The vaccine preventable diseases that are caused by droplet infection are all except

Appeared in: NHM UP Staff Nurse-2021 Shift-1st

Explanation

Polio is the correct answer because it is the exception to the group.
Its primary mode of transmission is the fecal-oral route, involving the ingestion of contaminated food or water.
The poliovirus is an enterovirus, meaning it replicates in the gastrointestinal tract and is shed in feces.
While droplet spread can occur in the acute phase, the fecal-oral route is the main pathway for transmission, distinguishing it from the other options.

Option A: Meningococcal meningitis is incorrect because it is a classic example of a disease spread by respiratory droplets.
Option B: Whooping cough (pertussis) is incorrect as it is a highly contagious respiratory infection transmitted via airborne droplets from coughing and sneezing.
Option C: Diphtheria is incorrect because it is also transmitted from person to person through respiratory droplets.

Clinical Relevance

Nursing practice connection: Knowing Modes of disease transmission for common vaccine-preventable diseases helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
Understanding the mode of transmission is fundamental for nurses to implement appropriate infection control precautions.
For droplet-transmitted diseases like meningitis, diphtheria, and pertussis, Droplet Precautions (surgical mask, patient in a single room) are required in addition to Standard Precautions.
For fecal-oral transmitted diseases like polio, Contact Precautions (gown, gloves) and meticulous hand hygiene are critical, especially after contact with the patient or their environment.

How to Approach the Question

First, identify the keyword 'except'. This tells you that three of the options share a common characteristic, and you must find the one that does not.
The common characteristic mentioned in the stem is 'droplet infection'. Your task is to find the disease that is NOT transmitted by droplets.
Systematically review each option and recall its primary mode of transmission.
Evaluate 'Meningococcal meningitis' - recall it's spread by respiratory secretions (droplets).
Evaluate 'Whooping cough' - recall it's spread by coughing/sneezing (droplets).
Evaluate 'Diphtheria' - recall it's spread by respiratory droplets.

Concept Tested & Keywords

Concept Tested: Modes of disease transmission for common vaccine-preventable diseases.
Stem keywords: vaccine preventable diseases, droplet infection
Lead-in keywords: except
Negative lead-in flag: The question asks for the exception among the options.
