Final answer:
To avoid neurologic problems after receiving a contrast medium, the nurse should advise the patient to drink at least 1000 to 1500 mL of water to facilitate the elimination of the contrast material through the kidneys.
Step-by-step explanation:
To avoid any neurologic health problems after a procedure involving contrast medium, the best teaching a nurse can provide is: "Drink at least 1000 to 1500 mL of water today." This is because hydration is key to helping the body eliminate the contrast material.
Contrast medium can be processed through the kidneys and excreted in urine. Increased water intake facilitates this process, potentially reducing the risk of contrast-induced nephropathy, a condition where the kidneys experience impaired function due to the contrast material. Ensuring adequate hydration also helps to dilute the contrast medium and promotes its clearance from the body. This is a preventive measure to avoid potential damage or stress to the kidneys, which could lead to neurologic and other health complications.
While the other options provided, such as memory drills, avoiding sunlight, and resting in bed for extended periods, do not directly support the elimination process or protect against potential neurologic health issues associated with the administered contrast medium.
