Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Iodine-131


Concept:

Nuclear medicine utilizes the natural metabolic behaviors of the human body to deliver targeted radiation.

Solution:

  • The thyroid gland is the only organ in the body that actively absorbs and stores large quantities of systemic iodine.


  • By giving a patient Iodine-131 (a strong beta and gamma emitter), the radioactive material is automatically funneled directly into the thyroid.


  • This intensely localized radiation efficiently kills thyroid cancer cells while minimizing damage to the rest of the body.


Why other options are incorrect:

Cobalt-60 is used for external beam therapy. Chlorine-36 is an environmental tracer. Radium is a heavy bone-seeker that is highly toxic to the whole body.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
