Hypertension and Blood Pressure Quiz

What two factors are multiplied to calculate cardiac output?

• Heart rate and blood pressure

• Stroke volume and heart rate

• Peripheral resistance and stroke volume

• Blood volume and heart rate

Which factor primarily contributes to increased blood pressure in hypertension?

• Reduced heart rate

• Increased peripheral resistance

• Lower blood volume

• Decreased cardiac output

What happens to the arteries when there is increased sympathetic activity?

• They constrict, increasing peripheral resistance

• They dilate, reducing blood pressure

• They remain unchanged

• They become more elastic

What is the role of the renin-angiotensin system in blood pressure regulation?

• It reduces cardiac output

• It increases vasoconstriction

• It increases vasodilation

• It decreases blood volume

What enzyme converts Angiotensin I to Angiotensin II?

• Renin

• Norepinephrine

• Aldosterone

• ACE (Angiotensin Converting Enzyme)

How does aldosterone affect sodium and water reabsorption?

• It decreases sodium reabsorption

• It increases sodium and water reabsorption

• It only affects water reabsorption

• It has no effect on reabsorption

What is the consequence of increased blood volume on cardiac output?

• Decreased heart rate

• No change in cardiac output

• Increased cardiac output

• Decreased cardiac output

Why is hypertension considered a self-perpetuating cycle?

• It stabilizes blood flow to the kidneys

• It reduces peripheral resistance

• It causes continuous damage to blood vessels

• It decreases blood pressure over time

What is the main function of the kidneys in relation to blood pressure?

• To increase blood pressure

• To filter blood and regulate fluid balance

• To decrease cardiac output

• To produce adrenaline

What is a potential intervention point to manage hypertension?

• Blocking renin release

• Reducing peripheral resistance

• Enhancing sympathetic activity

• Increasing blood volume
