When hands are visibly dirty, washing with soap and water is necessary because mechanical cleaning with soap lifts soil and microbes from the skin and running water flushes them away. Do this for at least 20 seconds, scrubbing all surfaces—palms, backs of hands, between fingers, under nails, and wrists—then rinse thoroughly. Dry with a clean disposable towel and use it to turn off the faucet to avoid recontamination. Alcohol-based sanitizers don’t remove visible dirt, so they aren’t appropriate here. Rinsing with cold water alone won’t remove the soil, and delaying washing or just reapplying lotion and washing later won’t adequately clean the hands before resident care.

Proper denture and mouth care means cleaning both the dentures and the oral tissues, and checking the fit after cleaning. Removing dentures allows thorough cleaning of the appliance to prevent plaque buildup and irritation. Cleaning dentures separately, then brushing the gums, tongue, and palate with a soft brush helps remove debris from the mucosa and keeps tissues healthy. Rinsing removes cleaner or loose particles. Reinserting dentures when appropriate and checking the fit ensures they sit comfortably and won’t cause ulcers or rubbing; report any poor fit. This approach reduces infection risk and supports comfort and function for eating and speaking.

Blood pressure has two numbers: systolic pressure (when the heart contracts) and diastolic pressure (when the heart rests). For adults, a typical normal range is about 100/60 to 140/80. This window covers readings that usually indicate good perfusion without excessive arterial resistance, while allowing for normal daily variation due to activity, posture, or individual differences. Readings below 100/60 can cause symptoms like dizziness from too little pressure, and readings above 140/80 are generally flagged for further evaluation for hypertension in basic nursing practice. The range used here balances recognizing normal variability with the need to identify potentially concerning readings. Other options either start too low or go beyond what’s commonly considered normal in this CNA context.

The purpose of a draw sheet is to aid turning and moving a resident in bed. Placed under the resident from shoulders to hips, it gives the caregiver a firm, graspable surface to lift, pivot, and slide the person. This makes repositioning safer and easier for both the resident and the caregiver by reducing friction and the risk of skin injury from dragging. Keeping the mattress dry is important, but the draw sheet’s role is specifically to help with turning and moving in bed and during transfers. It’s not used to stabilize the head position, to determine weight, or to secure the resident to the bed with straps.
