CNUR 204: Unit 3 - Respiratory Conditions
Exam Questions and Answers with Verified
Solutions | Latest Updated 2026
Explain the patho of tuberculosis Primary infection occurs and leads to
inflammation
and lesion formation. Once inhaled, it is
ingested
by alveolar macrophages, replicates, and
kills the
host macrophage. The infection may
migrate to
lymph nodes and the blood stream.
How does TB spread? Via airborne droplets in a close, frequent,
or
prolonged exposure.
Briefly explain latent TB infection The immune system suppresses
replication before
S&S develop. A creation of granulomas
encases the
bacilli which may cause scarring.
T/F: Latent TB is infectious? False!
Which conditions may reactivate Chronic conditions (HIV, COPD, diabetes),
latent TB? corticosteroid use, cancer, aging, and
stress.
, Briefly explain active TB infection Tissues are destroyed and cavitary lesions
can also
rupture into pleural space, causing
complications.
What are four TB myths? 1. TB cannot be spread by vector
transmission
2. Latent TB is not contagious
3. Not everyone infected with TB becomes
sick
4. A positive TB skin test does not mean
you have
active disease
What are the clinical - Typically asymptomatic unless disease is
manifestations active
of TB? - Productive cough, hemoptysis, and
dyspnea
- Systematic signs include fatigue,
malaise, weight
loss, fever, and sweats
How is TB diagnosed? - Bacteriological studies (sputum smears,
cultures)
- Radiography
- TB skin test
Define multi-drug TB therapy A combination of at least three
medications to
increase effectiveness and reduce
resistance.
