Infection Control & Standard Precautions
Key Takeaways
- Standard Precautions treat all blood, body fluids, secretions, excretions (except sweat), non-intact skin, and mucous membranes as potentially infectious—hand hygiene is the single most effective measure.
- Transmission-based precautions add Contact, Droplet, and Airborne isolation beyond Standard Precautions when specific pathogens require them.
- Proper handwashing uses running water, soap, friction for at least 20 seconds, rinsing, and drying; alcohol-based hand rub is acceptable when hands are not visibly soiled.
- PPE donning order is gown first, then mask, goggles/face shield, gloves; doffing removes gloves first, then eye protection, gown, and mask—wash hands after removal.
- On the NY Prometric skills test, hand hygiene is evaluated throughout every skill; missing handwashing at required moments fails the skill.
Quick Answer: Use Standard Precautions for all residents; add Contact/Droplet/Airborne precautions per transmission type. Hand hygiene before and after every resident contact is non-negotiable on the NY five-skill exam.
Why Infection Control Dominates the NY Exam
Basic Nursing Skills is 35% of the written blueprint, and infection control threads through every clinical skill. Prometric evaluates hand hygiene throughout all five assigned skills—not as a standalone optional step. A missed handwash at a critical moment fails the entire skill.
NY nursing homes are surveyed by NYSDOH on infection prevention. CNAs are the front line for breaking the chain of infection in shared dining rooms, therapy gyms, and multi-bed units.
Chain of Infection
| Link | CNA Role |
|---|---|
| Infectious agent | Recognize signs of infection; report |
| Reservoir | Clean equipment; proper linen handling |
| Portal of exit | Use tissues, dressings, PPE |
| Mode of transmission | Hand hygiene, isolation, cough etiquette |
| Portal of entry | Avoid touching mucous membranes bare-handed |
| Susceptible host | Protect immunocompromised residents |
Breaking any link prevents spread. Hand hygiene breaks the mode of transmission link most often.
Standard Precautions
Apply to every resident, every time:
| Body Substance | Precaution |
|---|---|
| Blood | Gloves; face protection if splash risk |
| All body fluids | Gloves |
| Non-intact skin | Gloves |
| Mucous membranes | Gloves |
Sweat is excluded from Standard Precautions body-fluid list—a common exam trap.
Hand Hygiene Technique
Soap and water (20+ seconds friction):
- Wet hands with running water
- Apply soap; rub palms, backs, fingers, nails
- Rinse thoroughly
- Dry with clean towel; use towel to turn off faucet
Alcohol-based rub: apply to dry hands; rub until dry—use when hands not visibly soiled.
| When to Wash | Examples |
|---|---|
| Before | Resident contact, clean procedures, eating area |
| After | Body fluid contact, gloves removal, soiled linen |
| Between | Different body sites on same resident |
Transmission-Based Precautions
| Type | Examples | Key PPE |
|---|---|---|
| Contact | MRSA, C. diff, scabies | Gown + gloves; dedicated equipment |
| Droplet | Influenza, pertussis | Surgical mask within 3–6 feet |
| Airborne | TB, measles, varicella | N95 respirator + negative-pressure room |
C. difficile: soap-and-water handwashing preferred over alcohol rub because spores resist alcohol.
NY Nursing Home Application
Isolation signage on resident doors tells you which precautions to add. Never remove signs or share equipment between isolation rooms without cleaning per policy. Report torn gloves or PPE shortages before providing care that requires protection.
PPE Donning and Doffing
Don (put on): gown → mask → goggles/face shield → gloves
Doff (remove): gloves → goggles → gown → mask → hand hygiene
Doffing order prevents contaminating clean areas. Exam questions love reversed sequences.
Cleaning and Linen
- Place soiled linen in leak-proof bag at point of use—do not shake
- Hold linen away from uniform
- Clean dirtiest to cleanest surfaces; top to bottom
- Disinfect per facility policy after blood/body fluid spills
Waste Disposal
Soiled dressings and contaminated supplies go in red biohazard bags per facility color coding. Needles and sharps never go in regular trash—use puncture-resistant sharps containers only.
Bloodborne Pathogens
Treat all sharps and blood as infectious (HIV, HBV, HCV). Never recap needles; dispose in puncture-resistant container. Report needlestick immediately per facility exposure protocol.
Post-Exposure Steps
- Wash exposure site with soap and water (eyes: flush with water)
- Report to supervisor immediately
- Complete incident report
- Follow occupational health bloodwork protocol
Worked Scenario
Stem: "You finish perineal care on a Contact Precautions resident. What is the correct sequence?"
Remove gloves → perform hand hygiene → don new gown and gloves before touching the environment or next task. Skipping hand hygiene between glove changes is a skills-test critical failure.
NY Skills Exam Connection
Indirect-care steps on every NNAAP skill include hand hygiene at entry, before/after glove use, and before leaving. Practice until automatic so you preserve the 30-minute budget for skill performance.
Cough Etiquette and Respiratory Hygiene
Cover coughs with tissue or elbow; dispose of tissues; perform hand hygiene. Residents with respiratory symptoms may need droplet precautions—report new cough or fever before continuing group activities.
Common Exam Traps
- Alcohol rub after C. diff contact (wrong—use soap and water)
- Shaking soiled linen (spreads pathogens)
- Removing gown before gloves (contaminates hands)
- Skipping hand hygiene because gloves were worn
- Reusing gloves between residents without hand hygiene between
NYSDOH Infection Control Survey Focus
Infection control citations are among the most common NY nursing home survey findings. CNAs directly affect hand hygiene compliance rates observed by surveyors.
Multi-Drug Resistant Organisms (MDRO)
| Organism | Precaution |
|---|---|
| MRSA | Contact |
| VRE | Contact |
| C. diff | Contact + soap and water handwashing |
| CRE | Contact; report immediately |
Dedicated equipment stays in isolation room when possible. Clean shared equipment between residents.
Influenza and Respiratory Season
During flu season, NY facilities may restrict visitors and enforce droplet precautions for symptomatic residents. CNAs wear masks per policy; report own fever or cough before working—do not bring infection to vulnerable residents.
Food Service Infection Control
Wash hands before dining room setup and feeding assistance. Residents with contagious GI illness may eat in room on contact precautions—follow tray delivery protocol.
Personal Protective Equipment Stock
Report low PPE supply before starting care that requires gloves or gowns. Do not reuse disposable gloves between residents. Gown front is contaminated after contact precautions care.
Environmental Cleaning Responsibilities
CNAs may clean resident-specific items (overbed table, call light) with approved disinfectant. Blood spills require trained response—report and contain per exposure control plan.
