The causative agent for tuberculosis is _ _ which is transmitted through __ __ from persons that undergoing __ infection

Mycobacterium tuberculosis

airborne droplets

active

2

Tuberculosis occurs more frequently with: (4)

1. Persons living in crowded conditions
2. People with immunodeficiency or HIV infection
3. People with chronic alcoholism, malnourished
4. People who are suffering from chronic disease which can lead to chronic inflammation and decreased immune function

3

When we first inhale that mycobacterium tuberculosis in our lung, we have our __ __ getting ready to start

primary infection

4

When we get that bacteria in there, our body is going to have an __ __

inflammatory response

5

IF we have __ __, if we have __ __ __ , our body is going to try to fight it somewhat

high resistance; normal immune function

6

We are going to have our delayed __ __ __ reaction kick in which is going to show as __ when we get that PPD test

type IV hypersensitivity
positive

7

The __ are going to go to __ __ which are going to initiate that type IV immune response

bacilli ; lymph nodes

8

For those with __ __ and good __ __, there are going to be __ that form as the body tried to fight that M. tuberculosis

high resistance; immune function
tubercles

9

When that tubercle forms, what kinds of things are going to be in there? (3)

1. There's going to be cells that are dying, some necrosis
2. Inflammatory products
3. Body's leukocytes

10

We have difficulty trying to totally eradicate it from the body. Eventually we will form __ and wall off the __ . This is called a __ __. Our body is going to make new types of __ __ in order to form __ and wall off the bacteria.

granulomas; bacteria ; Ghon complex
epithelial cells; granulomas

11

If we stay healthy and are not immunocompromised, then we are going to successfully have it walled off. If we have immune suppression, then that walled off bacteria can __ __ and break forth again through these complexes leading to a __ __ or __.

come back; secondary infection; reinfection

12

If we have __ __ or __ __ __, we are initially infected by that tuberculosis then we can have __ occur

low resistance; poor immune function ; cavitation

13

We are undergoing __ __ when under cavitation

active infection

14

Cavitation can also be seen in __ __ or __

secondary infection; reinfection

15

When we get to that active infection stage, that is when we can:

spread it to other people!

16

The bacilli can remain dormant for years and then just come out again when we have __ __ __

low immune function

17

In active infection, the organism is __ and forming a large area of __

multiplying; necrosis

18

This is causing __ __ __ of lungs or __

large open areas; cavitations

19

Cavitations promote spreading of the other parts of the lung such as the __ __ or even through the __ and to other parts of the body

pleural cavity; bloodstream

20

__ __ or __ __ will show some cavitations

Radiographic findings; x rays

21

During active infection, we will have a __ __ __

positive sputum culture

22

If we have a patient with TB, they are going to be in the _ __ __ and we will be wearing our ___ ___

negative pressure room; N-95 masks

27

Person has to go get a __ _ __ to see if they have any type of active infection

chest x ray

28

We can check:
1
2
3
to determine if they have an active infection

3. nucleic amplification of that sputum

29

If person has an active infection, we have to put them on __ __ __ __
