Question

MRI technologists take precautions by

protecting themselves from diseased tissue.

covering parts of the body not being tested with lead-lined blankets.

ensuring a patient is not wearing metal.

monitoring the patient's physical appearance, heart rate, skin temperature, and blood oxygen.

Answer 1

Correct: 1, 3, and 4. Incorrect: 2.

Brief explanations:
- Protecting themselves from diseased tissue: yes — MRI technologists follow standard/universal precautions (gloves, gowns, hand hygiene, etc.) when there is exposure risk to blood or body fluids.
- Ensuring a patient is not wearing metal: yes — checking for and removing external metal (jewelry, piercings, clothing with metallic components) and screening for implants/foreign bodies is essential for safety in the magnetic field.
- Monitoring the patient’s appearance, heart rate, skin temperature, and oxygen saturation: yes — techs continuously observe the patient (visual/intercom), and use physiologic monitoring (pulse/SpO2, sometimes ECG/capnography, skin/temp monitoring as indicated) especially for sedated or high‑risk patients.
- Covering parts with lead‑lined blankets: no — lead shielding is used for ionizing radiation (x‑ray/CT/fluoroscopy), not for MRI. Blankets for warmth may be used, but they are not lead‑lined and provide no MRI safety benefit.
