PCM III- Compression Exam Questions with Correct Answers
(Grade A+)
Question 1: normal circulation
Answer: heart -> arteries -> capillaries -> veins -> heart
Question 2: primary force of venous flow
Answer: muscle contraction, especially calves
Question 3: what prevents backflow
Answer: venous valves
Question 4: hydrostatic pressure
Answer: pushes fluid out
Question 5: osmotic pressure
Answer: due to presence of plasma proteins, pulls fluid back in
Question 6: balance between hydrostatic and osmotic
Answer: more fluid is pushed out than brough back in
Question 7: excess fluid is taken by
Answer: lymphatic capillaries
Question 8: lymphatic system
Answer: large netwrk of vessels and nodes throughout the body
Question 9: fluid flows into the lymphatic system due to
Answer: high concentration of proteins in lymphatic vessels
Question 10: lymphatic system dumps into

, Answer: subclavian veins
Question 11: compression
Answer: an inward-directed mechanical force that increases external pressure on the body or body-part
Question 12: physiologic effects of external compression
Answer: 1. improves venous and lymphatic circulation 2. limits the shape and size of soft tissue 3. increases
tissue temperature
Question 13: how does compression increase venous and lympatic circulation
Answer: increases hydrostatic pressure in interstitial space limits out flow of fluid from vessels and/or
pushes fluid back into vessels keeps fluid in the circulatory system where it can circulate
Question 14: compression phase of intermitten compression
Answer: fluid moves proximally
Question 15: relaxed phase on intermittent compression
Answer: allows for refilling of venous and lymphatic vessels
Question 16: sequential multi-chamber
Answer: best type because it compresses distally and then moves proximally
Question 17: how does compression influence soft tissue
Answer: acts as a second skin during new tissue formation, less extensible so controls the soft tissue better
Question 18: how does compression increase tissue temperature
Answer: insulation for the area it's applied prevents loss of body heat warmth not due to compression
directly
Question 19: edema
Answer: swelling caused by excess fluid trapped in your body's tissue
Question 20: causes of edema
