Tuberculosis (TB) Exam Questions with
100% Correct Answers | Rated A+
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 - ✔✔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 - ✔✔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 - ✔✔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 - ✔✔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 - ✔✔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
