elective hysterectomy
d. A 78-yr-old man admitted to the
medical
unit with complications related
to heart failure
You are caring for a patient B (For treating delirium, the nurse should reduce environmental
who is experiencing delirium stimuli by decreasing noise and light levels.)
due to a lack of sleep. Which
of the following nursing
interventions would be
inappropriate in treating this
patients' condition?
a. You treat the patients'
primary diagnosis that is
causing the delirium.
b. You turn on the lights and a
radio next to the patients' bed
to reorient them.

calendar close to their bed.
Normal Potassium level 3.5-5.0
