Q

what are the functions of the lymphatic system?

A
  • Conserve fluids and plasma proteins that leak out of the
    capillaries
  • Form a part of the immune system
  • Absorb lipids from the intestinal tract
19
Q

converge and drain into 2 main trunks

A

lymph vessels

20
Q

what are the 2 main trunks of the lymph vessels?

A

right lymphatic duct
thoracic duct

21
Q

drains the right side of the head and neck, right arm, right side of the thorax, right lung and pleura, right side of the heart, upper right section of the liver

A

right lymphatic duct

22
Q

drains the rest of the body

A

thoracic duct

23
Q

what are lymph nodes?

A
  • Small oval clumps of lymphatic tissue
  • Located in intervals along the vessels
  • Mostly arranged in groups in the body
  • Superficial and deep
24
Q

what are lymph nodes able to do?

A

filter the fluid before it returns to the bloodstream; filter out
microorganisms that could be harmful to the body

25
Q

what are the superficial nodes that are accessible for inspection and palpation?

A

cervical
axillary
epitrochlear
inguinal

26
Q

drain head and neck

A

cervical node

27
Q

drain the breast and upper arm

A

axillary node

28
Q

drain the hand and lower arm

A

epitrochlear node

29
Q

drain most of the lymph of the lower
extremity, the external genitalia, and the anterior
abdominal wall

A

inguinal node

30
Q

what are the cultural and developmental considerations during pregnancy?

A
  • Hormonal changes cause vasodilation – blood pressure
    drops in first and second trimesters
  • Venous pressure increases because the growing uterus
    obstructs drainage of the iliac veins and inferior vena
    cava
  • Can causes dependent edema, varicosities in the legs
    and vulva, and hemorrhoids
31
Q

what are the cultural and developmental considerations of older adults?

A
  • Peripheral blood vessels get more rigid with age – this
    results in arteriosclerosis (causes rise in systolic blood
    pressure)
  • Intramuscular calf veins enlarge
  • Fewer number of lymph nodes and lymph nodes size
    decreases
  • Dorsalis pedis and posterior tibial pulses may become
    more difficult to find
  • Trophic changes associated with arterial insufficiency
    also occur normally with aging
32
Q

how do we prep for examination of peripheral vascular and lymphatic system?

A
  • Examination includes: peripheral vascular characteristics, skin (ch.13),
    musculoskeletal findings (ch.24), and neurological findings (ch.25)
  • Room temperature should be warm, but not hot (avoid vasoconstriction
    and vasodilation)
  • Compare findings bilaterally
33
Q

what is the equipment we need?

A
  • Stethoscope
  • Paper tape measure
  • Tourniquet or blood pressure cuff
  • Doppler
34
Q

how do we inspect the hands?

A
  • Note: Colour of the skin and nail beds, temperature,
    texture, and turgor of the skin
  • Note: Presence of lesions, edema, clubbing (profile sign)
  • Check capillary refill
35
Q

how do we inspect the arm?

A

Note: whether the arms are symmetrical in size (normal
finding)
* Asymmetry can occur with edema from obstructed lymphatic
drainage (i.e. after breast surgery)
* Note: presence of scars

36
Q

what pulses do we palpate?

A

radial and brachial

37
Q

how do we inspect and palpate the epitrochlear lymph node?

A
  • Location: depression above and behind the medial condyle of
    the humerus
  • Assessment:
  • “shake hands” with the client
  • Reach the other hand under the client’s elbow to the groove between
    the biceps and triceps muscles, above the medial epicondyle
38
Q

what are the normal and abnormal findings of epitrochlear lymph node?

A
  • Normal: node is not palpable
  • Abnormal: enlarged (infection in hand or arm; conditions of
    generalized lymphadenopathy)
39
Q

how do we inspect the legs?

A
  • skin colour, hair distribution, venous pattern, skin lesions,
    ulcers
  • skin discolouration, skin ulcers, gangrene
  • size (swelling and atrophy) and symmetry in size
40
Q

what are the abnormal findings of the legs?

A
  • Diffuse bilateral edema – systemic illnesses
  • Acute unilateral, painful swelling and asymmetry of calves 1 cm
    or more (refer client to determine is DVT is present)
  • Asymmetry - lymphedema (mild, moderate, severe)
  • Mild (1-3 cm), moderate (3-5 cm), severe (>5 cm)
  • If asymmetry noted or if DVT suspected, measure the calf
    circumference with a non-stretchable tape measure
  • Measure at the widest point at the exact same place for both legs
    (measure the number of cm down from the patellar)
  • If lymphedema is suspected, measure at the ankle, distal calf, knee, and
    thigh
41
Q

how do we palpate the legs?

A
  • Palpate for temperature
  • Palpate the inguinal lymph nodes
  • It is not unusual to palpate small nodes (1 cm or less) that are moveable
    and non-tender
  • Abnormal: nodes that are enlarged, tender, or fixed
  • Pulses:
  • Palpate the pulses in both legs
  • Grade the pulses on the four point scale
  • Femoral, popliteal (more diffuse pulse, can be difficult to localize – can
    use 2 approaches), posterior tibial, dorsalis pedis
42
Q

how do we assess the venous system?

A
  • Ask client to stand and note any visible, dilated, and tortuous veins
  • Assess for arterial deficit (colour change test):
  • Raise client legs approx. 30 cm off the table and ask client to wag
    the feet for approximately 30 seconds
  • Then, ask the client to sit up with the legs over the side of the
    examination table
  • Compare the colour of both feet – note the time it takes for the
    colour to return (normal: 10 seconds or less), note when the
    superficial veins fill (normally about 15 seconds)
  • Test the lower legs for strength (ch.24)
  • Test the lower leg for sensation (ch.25)
43
Q

what is the doppler ultrasonic stethoscope used for?

A
  • Detect a weak peripheral pulse
  • Monitor blood pressure in infants and children
  • Measure a low blood pressure
  • Measure blood pressure in a lower extremity
44
Q

what is the procedure for using the ultrasonic stethoscope?

A
  • Position the client
  • Place coupling gel on the end of the transducer
  • Place the transducer over the pulse site at a 45 degree angle
  • Apply very light pressure
  • The pulse is located when the swishing, whooshing sound is
    heard
