Tuberculosis (TB) Exam Questions With
Correct Answers

1. The right forearm of a client who had a purified protein derivative (PPD) test for tuberculosis

is reddened and raised about 3mm where the test was given. This PPD would be read as having

which of the following results?

A. Indeterminate

B. Needs to be redone

C. Negative

D. Positive - answer✔1. C. This test would be classed as negative. A 5mm raised area would be

a positive result if a client was HIV+ or had recent close contact with someone diagnosed with

TB. Indeterminate isn't a term used to describe results of a PPD test. If the PPD is reddened and

raised 10mm or more, it's considered positive according to the CDC.

2. A client with primary TB infection can expect to develop which of the following conditions?

A. Active TB within 2 weeks

B. Active TB within 1 month

C. A fever that requires hospitalization

D. A positive skin test - answer✔2. D. A primary TB infection occurs when the bacillus has

successfully invaded the entire body after entering through the lungs. At this point, the bacilli are

walled off and skin tests read positive. However, all but infants and immunosuppressed people

will remain asymptomatic. The general population has a 10% risk of developing active TB over

their lifetime, in many cases because of a break in the body's immune defenses. The active stage

shows the classic symptoms of TB: fever, hemoptysis, and night sweats.

3. A client was infected with TB 10 years ago but never developed the disease. He's now being

treated for cancer. The client begins to develop signs of TB. This is known as which of the

following types of infection?

A. Active infection

B. Primary infection

C. Superinfection

D. Tertiary infection - answer✔3. A. Some people carry dormant TB infections that may develop

into active disease. In addition, primary sites of infection containing TB bacilli may remain

inactive for years and then activate when the client's resistance is lowered, as when a client is

being treated for cancer. There's no such thing as tertiary infection, and superinfection doesn't

apply in this case.

A client has active TB. Which of the following symptoms will he exhibit?

A. Chest and lower back pain

B. Chills, fever, night sweats, and hemoptysis

C. Fever of more than 104*F and nausea

D. Headache and photophobia - answer✔4. B. Typical signs and symptoms are chills, fever,

night sweats, and hemoptysis. Chest pain may be present from coughing, but isn't usual. Clients

with TB typically have low-grade fevers, not higher than 102*F. Nausea, headache, and

photophobia aren't usual TB symptoms.

Which of the following diagnostic tests is definitive for TB?

A. Chest x-ray

B. Mantoux test

C. Sputum culture

D. Tuberculin test - answer✔5. C. The sputum culture for Myobacterium tuberculosis is the only

method of confirming the diagnosis. Lesions in the lung may not be big enough to be seen on x-

ray. Skin tests may be falsely positive or falsely negative.

A client with a positive Mantoux test result will be sent for a chest x-ray. For which of the

following reasons is this done?

A. To confirm the diagnosis

B. To determine if a repeat skin test is needed

C. To determine the extent of the lesions
