Answer Keys - Critical Thinking Questions

Nursing Care Plan 7-1: The Patient with an Infection

1. Mr. R. has a peripheral IV infusing and reports discomfort at the site of insertion. What
should the nurse do?

The nurse should immediately assess the IV site for obvious dislodgment of the IV catheter,
edema, erythema, or increased warmth or coolness. Coolness may indicate IV infiltration; the
other signs may indicate irritation (possibly from a previously administered medication or as an
adverse effect of it) or infection.

In general, if an IV site is obviously infiltrated, nursing judgment is sufficient to determine
whether to stop the IV infusion and/or remove the infiltrated IV catheter. Warm compresses may
generally be applied per nursing judgment as well. (Facility policies must be verified.)

The health care provider must be notified so that the determination can be made regarding the
necessity to restart a new intravenous access site.

2. Mr. R. has a urinary catheter connected to continuous drainage. He reports burning at the site
of insertion and the nurse notes dark, concentrated urine in the tubing. What should the nurse do
next?

The nurse should assess the site of the catheter insertion for any signs of edema, erythema, or
exudate. The nurse should then take the patient’s vital signs, noting any changes in temperature
and pulse. Compare the data obtained with patient’s previous vital signs.??

Following these nursing actions, the nurse should obtain urine samples for urinalysis and culture
and sensitivity (using aseptic technique), in anticipation of the health care provider’s orders to
come.

All of the above should then be reported to the patient’s health care provider as promptly as
possible. The nurse should also encourage the patient to increase his fluid intake. Make
additional fluids available to him, if not contraindicated.

3. The nurse notes on the sheet of laboratory results for Mr. R. that his WBC count is 2800/mm3.
Why is this a concern, and what is recommended as a precautionary measure?

This indicates a severely compromised immune system, placing the patient at very high risk for
infection. The patient is especially susceptible to microorganisms that normally do not pose a
significant threat to a healthy immune system. A healthy immune system will destroy or

deactivate most pathogens before they can multiply into greater numbers. If a patient is
immunocompromised, even weaker or opportunistic pathogens (herpes varicella virus or CMV)
can become established and cause infection or disease. Often this is in a more severe form
because the patient also cannot initiate an effective immune response to combat it.

Mr. R. should be placed on neutropenic precautions (formerly known as reverse isolation or
Protective Isolation). The intent of neutropenic precautions is to minimize threats to the patient’s
compromised immune status; for instance, protecting the patient from his or her environment.
Most facilities have specific protocols for implementing neutropenic precautions. These
generally involve a private room with the door to remain closed; limiting visitors; no obviously
infected visitors; no fresh fruit, flowers, or raw vegetables; and no open containers (juices, water,
etc.) which can serve as reservoirs for environmental pathogens.
