Item23 Time Remaining 48 minutes 12 seconds00:48:12Item 23 Time Remaining 48 minutes 12 seconds00:48:12An increase in which of these would produce an increase in mean arterial pressure?Multiple ChoicePeripheral resistanceHeart rateStroke volumeBoth "Heart rate" and "Stroke volume" are correct.All of the choices are correct.
Solution
All of the choices are correct. An increase in peripheral resistance, heart rate, or stroke volume would all lead to an increase in mean arterial pressure. This is because mean arterial pressure is determined by cardiac output (which is a product of heart rate and stroke volume) and peripheral resistance. Therefore, an increase in any of these factors would increase mean arterial pressure.
