Foot Care for CNAs: Step-by-Step Guide and Exam Tips

Foot care means washing, drying, inspecting, and moisturizing a resident's feet. It sounds straightforward, but this skill has several rules that exist for specific medical reasons, and getting those rules wrong can cause real harm. In a care facility, residents often cannot bend down to clean and inspect their own feet. Many have conditions like diabetes, poor circulation, or nerve damage that make foot problems especially dangerous.

For residents with diabetes, a small cut or sore on the foot that a healthy person would barely notice can become a serious wound that takes months to heal and, in severe cases, can lead to infection and amputation. That is not meant to frighten you but to explain why foot care in a nursing facility is treated as a clinical responsibility with specific protocols, not just a hygiene task. As a CNA, your role is to clean carefully, inspect thoroughly, and report any changes you find. You do not diagnose or treat. You observe and communicate.

Why This Skill Matters on the CNA Exam

Foot care is an official NNAAP skill and may appear on your certification exam. The evaluator watches for the safety behaviors that protect residents with high-risk conditions. The most closely watched steps are testing the water temperature before placing feet in the basin, drying thoroughly between the toes, and applying lotion only to the tops and soles of the feet and not between the toes. Each of these rules has a clear reason behind it, and knowing the reason will help you remember the rule.

The evaluator also watches for skin inspection at the end of the procedure. This is not just about observing, you are expected to verbally state that you would report your findings to the nurse. In a real care setting, this reporting step can lead to early treatment that prevents a minor issue from becoming a serious wound.

What You Need

• Wash basin
• Warm water (test temperature before use)
• Soap or bath wash
• Washcloth
• Two towels (one for the floor under the basin, one for drying)
• Lotion, if ordered by the nurse or care plan
• Clean socks
• Disposable gloves
• Nail care supplies, if ordered (but note the scope restriction below)

Step-by-Step: Foot Care

1. Wash your hands. Perform hand hygiene before touching any supplies or the resident. This is the first step of every clinical skill.
2. Gather your supplies. Collect everything you need before entering the room so you do not have to leave the resident mid-procedure. A forgotten item means leaving a resident alone who may be in an awkward or unsafe position.
3. Identify the resident. Check the name band and greet the resident by name to confirm you are with the correct person.
4. Explain the procedure. Tell the resident that you are going to perform foot care. Give them a moment to respond or ask questions.
5. Fill the basin with warm water. Fill it about half full. Before you ever place it near the resident, test the temperature on the inside of your wrist. The inside of the wrist is more sensitive than the palm and gives a more accurate read on temperature. Water that is comfortable on your wrist is appropriate for most residents. For residents with diabetes or reduced sensation, err on the cooler side. Water that feels warm to you can feel extremely hot to a resident who cannot accurately sense temperature.
6. Position the resident comfortably. Help the resident sit in a chair or at the edge of the bed with their feet in a comfortable position you can easily reach. Place a towel on the floor under the basin to protect the floor and to catch drips.
7. Place feet in the basin. Lower one or both feet into the water. If the care plan indicates a soak, allow the feet to soak for 5 to 10 minutes to soften the skin. Do not soak feet without a specific order, particularly for residents with diabetes or circulation problems. Soaking for too long can actually soften skin to the point where it breaks down more easily.
8. Apply gloves. Put on disposable gloves before washing. You will come into contact with skin, nails, and potentially broken skin during this procedure.
9. Wash both feet. Using a soapy washcloth, wash the entire surface of each foot: the top, the sole, the heel, and each toe individually. Wash between each toe with particular care. The spaces between toes are warm and moist, which makes them a common site for fungal infections. Cleaning between the toes removes the debris and bacteria that contribute to those infections.
10. Rinse thoroughly. Rinse all soap off each foot and between every toe. Soap residue left on the skin can cause irritation, especially for residents with sensitive skin.
11. Dry each foot completely. Lift one foot out of the water and pat it dry with the towel. Start with the top of the foot and work toward the sole. Then carefully dry between every toe by patting the spaces gently. This step is critical. Moisture left between the toes creates the exact conditions that fungi thrive in. Athlete's foot and similar infections begin with consistently damp interdigital spaces (the spaces between the toes). Dry each space individually and thoroughly.
12. Apply lotion, if ordered. If the care plan includes lotion for foot care, apply a small amount to the palm of your gloved hand and rub it onto the top and sole of the foot. Do not apply lotion between the toes. Lotion between the toes traps moisture and promotes the same fungal growth that you are trying to prevent by drying thoroughly. This rule is commonly tested on the NNAAP exam.
13. Inspect the skin of both feet. Before putting on socks, look carefully at the skin of each foot. You are looking for redness, which can indicate early pressure injury or inflammation; cracks, especially around the heels; blisters or open areas; swelling; discoloration; or anything that looks abnormal compared to your baseline understanding of this resident. Note your findings mentally or in writing so you can report them accurately.
14. Apply clean socks. Put clean socks on the resident's feet. Socks protect the skin, keep the feet warm (which is a comfort issue for most elderly residents), and cover any areas you observed that need monitoring.
15. Clean up. Empty the basin in the sink or bathroom. Rinse it out, dry it, and return it to its storage location. Dispose of used washcloths and towels in the appropriate laundry receptacle. Remove your gloves by rolling them inside out and dispose of them.
16. Wash your hands. Perform hand hygiene after removing your gloves. Gloves are not a substitute for hand washing.
17. Ensure resident comfort. Help the resident into a comfortable position. Lower the bed to a safe height and place the call light within reach.
18. Record and report. Document that foot care was provided. Report any skin findings to the nurse immediately, particularly redness, open areas, blisters, swelling, or changes from a previous observation. Early reporting can prevent a small problem from becoming a large one.

