Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: 7.35
Concept:

Human blood is a heavily regulated buffer system that maintains strict pH homeostasis to prevent enzyme denaturation.

Solution:

  • The normal physiological pH range for human arterial blood is strictly between 7.35 and 7.45.


  • This represents a very slightly basic (alkaline) environment.


  • Option B (7.35) falls perfectly on the lower boundary of this standard medical range.


Why other options are incorrect:

6.62 and 7.33 represent clinical acidosis (fatal if untreated). 7.8 represents severe clinical alkalosis.

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.
