Tumors

Question 5

The rate of fluid formation is dictated by what law?

Answer 5

Starling’s Law

Question 6

The rate of fluid formation is dictated by Starling’s Law. What determines the movement of fluid? (2)

Answer 6

1 - Hydrostatic pressure and osmotic pressure BALANCE in pleural space and pulmonary capillary bed

2 - PERMEABILITY of pleural membrane

Question 7

Normal level of fluid present in pleural space

Answer 7

10 mL

Question 8

Pathology of Serofibrinous/ serosanguineous pleurisy with pleural effusion

Answer 8

Fluid formation exceeds clearance leading to accumulation –> inflammation –> increase pleural space permeability with increase proteinaceous fluid formation –> obstruction of lymphatic absorption

Answer 14

Friction rubs

Question 15

In infants, this is heard instead of decreased breath sounds

Answer 15

Bronchial breathing

Question 16

Radiographic exam result will show

Answer 16

Homegeneous density obliterating normal markings of lungs

Question 17

In radiographs, small effusions is seen to cause

Answer 17

Obliterations of ostophrenic or cardiophrenic angles or

Widening of interlobar septa

Question 18

Answer 18

Supine and upright

Decubitus position

Question 23

In malignancy, rheumatoid disease and TB, the glucose level is usually

Answer 23

<60 mg/dL

Question 24

These findings suggest TB (2)

Answer 24
