Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Myxedema
Concept:

Thyroid hormones are the body's metabolic engine. A lack of these hormones drastically slows down all cellular processes.

Solution:

  • Severe hypothyroidism in an adult is clinically termed Myxedema.


  • Without thyroxine, the metabolic rate crashes. The body accumulates mucopolysaccharides under the skin, which trap water and create a distinct puffy appearance (especially around the eyes), accompanied by lethargy and dry skin.


Why other options are incorrect:

Cretinism is hypothyroidism in infants (causing dwarfism and retardation). Cushing's and Addison's relate to adrenal cortisol imbalances, not primary metabolic crash.

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.
