Q

Can you feel lymph nodes in most people?

A

No; you can in children though

23
Q

What are the 4 “headquarter” lymph nodes?

A

Cervical nodes
Axillary nodes
Epitrochlear nodes
Inguinal nodes

24
Q

What do the cervical nodes drain?

A

Head and neck

25
What do the axillary nodes drain?
Breast and upper arm
26
Where is the epitrochlear node near?
The elbow
27
What does the epitrochlear node drain?
Hand and lower arm
28
What does the inguinal nodes drain?
Lower extremity, external genitalia, and anterior abdominal wall
29
What do you inspect for in the upper extremities?
``` Skin color Temp Texture Skin turgor Nail bed color Clubbing Cap refill ```
30
For the upper extremities, where do you feel the temperature?
Feel temp at the BACK of the hand (the dorsal surface)
31
What do you inspect on the lower extremities?
``` Skin color Temp Hair distribution Venous pattern Size Lesions or ulcers ```
32
For lower extremities, why is important to look for hair distribution pattens?
Hair distribution in the lower extremities means there is bad circulation to the lower extremities
33
What may occur to the lower extremities when blood is able to come down, but it can't drain back out?
Venous or arterial stasis
34
Usually, what is more seen: venous or arterial stasis?
Venous
35
How is venous stasis characterized by?
Brawny edema Skin coarse, thick, and hard Pulse is still normal Skin is brownish color
36
Why is the skin a brownish color in venous stasis?
The RBC are leaked into the tissue and are dying or being lysed and the iron is leaving the RBCs
37
If a patient had arterial stasis, would we still be able to feel their pulse like we can with venous stasis?
No
38
What is raynaud phenomenon and where is this seen?
This is due to arterial spasms and blood cannot get where they need to go. This happens in the upper extremities
39
What are the characteristics of Raynaud Phenomenon?
Colors of red, white, and blue patterns | Cold hands
40
If a patient has Raynaud Phenomenon, what can you tell them to do when they feel an onset of symptoms?
Tell them to swing their arms around like a wheel (a circumferential movement)
41
What is the pulse grading chart?
``` 3+ = full, bounding 2+ = normal 1+ = weak, thready 0 = absent ```
42
How do we find femoral pulses, particularly in obese people?
- Ask the person to bend their knees to the side like a froglike position - Press firmly, then slowly release, noting the pulse tap under your fingertips - If the pulse is weak or diminished, auscultate the site for a bruit
43
What side of the stethoscope do we listen to a bruit with?
The bell (low pitched sound)
44
How do you find the posterior tibial pulse?
Curve fingers around the medial malleous, the pulse is somewhere in between medial malleous and Achilles tendon
45
Where is the dorsalis pedis pulse?
Lateral to tendon of the great toe
46
How many seconds do you press for when checking edema?
5 seconds
47
What is it called when edema is only on one side?
Unilateral edema
48
When does unilateral edema occur?
With occlusion of a deep vein
49
Unilateral or bilateral edema occurs with _______.
Lymphatic obstruction
50
What are the characteristics when it is lymphatic obstruction?
Brawny or non-pitting and feels hard to the touch
51
Are lymph nodes normally palpable?
No
52
When are there enlarged lymph nodes?
Infection Malignancy Immunologic disease
53
Are lymph nodes in infants and children palpable?
Yes
54
How do lymph nodes in children feel?
Small Firm (shotty) Mobile Non-tender
