Q

Why is radiation and chemotherapy weakening to the body?

Q

What is stage IV cancer growth?

A

It has spread beyond the lymph and lungs

21
Q

What is a pneumothorax (collapsed lung)?

A

When air leaks into the space between the lung and chest wall, the air pushes on the outside of the lung and causes it to collapse.

22
Q

How can pneumothorax be fixed?

A

With a chest tube to drain the air and allow lung to recruit and expand.

23
Q

What is the manifestation of pneumothorax on a CXR?

A

There is a white line seen blending with lung tissue and this line indicated collapsed lung due to no lung marking on the left side lower to mid lobe.

24
Q

What is a history of pneumothorax a contraindication for?

A

Scubadiving

25
Q

Why would scuba diving be dangerous for someone with a history of pneumothorax?

A

This is due to how deep they go in the ocean and the water pressure because the deeper they go the higher the pressures which could worsen a pneumothorax or even worst; complete lung collapse. Also because of the increased likelihood of pneumothorax occurring while you are diving.

26
Q

What is another risk with scuba diving?

A

Atelectasis

27
Q

What would be clear evidence of fluid overload in the cardio/pulmonary circuit be indicative of?

A

Long term effects of ESRD on the lungs and heart

28
Q

What is the primary type of pneumothorax?

A

It has no clear etiology and occurs in the absence of substantial lung disease.

29
Q

What is the secondary type of pneumothorax?

A

Lung disease already present

30
Q

What is a tension pneumothorax a result of?

A

When the air volume in the chest significantly increases, a one-way valve forms.

31
Q

What is the percentage of nitrogen gas when someone has a pneumothorax and what is the needed amount of oxygen in order to push it out?

A

78% N2 and 100% O2 needed

32
Q

Is nitrogen very soluble in aqueous solution/ blood?

A

No it is not soluble

33
Q

Where is the majority of a whale’s surfactant found?

A

In its blowhole

34
Q

*Why is lung cancer not painful and asymptomatic until stage III & IV?

A

Due to fibers below vocal chord having no pain receptors.

35
Q

*The entire lung except for where has no pain receptors?

A

Parietal pleurae (which is highly sensitive to pain) ex: baseball hit to the ribs is pleuritic pain

36
Q

*What is a similarity in patients with pleural effusion or atelectasis?

A

They will have the same diffuse white pattern in the hemithorax.

37
Q

*What is another similarity in patients with pleural effusion or atelectasis?

A

left pleural effusion and atelectasis the mediastinum will be pulled to the same side of the atelectasis.

38
Q

*What is a difference in patients with pleural effusion or atelectasis?

A

Rib spaces will widen with a massic pleural effusion and rib spaces will narrow for atelectasis.

39
Q

*What is the pattern of growth for cancer cells?

A

Cancer cells grow uncontrollably

40
Q

*Who is Henrietta lack and what is she known for?

A

An ovarian cancer patient who donated her cancer cells to research and for many years was the only human cell line able to reproduce indefinitely.

41
Q

*What are today’s proteins from these incredible cells called?

A

Hela Cells

42
Q

*What are Hela Cells used to study?

A

The effects of toxins, drugs, hormones, and viruses on the growth of cancer cells without experimenting on humans.

43
Q

*What is cancer staging?

A

The process of determining how much cancer is in the body & where it is located. It describes the severity of an individual’s cancer based on the magnitude of the original (primary) tumor as well as the extent cancer has spread in the body.

44
Q

*What is stage I cancer?

A

Early Stage (or localized cancer) – a small, invasive mass or tumor has been found, with no spread to lymph nodes or other tissue.

45
Q

*What is stage II cancer?

A

Localized – cancer has started to affect nearby tissue and the mass may have grown in size. Spread to lymph nodes near the mass.

46
Q

*What is stage III cancer?

A

Regional Spread – cancer affects more surrounding tissue. The mass may have grown in size and spread to distant lymph nodes away from the mass.

47
Q

*What is stage IV cancer?

A

Distant Spread or “advanced” or “metastatic”– cancer has spread to other tissue or organs beyond the region where it originates.

48
Q

*What is a positive sign of pneumothorax?

A

A white line with no lung markings

49
Q

*What are two optional treatments for pneumothorax?

A

1) “Conservative way” through administration of 100% oxygen. This method hastens the absorption of the pneumothorax, theory behind is that oxygen therapy reduces the partial pressure of nitrogen in the inspired gas & alveolus compared with the pleural cavity and the diffuse gradient for nitrogen accelerates pneumothorax resolution.

2) Inserting chest tube. The goal of treatment is the removal of air from the pleural cavity and preventing its recurrence.
