Tuberculosis (TB) UPDATED Actual Exam
Questions and 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 - CORRECT 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 - CORRECT 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 - CORRECT 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 - CORRECT 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 - CORRECT 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
D. To determine if this is a primary or secondary infection - CORRECT ANSWER- ✔✔6. C.
If the lesions are large enough, the chest x-ray will show their presence in the lungs. Sputum
culture confirms the diagnosis. There can be false-positive and false-negative skin test results.
A chest x-ray can't determine if this is a primary or secondary infection.
7. A chest x-ray should a client's lungs to be clear. His Mantoux test is positive, with a 10mm
if induration. His previous test was negative. These test results are possible because:
A. He had TB in the past and no longer has it.
