which veins are accesible to examination

Answer 6

femoral, popliteal, great and small saphenous, connecting veins that join two sets, jugular veins

Question 7

venous flow low pressure system

Answer 7

mechanism to keep blood moving by contracting skeletal muscles, pressure gradient caused by breathing and intraluminal valves, in the legs it is the calf pump or peripheral heart

Question 8

what is varicose vein affect on veins

Answer 8

creates incompetent valves leading to increased venous pressure, further dilating the valve

Question 9

functions of lymphatic system

Answer 9

conserve fluid and plasma proteins that leak out of capillaries, form major part of immune system that defends the body against disease, absorb lipids from intestinal tract

Question 10

what are lymph nodes

Answer 10

small oval clumps of lymphatic tissue located at intervals along vessels

Question 11

spleen

Answer 11

destroys old RBCs and stores RBCs, produces antibodies, filters microorganisms from the blood

Question 12

tonsils

Answer 12

located at entrance to respiratory and digestive tracts and respond to local inflammation

Question 13

thymus

Answer 13

behind sternum and in front of aorta

Question 14

vascular vs. lymphatic

Answer 14

vascular moves blood, lymphatic moves plasma proteins from the tissues to the blood

Question 15

inguinal lymph nodes

Answer 15

can be palpated, should be small, less than 1 cm, moveable and non-tender
SHOULD NOT BE: enlarged, tender, fixed

Question 16

epitrochlear lymph nodes

Answer 16

not palpable, SHOULD NOT BE: enlarged, palpable

Question 17

inspection of the arms

Answer 17

• note color of skin and nail beds, temperature, texture, turgor, presence of lesions or clubbing
• check cap refill
• check radial pulses

Question 18

inspection of the legs

Answer 18

• measure leg at widest point
• in the presence of ulcers, gangrene, discoloration, note size and exact lcoatino
• palpate lower extremity pulses using bilateral comparison
• palpate for temperature
• use monofilament to asses neurovascular status

Question 19

what arteries should you palpate in the leg

femoral, popliteal, dorsalis pedis, posterior tibial

Question 20

assess pretibial edema

Answer 20

firmly deprss skin over tibia, grade 0-4

Question 21

1+ scale of edema

Answer 21

mild, slight indentatino, no perceptible sweating

Question 22

2+ scale of edema

Answer 22

moderate pitting, indentation subsides rapidly

Question 23

3+ scale of edema

Answer 23

deep pitting, indentation remains, leg looks swollen

Question 24

4+ scale of edema

Answer 24

very deep pitting, indentation lasts a long time, leg grossly swollen and distorted

Question 25

what should you do if you suspect arterial deficit?

Answer 25

have the patient raise legs about 12 inches off table and have them wag their feet for 30 seconds to drain venous blood, color will now only reflect contribution of arterial blood, color should return in 10 seconds or less
