During an oral assessment, the nurse observes white patches on the client's tongue and buccal mucosa that can be easily wiped away. What should the nurse suspect?

Rationale: A. Oral candidiasis, commonly known as thrush, is caused by an overgrowth of the fungus Candida albicans. It presents as white, creamy patches on the tongue, inner cheeks, or buccal mucosa that can be wiped away, often revealing red, inflamed tissue underneath. This is the classic presentation and matches the nurse’s observation. B. Aphthous ulcers, or canker sores, are small, round, painful ulcers with a white or yellow center and a red halo. Unlike thrush, they are discrete lesions that cannot be wiped away and are usually limited to the mucosa rather than forming widespread patches. C. Leukoplakia presents as white or gray patches on the tongue or oral mucosa that cannot be wiped away. It is often associated with chronic irritation, smoking, or alcohol use, and may be precancerous. The key difference from thrush is that leukoplakia is adherent and persistent. D. Streptococcus infections of the throat (strep throat) usually present with redness, swelling, exudate on the tonsils, and sore throat. They do not produce white patches that can be wiped off from the tongue or buccal mucosa.
