X-ray imaging is based on the principle of:
Using sound waves to create images of internal structures.
Utilizing magnetic fields to visualize bones and soft tissues.
Utilizing ionizing radiation to penetrate tissues and create images.
Emitting radio waves to visualize organs and blood vessels.
The Correct Answer is D
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.

Correct Answer is C
Explanation
When performing X-rays on pregnant patients, it is essential to use lead aprons to cover the abdomen and pelvic area to protect the developing fetus from unnecessary radiation exposure.
a. Setting the X-ray machine to maximum power is not safe for any patient, including pregnant individuals. The radiation dose should be minimized while maintaining image quality.
b. While X-rays during pregnancy should be used judiciously and only if medically necessary, avoiding X-rays during the entire first trimester is not practical in emergencies or urgent diagnostic situations.
d. Providing a lead apron only to the patient and not to the healthcare provider can result in increased radiation exposure to the provider, who should also wear protective equipment during the procedure.
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.
