B260 Infection Control QuizAbove the elbows
Keeping the hands above the elbows when performing a surgical scrub prevents contaminated
water from coming into contact with the hands. - ANS-When the nurse is performing surgical
hand asepsis, where should the nurse keep his or her hands?
Wearing rings on both hands
While performing hand hygiene, finger rings should be removed. Wearing rings increases the
risk for infection because the skin underneath the rings carries a high bacterial load. The nail
tips should be less than a quarter-inch long. Antiseptic should be applied on the palm and both
hands should be rubbed together. Any wristwatches and long uniform sleeves should be pushed
above the wrist to provide complete access to the fingers, hands, and wrists. - ANS-A nurse
performs hand hygiene before providing direct patient care. Which action made by the nurse
may cause an infection?
Remove gloves and perform hand hygiene before administering the medication.
Gloves need to be changed and hand hygiene performed to prevent transfer of microorganisms
from one source (the wound) to another (the nurse's hands). Gloves are not a foolproof method
of preventing contamination of the nurse's hands so it is necessary to perform hand hygiene
according to approved protocol. Medications should never be left at the bedside. It is the nurse's
responsibility to ensure that patients take their medications. - ANS-The nurse has redressed a
patient's wound and now plans to administer a medication to the patient. Which is the correct
infection control procedure?
Stool specimen
Stool specimens are collected with sterile tongue blades. Urine specimens are collected with
needleless safety syringes. Blood specimens are collected with 20-mL needle-safe syringes.
Wound specimens are collected with sterile cotton-tipped swabs or syringes and collection
tubes. - ANS-Which type of specimen is collected by using a sterile tongue blade?
Pouring a small amount in a disposable cap before pouring in the container
While pouring a sterile liquid into a container, a small amount of liquid should be poured in a
disposable cap before it is poured into the container because the discarded solution cleans the
lip of the bottle. The cap should be placed with its inner surface facing upwards on the table
because the inner surface should not be contaminated. The nurse should hold the bottle with its
label in the palm of the hand to prevent the possibility of the solution wetting and fading the
, label. The edge of the bottle should be kept away from the container. - ANS-The nurse pours a
sterile liquid into a container. Which action made by the nurse is appropriate?
1. Holding the bottle with its label pointed outside the palm of the hand
2. Placing the cap with the inner surface facing down on the table
3. Keeping the edge of the bottle close to the edge of the container
4. Pouring a small amount in a disposable cap before pouring in the container
Medical unit I
Laryngeal tuberculosis is an airborne infection that spreads through small droplets. Therefore,
the nurse should use an N95 respirator to prevent infection in medical unit I. Shigella infection
spreads through contact; contact precautions should be followed in medical unit II. Scabies
spreads through contact; contact precautions should be followed in medical unit III.
Disseminated varicella zoster spreads through contact; contact precautions should be followed
in medical unit IV.
Test-Taking Tip: Chart/exhibit items present a situation and ask a question. A variety of objective
and subjective information is presented about the patient in formats such as the medical record
(e.g., laboratory test results, results of diagnostic procedures, progress notes, health care
provider orders, medication administration record, health history), physical assessment data,
and assistant/patient interactions. After an - ANS-The nurse provides care to four patients with
different medical conditions in four units. In which medical unit should the nurse use an N95
respirator? (cannot u/l image)
Blood or body fluids may get on the nurse's clothing from a task that he or she plans to perform.
The gown serves as a barrier between the patient's blood and/or body fluids and potential
contact with the caregiver's skin. In some cases, if the patient's hygiene is unacceptable, it may
require the nurse to wear a gown, but it is not the best answer. It is not necessary to wear a
gown during medication administration or if the patient has AIDS or hepatitis. - ANS-When does
the nurse wear a gown?
Vehicles
Human immunodeficiency virus (HIV) infections are transmitted through vehicles such as blood
and body fluids. Vectors such as mosquitoes transmit malaria. Infections such as Ebola and
tuberculosis are transmitted by droplet nuclei. Infections such as influenza, Ebola, and
tuberculosis are airborne. - ANS-Which is a mode of transmission for the human
immunodeficiency virus (HIV) infection?
It obstructs the normal flushing action of urine flow.
