedside table.
