Question

A patient demonstrates diffuse urticaria shortly after the intravenous administration of iodinated contrast media. Correct treatment would include:

A. administration of an adrenergic drug.
B. administration of IV fluids.
C. oxygen at 3 to 4 L/min.
D. administration of an antihistamine drug.

Answer 1

For a patient with diffuse urticaria after receiving iodinated contrast media, the correct treatment includes the administration of an antihistamine drug to counteract the allergic reaction.

Step-by-step explanation:

A patient exhibiting diffuse urticaria, a type of hypersensitivity reaction often associated with allergic responses, shortly after the intravenous administration of iodinated contrast media should be treated with the administration of an antihistamine drug. Antihistamines work by blocking the action of histamine, a compound released during allergic reactions, thereby providing relief from symptoms such as hives. In more severe cases, additional treatments such as adrenergic drugs (e.g., epinephrine), oxygen therapy, or intravenous fluids might be necessary depending on the patient's condition and symptoms.
