1

What is underlying pathophys of ARDS?
-what will CXR look like?

Damage to endothelial cells lining the pulm caps.
-results in leakage of fluids into alveoli.
-CXR will show "white out" of the lungs.

2

Alveolar wall destruction
-which disease?

emphysema

3

aneurysmal dilations
-usually have absent what?

internal elastic lamina.

4

Cardiac tissue conduction velocity
-order?
-mnemonic:

Park At Ventura Ave.
-purkinje system = fastest
-atrial muscle
-ventricular muscle
-AV node = slowest

5

Which chamber are SA and AV node located?

RA

6

Conduction speed of atrial muscle vs ventricular muscle.
-which one faster?

atrial muscle faster than ventricular muscle.

7

Paget disease of bone
-most often associated w/which bone tumor?

osteosarcoma.

8

Age distribution in osteosarcoma?

bimodal.

9

radiological findings in osteosarcoma:

-areas of mixed lysis & sclerosis = radioopaque & radiolucent areas.
-periosteal elevation.
-reactive new bone formation.
-lifting of cortex.

10

Osteophytes
-RA or osteoarthritis?

osteoarthritis

11

Trabecular bone
-aka?
-damaged preferentially in which disease?

-spongy, cancellous.
-osteoporosis.

12

globus hystericus
-what is it?

"lump in your throat".

13

karyorrhexis
-what is it?

nuclear fragmentation - part of apoptosis.
-get 180 bp fragments.

14

Blurred vision: think what mechanism?

-think a ciliary muscle/lens issue, NOT a pupillary size issue!

15

Pleiotropy

Impact a single gene has on multiple phenotypes.

16

tumor cell w/round nuclei and prominent lipid vacuoles.

Burkitt lymphoma

17

t(12;21): which disease?

ALL
-better prognosis.

18

IL-1 primarily released by which cell?

macros

19

TNF-alpha primarily released by which cell?

macros

20

GM-CSF
-stim prod of which cells?

granulocytes + monocytes

21

What can cause dissociation of cadherins?

Removing Ca from extracellular fluid. Leads to loss of cell-to-cell adhesion.
-Cadherin intercellular interactions are Ca dependent.

22

In post & ant dislocations of knee (so ACL/PCL injuries), which nerve or vessel is most likely to be injured?

Popliteal artery
*tibial n. in similar location but not as susceptible to this type of injury like pop. artery is.
*popliteal vein same location but superficial to artery. Also not as likely to be injured in this kind of injury.

23

Psych: reflection is most similar to what other technique?

summarization

24

Psych: facilitation
-what is it?

Encouraging the pt to talk more: "tell me how your drinking increased".

25

What changes does cocaine cause to your nose area?

-atrophic nasal mucosa.
-chronic nasal discharge.
-thinning of nasal septum.
-oropharyngeal ulcers.

26

Hay fever
-what is it?

Seasonal form of allergic rhinitis.
-provoked by pollen from plants.

27

mast cell.

28

Long thoracic nerve
-which nerve roots?

C5-C7

29

Is there bicarb in sweat?

not really.

PTSD
-by definition how long has it been going on?
-what do you call it if it hasn't been going on that long?

PTSD > 1 month.
< 1 month (but > 3 days) = acute stress disorder.
