2. What is the name of the radioactive isotope commonly used in medical imaging techniques like PET scans?

• A. Uranium-235
• B. Plutonium-239
• C. Potassium-40
• D. Fluorine-18

Correct answer: D

Rationale: Fluorine-18 is the radioactive isotope commonly used in medical imaging techniques like PET scans. It is often used in the form of fluorodeoxyglucose (FDG) to detect areas of increased metabolic activity in the body, such as in cancer cells. Uranium-235 and Plutonium-239 are not typically used in medical imaging, and Potassium-40 is a naturally occurring radioactive isotope found in the human body but is not commonly used in medical imaging techniques.

3. Calcitonin, a hormone that helps regulate calcium levels, is produced by the:

• A. Thyroid gland
• B. Parathyroid gland
• C. Thymus gland
• D. Adrenal gland

Correct answer: A

Rationale: The correct answer is A: "Thyroid gland." Calcitonin is a hormone produced by the thyroid gland that helps regulate calcium levels in the body. It works in opposition to parathyroid hormone, which is produced by the parathyroid gland. The thymus gland is responsible for immune function, while the adrenal gland produces hormones like cortisol and adrenaline. Therefore, the thyroid gland is the specific gland responsible for producing calcitonin to regulate calcium levels in the body.
