5.2 Infection Control, Hand Hygiene, and Standard Precautions
Key Takeaways
- Hand hygiene is required before and after resident contact, after glove removal, after contact with body fluids, and whenever hands are visibly soiled.
- Standard precautions treat blood, body fluids, non-intact skin, and mucous membranes as potentially infectious for every resident.
- Personal protective equipment must be selected for the expected exposure and removed without contaminating clean skin or clothing.
- A nurse aide follows isolation instructions, cleans shared equipment, and reports infection signs such as fever, drainage, cough, diarrhea, or new confusion.
Breaking the Chain of Infection
Infection control is a core part of Basic Nursing Skills because nurse aides move between residents, rooms, linens, equipment, meals, toileting, and personal care. Microorganisms can spread through direct contact, droplets, contaminated hands, soiled equipment, respiratory secretions, blood, stool, urine, wound drainage, or shared surfaces. The aide cannot see most germs, so safe habits must happen every time, not only when a resident looks ill.
Hand hygiene is the most repeated infection control action. Use facility-approved alcohol-based hand rub when hands are not visibly soiled and policy allows it. Use soap and water when hands are visibly dirty, after known or suspected contact with certain organisms as directed by policy, after toileting tasks, and whenever alcohol rub is not appropriate. Hand hygiene is needed before resident contact, before clean tasks, after body fluid exposure risk, after touching the resident, after touching the resident's surroundings, and after removing gloves.
Gloves do not replace hand hygiene. Gloves protect only when used for the right task and changed at the right time. Wear gloves when contact with blood, body fluids, mucous membranes, non-intact skin, contaminated items, or soiled linens is likely. Remove gloves before touching clean surfaces such as a doorknob, keyboard, charting station, clean supply cart, or another resident. Wash or sanitize hands after removing gloves because removal can contaminate the hands.
Standard precautions apply to every resident. The nurse aide does not need to know a diagnosis before protecting against blood and body fluids. Transmission-based precautions add instructions for certain infections and may include gown, mask, eye protection, respirator, dedicated equipment, room placement, or special cleaning. The aide follows posted and care-plan instructions exactly and asks the nurse if the sign or supplies are unclear.
Infection Control Actions
| Situation | Safe aide action | Why it matters |
|---|---|---|
| Before feeding a resident | Perform hand hygiene and help the resident clean hands | Prevents organisms from entering the mouth |
| Emptying a drainage bag | Wear gloves, avoid touching the spout to the container, clean as directed | Prevents contamination and urinary infection risk |
| Handling soiled linen | Hold away from uniform, avoid shaking, place in proper bag | Prevents spreading organisms into the air or onto clothing |
| Shared equipment | Clean or disinfect between residents according to policy | Prevents resident-to-resident spread |
| Coughing resident | Follow respiratory hygiene and report fever, distress, or new symptoms | Supports early assessment and isolation decisions |
Personal protective equipment, or PPE, must match the task. Gloves may be enough for helping with toileting when splashing is not expected. A gown protects clothing when soiling is likely. A mask and eye protection may be needed when splashes or sprays could reach the face. Put PPE on before exposure and remove it in a way that keeps contaminated surfaces away from clean skin and clothing. Dispose of it in the proper container, then perform hand hygiene.
Clean and dirty must be kept separate. Do not place clean supplies on a dirty overbed table. Do not carry clean linens against a soiled uniform. Do not return unused supplies from an isolation room to the clean supply area unless policy specifically allows a safe process. Do not put a used thermometer, blood pressure cuff, gait belt, basin, or lift sling back into circulation without cleaning as required.
Resident dignity still matters. Isolation does not mean ignoring the resident or making them feel blamed. Explain care in simple language, keep call light and personal items within reach, and support social contact in approved ways. If a resident does not understand why they need a mask, hand hygiene, or room restriction, report the concern and follow the nurse's direction.
Report signs that may suggest infection or worsening illness: fever, chills, new cough, shortness of breath, sore throat, burning with urination, cloudy or foul-smelling urine, diarrhea, vomiting, drainage, redness around a wound, sudden weakness, new confusion, poor intake, or unusual fatigue. The nurse aide does not diagnose infection. The aide notices, protects others from exposure, and reports facts promptly.
