A nurse is caring for a child who has pertussis. The child's parent asks the nurse what the common name for this disease is. The nurse should respond with which of the following common names?

Choice A reason: This choice is incorrect because 1 cup of cooked rice provides more than 1 oz of grains. According to the U.S. Department of Agriculture (USDA), one-ounce equivalent of grains equals one slice of bread, one cup of ready-to-eat cereal, or half a cup of cooked rice, pasta, or cereal. Therefore, 1 cup of cooked rice provides about 2 oz of grains.

Choice B reason: This choice is incorrect because 1/2 slice of white bread provides less than 1 oz of grains. As explained above, one-ounce equivalent of grains equals one slice of bread, so 1/2 slice of white bread provides only 0.5 oz of grains.

Choice C reason: This choice is correct because 1 cup of ready-to-eat cereal flakes provides exactly 1 oz of grains. As explained above, the one-ounce equivalent of grains equals one cup of ready-to-eat cereal, so 1 cup of ready-to-eat cereal flakes provides 1 oz of grains.

Choice D reason: This choice is incorrect because 1/2 white flour tortilla provides less than 1 oz of grains. According to the USDA, one-ounce equivalent of grains equals one small tortilla (6 inches in diameter), so 1/2 white flour tortilla provides only about 0.4 oz of grains.

Choice A: Skin cancer is a malignant growth of the skin cells, which can be caused by exposure to ultraviolet radiation, genetic mutations, or immunosuppression. Skin cancer does not affect the mouth and does not cause a white, milky plaque. Skin cancer may cause changes in the color, shape, size, or texture of a mole or a skin lesion.

Choice B: Candidiasis or thrush is a fungal infection of the mouth, which can be caused by overgrowth of Candida albicans, a type of yeast that normally lives in the body. Candidiasis or thrush can occur in people who have a weakened immune system, such as those who have a systemic disorder, take antibiotics, immunosuppressants, or corticosteroids, or have a smoking history. Candidiasis or thrush can cause soreness in the mouth and difficulty eating. Candidiasis or thrush can also cause a white, milky plaque that does not come off with rubbing.

Choice C: Squamous cell carcinoma is a type of skin cancer that affects the squamous cells, which are flat cells that form the outer layer of the skin. Squamous cell carcinoma can occur in areas that are exposed to sun damage, such as the face, ears, lips, or neck. Squamous cell carcinoma does not affect the mouth and does not cause a white, milky plaque. Squamous cell carcinoma may cause a red, scaly, crusty, or bleeding bump or patch on the skin.

Choice D: Herpes simplex is a viral infection that affects the skin and mucous membranes, such as the mouth, lips, genitals, or eyes. Herpes simplex is transmitted by direct contact with an infected person or object. Herpes simplex does not cause a white, milky plaque. Herpes simplex may cause painful blisters or ulcers that burst and form scabs.
