Answer to Question 1

C
Feedback:
The reninangiotensinald osterone system is initiated in response to changes in blood volume, so that a decrease in blood pressure would be most likely to initiate this system. An increase in temperature, a decrease in pulse, and a pain level of 3 would not affect blood volume.

Answer to Question 2

C
Feedback:
Normal dosage range is 25 to 100 mg so the nurse should not be concerned unless the dosage exceeded 100 mg.
