You Selected:
well the body reacts to controlled exercise stress.
Correct response:
well the body reacts to controlled exercise stress.
Explanation:
Graded exercise testing is a diagnostic and prognostic tool used to determine the
physiologic responses to controlled exercise stress. Information gained from a
graded exercise test can achieve diagnostic, functional, and therapeutic objectives
for the client. Graded exercise tests involve the use of a treadmill, stationary
bicycle, or arm ergometry. The information obtained from this test is not used to
set the incline on the treadmill, and measuring the distance walked and the
duration of the walk are not the purpose of a graded exercise test.
Remediation:
Electrocardiography, exercise

A nurse should include which discharge instruction for clients receiving tricyclic
antidepressants?
You Selected:

treatment with tricyclic antidepressants. Safe use of tricyclic antidepressants during
pregnancy and breast-feeding hasn't been established.

Amitriptyline hydrochloride
Clomipramine hydrochloride
