What is a radiopharmaceutical?
AA drug that removes all radioactivity from the body
BA vitamin supplement given before an X-ray
CA type of anesthetic used during surgery
DA tagged compound with a radioactive nuclide
Answer & Solution
Correct answer: D. A tagged compound with a radioactive nuclide
1. A compound is called tagged once a radioactive nuclide has been incorporated into it for a specific purpose.
2. A tagged compound used for medical purposes is called a radiopharmaceutical.
3. It does not remove radioactivity from the body, and it is not a vitamin or an anesthetic.
4. So a tagged, radioactive compound used for medical imaging is correct.
