Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Hemophilia
Concept:

Blood clotting requires a cascade of specific protein factors. Genetic mutations can impair the synthesis of these proteins.

Solution:

  • Hemophilia is a genetic bleeding disorder that impairs the body's ability to form blood clots.
  • This occurs due to a severe deficiency in specific clotting factors (like Factor VIII in Hemophilia A or Factor IX in Hemophilia B).
  • Individuals with this condition experience prolonged bleeding after injuries.


Why other options are incorrect:

  • Thalassemia: A blood disorder involving decreased production of hemoglobin, affecting oxygen transport, not clotting.
  • Alport's / Coffin-Lowry: Genetic syndromes affecting kidney/hearing and cognitive/physical development, respectively.

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.
