Hand Hygiene, Standard Precautions, PPE and Sterile Technique
- Differentiate between routine hand hygiene methods and identify the key moments when hand hygiene must be performed.
- Apply standard precautions, including appropriate personal protective equipment selection, donning and doffing sequences, and safe sharps handling within the LPN/VN scope.
- Implement the principles of sterile technique to maintain a sterile field, handle solutions safely, and recognize actions that cause contamination.
Principles and Execution of Effective Hand Hygiene
Hand hygiene is the single most effective intervention to prevent healthcare-associated infections. Practical nurses encounter microorganisms continuously during daily client care. Practicing consistent and correct hand cleaning is the foundation of keeping clients and staff safe. Healthcare workers should keep their natural nails trimmed short, clean, and free of artificial nails to prevent harboring pathogens beneath the nail tips.
Alcohol-based hand rub is preferred for routine hand hygiene when hands are not visibly soiled. It is quick and convenient between routine tasks. However, hands must be washed with soap and water when visibly soiled with dirt, blood, or body fluids. Soap and water must also be used for hand hygiene after caring for clients with spore-forming organisms such as Clostridioides difficile, because alcohol-based rubs do not effectively kill these spores.
When washing hands with soap and water, scrub all hand surfaces for at least 20 seconds. Hands must be rinsed with water running downward toward the fingertips to wash away microorganisms into the sink basin rather than back up the forearms. If the faucet is hand-operated, turn it off with a clean paper towel after drying to avoid recontaminating clean hands.
The practical nurse must know exactly when to perform hand hygiene throughout the shift. Clean hands before touching a client and before beginning a clean or aseptic procedure. Hand hygiene must also be performed after any body fluid exposure risk, after touching a client, and after touching objects in the client's immediate surroundings, such as overbed tables or bedrails.
| Clinical Situation | Required Cleaning Method | Key Technique Rules |
|---|---|---|
| Routine care without visible soil on hands | Alcohol-based hand rub | Rub product over all surfaces until hands are completely dry. |
| Hands visibly soiled with dirt, blood, or body fluids | Soap and water | Scrub all surfaces for at least 20 seconds; rinse downward toward fingertips. |
| Care of a client with spore-forming organisms (Clostridioides difficile) | Soap and water | Friction and flowing water physically wash spores away; turn off hand-operated faucet with a paper towel. |
Common mistakes
- Using an alcohol-based hand rub after providing care to a client with Clostridioides difficile instead of washing with soap and water to physically remove spores.
- Recapping a used needle using a two-handed method instead of immediately disposing of the intact needle into a designated puncture-resistant sharps container.
- Turning away from or lowering hands below waist level during a sterile procedure, which immediately contaminates sterile items.
- Attempting to salvage or wipe down a sterile drape that has become wet, rather than recognizing strike-through contamination and setting up a brand-new sterile field.
Key points
- Hand hygiene is the single most effective intervention to prevent healthcare-associated infections, using alcohol-based rub for routine care and soap and water for visible dirt, body fluids, or spore-forming pathogens like C. difficile.
- Standard precautions apply to all clients and protect against blood, non-intact skin, mucous membranes, secretions, and body fluids (excluding sweat).
- PPE donning follows the order of gown, mask/respirator, goggles/face shield, and gloves; doffing removes gloves first, followed by eye protection, gown, and mask/respirator last, followed by immediate hand hygiene.
- Used sharps must never be bent, broken, or recapped with two hands, and must go immediately into a puncture-resistant container that is replaced when two-thirds to three-quarters full.
- Sterile fields must be maintained at or above waist level, kept in continuous vision without reaching across, and protected against strike-through moisture; contaminated items or fields must be discarded and replaced.
- The practical nurse collects focused infection data, reports findings such as fever or purulent drainage to the RN, reinforces client education, and defers initial comprehensive assessment and care planning to the RN.
