3.2 PPE & Isolation Precautions

Personal Protective Equipment (PPE)

Personal protective equipment (PPE) is the barrier clothing and gear a nursing assistant wears to block the transmission of microorganisms between residents, staff, and the environment. The four main items are the gown, mask (or N95 respirator), eye protection (goggles or face shield), and gloves. The exam expects you to know not only when to wear PPE, but the exact order in which to put it on and take it off, because contamination happens most often during removal.

PPE choice follows the task. Gloves are worn whenever contact with body fluids or non-intact skin is likely. A gown is added when clothing could be soiled or splashed. A mask and eye protection are added when splashing or spraying of fluids near the face is possible — for example during oral suctioning by a nurse or emptying a large drainage container. PPE is single-use: remove and discard it before leaving the resident's room, then perform hand hygiene.

Donning and Doffing Order

The sequence matters because it minimizes contamination of the CNA's skin and clothing. A memory aid: you put PPE on in the order you would get dressed (clothing first, gloves last), and you take it off worst-first (the dirtiest item, the gloves, comes off first). The CDC doffing order is conveniently alphabetical: Gloves, Goggles, Gown, Mask.

Key points the test asks about:

• Perform hand hygiene before donning and again immediately after doffing.
• When donning, gloves go on last and pull up over the cuffs of the gown so no skin is exposed at the wrist.
• When doffing, gloves come off first because they are the most contaminated. Remove the mask last because the front of the mask is contaminated — touch only the ties or ear loops, never the front.
• Remove gown and gloves inside the room and discard them there. For airborne precautions, the N95 respirator is removed just outside the door after the door is closed, so you are protected while still in the room.

Transmission-Based (Isolation) Precautions

When standard precautions are not enough, transmission-based precautions are added based on how the specific germ spreads. They never replace standard precautions — they layer on top. The exam commonly asks you to match a disease to its precaution and PPE.

A tip for remembering the airborne diseases: "My Chicken Has TB" — Measles, Chickenpox, and TB all require airborne precautions, an N95 respirator, and a negative-pressure airborne infection isolation room (AIIR). The CDC notes an AIIR provides 6–12 air exchanges per hour. A regular surgical mask is not adequate for airborne diseases.

Handling Contaminated Linens and Waste

Soiled linens, waste, and equipment are reservoirs for pathogens. Follow these rules on the exam and on the job:

• Always wear gloves when handling soiled linens or emptying containers of body fluid.
• Hold dirty linens away from your uniform and never let them touch the floor or your body — anything that touches the floor is considered contaminated.
• Roll soiled linens inward so the dirtiest surface is folded to the inside, and never shake them, because shaking aerosolizes microorganisms.
• Place soiled linens directly into the designated linen bag or hamper, not on furniture, an overbed table, or the floor.
• Dispose of contaminated waste in the proper biohazard (red) bag, and place sharps in a puncture-resistant sharps container — never recap a needle.
• Carry clean linens away from your uniform as well, and never return unused linen from a resident's room to the clean supply — once it enters the room it is considered contaminated.

For residents on transmission-based precautions, follow the facility's labeled bagging and double-bagging procedures so that contaminated items leave the room safely. Dedicated equipment — a blood-pressure cuff, thermometer, or stethoscope kept in the room — should stay with that resident and be disinfected before it leaves.

Psychosocial Care During Isolation

Isolation protects others, but it can leave a resident feeling lonely, anxious, depressed, or rejected — being placed "behind a door" with staff in gowns and masks is frightening, especially for residents with dementia. The CNA's responsibility is to meet infection-control rules and the resident's emotional needs.

• Explain, in simple terms, why the precautions are needed and that they are not a punishment.
• Greet the resident and make eye contact before putting the mask on when possible, so they can see your face.
• Spend unhurried time, answer the call light promptly, and provide diversion such as conversation, a clock, a calendar, a television, or visits.
• Make sure the resident still receives meals, activities, and personal care on schedule — isolation is never a reason to provide less care.

Observe and report any signs of withdrawal or worsening mood to the nurse. Treating an isolated resident with the same dignity and attention as any other resident upholds their rights and is frequently tested on the exam.
