Module 2 ACOLS

Question 1

Diffusion is the migration of particles from higher to lower

Answer 1

T

Question 2

Osmosis is the movement of water molecules that occur in one direction across a semi permeable membrane

Answer 2

T

Question 3

Colloid osmotic pressure of the plasma (COPpl) is the force of proteins in the blood to hold water

Answer 3

T

Question 4

Blood pressure in the arteries is higher than blood capillary pressure

Answer 4

T

Question 5

In healthy individuals the colloid osmotic pressure of proteins located in the interstitium (COPip) is greater than the Colloid osmotic pressure of the plasma (COPpl)

Answer 5

F - less

Question 6

The precapillary sphincter is innervated by the sympathetic portion of the Autonomic Nervous System (ANS)

Answer 6

T

Question 7

The precapillary sphincter dilates = Less blood into capillaries —> less volume = decreased blood capillary pressure (BCP)

Answer 7

F - more blood, more volume, increased BCP

Question 8

Starlings Law states that the average Blood capillary pressure (BCP) equals the average Colloid Osmotic Pressure of the plasma proteins (COPpl)

Answer 8

T

Question 9

Complete Decongestive Therapy (CDT) attempts to restore normal diffusion distance and prevent re-accumulation of fluid

Answer 9

T

Question 10

The Functional Reserve (FR) of the lymphatic system enables the lymphatic system to respond to an increase in lymph fluid volume with and increase in Lymph Time Volume (LTV)

Answer 10

T

Question 11

if the normal diffusion distance in the tissues between the cells and the blood capillary increases (swelling present)

Answer 11

The local immune response in the tissue cells is compromised
The nutritional supply to the cells will suffer
Patient is prone to frequent infections

Question 12

What is true about diffusion distance

Answer 12

Swelling increases Diffusion Distance
If swelling is present immune response is low/ compromised and nutritional supply suffers
Compression decreases diffusion distance

Question 13

When the precapillary sphincter located at the arteriole contracts

Answer 13

• less blood enters into the capillaries
• volume will decrease and the blood capillary pressure will also decrease
• less filtration occurs

Question 14

What upsets The equilibrium of Starlings Law?

Answer 14

Passive hyperemia

Active hyperemia

Question 15

If a healthy lymphatic system is overwhelmed and the lymphatic loaf of water exceeds the transport capacity (TC) with a Lymph Time Volume (LTV) maxed out is called…

Answer 15

Dynamic Insufficiency

Question 16

Define: Hypoproteinemia

Answer 16

Abnormal deficiency of the amount of protein in the blood

Question 17

Mechanical insufficiency

Answer 17

Transport capacity drops below the normal amount of lymphatic load, low volume insufficiency

Question 18

Filtration

Answer 18

Transport of a solution through a filter, provided the membrane is permeable

Question 19

Lymphedema

Answer 19

Abnormal accumulation of protein rich fluid in the tissue

Question 20

Functional reserve

Answer 20

Back up of lymphatic system - amount of compensation

Question 21

Edema

Answer 21

Abnormal accumulation of water in the tissue

Question 22

Dynamic insufficiency

Answer 22

Healthy lymphatic system is overwhelmed, Hugh volume insufficiency

Question 23

Transport Capacity

Answer 23

The maximum amount of lymph transported with the lymphatic system working as hard as possible in a given length of time

Question 24

Lymph time volume

Answer 24

Amount of lymph transported in a unit of time

Question 25

Reabsorption

Answer 25

Process by which water is reabsorbed from the tissues back into the venous end of the blood capillary
