Which type of X-ray imaging is commonly used for evaluating blood vessels and organs in the body?
Plain radiography
Fluoroscopy
Mammography
Magnetic resonance imaging (MRI)
The Correct Answer is B
Fluoroscopy is a type of X-ray imaging that provides real-time moving images of blood vessels and organs in the body. It is commonly used for procedures such as angiography and barium studies.
a. Plain radiography, also known as X-ray radiography, is used to visualize bones and some soft tissues but does not provide real-time moving images like fluoroscopy.
c. Mammography is a specialized type of X-ray imaging used for breast examination, primarily for detecting breast cancer.
d. Magnetic resonance imaging (MRI) uses magnetic fields and radio waves to create detailed images of organs and tissues, but it does not use X-rays for imaging.

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 B
Explanation
Explaining the procedure in simple and age-appropriate language is important when caring for pediatric clients. Describing the need to stay still for the X-ray helps reduce anxiety and fear.
a. "You will be put to sleep during the procedure." This choice is incorrect because sedation or anesthesia is typically not required for a standard X-ray procedure.
c. "You will need to drink a special liquid before the procedure." This choice is incorrect because drinking a special liquid (contrast dye) before the procedure is more common for certain types of X-ray exams, such as those involving the digestive system.
d. "You will need to remove your clothing and put on a hospital gown." This choice is incorrect because wearing a hospital gown is not always necessary for an X-ray procedure. It depends on the area of the body being imaged and the specific instructions provided.
