unit with complications related to heart
failure
You are caring for a patient who is B (For treating delirium, the nurse should reduce environmental stimuli by decreasing
experiencing delirium due to a lack of noise and light levels.)
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.
c. You use appropriate touch and verbal
communication to help reorient the patient.
d. You put an easy-to-read clock in the
patients' room and a calendar close to their
bed.
Normal Potassium level 3.5-5.0

adults
Normal cardiac output in adults 4-8 L/min
Normal cardiac index in adults 2.2-4 L/min/m squared
Normal MAP in adults 70-105 mmHg
The action of medication is inotropic when C (Inotropic drugs increase the force of contraction. Preload, not afterload, is
it: decreased. Chronotropic drugs increase heart rate. Treatment of CHF is an indication
A. Decreased afterload for use not an action of inotropic drug.)
B. Increases heart rate
C. Increases the force of contraction
D. Is used to treat CHF
