Question

if a patient is taking a vasoconstricting drug. what would you expect the blood pressure to do?

Answer 1

Blood pressure is defined as the presdure exerted by the flow of blood on the arterial walls.
Blood pressure is inversely proportional to the diameter of arterial lumen. It means the blood pressure increases when the lumen of artery narrows and decreases when the lumen of artery increases. This is because the narrowing of arterial lumen increases the peripheral vascular resistance thereby increasing the blood pressure.
If a patient is taking vasoconstricting drugs it will result in narrowing of the arterial lumen which will result in increased peripheral resistance and increased blood pressure.
So if a patient is taking a vasoconstricting drug, blood pressure will increase.
