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.

Pediatric patients are more sensitive to the effects of ionizing radiation compared to adults. Therefore, using a lower radiation dose is essential to minimize the potential long-term risks associated with radiation exposure in pediatric populations.
a. The thickness of bones is not the primary factor for using lower radiation doses in pediatric patients. The decision is based on their increased sensitivity to radiation.
c. Lowering the radiation dose in pediatric patients may compromise image quality to some extent, but the primary reason is to reduce radiation exposure to these vulnerable populations.
d. While the size of pediatric patients may influence radiation dose adjustments, the main concern is their increased radiation sensitivity rather than physical size.
