Infection Control and PPE

Infection Control Is Built Into Every Task

The Prometric Idaho outline lists infection prevention and control within Promotion of Safety. That placement matters: infection control is not a separate skill used only in isolation rooms. It is part of bathing, feeding, toileting, transfers, linen changes, vital signs, and equipment cleaning. The chain of infection has six links: infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host. The CNA's strongest tool, hand hygiene, breaks the mode-of-transmission link, which is why it appears on nearly every Prometric skill.

Standard Precautions apply to every resident, every time, regardless of known diagnosis. Treat blood, body fluids, secretions, excretions except sweat, non-intact skin, and mucous membranes as potentially infectious. Use gloves when contact with those materials is possible, but remember the glove rule: gloves protect only when used for the right task and changed at the right time. Long fingernails, artificial nails, and rings under gloves harbor organisms and are restricted in most Idaho facilities.

Hand Hygiene Decisions and the Skills-Test Critical Steps

Use hand hygiene before touching a resident, before clean care, after touching a resident, after touching contaminated surfaces, after contact with body fluids, after removing gloves, before eating, and after using the restroom. Alcohol-based hand rub is acceptable when hands are not visibly soiled. Soap and water is required when hands are visibly dirty, after restroom use, before eating, and for spore-forming organisms such as Clostridioides difficile (C. diff), where alcohol does not kill spores.

On the Prometric hand-washing skill, evaluators score these critical steps:

• Turn on water and wet hands with fingertips pointed down, keeping hands lower than the elbows
• Apply soap and lather, rubbing all surfaces for at least 20 seconds (about two rounds of "Happy Birthday")
• Clean under and around the nails and between fingers using friction
• Rinse from clean (wrists) to dirty (fingertips) with fingers pointing down
• Dry with a clean paper towel, then use a fresh, dry paper towel to turn off the faucet so you do not recontaminate clean hands
• Dispose of towels in the proper container without touching the can

Think in moments, not schedules: clean your hands when the task changes from dirty to clean, from one resident to another, or from contaminated equipment back to the resident.

PPE, Transmission-Based Precautions, and Disposal

Personal protective equipment (PPE) and Transmission-Based Precautions add barriers when the resident's condition calls for them. Follow the sign on the room, the care plan, and the nurse.

Donning order (putting on): gown, mask or respirator, goggles or face shield, then gloves. Doffing order (taking off): gloves first, then goggles or face shield, then gown, then mask or respirator last, with hand hygiene immediately after, and again at the end. Remove PPE without touching contaminated fronts. If your hands become contaminated mid-removal, clean them before continuing.

Clean equipment before it moves to another resident, and keep clean supplies away from soiled surfaces. Roll soiled linen inward, hold it away from your uniform, and place it directly in the hamper; never shake linens, which aerosolizes organisms. Sharps go directly into an approved sharps container, never recapped, bent, or hand-carried. Report fever, new cough, drainage, diarrhea, rash, worsening wounds, redness around a device, cloudy urine, sudden confusion, and your own illness, since Idaho skilled-nursing rules require staff to report illness to protect residents.

Glove Technique, Isolation Rooms, and Common Traps

Gloves are the most-used PPE and the most-misused. Apply gloves only after hand hygiene, and over the cuffs of a gown when gowned. Change gloves and perform hand hygiene between tasks on the same resident when moving from a dirty area to a clean one, for example after perineal care before adjusting the oxygen cannula. Remove gloves by the glove-to-glove, skin-to-skin method: grasp the outside of one cuff and peel it off inside-out, ball it in the gloved hand, then slide a bare finger inside the second cuff and peel it off over the first, discarding both without touching the contaminated outsides.

For an isolation room, gather everything you need before entering so you do not have to leave mid-task. Items that cannot be disinfected stay in the room (dedicated equipment), and a designated person or pass-through is used to bring in supplies. Double-bag only when the outside of the first bag is contaminated or wet. When leaving, doff PPE inside the doorway, perform hand hygiene, then exit.

High-yield infection-control traps the Idaho written test likes to probe:

The CNA's infection-control job is simple but strict: clean hands at the right moments, correct barriers, clean equipment, safe disposal, and fast reporting.
