A patient scheduled for an X-ray of the chest should be educated to:
Refrain from eating or drinking for 24 hours before the procedure.
Wear loose-fitting clothing that does not contain any metal.
Lie still on the X-ray table to prevent motion artifacts.
Empty the bladder before the procedure.
The Correct Answer is B
For an X-ray of the chest, the patient should wear loose-fitting clothing that does not contain any metal, such as zippers, buttons, or jewelry, to avoid interference with the X-ray image and ensure optimal visualization of the chest.
a. Refraining from eating or drinking for 24 hours before the procedure is not necessary for a chest X-ray, as it is a non-invasive procedure that does not require fasting.
c. While it is essential for the patient to lie still during the X-ray, this instruction is not specific to a chest X-ray; it applies to all X-ray procedures to prevent motion artifacts.
d. Emptying the bladder is not required for a chest X-ray, as the bladder is not in the field of view for this particular imaging procedure.

Before an X-ray of the lower extremities, the patient should be instructed to remove any metal objects, such as jewelry, piercings, or metallic accessories, from the lower limbs to prevent artifacts on the X-ray image.
a. While the patient may be required to remove clothing covering the lower extremities, it is not necessary for them to wear a hospital gown for the procedure.
c. Applying a topical anesthetic is not routinely done for X-ray imaging, as X-rays are non-invasive and do not require anesthesia.
d. Refraining from bearing weight on the lower extremities is not a standard preparation for X-ray imaging of the lower limbs unless specifically instructed by the healthcare provider for certain conditions.
Correct Answer is A
Explanation
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.
