Explanation

Hand hygiene is the most effective basic technique for preventing and controlling the transmission of infection.
It is a core component of Standard Precautions (Tier One), which are applied universally to all patients in all healthcare settings.
Standard Precautions are based on the principle that all blood, body fluids, secretions, excretions (except sweat), nonintact skin, and mucous membranes may contain transmissible infectious agents.
Contaminated hands of healthcare workers are a primary source of infection transmission in healthcare settings.

Option A: Administering antibiotics is a therapeutic intervention to treat an existing bacterial infection, not a preventative measure to stop the spread of infection from one person to another.
Option B: The use of 'sterile' gloves is incorrect for standard precautions. Clean, non-sterile gloves are used. Sterile gloves are reserved for specific invasive procedures.
Option D: This is an example of a Transmission-Based Precaution (Tier Two), specifically Airborne Precautions. It is not a 'standard' precaution applied to all patients.

Clinical Relevance

Nursing practice connection: Knowing Standard Precautions for Infection Control helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
Consistent practice of hand hygiene is the single most critical factor in preventing healthcare-associated infections (HAIs), which are a major cause of patient morbidity and mortality.
Nurses have a vital role in patient advocacy by modeling correct hand hygiene and reminding other healthcare professionals to do the same, ensuring a culture of safety.
What if? If a patient is diagnosed with Clostridium difficile (C. diff), a spore-forming bacterium, alcohol-based hand rubs are not effective. In this case, hand hygiene must be performed with soap and water to mechanically remove the spores. This is a crucial exception to remember.

How to Approach the Question

First, identify the key term in the question: 'standard precaution'.
Recall that 'standard' implies a universal measure applied to every patient, every time, regardless of their known infection status.
Evaluate each option against this definition of 'universal application'.
Option A (antibiotics) is a treatment, not a universal precaution.
Option B (sterile gloves) is for specific procedures, not all patient contact.
Option D (isolation) is for specific, known/suspected infections, not all patients.
