Q

What is the Allen’s Test?

A

This is a test that MUST be done prior to RADIAL ARTERY CATHETERIZATION

  • Occlude radial & ulnar arteries
  • Release one artery & visualize blood flow to the hand

Q

What is Trendelenburg Test?

A

1) With patient supine, flex leg at hip & elevate leg to empty veins
2) Place superficial tourniquet around thigh to occlude superficial veins
3) Stand patient up

  • **Normal= filling from below within 3-5 seconds
  • **Abnormal= filling from below due to incompetent valves in DEEP COMMUNICTING VEINS

4) If after 20 seconds no filling, remove tourniquet

*****Sudden filling= incompetent SUPERFICIAL VEINS

25
What is lymphadedema?
Edematous swelling due to excess accumulation of lymph fluid in tissues
26
Describe the results of a normal lymph node examination.
Non-palpable nodes or very small nodes
27
Describe the results of an abnormal lymph node examination.
Palpable, shotty (like buck-shot), or tender lymph nodes
28
Where is the occipital node?
Base of the skull
29
Where is the posterior auricular node?
Over the mastoid process
30
Where is the periauricular node?
In front of the ear
31
Where is the tonsillar node?
At the angle of the mandible
32
Where is the submandibular node?
Inferior jaw-line; halfway between the angle of the mandible & chin
33
Where is the submental node?
Inferior jaw-line; behind the chin
34
Where is the anterior cervical node?
In front of the SCM
35
Where is the posterior cervical node?
Two chains: 1) Anterior border of the trapezius 2) Deep to the SCM
36
Where is the supraclavicular node?
At the angle formed by the clavicle & SCM *****Also called Virchow's node
37
Where are the axillary nodes?
In the axilla
38
Where is the epitrochlear node?
Proximal & posterior to the medial condyle of the humerus
39
Where is the superior superficial inguinal node?
Superficial in the inguinal canal
40
Where is the inferior superficial inguinal node?
Deeper in the groin that the superficial inguinal node
41

Posterior fossa of the knee
42
How do you palpate the axillary lymph nodes?
1) Patient seated, ABduct the arm 30-45 degrees 2) Right arm in right hand, use alt. hand to palpate five surfaces - Apex - Medial along rib cage - Lateral--upper surface of medial humerus - Anterior--pectoralis m. - Posterior--lat. dorsi m.
43
How do you palpate the epitrochlear node?
1) Patient seated, flex arm to 90 degrees 2) W/ non-dominant arm, supine wrist & hold 3) Locate biceps/ triceps groove 4) Palpate
44
What should your thought process be if a lymph node is hard & discrete?
Malignancy
45
What should your thought process be if a lymph node is rapidly enlarging WITHOUT inflammation?
Malignancy
46
What should your thought process be if a lymph node is slowly enlarging over weeks or months?
Benign
47
What should your thought process be if a lymph node is tender?
Inflammation
48
What should your thought process be if a lymph node is pulsatile?
Not a lymph node--artery
49
What should your thought process be if there is enlargement to the left supraclavicular node or "Virchow's node"?
Thoracic or abdominal malignancy
50
How should you assess for LE edema?
Press thumb firmly over the area for at least 5 seconds
51
How is edema graded?
``` 1+ = slight distortion, disappears rapidly 2+ = slight pit, disappears within 10-15 seconds 3+ = Pit that lasts more than a minute 4+ = Deep pit that lasts >2-5 min. ```

Congenital malformation of dilated lymphatics
58
What does matted mean?
Noes that feel connected & appear to move as a single unit
59
What are the causes of a false positive with doppler?
1) Cold temperature 2) Too much pressure 3) Congenitally absent or "misplaced" DP
60
