Any care task involving contact with blood, body fluids, mucous membranes, or non-intact skin always requires gloves. That’s the universal rule across every healthcare and caregiving setting. But several specific tasks fall under this umbrella, and if you’re studying for a CNA exam, nursing program, or simply providing care at home, knowing exactly which ones matter.
The Universal Rule Behind Glove Use
The CDC’s standard precautions state that gloves are required during any procedure or patient-care activity where contact with blood, body fluids, secretions, or excretions is anticipated. OSHA’s bloodborne pathogens standard makes this a legal requirement for workers: gloves must be worn when hand contact with blood or other potentially infectious materials can be reasonably anticipated.
“Other potentially infectious materials” covers a long list: semen, vaginal secretions, cerebrospinal fluid, amniotic fluid, saliva during dental procedures, any body fluid visibly contaminated with blood, and any situation where you can’t tell which body fluid you’re dealing with. If there’s any doubt, gloves go on.
Perineal Care and Incontinence Tasks
Perineal care is the task most commonly highlighted in nursing assistant training as one that always requires gloves. This includes cleaning the genital and rectal area during bathing, after toileting, and when changing incontinence briefs. The protocols are detailed and strict: you put on gloves before beginning, remove them and wash your hands after cleaning the front, then put on a fresh pair before cleaning the buttocks and rectal area. This glove-change-in-the-middle step catches many students off guard, but it prevents spreading bacteria from one area to another.
The same applies to emptying bedpans, urinals, or any container holding body waste. After emptying, you remove your soiled gloves, wash your hands, and put on a new pair before assisting with any further cleaning. Every contact with urine, stool, or the skin surrounding those areas demands a fresh set of gloves.
Contact With Blood or Open Wounds
Any task where blood is present or likely requires gloves, no exceptions. This includes wound care, dressing changes, cleaning cuts or abrasions, and handling bandages soiled with blood or drainage. If a resident or patient has non-intact skin (a rash, surgical incision, pressure sore, or skin tear), gloves are mandatory before you touch the area.
Blood draws and other vascular access procedures also require gloves. OSHA is so firm on this that even in volunteer blood donation centers, where a narrow exception exists, gloves are still required whenever the worker has any break in their own skin, when blood contamination of the hands is possible, or when the worker is still in training.
Handling Soiled Linens and Medical Waste
Soiled bed sheets, towels, gowns, and curtains carry the same risks as direct body fluid contact. CDC guidelines call for reusable, tear-resistant rubber gloves before handling or laundering contaminated linens. This applies whether you’re stripping a bed after an incontinence episode, bundling up blood-stained sheets, or transporting laundry bags to a washing area. The gloves used for this task should be sturdier than standard exam gloves because fabric can hide sharps like forgotten needles.
Applying or Removing Transdermal Medications
This one surprises many new caregivers. When you apply or remove a medication patch, you should always wear gloves. Transdermal patches are designed to deliver drugs through the skin, and that includes your skin if you touch the medicated surface. Common transdermal medications include fentanyl (a powerful pain reliever), nitroglycerin (a heart medication), estrogen, and nicotine patches. Bare-handed contact can cause the drug to absorb into your body, potentially causing dizziness, drops in blood pressure, or other unwanted effects. Gloves go on before the old patch comes off and stay on until the new one is in place.
Handling Hazardous Drugs
Chemotherapy drugs and other hazardous medications require not just gloves but double gloving. NIOSH guidelines call for two pairs of gloves when compounding, administering, or disposing of these drugs. The inner glove goes under the gown cuff, and the outer glove goes over it. This creates a sealed barrier because hazardous drugs can cause tissue damage, reproductive harm, or cancer risk even from small skin exposures. If you work in oncology or handle any medication labeled as hazardous, this double-glove protocol applies every single time.
Oral Care and Mucous Membrane Contact
Mucous membranes line the mouth, nose, eyes, and genital areas. Any care task that involves touching these surfaces requires gloves. Oral care (brushing teeth, swabbing the mouth, applying oral moisturizer) is a routine task that always calls for gloves because saliva is considered potentially infectious, and the mouth contains mucous membranes. The same goes for suctioning, nasal care, or inserting a catheter.
When to Change Gloves Mid-Task
Putting gloves on at the start isn’t enough. The World Health Organization’s hand hygiene guidelines make clear that gloves must be removed and hands washed immediately after any exposure to body fluids. In practice, this means you change gloves between dirty and clean steps on the same person. Moving from perineal care to repositioning a patient, for example, requires a glove change. Moving from one patient to another always requires a glove change. Wearing the same pair of gloves across multiple tasks or multiple patients is a serious infection control violation, even if the gloves look clean.
A good rule of thumb: if you’ve touched something contaminated, the gloves come off, your hands get washed, and fresh gloves go on before you touch anything else. Gloves protect you from the patient’s body fluids and protect the patient from cross-contamination. They only work when you change them at the right moments.
