Explanation

Handwashing is the most critical action to stop the spread of infections in hospitals.
It breaks the chain of infection by removing pathogens that can be transferred from one patient to another, or from the environment to a patient, via the hands of healthcare workers.
This transmission between patients, staff, and the environment is known as cross-infection.
Preventing cross-infection is the primary strategy to reduce healthcare-associated infections (HAIs), a major risk to patient safety.

Option A: While dust can contain microorganisms, it is not the primary mode of transmission for most hospital infections. The main routes are direct and indirect contact.
Option B: Preventing infection in the healthcare worker is an important secondary benefit, but the primary ethical and safety obligation is to prevent the transmission of pathogens to and between vulnerable patients.
Option D: This is unrelated to the principles of hygiene, infection control, or patient safety. Clinical decisions should be based on safety and efficacy, not material costs.

Clinical Relevance

Nursing practice connection: Safe nursing care depends on performing Principles of infection control and hand hygiene in a hospital setting in the correct sequence, documenting the action clearly, and monitoring for the expected response.
Hand hygiene is the cornerstone of preventing healthcare-associated infections (HAIs), which increase patient morbidity, mortality, and healthcare costs.
Strict adherence to hand hygiene protocols is essential to combat the spread of multidrug-resistant organisms (MDROs) like Methicillin-resistant Staphylococcus aureus (MRSA) and Vancomycin-resistant Enterococci (VRE).
What if? If a patient is known to have a Clostridioides difficile (C. diff) infection, alcohol-based hand rubs are ineffective against its spores. The nurse MUST wash their hands with soap and water to mechanically remove the spores.

How to Approach the Question

First, identify the core concept of the question. It asks for the primary reason for a fundamental safety procedure (handwashing) in a specific setting (a hospital).
Analyze the context of a hospital: it's an environment with many vulnerable individuals (patients) and multiple sources of infection.
The main goal of infection control in such a setting is to prevent the spread of pathogens between these individuals and from the environment.
Evaluate each option based on this primary goal.
Option C, 'To Prevent Cross Infection,' directly describes the process of spreading infection between people in a hospital, making it the most accurate and comprehensive answer.
Recognize that other options are either secondary benefits (preventing self-infection) or irrelevant (dust, economy).
