Question 1

A patient with an advanced case of TB may have the following radiologic findings:
1) Bronchial tumors
2) Hyperlucent lung fields
3) Retraction of lung segments
4) Right-sided heart enlargement

A)2
B)2, 3
C)3, 4
D)1, 3, 4

3, 4

Accepted Answer

Advanced TB can cause extensive damage to the lungs, leading to retraction of lung segments and hyperlucent lung fields as well as right-sided heart enlargement due to pulmonary hypertension. Bronchial tumors are not typically associated with TB.

Question 2

Mycobacterium tuberculosis is particularly damaging to the lungs because of:&#10;A) the healing of a tubercle.&#10;B)micropulmonary emboli.&#10;C)the increased mucus production.&#10;D)the irreversible bronchospasm that it causes.

Accepted Answer

Mycobacterium tuberculosis causes the formation of tubercles in the lungs. As these tubercles heal, they can leave behind scar tissue that can lead to severe lung damage over time.

Question 3

What medication is used to treat a person who has converted to a positive TB skin test but does not have active disease?&#10;A) Virazole&#10;B)Isoniazid&#10;C)Rifampin&#10;D)Tetracycline

Accepted Answer

Isoniazid is the medication commonly used to treat latent tuberculosis infection, which occurs when a person has a positive TB skin test but does not have active disease. The medication is typically given daily for 9 months to effectively treat the infection and prevent the development of active TB disease in the future.

Question 4

The preferred stain that is used to identify the TB organism is called:&#10;A) Gram stain.&#10;B)Fluorescent acid-fast stain.&#10;C)Ziehl-Neelsen.&#10;D)Gentian violet.

Accepted Answer

The answer of The preferred stain that is used to...

Question 5

Nontuberculous mycobacteria such as Mycobacterium avium and Mycobacterium kansasii are associated with which of the following diseases?&#10;A) COPD&#10;B)Bronchiectasis&#10;C)Status asthmaticus&#10;D)Cystic fibrosis

Accepted Answer

The answer of Nontuberculous mycobacteria such as Mycobacterium avium and...

Question 6

Risk factors predisposing a person to TB include all of the following EXCEPT:&#10;A) having HIV/AIDS.&#10;B)being immunosuppressed.&#10;C)African American or Hispanic heritage.&#10;D)malnutrition.

Accepted Answer

African American or Hispanic heritage is not a recognized risk factor for TB. However, individuals from low-income groups and those living in crowded or unsanitary conditions are at higher risk for TB, which may disproportionately affect African American and Hispanic populations. The other options listed (having HIV/AIDS, being immunosuppressed, and malnutrition) are all recognized risk factors for TB.

Question 7

Mycobacterium tuberculosis is most readily transmitted through:&#10;A) drinking milk from or the milking of infected cows.&#10;B)shaking hands and then rubbing your eye.&#10;C)coughing.&#10;D)accidental direct inoculation.

Accepted Answer

Mycobacterium tuberculosis is primarily transmitted through the air when an infected person coughs, sneezes, speaks, or sings. The bacteria can be spread through droplets that are generated when an infected person exhales.

Question 8

A patient who has an uncontrolled tuberculosis infection will show all of the following signs EXCEPT:&#10;A) weight loss.&#10;B)high fever.&#10;C)bloody sputum.&#10;D)night sweats.

Accepted Answer

Patients typically will have a low-grade fever with this infection. All of the other listed items, and others, will be found.

Question 9

The most effective medication used to treat a TB infection is:&#10;A) rifampin.&#10;B)penicillin.&#10;C)streptomycin.&#10;D)isoniazid.

Accepted Answer

The answer of The most effective medication used to treat...

Question 10

Your patient has been found to have tuberculosis (TB) in several organs of the body. What term is used to describe this situation?&#10;A) Primary TB&#10;B)Postprimary TB&#10;C)Disseminated TB&#10;D)Multiorgan TB

Accepted Answer

Disseminated TB is the term used to describe tuberculosis that has spread from the lungs to other organs of the body, such as the brain, liver, or kidneys. Primary TB typically only affects the lungs, while postprimary TB can occur when the initial infection reactivates after a period of dormancy. Multiorgan TB is not a commonly used term.

Question 11

When a person has TB spread through the body, it is found in all of the following EXCEPT:&#10;A) upper lobes.&#10;B)kidneys.&#10;C)brain.&#10;D)lower lobes.

Accepted Answer

The answer of When a person has TB spread through...

Question 12

Your patient has postprimary TB. What are the major pathologic or structural changes associated with it?
1) Cavity formation
2) Laryngeal edema
3) Dilated and distorted bronchi
4) Fibrosis of lung parenchyma

A)2, 3
B)3, 4
C)1, 2, 3
D)1, 3, 4

Accepted Answer

The answer of Your patient has postprimary TB. What are...

Question 13

A negative tuberculin test would be demonstrated by an induration (wheal) of what size?&#10;A) 4 mm or less&#10;B)6 mm or less&#10;C)8 mm or greater&#10;D)10 mm or greater

Accepted Answer

The answer of A negative tuberculin test would be demonstrated...
