Answer 1

The medication that should be administered prior to having the CT scan for a patient with a known history of an allergic response to IV contrast media is diphenhydramine (Benadryl).

Step-by-step explanation:

The medication that should be administered prior to having the CT scan for a patient with a known history of an allergic response to IV contrast media is diphenhydramine (Benadryl).

Diphenhydramine is an antihistamine that can help prevent histamines released by mast cells from causing allergy symptoms. It works by blocking the effect of histamines, reducing itching, swelling, and other allergic reactions.
