Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: 101325
Concept:

Standard atmospheric pressure at sea level is a constant physical property that can be expressed in various equivalent units.

Solution:

  • By definition, \( 1 \text{ atmosphere (atm)} \) is exactly equivalent to \( 760 \text{ torr} \) (or \( 760 \text{ mmHg} \)).


  • In the International System of Units (SI), pressure is measured in Pascals (\( \text{Pa} \)).


  • The conversion factor dictates that \( 1 \text{ atm} = 101,325 \text{ Pa} \).


  • Therefore, \( 760 \text{ torr} = 101,325 \text{ Pa} \).


Why other options are incorrect:

1 is the value in atm. 76 is the value in cmHg. 760 is the value in mmHg. Only 101325 represents Pascals.

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.
