Question 1

Mean arterial pressure will be increased
by
A. Increased stroke volume
B. Bradycardia
C. Decreased stroke volume
D. Reduced venous return
E. Relaxation of arterioles

Answer 1

A

Question 2

What is bradycardia

Answer 2

Low heart rate

Question 3

What will happen to the Mean arterial pressure if stroke volume is decreased?

Answer 3

Decreased stroke volume results in reduced Blood pressure

Question 4

The activation of the sympathetic nervous system will
A. Decrease heart rate

E. Increase cardiac output

Answer 4

E

Question 5

D. A decrease in blood volume
E. An increase in blood volume

Answer 5

D

Question 6

Blood pressure is determined by
A. Heart rate multiplied by cardiac output
B. Cardiac output multiplied by total peripheral resistance
C. Heartrate multiplied by stroke volume
