The nurse manager is evaluating current infection control data for the intensive care unit. The nurse
compares past patient data with current data to look for trends. The nurse manager examines the
infection chain for possible solutions. In which order will the nurse arrange the items for the infection
chain beginning with the first step?
1. A mode of transmission
2. An infectious agent or pathogen
3. A susceptible host
4. A reservoir or source for pathogen growth
5. A portal of entry to a host
6. A portal of exit from the reservoir
a. 3, 2, 4, 1, 5, 6
b. 1, 3, 5, 4, 6, 2
c. 4, 2, 1, 6, 3, 5
d. 2, 4, 6, 1, 5, 3
ANS: D
For spread of infection, the chain has to be uninterrupted with an infectious agent, a reservoir and
portal of exit, a mode of transmission, a portal of entry, and a susceptible host. The nurse manager is
evaluating the chain of infection to determine actions that could be implemented to influence the
spread of infection in the
intensive care unit. Understanding the spread of infection and directing actions toward those steps
have the potential to decrease infection in the setting.
MULTIPLE RESPONSE
1. The nurse is caring for a patient in protective environment. Which actions will the nurse take?
(Select all that apply.)
a. Wear an N95 respirator when entering the patient’s room.
b. Maintain airflow rate greater than 12 air exchanges/hr.
c. Place in special room with negative-pressure airflow.
d. Open drapes during the daytime.
e. Listen to the patient’s interests.
f. Place dried flowers in a plastic vase.
ANS: B, D, E
This form of isolation requires a specialized room with positive airflow. The airflow rate is set at
greater than 12 air exchanges/hr, and all air is filtered through a HEPA filter. Isolation disrupts normal
social relationships with visitors and caregivers. Take the opportunity to listen to a patient’s concerns or
interests. Open drapes or shades and remove excess supplies and equipment. Patients are not allowed to
have dried or fresh flowers or potted plants in these rooms. All health care personnel wear an N95
respirator every time they enter the room for patients, and a private room with negative airflow is
required for patients on airborne precautions.
2. The nurse is assessing a new patient admitted to home health. Which questions will be most
appropriate for the nurse to ask to determine the risk of infection? (Select all that apply.)
a. “Can you explain the risk for infection in your home?”
b. “Have you traveled outside of the United States?”
c. “Will you demonstrate how to wash your hands?” 1
d. “What are the signs and symptoms of infection?”
, e. “Are you able to walk to the mailbox?”
f. “Who runs errands for you?”
ANS: A, B, C, D
In the home setting, the objective is that the patient and/or family will utilize proper infection control
techniques. Asking the patient and family about handwashing, risk of infection, recent travel, and signs
and symptoms of infection is important in evaluating the patient’s knowledge based on infection control
strategies. Activity assessment is important for evaluation of the overall status of the patient, and
knowing who runs errands gives you information on who is helping to meet the needs of the patient, but
neither of these relates to decreasing the risk of infection.
3. The circulating nurse in the operating room is observing the surgical technologist while applying a
sterile gown and gloves to care for a patient having an appendectomy. Which behaviors indicate to the
nurse that the procedure by the surgical technologist is correct? (Select all that apply.)
a. Ties the back of own gown
b. Touches only the inside of gown
c. Slips arms into arm holes simultaneously
d. Extended fingers fully into both of the gloves
e. Uses hands covered by sleeves to open gloves
f. Applies surgical cap and face mask in the operating suite
ANS: B, C, D, E
To maintain sterility, the surgical technologist (ST) touches the inside of the gown that will be against
the body. Arms are slipped simultaneously into the gown to prevent contamination. Using the sleeves
covering the hands maintains the principle of sterile only touching sterile to open gloves. Extending the
fingers fully into both gloves ensures that the ST has full dexterity while using the sterile gloved hand.
Surgical cap, face mask, and eye wear are applied before entering the surgical area and completing the
surgical scrub. Reaching behind to tie the back of the gown will contaminate the sterile area of the
gown.
4. The nurse is preparing to insert a urinary catheter. The nurse is using open gloving to apply the
sterile gloves. Which steps will the nurse take? (Select all that apply.)
While putting on the first glove, touch only the outside surface of the
a. glove.
With gloved dominant hand, slip fingers underneath second glove
b. cuff.
c. Remove outer glove package by tearing the package open.
d. Lay glove package on clean flat surface above waistline.
e. Glove the dominant hand of the nurse first.
f. After second glove is on, interlock hands.
ANS: B, D, E, F
Sterile objects held below the waist are considered contaminated. Gloving the dominant hand helps to
improve dexterity. Slipping the fingers underneath the second glove cuff helps to keep the gloved
fingers sterile.
Interlocking fingers ensures a smooth fit over the fingers. Sterile supplies are opened by carefully
separating and peeling apart the sides of the package. This prevents the sterile contents from
accidentally opening and touching contaminated objects. While putting on the first glove, touching only
the outside surface of the glove will contaminate the sterile item; touch only the inside of the glove—the
piece that will be against the skin.
5. The nurse has received a report from the emergency department that a patient with tuberculosis
will be coming to the unit. Which items will the nurse need to care for this patient? (Select all that
apply.)
2
a. Private room
, b. Negative-pressure airflow in room
c. Surgical mask, gown, gloves, eyewear
d. N95 respirator, gown, gloves, eyewear
e. Communication signs for droplet precautions
f. Communication signs for airborne precautions
ANS: A, B, D, F
Caring for this patient requires a private room, negative-pressure airflow in room, and wearing an N95
respirator that has been fit-tested, gloves, gown, and eyewear. Tuberculosis is a disease that is
transmitted by droplets that remain in the air for long periods of time, requiring airborne precautions.
This patient will not be in droplet precautions and instead requires airborne precaution signs. This type
of patient requires more than the average surgical mask for protection.
6. The nurse and the student nurse are caring for two different patients on the medical-surgical unit. One
patient is in airborne precautions, and one is in contact precautions. The nurse explains to the student
different interventions for care. Which information will the nurse include in the teaching session?
(Select all that apply.)
a. Dispose of supplies to prevent the spread of microorganisms.
b. Wash hands before entering and leaving both of the patients’ rooms.
Be consistent in nursing interventions since there is only one
c. difference in the precautions.
Apply the knowledge the nurse has of the disease process to prevent
d. the spread of microorganisms.
Have patients in airborne precautions wear a mask during
e. transportation to other departments.
Check the working order of the negative-pressure room for the
f. airborne precaution patient on admission and at discharge.
ANS: A, B, D, E
Washing hands, properly disposing of supplies, applying knowledge of the disease process, and having
patients in airborne precautions wear a mask during transfer are all principles to follow when caring for
patients in isolation. Multiple differences are evident among these types of isolation, including the type
of room used for the patient and what the nurse wears while caring for the patient. It is important to
check the working order of a negative-pressure room before admitting a patient to the room, each shift
the patient is in the room, and if and when the device alarms. Checking the working order of the
negative-pressure rooms at discharge is not necessary.
