Ch 20 Periheral Vascular & Lymphatic System

Question 0

Perforators

Answer 0

Connecting veins that join two sets. They also have one way valves that route blood from the superficial into the deep veins

Question 1

Arteries (pulses)

Answer 1

Temporal Carotid Brachial Radial Femoral Popliteal (behind the knee), Posterior Tibial , and Dorsalis Pedis

Question 2

Lymphatics

Answer 2

Form a completely separate vessel system which retrieves excess fluid from the tissue spaces and returns it to bloodstream

Question 3

Lymph Nodes

Answer 3

Small oval clumps of lymphatic tissue located at intervals along vessels arrange deep and superficial nodes filter out microorganism that could be harmful to the body before it is returned to the blood.

Question 4

Superficial Node Groups

Answer 4

Cervical Nodes : drain the head and neck

Axillary node: drain the Brest bs upper arm

Epitrochlear node: in anticubital fossa drains the hand and lower arms

Inguinal nodes: In groin drains the lower extremity genitalia shed the anterior abdominal wall

Question 5

Arteriosclerosis

Answer 5

Peripheral blood vessels grow more rigid with age This condition raises the systolic blood pressure

Question 6

Atherosclerosis

Answer 6

Deposition of Fatty plaques in the intima of the arteries

Question 7

Peripheral Vascular disease PVD

Answer 7

ineffective peripheral Tissue Perfusion
may be related to reduction or interruption of arterial/venous blood flow, possibly evidenced by changes in skin temperature/color, lack of hair growth, blood pressure/pulse changes in extremity, presence of bruits, and reports of claudication.

Question 8

Claudication

Answer 8

The measured amount of an activity that can be done before pain occurs

The number the of blocks walked to produce pain

Caused by arterial insufficiency

Question 9

Grade the pulse force

Answer 9

3+ increased full bounding
2+ normal
1+ weak
0, absent

Question 10

Modified Allen Test

Answer 10

The Allen’s test is testing for abnormal circulation by occluding the radial and ulnar artery having the pt. make a fist for 30 sec. Then releasing to see how long before blood flow return 7sec is normal

Question 11

Grading Pitting Edema

Answer 11

1+ Mild pitting, slight indentation
2+ Moderate pitting indentation
3+ Deep pitting, indentation
4+ Very deep pitting, indentation

Question 12

Pulses Paradoxus

Answer 12

A condition in which the pulses on either side of the body are of unequal intensity. It is seen sometimes in aortic dissection, or in atherosclerotic obstruction of one of the subclavian arteries.

Beats have weaker Amplitude with respiratory inspiration and stronger amplitude with expiration

Question 13

Lymphedema

Answer 13

The swelling of an extremity caused by an obstructed lymph channel

Question 14

Water-hammer pulse

Answer 14

Is associated with aortic valve regurgitation

Question 15

Thymus

Answer 15

Develops t-lymphocytes in young children for the immune system

Question 16

Severe bilateral lower extremity edema

Answer 16

Is most likely a sign of heart failure
