Original practice item, not a recalled exam question. Nothing here is recorded.

Option by option

  • A. Technetium-99m (correct)

    Correct. Technetium-99m is the most appropriate interpretation of the key information.

  • B. Cobalt-60

    Cobalt-60 may be useful in another context but is not supported by this scenario.

  • C. Iodine-131 only

    Iodine-131 only is less appropriate because it does not match the stated nuclear medicine feature.
