How can the healthcare provider reduce the risk of radiation exposure during fluoroscopy procedures?
Limiting the use of image intensifiers to reduce X-ray scatter.
Increasing the fluoroscopy time for better visualization.
Standing closer to the patient during the procedure.
Using the highest possible radiation dose for accurate images.
The Correct Answer is A
Image intensifiers are used in fluoroscopy to enhance image brightness and quality. Limiting their use can help reduce X-ray scatter and unnecessary radiation exposure to the patient and healthcare provider.
b. Increasing the fluoroscopy time should be avoided to minimize radiation exposure to the patient and provider. The goal is to keep fluoroscopy time as short as possible while still obtaining necessary images.
c. Standing closer to the patient during the procedure increases the radiation exposure to the healthcare provider. Providers should maintain a safe distance from the X-ray source during fluoroscopy.
d. Using the highest possible radiation dose is not recommended, as the goal is to use the lowest radiation dose necessary to obtain diagnostic images while still maintaining image quality and reducing the risk of radiation exposure to the patient and provider.

Correct Answer is B
Explanation
Before obtaining X-ray images, the patient should be instructed to remove any jewelry and metallic objects from the body, as they can interfere with the X-ray image and cause artifacts.
a. Personal identification documents are not required to be removed for X-ray imaging, as they do not interfere with the procedure or image quality.
c. Prescription medications taken on the day of the procedure do not need to be removed, as they are not related to the X-ray imaging process.
d. Clothing worn on the upper body may need to be adjusted or removed, depending on the area being imaged, but it is not necessary for the patient to completely remove all clothing.
Correct Answer is A
Explanation
Metal objects, including jewelry and accessories, can interfere with the X-ray image quality. Instructing the client to remove these items ensures accurate results.
b. "Consume a full meal before the procedure." This choice is incorrect because clients are usually instructed to fast for a specific period before an X-ray, especially if abdominal imaging is involved, to reduce interference with image quality due to food and gas.
c. "Drink a large amount of water before the procedure." This choice is incorrect because drinking water is typically not required before an X-ray procedure. Fasting or specific preparation instructions are more commonly given.
d. "Avoid taking any pain medications before the procedure." This choice is incorrect because the nurse does not typically instruct the client to avoid pain medications before an X-ray. Pain medications would not interfere with the X-ray procedure itself.
