1. 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. 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. 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.
4. 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.
5. 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.
6. 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: 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. 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.: 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 client's blood and x-ray
results may stay negative. It doesn't mean the infection has advanced to the active stage. Because his x-ray is negative,
he should be monitored every 6 months to see if he develops changes in his x-ray or pulmonary examination. Being a
seroconverter doesn't mean the TB has gotten into his bloodstream; it means it can be detected by a blood test.
