Answer to Question 1
ANS: B
Candida albicans is the most common oral infection appearing in extremely debilitated patients. Medications that predispose a person to C. albicans infections are those that depress the immune system and those that cause xerostomia. C. albicans is a fungus and therefore is treated with antifungal agents such as nystatin (Mycostatin). Steroids, topical anesthetics, and topical anti-inflammatory agents are not used to treat C. albicans.
Answer to Question 2
ANS: A
Thrush is characterized by white, milk curd-appearing plaques that are attached to the oral mucosa. Canker sores can appear as ulcers 0.5 to 2 cm in diameter on surfaces that are not attached to bone, such as the tongue, gums, or inner lining of the cheeks and lips. Cold sores (fever blisters) are most commonly found at the junction of the mucous membrane and the skin of the lips or nostrils, although they can occur inside the mouth, especially affecting the gums and roof of the mouth. Mucositis is a general term used to describe a painful inflammation of the mucous membranes of the mouth.