A note on nail care: In most states, CNAs are not permitted to trim or cut residents' nails without specific training and an explicit order from a nurse or physician. If you notice that a resident's nails need trimming, report this to the nurse rather than attempting to trim them yourself. Check your state's rules and your facility's policy to know the scope of nail care for CNAs in your area.

What the Examiner Looks For

• Water temperature is tested on the inside of the wrist before the resident's feet are placed in the basin
• Gloves are worn throughout the washing and drying steps
• Both feet are washed thoroughly, including between every toe
• Feet are dried completely, with special attention to the spaces between the toes
• Lotion is applied to the tops and soles of the feet only, not between the toes
• Skin is inspected on both feet and findings are reported (or the student states they would report to the nurse)
• Clean socks are applied after care is complete
• Supplies are cleaned and stored properly
• Hand hygiene is performed before and after the skill

Common Mistakes to Avoid

• Not testing water temperature. Filling the basin and immediately putting the resident's feet in without testing first is a common and potentially harmful mistake. For diabetic residents especially, water that feels comfortable to you can cause burns because they have reduced sensation in their feet.
• Leaving moisture between the toes. Students often pat the tops and soles dry and then move on. Go back and dry each interdigital space individually. It takes 10 extra seconds and prevents fungal infections.
• Applying lotion between the toes. This is the most commonly tested rule in foot care, and it is frequently missed. Lotion between the toes locks in moisture and creates conditions for fungal growth. Apply lotion only to the top and sole of each foot.
• Skipping the skin inspection. The inspection step is on the checklist. Finishing the care, putting on socks, and leaving without looking at the skin means missing the most clinically important part of the skill from a resident safety standpoint.
• Attempting to trim nails. This is outside the CNA's scope in most states without a specific order and training. If nails need trimming, report it. Never trim without confirming your facility's policy and having an order.
• Not reporting findings. On the exam, you are expected to verbalize that you would report observations to the nurse. Completing the physical steps without mentioning documentation and reporting is an incomplete performance of the skill.
