Compression Quiz

Question 1

Which of the following is NOT a major pathway for fluid to travel through the body?

Answer 1

Edema

Question 2

The heart is responsible for pumping fluid through an extensive network of vessels divided into an arterial side and a venous side. If the arterial side were impaired, which of the following structures/systems would not be working efficiently?

Answer 2

Interstitial spaces where fluid and nutrients leave the capillary beds

Question 3

In a normal state, how much of the fluid that is filtered out of the capillary bed on the arterial side is reabsorbed on the venous side?

Answer 3

90%

Question 4

What is the significance of the removal of proteins along with the excess fluid from the interstitial spaces by the lymphatic system?

Answer 4

The removal of proteins along with excess fluid is an essential function, without which we could die within about 24 hours

Question 5

Which of the following is NOT a function of the lymphatic system?

Answer 5

Regulation of fluid balance through the transport of blood

Question 6

Which of the following statements is true regarding the lymphatic system?

Answer 6

The lymphatic system is a one-way system

Question 7

Which of the following acts as an extrinsic pump in the lymphatic system, similar to the function that the heart fulfills in the circulatory system?

Answer 7

Gravity
Musculoskeletal Contractions
Respiratory pressure changes

Question 8

The lymphatic system normally transports approximately 2 to 2.5 liters of fluid per day and 80 to 200 grams of protein back to the circulatory system. What structures filter the lymphatic fluid, and why?

Answer 8

The lymph nodes; they remove foreign substances and fight infection

Question 9

The composition of the lymphatic system’s “gel matrix” enables what to occur?

Answer 9

Absorption of more fluid than in normal state

Question 10

Localized acute tissue trauma will cause edema that is characterized by which of the following?

Answer 10

Low protein content

Question 11

which of the following metabolic disease states can cause increased capillary pressure due to a venous obstruction from pooling of blood in the veins?

Answer 11

Congestive heart failure

Question 12

What is the only physiological mechanism to remove proteins from the tissues?

Answer 12

The lymphatic system

Question 13

RICE therapy has been the intervention of choice since the 1950s in the first 24 to 72 hours after injury. The acronym stands for Rest, Ice, Compression, and Elevation of the affected body part. How long should the rest component last and why?

Answer 13

The rest component should be very brief to maintain mobility of the part and make the reabsorption of fluids easier

Question 14

Why is the application of ice to an edematous area the treatment of choice in some situations?

Answer 14

It can minimize accumulation of fluid when used appropriately

Question 15

When would elevation of a body part be contraindicated and inappropriate as a potential remedy to assist in edema reduction?

Answer 15

If the limb is ischemic

Question 16

Compression increases the hydrostatic pressure in the tissues, decreasing the ultra-filtration out of the damaged capillaries and increasing absorption of fluid by the veins and fluid and proteins by the lymphatic vessels. What is the recommended pressure range for intermittent compression devices, and why?

Answer 16

Below 30 to 40 mm Hg, due to inaccurate control of actual pressure created by the devices or the potential damage to the superficial lymphatic vessels

Question 17

What effect does therapeutic exercise have on lymphatic flow

Answer 17

It enhances venous and lymphatic flow

Question 18

Of what potential benefit would an aquatic exercise program be for individuals with leg swelling of non-metabolic origin and who have a stable cardiovascular system, and why?

Answer 18

Water exerts compression on the immersed body part, with the distal portion of the limb receiving the greatest pressure

Question 19

Which of the following statements is the most accurate regarding edema assessment techniques?

Answer 19

Both water displacement and calculated volume for the upper extremity are acceptable, but they are not interchangeable

Question 20

Which of the following signs would be consistent with venous edema but now with acute edema?

Answer 20

Loss of normal contours of the leg
