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✔C
This test would be classed as negative. A 5 mm 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.
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✔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.
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) super infection
d) tertiary infection - answer✔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✔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.

A
Chest x-ray

Mantoux test
