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 A
Explanation
Before an X-ray of the abdomen, it is crucial to inquire if the patient is pregnant or potentially pregnant, as ionizing radiation used in X-rays can be harmful to the developing fetus.
b. Fasting for at least 12 hours is not required for an abdominal X-ray, as it is a non-invasive procedure that does not require fasting.
c. Allergic to iodine or shellfish is not directly relevant to an abdominal X-ray, as iodine-based contrast agents are not typically used for this imaging modality.
d. Taking pain medications is not a specific concern for an abdominal X-ray unless there are specific instructions from the healthcare provider regarding medication use before the procedure.
Correct Answer is B
Explanation
After X-ray imaging, it is essential to monitor the patient for any adverse reactions or symptoms that may arise. This helps ensure patient safety and early detection of any potential complications.
a. Providing the patient with a copy of the X-ray images to take home is not a safety measure for post-procedure care. It may be done as part of the patient's records, but monitoring for adverse reactions is more critical for immediate safety.
c. Allowing the patient to leave the facility immediately after the procedure may be appropriate in many cases, but monitoring for adverse reactions is still necessary before discharge.
d. Discontinuing the use of lead aprons and shields after the procedure is not safe. Proper protective equipment should be used until the patient leaves the radiology department to minimize radiation exposure.
