Accepted Answer

The Centers for Disease Control and Prevention (CDC) has published guidelines for the prevention of tuberculosis in dental health care facilities. These guidelines provide recommendations for infection control practices, such as appropriate use of personal protective equipment, management of patients with suspected or confirmed tuberculosis, and implementation of respiratory protection programs.

Question 2

Which of the following human herpesviruses causes hairy leukoplakia, an infection of the tongue?&#10;A)Type 1&#10;B)Type 2&#10;C)Type 3&#10;D)Type 4

Accepted Answer

Human herpesvirus type 4, also known as Epstein-Barr virus (EBV), causes hairy leukoplakia, which is a white tongue lesion that cannot be scraped off. Hairy leukoplakia is typically seen in HIV-positive individuals, but it can also occur in individuals with other immunocompromised conditions.

Question 3

Some strains of which of the following bacteria are known as &#34;flesh-eating&#34; bacteria?&#10;A)Mycobacterium tuberculosis&#10;B)Staphylococcus aureus&#10;C)Corynebacterium diphtheriae&#10;D)Streptococcus pyogenes

Accepted Answer

Streptococcus pyogenes, also known as Group A Streptococcus, can cause necrotizing fasciitis, which is commonly referred to as "flesh-eating" disease.

Question 4

A report has shown that two cancer-weakened patients acquired oral infection with the bacterium _____ that originated from dental unit water.&#10;A)Staphylococcus aureus&#10;B)Streptococcus mutans&#10;C)Pseudomonas aeruginosa&#10;D)Candida albicans

Accepted Answer

The bacterium that originated from dental unit water and caused the oral infection in two cancer-weakened patients is most likely Pseudomonas aeruginosa. This bacterium is commonly found in water and can cause infections in immunocompromised individuals, such as cancer patients. Staphylococcus aureus and Streptococcus mutans are common oral bacteria but are not typically associated with infections originating from dental unit water. Candida albicans is a fungal infection and not a bacterium.

Question 5

Which of the following is a systemic disease that commonly produces lesions in the mouth?&#10;A)Chickenpox&#10;B)Tuberculosis&#10;C)Legionnaire's disease&#10;D)Influenza

Accepted Answer

The answer of Which of the following is a systemic...

Question 6

Which of the following diseases may produce palatal petechiae, widespread erythema (reddening) of the oral mucosa, and swelling of the uvula?&#10;A)Infectious mononucleosis&#10;B)Influenza&#10;C)Herpes labialis&#10;D)Legionnaire's disease

Accepted Answer

Palatal petechiae, widespread erythema of the oral mucosa, and swelling of the uvula are all common symptoms of infectious mononucleosis. None of the other diseases listed typically produce these specific symptoms.

Question 7

Rheumatic heart disease occurs in a small percentage of those previously infected with:&#10;A)Mycobacterium tuberculosis.&#10;B)Staphylococcus aureus.&#10;C)Corynebacterium diphtheriae.&#10;D)Streptococcus pyogenes.

Accepted Answer

Rheumatic heart disease is a complication that can occur after infection with Streptococcus pyogenes, the bacterium that causes strep throat.

Question 8

What microbe causes denture stomatitis?&#10;A)Streptococcus mutans&#10;B)Herpes simplex virus&#10;C)Candida albicans&#10;D)Streptococcus pyogenes

Accepted Answer

Candida albicans is the microbe responsible for causing denture stomatitis, a fungal infection that occurs in the mouth of denture wearers. Streptococcus mutans and Streptococcus pyogenes are bacteria that can cause dental caries and strep throat, respectively. Herpes simplex virus can cause cold sores or genital herpes, but not denture stomatitis.

Question 9

Which of the following types of respiratory infections is usually caused by inhaling or aspirating contaminated water?&#10;A)Chickenpox&#10;B)Infectious mononucleosis&#10;C)Legionnaire's disease&#10;D)Influenza

Accepted Answer

Legionnaire's disease is caused by inhaling contaminated water droplets that contain Legionella bacteria. It is a type of pneumonia that can be serious and even fatal in some cases. Chickenpox and infectious mononucleosis are caused by viruses, while influenza is caused by a different type of virus that is transmitted through respiratory droplets. None of these infections are typically associated with contaminated water.

Question 10

Which of the following is a respiratory disease that can be screened for through use of the Mantoux test or purified protein derivative test?&#10;A)Strep throat&#10;B)Tuberculosis&#10;C)HIV disease&#10;D)Syphilis

Accepted Answer

The Mantoux test or purified protein derivative test is used to screen for tuberculosis, a respiratory disease caused by the bacterium Mycobacterium tuberculosis. Strep throat is a bacterial infection of the throat, HIV disease is a viral infection that attacks the immune system, and syphilis is a sexually transmitted bacterial infection. None of these diseases can be screened for using the Mantoux test.
