TUBERCULOSIS EXAM PREP 2026 WITH
ACTUAL QUESTIONS AND VERIFIED CORRECT
ANSWERS GRADED A+
◉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
D. To determine if this is a primary or secondary infection . 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.
B. He was successfully treated for TB, but skin tests always stay
positive.
C. He's a "seroconverter", meaning the TB has gotten to his bloodstream.
D. He's a "tuberculin converter," which means he has been infected with
TB since his last skin test. . Answer: 7. D. A tuberculin converter's skin
test will be positive, meaning he has been exposed to an infected with
TB and now has a cell-mediated immune response to the skin test. The
