What factor can increase blood pressure?
An increase in parasympathetic stimulation
A decrease in peripheral resistance
An increase in heart rate
A decrease in stroke volume
The Correct Answer is C
A. An increase in parasympathetic stimulation: Parasympathetic activity lowers heart rate and typically reduces BP, so this would not increase BP.
B. A decrease in peripheral resistance: Lower peripheral resistance reduces BP (BP = CO × PR), so this would decrease BP.
C. An increase in heart rate: Raises cardiac output (if stroke volume is similar), which tends to increase blood pressure.
D. A decrease in stroke volume: Lowers cardiac output and therefore tends to decrease BP.
