🧼 Lesson Discussion: Infection Prevention and Control (IPAC)
1️⃣ Five Moments of Hand Hygiene (WHO Guidelines)
Hand hygiene is the single most effective way to prevent the spread of infection. Perform hand hygiene:
Before touching a patient
Before clean/aseptic procedures
After body fluid exposure/risk
After touching a patient
After touching patient surroundings
2️⃣ Proper Handwashing (40–60 seconds)
Use when hands are visibly soiled or after contact with potentially infectious material.
Steps (about 40–60 seconds):
Wet hands with water
Apply enough soap to cover all hand surfaces
Rub palm to palm
Right palm over left dorsum and vice versa
Palm to palm with fingers interlaced
Backs of fingers to opposing palms with fingers interlocked
Rotational rubbing of left thumb clasped in right palm and vice versa
Rotational rubbing of clasped fingers in palm
Rinse hands thoroughly
Dry with a single-use towel
Use towel to turn off tap
3️⃣ Proper Hand Rubbing with Alcohol-Based Rub (20–40 seconds)
Use when hands are not visibly dirty
Apply a palmful of product
Follow the same rubbing steps as above, skipping water/soap
Continue until hands are dry — do not wipe off
4️⃣ Transmission-Based Precautions
Used in addition to Standard Precautions when specific infections are suspected/confirmed.
🫁 Airborne Precautions
Acronym: My Chicken Hez TB
Measles
Chickenpox (Varicella)
Herpes zoster (disseminated)
Tuberculosis
Measures:
N95 respirator
Negative pressure room
Limit patient movement
💧 Droplet Precautions
Acronym: SPIDERMAN
Sepsis
Pertussis
Influenza
Diphtheria (pharyngeal)
Epiglottitis
Rubella
Mumps / Meningitis (Neisseria)
Adenovirus
Measures:
Surgical mask within 1–2 meters
Eye protection if risk of splash
Limit patient transport
🖐️ Contact Precautions
Acronym: MRS WEE
Multidrug-resistant organisms (MRSA, VRE)
Respiratory infections (RSV, parainfluenza)
Skin infections (scabies, impetigo)
Wound infections
Enteric infections (C. difficile)
Eye infections (conjunctivitis)
Measures:
Gloves and gown on entry
Dedicated equipment
Enhanced cleaning
5️⃣ Standard Precautions — Applied to all patients
Hand hygiene before/after every patient contact
Use of PPE (gloves, masks, eye protection) as needed
Respiratory hygiene/cough etiquette
Safe injection practices
Proper handling of linens and waste
Environmental cleaning
6️⃣ Chain of Infection
To prevent infection, break the chain at any point:
Infectious Agent — Bacteria, viruses, fungi
Reservoir — Where the agent lives (people, equipment, water)
Portal of Exit — How it leaves (cough, blood, wounds)
Mode of Transmission — Contact, droplet, airborne
Portal of Entry — Mouth, nose, mucous membranes, broken skin
Susceptible Host — Person with low immunity
7️⃣ Role of the CNA in IPAC
Perform proper hand hygiene and use PPE appropriately
Follow isolation precautions correctly
Clean and disinfect patient equipment
Report any signs of infection to the nurse (e.g., redness, swelling, drainage)
Educate patients/families on hygiene practices
8️⃣ Vital Signs to Monitor if Infection is Suspected
Temperature (fever may indicate infection)
Pulse (tachycardia may be present)
Respiration rate (may increase with fever or respiratory infection)
Blood pressure (may drop in severe sepsis)
Oxygen saturation (especially in respiratory infections)
Pain score (localized or generalized discomfort)
