Which is a key step in aseptic technique?

• A. Hand hygiene
• B. Reading patient chart
• C. Administering antibiotics
• D. Checking vital signs

Answer: (A)

Preventing contamination hinges on hands being clean. Hand hygiene is the foundational step in aseptic technique because hands are the primary way microbes are transferred to sterile fields, wounds, injections, catheters, and equipment. Cleaning hands effectively—whether by thorough handwashing with soap and water or by using an appropriate alcohol-based hand rub—dramatically reduces the microbial load and lowers infection risk. Good practice includes cleaning under the nails, keeping nails short, and applying the sanitizer for the recommended duration, plus performing hand hygiene before touching the patient, before any sterile or invasive procedure, after potential exposure to contaminants, and after removing gloves. Reading a patient chart, administering antibiotics, and checking vital signs are important parts of patient care, but they do not establish or maintain asepsis. They support treatment and monitoring but don’t directly prevent contamination during procedures.
