When preparing a patient for an X-ray of the lower extremities, the nurse should ask the patient to:
Remove all clothing and wear a hospital gown.
Remove any metal objects from the lower extremities.
Apply a topical anesthetic to the area to be imaged.
Refrain from bearing weight on the lower extremities.
The Correct Answer is B
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
Wearing a lead apron is essential to protect both the patient and the healthcare provider from unnecessary exposure to ionizing radiation during X-ray imaging. The lead apron serves as a barrier that absorbs and reduces the amount of radiation reaching the individual wearing it.
b. Using high doses of X-rays for better image quality is not a safe practice. X-ray imaging should be performed using the lowest dose of radiation necessary to obtain diagnostic images while still maintaining image quality.
c. Standing close to the X-ray machine during image capture can lead to increased radiation exposure for the healthcare provider. They should maintain a safe distance from the X-ray source during the procedure.
d. Taking X-ray images without any protective measures is unsafe and increases the risk of radiation exposure to both the patient and the healthcare provider.
Correct Answer is D
Explanation
X-ray imaging uses ionizing radiation, which has high energy and can penetrate tissues. When X-rays pass through the body, they are absorbed differently by various tissues, creating an image that allows visualization of bones and soft tissues.
a. Using sound waves to create images of internal structures refers to ultrasound imaging, not X-ray imaging.
b. Utilizing magnetic fields to visualize bones and soft tissues describes magnetic resonance imaging (MRI), not X-ray imaging.
d. Emitting radio waves to visualize organs and blood vessels is a principle of MRI and not X-ray imaging.
