Explanation

Hand washing is the most effective basic technique in preventing and controlling the transmission of infection in healthcare settings.
The primary purpose of washing hands before a procedure is to prevent cross-infection, which is the transfer of pathogens from the healthcare worker or environment to the patient.
This practice is a fundamental component of medical asepsis and standard precautions, designed to protect the patient from healthcare-associated infections (HAIs).
It directly corresponds to the WHO's '5 Moments for Hand Hygiene,' specifically 'Moment 2: Before a clean/aseptic procedure'.

Option A: While hand washing does remove dirt and dust, the primary clinical reason is to remove pathogenic microorganisms, which are a much more significant threat than simple dust.
Option B: The question specifies hand washing before a procedure, where the primary focus is on protecting the patient. Preventing self-infection is the main goal of hand washing after patient contact or after exposure to body fluids.
Option D: This option is unrelated to the clinical and safety principles of infection control. Patient safety and prevention of infection always take priority over material costs.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Infection Control and Hand Hygiene as background academic context rather than a clinical decision trigger.
Adherence to hand hygiene protocols is a non-negotiable standard of nursing practice and a key performance indicator for hospital safety and quality.
Failure to perform hand hygiene is a leading cause of preventable healthcare-associated infections (HAIs), which increase patient morbidity, mortality, and healthcare costs.
What if the procedure is non-invasive, like taking a blood pressure reading? The answer remains the same. Hand hygiene is required before any direct patient contact (Moment 1) and after (Moment 4), not just for invasive procedures, to prevent the spread of microorganisms.

How to Approach the Question

First, identify the core concept of the question, which is infection control.
Analyze the specific action and timing: 'Hand washing' and 'before doing any procedure'. The timing 'before' is a key clue, indicating the action is to protect the patient.
Evaluate each option in the context of protecting the patient. 'Cross-infection' directly addresses the transfer of germs to the patient.
Consider the other options. 'Self-infection' relates to protecting the provider, which is more relevant after a procedure. 'Dust' is too general, and 'economy' is irrelevant to safety.
Select the option that best describes the primary, patient-centered reason for the action.
