A patient with angina is receiving Nitroglycerin and begins to complain of a severe headache. What is the most appropriate response from the nurse?

Headaches can occur due to the vasoconstriction effect of the medication.

I can give you some Morphine to help with that headache.

I will notify the physician immediately.

This is a normal side effect of Nitroglycerin as it dilates your body's vessels.
