Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Increased blood pressure
Concept: Oncotic pressure and blood volume regulation.

Solution: Albumin exerts colloid osmotic (oncotic) pressure inside blood vessels. An increase in plasma albumin draws water from interstitial spaces into the intravascular compartment. This expansion of plasma volume raises overall blood volume and leads to increased blood pressure.

Why other options are incorrect:
  • Option A: Heart rate changes depend on autonomic compensation, not direct oncotic force.

  • Option B: Tissue fluid accumulation (edema) occurs when plasma albumin decreases, lowering inward oncotic pull.

  • Option C: Blood pressure rises rather than falls due to intravascular fluid retention.

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.
