4. "Diltiazem (Cardizem) releases Substance P, activating pain receptors in your brain and giving you the headache."

Answer 1

Diltiazem (Cardizem) causes the blood vessels in the brain to widen, resulting in a headache.

Step-by-step explanation:

The best response by the nurse is option 2: "Diltiazem (Cardizem) causes the blood vessels in your brain to widen; giving you the headache."

Diltiazem is a calcium channel blocker that works by relaxing and widening blood vessels. This can lead to a headache as a side effect. The dilation of blood vessels in the brain can cause increased blood flow and pressure, resulting in a headache.

It is important for the client to know that headaches are a potential side effect of the medication, and if the headache becomes severe or persistent, they should consult their healthcare provider.
