Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Passive immunity
Concept:

Immunity can be categorized by how it is acquired (natural vs. artificial) and whether the host makes their own response (active vs. passive).

Formula:

None

Solution:

  • When pre-formed antibodies (like antivenom or antiserum) are injected into a patient, the patient's immune system does not do the work of creating them.


  • Because the body is passively receiving external defense molecules, this is defined as passive immunity (specifically, artificial passive immunity).


  • This provides immediate, but short-lived, protection.


Why other options are incorrect:

  • Active immunity: Occurs when the host's own B and T cells generate a response (e.g., getting a vaccine or catching a disease).

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.
