Final answer:
A medical assistant should obtain information about allergies, previous reactions to contrast agents, medical conditions, and medications when a patient is having an X-ray with contrast.
Step-by-step explanation:
When obtaining information from a patient who is having an X-ray with contrast, a medical assistant should ask about any allergies the patient may have. This is important because some contrast agents contain iodine, and patients with iodine allergies may have an allergic reaction. The medical assistant should also ask about any previous adverse reactions to contrast agents, as well as any medical conditions that may increase the risk of complications.
For example, if the patient has kidney disease, it may be necessary to take special precautions or use a different type of contrast agent. Additionally, the medical assistant should inquire about medications the patient is currently taking, particularly those that may interact with the contrast agent or increase the risk of side effects.
Overall, the goal is to gather relevant medical history and ensure the patient's safety during the procedure.
