A nurse is reinforcing teaching with a client about how to perform a breast self exam (BSE). The nurse should identify which of the following findings as an indication of breast cancer?

Choice A reason: This is a correct statement, because using a soft toothbrush or foam swab for oral care can help prevent trauma and irritation to the mucous membranes of the mouth, which are inflamed and ulcerated due to stomatitis. The client should brush the teeth gently and avoid using dental floss.

Choice B reason: This is an incorrect statement, because using an alcohol-based mouthwash can cause burning, drying, and further damage to the mucous membranes of the mouth, which are already compromised by stomatitis. The client should avoid using any mouthwash that contains alcohol, menthol, or other harsh ingredients.

Choice C reason: This is a correct statement, because using a straw when drinking liquids can help reduce the contact and friction of the fluids with the mouth sores, which can cause pain and discomfort. The client should drink plenty of fluids to prevent dehydration and maintain hydration.

Choice D reason: This is a correct statement, because rinsing the mouth frequently with a hydrogen peroxide solution can help cleanse and disinfect the mouth, and promote healing of the mouth sores. The client should dilute the hydrogen peroxide with water and rinse the mouth at least four times a day, or as prescribed by the provider.

Choice A reason: This is a normal finding, not an indication of breast cancer. Lumps that are mobile and tender upon palpation prior to a menstrual period are usually benign and related to hormonal changes.

Choice B reason: This is a normal finding, not an indication of breast cancer. Multiple round masses that are tender and found in both breasts are usually benign and related to fibrocystic breast changes.

Choice C reason: This is a normal finding, not an indication of breast cancer. Bilaterally darkened areolas are usually benign and related to genetic factors, pregnancy, or aging.

Choice D reason: This is an abnormal finding, and an indication of breast cancer. A nontender hard lump that is palpated in one breast is usually malignant and related to abnormal cell growth.
