Final answer:
A disinfectant is a chemical that should never be added to the footbath with the client’s feet as it can cause skin irritations and burning sensations. So the correct answer is Option B.
Step-by-step explanation:
The chemical that should never be added to the footbath with the client’s feet is a disinfectant. Disinfectants are substances that are applied to non-living objects to destroy microorganisms, and they can be too harsh for human skin, especially on the sensitive skins at the feet. Using a disinfectant in a footbath can cause skin irritations, unpleasant burning sensations, and might damage the skin. Always ensure that only skin-friendly substances with non-harming chemicals are used in footbaths, such as salts or essential oils.
