Answer to Question 1

Ans:
C

Feedback:

Shivering is a response to a signal for increased heat production. It would only occur on a hot day if the set point for temperature regulation were increased, as in the case of fever but not hyperthermia. Moist skin, cognitive changes, and dizziness can occur with either fever or hyperthermia.

Answer to Question 2

Ans:
C

Feedback:

Bicycle or treadmill ergometry measures heart rate, and other responses during exercise. Echocardiograms for EF, TE echocardiograms, and blood gas analysis are not performed in the rehab setting.
