Answer to Question 1

Ans: D
The elasticity and resistance of the walls of the arterioles help to maintain normal blood pressure. With aging, the walls of arterioles become less elastic, which interferes with their ability to stretch and dilate, contributing to a rising pressure within the vascular system. This is reflected in an increased blood pressure.

Answer to Question 2

Ans: B
Because inserting the thermometer into the rectum can slow the heart rate by stimulating the vagus nerve, assessing a rectal temperature may not be allowed for clients after cardiac surgery.
