21. Deep fungal infections include all except a. histoplasmosis. b. coccidioidomycosis. c. blastomycosis. d. actinomycosis. ANSWER: D Actinomycosis is not a deep fungal infection. It is caused by a filamentous bacterium. Histoplasmosis is a deep fungal infection widespread in the Midwestern United States. Coccidioidomycosis is a deep fungal infection more prevalent in the Western United States. Blastomycosis is a deep fungal infection most common in the Ohio–Mississippi River basin area. REFF: Deep Fungal Infections, page 124 6 22. The initial infection and signs and symptoms of deep fungal infections, including histoplasmosis, coccidioidomycosis, and blastomycosis, are related to diseases in which location? a. Lung b. Kidney c. Lymph nodes d. Nasal cavity ANSWER: A Deep fungal infections are most commonly primary infections of the lung. The kidney is not the primary site for deep fungal infection. The lymph nodes are not the primary site for deep fungal infection. The nasal cavity may be a primary site for a rare fungal infection called mucormycosis. REFF: Deep Fungal Infections, page 124 6 23. Another name for verruca vulgaris is a. condyloma acuminatum. b. the common wart. c. Heck disease. d. focal epithelial hyperplasia. ANSWER: B Another name for verruca vulgaris is the common wart. Condyloma acuminatum is a benign papillary lesion sexually tr Answermitted and caused by a human papillomavirus (HPV), which is different from the papillomavirus that causes verruca vulgaris. Heck disease is caused by an HPV that is different from the types of HPV that cause verruca vulgaris and condyloma acuminatum. The disease presents with manifold mucosal nodules and resolves spontaneously. Focal epithelial hyperplasia is another name for Heck disease. REFF: Verruca Vulgaris, page 125 6 24. The image shows an oral condyloma acuminatum presenting in a child. The presence of condyloma acuminatum in a child suggests a. hypersensitivity. b. genetic predisposition. c. sexual abuse. d. autoimmune disease. ANSWER: C The HPV that causes condyloma acuminatum is almost always tr Answermitted by sexual contact. The presence of condyloma acuminatum in a child suggests sexual abuse. Hypersensitivity is not the cause of condyloma acuminatum. Genetic predisposition has nothing to do with the cause of condyloma acuminatum. Condyloma acuminatum is not an autoimmune disease. REFF: Condyloma Acuminatum, Fig. 4.18, page 126 4 25. The most common form of recurrent herpes simplex infection is termed a. herpes zoster. b. herpetic whitlow. c. herpes labialis. d. type 2 herpes. ANSWER: C Herpes labialis is the most common form of recurrent herpes simplex virus infection. Herpes zoster is caused by the varicella-zoster virus and is characterized by unilateral vesicles along a sensory nerve. Herpetic whitlow occurs when herpes simplex infection involves the fingers. Type 2 herpes simplex is most commonly associated with genital infections. Genital herpes simplex infections may be primary or recurrent. REFF: Recurrent Herpes Simplex Infection, page 127 8 26. The varicella-zoster virus causes a highly contagious disease in children termed a. shingles. b. chickenpox. c. mumps. d. measles. ANSWER: B Chickenpox is a highly contagious disease in children caused by the varicella-zoster virus. Shingles is a recurrent form of the varicella-zoster virus. It is most commonly seen in older adults and in immunocompromised individuals. Mumps is caused by a paramyxovirus and is a viral infection of the salivary glands. Measles is a highly contagious disease caused by a paramyxovirus and is seen most commonly in children. REFF: Chickenpox, page 130 9 27. The intraoral lesion seen in patients with measles is termed a. minor salivary gland swelling. b. generalized painful gingivitis. c. Koplik spots. d. candidiasis. ANSWER: C Koplik spots are erythematous macules with white necrotic centers that may occur in the oral cavity in patients with measles. Minor salivary gland swelling is not associated with measles. Generalized painful gingivitis occurs in primary herpes simplex infection. Candidiasis is one of the most common oral manifestations associated with patients who have human immunodeficiency virus (HIV). REFF: Other Viral Infections That May Have Oral Manifestations, page 132 12 28. Which virus is associated with infectious mononucleosis? a. Herpes simplex virus b. HPV c. Epstein-Barr virus d. Varicella-zoster virus ANSWER: C Infectious mononucleosis is caused by the Epstein-Barr virus. Herpes simplex virus causes primary herpetic gingivostomatitis and recurrent herpes simplex virus infections. HPV is responsible for several oral viral conditions. Varicella-zoster virus causes chickenpox and shingles. REFF: Epstein-Barr Virus Infection, page 131 11 29. Herpangina is caused by which virus? a. Herpes simplex virus b. Epstein-Barr virus c. Varicella-zoster virus d. Coxsackievirus ANSWER: D Herpangina is caused by the coxsackievirus. Herpes simplex virus causes primary herpetic gingivostomatitis and recurrent herpes simplex virus infections. Epstein-Barr virus causes mononucleosis. Varicella-zoster virus causes chickenpox and shingles. REFF: Herpangina, page 132 12 30. In testing for HIV infection, which antibody test is performed initially before the confirmatory Western blot test? a. VDRL b. ELISA (EIA) c. FTA-ABS d. CBC ANSWER: B The ELISA (enzyme-linked immunosorbent assay [also called EIA]) is the routine initial test used to identify HIV infection. When positive, this test is repeated, and positive results are confirmed with another laboratory test called the Western blot. VDRL is a plasma test performed to diagnose syphilis. FTA-ABS is the fluorescent treponemal antibody absorption test performed to diagnose syphilis. CBC is a complete plasma count and not specific for the diagnosis of HIV.
