Q

Those at greater risk should

A

avoid constriction of extremity
diet and exercise to maintain healthy weight
when exercising, observe any changes in limb
avoid extreme hot and cold
wear compressions during strenuous activity and when standing or sitting for long periods of time

20
Q

Procedure for limb circumference measuring

A

7 circumferences recommended for upper and lower extremities to see if fluid has been removed and not just redistributed

21
Q

A difference of ___-___cm between 4 comparative circumferences on bilateral UE is evidence of lymphedema.

A

2-3

22
Q

Mild lymphedema is classified as

A

<3 cm between affected and unaffected limbs

23
Q

Moderate lymphedema is classified as

A

3-5 cm

24
Q

Sever lymphedema is classified as

A

> 5 cm

25
Q

Staging of Lymphedema:
0

A

latent or preclinical stage
no visible edema
transport capacity is affected

26
Q

Staging of Lymphedema:
1

A

reversible
pitting edema present and increases with activity or heat but diminishes with elevation and rest.

27
Q

Staging of Lymphedema:
2

A

spontaneously irreversible
non-pitting edema and does not change with elevation or rest
skin begins to show fibrotic changes
stemmers sign is positive

28
Q

Staging of Lymphedema:
3

A

elephantiasis stage
extensive non-pitting edema
significant fibrotic changes
papillomas
skinfolds
kyperkeratosis
infection is common

29
Q

Treat lymphedema with

A

complete decongestive therapy

30
Q

CDT two phases:

A

Phase I is acute treatment in outpatient 4-6 weeks
Phase II is self-management
Can return to phase I when significant changes are noted.

31
Q

CDT consists of

A

manual lymphatic drainage
compression therapy
exercise
skin care

32
Q

Compression therapy is in phase ___.
___-____bandages are used because they have a ____ resting pressure.
Phase II consists a ___ of compression during the day and night.
Bandages and garment should have ____ pressure distally.

A

I
short stretch
low
combination
higher

33
Q

Basic guidelines for exercise should start with

A

trunk exercises
followed by extremity working from proximal to distal
end with trunk again and deep breathing
wear compression during exercise

34
Q

Soaps and moisturizers in lymphedema

A

low or neutral pH

35
Q

Contraindications to CDT

A

acute infection
cardiac edema
diabetes
HTN
malignancy
renal insufficiency
DVT

36
Q

A

parasitic infection most often seen in tropical climates
most common causes of secondary lymphedema

A

thickening of outermost layer of skin
observed in stage 3 lymphedema

38
Q

Lymphadenitis

A

inflammation and infection of lymph nodes

39
Q

A

enlargement of lymph nodes
secondary to cancer, infection, allergic reactions

40
Q

Lymphadenopathy

A

affects size, number or consistency of lymph nodes

41
Q

Lymphangitis

A

infection and inflammation of lymphatic sys

A

inherited type of primary lymphedema that typically presents in infancy. BLE

43
Q

Papilloma

A

benign wart in stage 3

44
Q

Spleen

A

upper left quadrant
responsible for filtration of RBCs as well as production of antibodies to fight infection

45
Q

Stemmers sign

A

positive if dorsal base of second toe/finger cant be easily lifted away from bone which indicates thickening of skin due to fibrotic changes

46
Q

Thymus

A

posterior to sternum and anterior to heart that produces T cells and T lymphocytes to help combat infection
