What is a basic component of standard precautions?

• A. Hand hygiene
• B. Gloves for all contact with patients
• C. Mask for all patient interactions
• D. Use of N95 respirator for all patients

Answer: (A)

Hand hygiene is the foundation of standard precautions because it directly stops the most common way infections spread—through hands. In practice, you clean your hands before touching a patient, before performing any clean or aseptic task, after exposure to body fluids, after touching a patient, after touching the patient’s surroundings, and after removing gloves. Using soap and water when hands are visibly dirty and an alcohol-based hand rub otherwise makes this step quick and effective, dramatically reducing the transmission of pathogens in any care setting.

Gloves are worn when there is potential contact with blood, body fluids, mucous membranes, or such materials, but the need for gloves doesn’t replace the need for hand hygiene. Masks and N95 respirators are used based on the risk of exposure to droplets or airborne particles, not for every patient. So, hand hygiene stands out as the essential, universal practice in standard precautions.
