TB Exam Newest 2025/2026 Complete Exam Questions and Correct Answers (Verified
Answers)
Can TB be transmitted to other parts of the body yes- the meninges, kidneys,bones, and
lymph nodes
What causes the infection M Tuberculosis is an acid-fast aerobic rod that grows slowly and is
sensitive to heat and ultraviolet light.
What's associated with TB associated with poverty, malnutrition, overcrowding,
substandard housing, and inadequate health care.
How's TB spread airborne transmission, droplet nuclei through talking, coughing, sneezing,
laughing, or singing. Larger droplets settle; smaller droplets suspended in the air and are
inhaled
Risk Factors for Tuberculosis Close contact with someone who has active TB. compromised
status, substance abuse, inadequate health care, impoverished; minorities, children <15 year
and young adults between ages 15 and 44 year
What are other risk factors Preexisting medical conditions or special treatment like
diabetes, chronic renal failure, malnourishment, selected
malignancies, hemodialysis, transplanted organ, gastrectomy, jejunoileal bypass
What are more risk factors Immigration from high incidence countries like Asia, Africa, Latin
America, Caribbean, Institutionalization eg, long-term care facilities, psychiatric facility, prisons
poor living conditions
What are risk factors specific to healthcare workers performing high-risk activities:
administration of aerosolized pentamidine and other medications, sputum induction
procedures, bronchoscopy,
, suctioning, coughing procedures, home health care compromised pt., administering anesthesia
and
related procedures intubation or suctioning
TB patho inhale bacteria, go to alveoli, multiply, then transmitted to kidneys, bones,
cerebral cortex and other areas of lungs like upper lobes= body reacts with inflammatory
response
TB patho continued phagocytes and other immune system functions eat bacteria and
normal tissue, =results in accumulation of exudate in alveoli, causing bronchopneumonia
When does initial infection occur 2-10 wks after exposure, doesn't test positive on PPD test
for 3-10 weeks after infection
Granuloma formation per CDC LATENT The cells form a barrier shell, called a granuloma,
that keeps the bacilli contained and under control (LTBI).
Granuloma formation LATENT Granulomas, new tissue masses of live and dead bacilli,
are surrounded by macrophages, which form a protective
wall. This forms a mass and then forms a collagenous scar, bacteria become dormant at this
point. No further progression of disease, the mass formed is tubercule
What about after initial exposure and infection? the tubercule previously formed may
ulcerate, active disease may develop because of a compromised or inadequate immune
response. Active disease also may occur with reinfection & activation of dormant bacteria. The
ulceration releases material into bronchi, further spread occurs
How else do tubercule progress disease and cause problems Then the ulcerated tubercle
heals and forms scar tissue. causes the infected lung to become more inflamed, causes further
development of bronchopneumonia and tubercle formation. This causes long remissions and
reactivation of activity
