Final answer:
The nurse should monitor for increased blood pressure and chest pain after the administration of sumatriptan.
Step-by-step explanation:
The Correct Answer is:
d) increased blood pressure; chest pain.
After the administration of sumatriptan, a medication used to treat migraine headaches, the nurse should monitor for increased blood pressure and chest pain. Sumatriptan is a vasoconstrictor, which means it narrows blood vessels, and it can lead to increased blood pressure. Chest pain can be a side effect of the medication as well.
