Q

Why should you only assess one carotid artery at a time?

A

If you compress both carotid arteries, you will occlude blood flow to the brain.

Q

How does nicotine increase the risk of heart attack and stroke?

A

Nicotine causes the following: 1. increase in oxygen demand with a concomitant decrease in oxygen supply, 2. an activation of platelets and fibrinogen, 3. and an adverse change in the lipid profile.
