Module 9 infection
The concept of infection
1) which actions should the nurse take to help the client with bowel and bladder dysfunction
reduce the risk of infection? Select all that apply.
A) Isolate the client using transmission-based precautions.
B) Monitor intake and output.
C) Provide hygienic care after episodes of incontinence.
D) Use standard precautions when handling linen after episodes of incontinence.
E) Limit fluid intake.
✔✔ 💯correct answer: b, c, d
Explanation: a) monitoring intake and output is important because it can help reveal whether a
client is experiencing dehydration. Dehydration may lead to urinary stasis, which increases the
risk of infection. Similarly, intake and output levels can help reveal urinary retention, which also
heightens the risk of infection. Providing hygienic care after episodes of bowel or bladder
incontinence will ensure that the skin remains intact, reducing the risk of infection. Using proper
biohazard precautions after episodes of incontinence will also reduce the risk of transmitting an
infection. In contrast, limiting fluid intake increases infection risk by putting the client at greater
risk for dehydration. Isolating the client using transmission-based precautions is not necessary
because these precautions are meant to prevent the spread of infection from the client to others,
and this client is not currently experiencing infection.
B) Monitoring intake and output is important because it can help reveal whether a client is

infection. Similarly, intake and output levels can help reveal urinary retention, which also

2) a nurse is planning an in-service on preventing infection for the staff nurses on a hospital's
medical-surgical unit. Which of the following should be the priority teaching point for this
inservice?
A) Raising the temperature in each client's room
B) Assessing vital signs once daily
CONCEPTS OF INFECTION
, CONCEPTS OF INFECTION
C) Wearing a mask for client care
D) Performing hand hygiene
✔✔ 💯correct answer: d
Explanation: a) hand hygiene is always the first and best way to stop the spread of
microorganisms, which cause infections. Raising the temperature in a client's room would
contribute to the growth of microorganisms. Assessing vital signs is important but should be
done more frequently than once daily. Wearing a mask for all clients is not practical and is
unnecessary unless a microorganism is airborne and the client is in isolation.

3) the nurse is assessing a client who is recovering following surgery. Which factor would
increase this client's susceptibility to infection?
A) Intact mucous membranes
B) Presence of an incision
C) Dry skin
D) Active bowel sounds
✔✔ 💯correct answer: b
Explanation: a) this client has a surgical incision, so the body's first line of defense, the skin, is
not intact. Active bowel sounds, dry skin, and intact mucous membranes are factors that help
defend the body against infection.
