115
Q

When would a patient take nitroglycerin?

A

A patient experiencing angina, MI (given IV), or suffering from chronic heart failure.

116
Q

How do nitrates work?

A

Nitrates lower blood pressure which improves blood flow to the myocardium.

117
Q

When a patient is having an angina episode, what is the protocol for taking sublingual nitroglycerin?
