Compression Quiz Flashcards
Which of the following is NOT a major pathway for fluid to travel through the body?
Edema
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?
Interstitial spaces where fluid and nutrients leave the capillary beds
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?
90%
What is the significance of the removal of proteins along with the excess fluid from the interstitial spaces by the lymphatic system?
The removal of proteins along with excess fluid is an essential function, without which we could die within about 24 hours
Which of the following is NOT a function of the lymphatic system?
Regulation of fluid balance through the transport of blood
Which of the following statements is true regarding the lymphatic system?
The lymphatic system is a one-way system
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?
Gravity
Musculoskeletal Contractions
Respiratory pressure changes
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?
The lymph nodes; they remove foreign substances and fight infection
The composition of the lymphatic system’s “gel matrix” enables what to occur?
Absorption of more fluid than in normal state
Localized acute tissue trauma will cause edema that is characterized by which of the following?
Low protein content
which of the following metabolic disease states can cause increased capillary pressure due to a venous obstruction from pooling of blood in the veins?
Congestive heart failure
What is the only physiological mechanism to remove proteins from the tissues?
The lymphatic system
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?
The rest component should be very brief to maintain mobility of the part and make the reabsorption of fluids easier
Why is the application of ice to an edematous area the treatment of choice in some situations?
It can minimize accumulation of fluid when used appropriately
When would elevation of a body part be contraindicated and inappropriate as a potential remedy to assist in edema reduction?
If the limb is ischemic
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?
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
What effect does therapeutic exercise have on lymphatic flow
It enhances venous and lymphatic flow
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?
Water exerts compression on the immersed body part, with the distal portion of the limb receiving the greatest pressure
Which of the following statements is the most accurate regarding edema assessment techniques?
Both water displacement and calculated volume for the upper extremity are acceptable, but they are not interchangeable
Which of the following signs would be consistent with venous edema but now with acute edema?
Loss of normal contours of the leg
