Which of the following sentences is true regarding concurrent disinfection?

Appeared in: PGICH Noida NO-2025

Explanation

Concurrent disinfection refers to the immediate application of disinfectant measures as soon as infectious materials are discharged from an infected person.
The primary goal is to destroy pathogens as they are released from the body, thereby preventing the ongoing spread of the infectious agent.
This process is continuous throughout the course of the patient's illness.
Examples include disinfecting urine, feces, vomit, contaminated linens, and dressings right after they become soiled.

Option A: This describes terminal disinfection, which is performed after the patient has died.
Option B: This describes terminal disinfection, which is performed after the patient has been discharged.
Option C: This describes terminal disinfection, which is performed after the patient has been transferred to another facility.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Types of Disinfection (Concurrent vs. Terminal) as background academic context rather than a clinical decision trigger.
Concurrent disinfection is a fundamental practice in hospital infection control to break the chain of infection, especially for patients with highly transmissible diseases like C. difficile, MRSA, or norovirus.
Nurses are directly responsible for implementing concurrent disinfection by promptly and safely managing contaminated items and bodily fluids, using appropriate personal protective equipment (PPE) and disinfectants.
What if the patient has a highly contagious airborne disease like tuberculosis? In that case, concurrent disinfection would also involve specialized air handling (negative pressure rooms) and possibly UVGI (Ultraviolet Germicidal Irradiation), in addition to disinfecting surfaces and materials.

How to Approach the Question

First, identify the key term in the question stem, which is 'concurrent disinfection'.
Recall the definition of this term, focusing on the specific timing of the action. 'Concurrent' means happening at the same time or during.
Evaluate each option based on this definition.
Options A, B, and C describe actions that happen after the patient's stay (after death, discharge, or transfer). This timing corresponds to 'terminal' (end) disinfection.
Option D describes an action that happens immediately after infectious material is produced, which is during the patient's illness. This matches the definition of concurrent disinfection.
Therefore, select the option that describes disinfection during the infectious period.
