Standard precautions serve as the foundational infection control practices designed to minimize pathogen transmission in healthcare settings. These measures apply universally to every patient, regardless of their confirmed or suspected infection status. Blood, body fluids, secretions, and excretions all carry potential infectious agents like HIV, Hepatitis B, and Hepatitis C. Treating every patient interaction with the same baseline protective barrier prevents cross-contamination between patients and shields healthcare workers from occupational exposure.
Hand hygiene remains the single most effective intervention for interrupting the chain of infection.
Friction mechanical action dislodges transient microorganisms accumulated during routine patient contact.
Personal protective equipment (PPE) creates a physical barrier between the healthcare worker and potential infectious materials. Selecting the correct item depends entirely on the anticipated mode of transmission during a specific nursing procedure.
Donning follows a strict logical sequence—gown first, then mask or respirator, eye protection, and gloves last. Removal requires an equally deliberate sequence to prevent self-contamination, starting with gloves and ending with respiratory protection.
Sharps injuries pose a severe occupational risk for transmission of bloodborne viruses like hepatitis and HIV. Safe injection practices demand that needles and syringes are single-use devices, never to be reused for another patient, even if the needle is changed. Medication vials designated as single-dose should never be pooled or saved for subsequent patients.
Needles must never be recapped using a two-handed technique. When safety devices are unavailable, nurses use a one-hand scoop method or immediately drop the uncapped sharp into a puncture-resistant container located at the point of use. Sharps containers must be sealed and replaced before reaching the designated fill line to prevent needlestick injuries from overflowing waste.
Respiratory hygiene targets the containment of respiratory secretions to prevent droplet transmission of pathogens like influenza, SARS-CoV-2, and Mycobacterium tuberculosis. Patients, visitors, and staff must cover their mouths and noses with a tissue when coughing or sneezing, followed by immediate disposal of the used tissue in a waste receptacle. When tissues are unavailable, coughing into the upper sleeve or inner elbow prevents hand contamination. Healthcare facilities provide accessible hand sanitizer stations, tissues, and no-touch waste bins at entrances alongside clear signage instructing individuals with respiratory symptoms to wear masks.
Patient care equipment and hospital surfaces frequently act as fomites, harboring infectious organisms between contacts. Reusable medical devices, such as blood pressure cuffs, glucometers, and stethoscopes, require thorough cleaning and disinfection between each patient use. Cleaning removes organic soil that can deactivate chemical disinfectants, while disinfection eliminates pathogenic microorganisms. High-touch surfaces in patient rooms, including bed rails, call buttons, and bedside tables, undergo scheduled terminal cleaning using hospital-approved disinfectants with documented contact times.
Despite rigorous preventative measures, accidental needle sticks, mucous membrane splashes, and body fluid spills occur in clinical environments. Immediate management of an occupational exposure involves washing percutaneous wounds with soap and water, flushing mucous membranes with copious amounts of clean water, and reporting the incident immediately to occupational health services. Blood and body fluid spills on environmental surfaces require prompt containment, application of absorbent material, cleaning of visible debris, and disinfection with a calibrated chlorine solution or other facility-approved hospital disinfectant.
