What Should The Nurse Do To Maintain Standard Precautions

In the intricate world of healthcare, where compassion meets science, nurses stand as frontline guardians, dedicated to healing and safeguarding the well-being of their patients. Central to their practice is the unwavering commitment to infection control, with standard precautions serving as the cornerstone of this crucial aspect of patient care.

This article delves into the comprehensive realm of standard precautions, outlining the essential steps nurses must take to maintain a safe environment for themselves, their patients, and their colleagues. From meticulous hand hygiene to the appropriate use of personal protective equipment (PPE), we will explore each component of standard precautions, elucidating their significance and providing practical guidance for their implementation.

Understanding Standard Precautions

Standard precautions are a set of infection control practices designed to reduce the risk of transmission of microorganisms in healthcare settings. They are based on the principle that all blood, body fluids, secretions, excretions (except sweat), non-intact skin, and mucous membranes may contain transmissible infectious agents.

These precautions apply to all patients, regardless of their diagnosis or presumed infection status. By consistently adhering to standard precautions, nurses can minimize the risk of exposure to infectious agents and prevent the spread of healthcare-associated infections (HAIs).

Key Components of Standard Precautions

Standard precautions encompass a range of practices, each playing a vital role in preventing infection transmission. Let's explore these components in detail:

1. Hand Hygiene: The Foundation of Infection Control

Hand hygiene is arguably the most critical element of standard precautions. Nurses' hands can easily become contaminated with microorganisms during patient care activities, making proper hand hygiene essential to prevent the spread of infection.

• When to Perform Hand Hygiene:

  • Before and after touching a patient.
  • Before donning sterile gloves and after removing them.
  • Before performing an aseptic procedure (e.g., inserting a catheter).
  • After touching blood, body fluids, secretions, excretions, or contaminated items, even if gloves are worn.
  • After removing gloves.
  • Between patient contacts.
  • Before handling medications or preparing food.

• How to Perform Hand Hygiene:

  • Handwashing with Soap and Water: Wet hands with clean, running water. Apply soap and rub hands together vigorously for at least 20 seconds, covering all surfaces, including the backs of hands, wrists, between fingers, and under fingernails. Rinse thoroughly under running water and dry with a clean, disposable towel. Use the towel to turn off the faucet.
  • Using Alcohol-Based Hand Rub: Apply an alcohol-based hand rub (containing 60-95% alcohol) to all surfaces of the hands. Rub hands together until dry, ensuring all surfaces are covered.

2. Personal Protective Equipment (PPE): Creating a Barrier Against Infection

Personal protective equipment (PPE) provides a physical barrier between healthcare workers and potentially infectious materials. The type of PPE used depends on the anticipated exposure risk.

• Gloves: Gloves should be worn whenever there is a potential for contact with blood, body fluids, secretions, excretions, mucous membranes, or non-intact skin.

  • Choose the appropriate type of glove (e.g., sterile, non-sterile, examination, surgical) based on the procedure being performed.
  • Change gloves between tasks and procedures on the same patient if moving from a contaminated body site to a clean one.
  • Remove gloves promptly after use and perform hand hygiene.

• Gowns: Gowns should be worn to protect skin and clothing during procedures and patient care activities where contact with blood, body fluids, secretions, or excretions is anticipated.

  • Choose a gown that is appropriate for the amount of fluid exposure anticipated.
  • Remove the gown promptly after use and perform hand hygiene.

• Masks and Respirators: Masks and respirators protect the nose and mouth from splashes, sprays, and respiratory droplets.

  • Surgical masks should be worn during procedures that may generate splashes or sprays of blood or body fluids.
  • Respirators (e.g., N95 respirators) should be worn during procedures that may generate aerosols containing infectious agents, such as during the care of patients with suspected or confirmed airborne infections (e.g., tuberculosis, measles, chickenpox). Fit testing is required for respirators to ensure a proper seal.

• Eye Protection (Goggles or Face Shields): Eye protection should be worn during procedures that may generate splashes or sprays of blood or body fluids.

3. Respiratory Hygiene/Cough Etiquette: Preventing the Spread of Respiratory Infections

Respiratory hygiene/cough etiquette aims to prevent the transmission of respiratory infections.

• Cover your mouth and nose with a tissue when coughing or sneezing. If a tissue is not available, cough or sneeze into your upper sleeve or elbow, not your hands.
• Dispose of used tissues in a no-touch waste receptacle.
• Perform hand hygiene after coughing, sneezing, or touching respiratory secretions.
• Offer masks to patients and visitors who are coughing or sneezing.
• Maintain spatial separation of at least 3 feet from others if possible, especially if you have respiratory symptoms.

4. Safe Injection Practices: Preventing Bloodborne Infections

Safe injection practices are essential to prevent the transmission of bloodborne infections, such as hepatitis B, hepatitis C, and HIV.

• Use a new sterile syringe and needle for each injection.
• Never reuse syringes or needles on multiple patients, even if the needle is changed.
• Use single-dose vials whenever possible.
• If using multi-dose vials, clean the vial's rubber stopper with alcohol before each use.
• Do not enter a multi-dose vial with a used syringe or needle.
• Use aseptic technique when preparing and administering injections.
• Dispose of used needles and syringes immediately in a sharps container.

5. Safe Handling of Contaminated Equipment and Sharps: Preventing Injuries and Infections

Safe handling of contaminated equipment and sharps is crucial to prevent injuries and the transmission of bloodborne infections.

• Handle used sharps with care to prevent needlestick injuries.
• Do not recap, bend, or break used needles.
• Dispose of used needles and other sharps immediately in a puncture-resistant sharps container.
• Transport contaminated equipment in a leak-proof container.
• Clean and disinfect or sterilize reusable equipment according to established protocols.

6. Environmental Cleaning and Disinfection: Maintaining a Clean and Safe Environment

Environmental cleaning and disinfection are essential to remove microorganisms from surfaces and prevent their spread.

• Clean and disinfect frequently touched surfaces (e.g., bed rails, doorknobs, light switches) regularly.
• Use EPA-registered disinfectants according to the manufacturer's instructions.
• Follow established protocols for cleaning and disinfecting spills of blood or body fluids.

7. Waste Management: Safely Disposing of Contaminated Materials

Proper waste management is necessary to prevent the spread of infection from contaminated materials.

• Dispose of infectious waste (e.g., blood-soaked dressings, used sharps) in designated containers.
• Follow local regulations for the disposal of hazardous waste.
