Q

Functions of the spleen

A

-destroy old RBC
-produce antibodies
-store RBC
-filter microorganisms from the blood

17
Q

Thymus gland

A

Flat, pink gray located in superior mediastinum behind sternum and in front of aorta

-producing T lymphocytes in children

18
Q

Growth pattern of the lymph system across developmental ages

A

Birth- well developed
Child- grows rapidly, reaching adult size
Adolescent- surpasses adult size
Adult- slowly atrophies

19
Q

Lymph nodes in children

A

Relatively large, and superficial are usually palpable without an infection

20
Q

Pregnant women experience vasodilation which causes

A

Drop in blood pressure in first/second trimester

21
Q

A growing uterus will obstruct which veins

A

Obstructs drainage of iliac and inferior vena cava veins

22
Q

What is caused from obstruction of certain veins needed for drainage and a drop in blood pressure?

A

-lowers blood flow
-increases venous pressure
-can cause dependent edema
-varicosities in legs and vulva
-hemorrhoids

23
Q

Peripheral blood vessels grow more rigid with age, resulting in

A

Arteriosclerosis

24
Q

Arteriosclerosis causes

A

A rise in systolic blood pressure

25
What is the deposition of fatty plagues on the intima of the arteries
Atherosclerosis
26
Both arteriosclerosis and atherosclerosis are present in which condition?
PAD
27
PAD
Atherosclerotic occlusive disease of lower extremities, and a major risk factor for lower extremity amputation
28
Aging produces a progressive
Enlargement of intramuscular calf veins
29
Prolonged bed rest, prolonged immobilization and heart failure all increase the risk of
Deep vein thrombosis and subsequent pulmonary embolism
30
What does clubbing insinuate
This occurs with congenital cyanotic heart disease and cor pulmonale (enlargement and failure of right ventricle)
31
Force grade system for radial pulses
3- increased, full bounding 2- normal 1- weak 0- absent
32
Malnutrition signs in skin
Thin, shiny, atrophic -nails have thick ridges -malnutrition, pallor and coolness
33
When does brown discolouration occur
Chronic venous stasis as a result of hemosiderin deposits form red blood cells
34
Venous ulcers occur usually at the ____ and why?
Medial malleolus -due to bacterial invasion of poorly drained tissues
35
Arterial deficit may cause
One food or leg to be more cool/temperature may drop suddenly
36
When does a bruit occur
Turbulent blood flow indicating partial occlusion
37
Modified Allen test
Evaluates adequacy of collateral circulation before radial artery is cannulated
