Mod 4 Flashcards
What is an arterial pulse?
A surge of blood
What are major arteries of the arms and legs called?
Peripheral arteries
What is the major artery that supplies the arm?
Brachial artery
Where does the brachial artery divide and what arteries dose it become?
At the elbow and it becomes the radial and ulnar arteries
Where can you palpate the radial and ulnar arteries and which is harder to find?
Radial- on the lateral aspect of the wrist
Ulnar- on the medial aspect of the wrist
The ulnar artery is header to palpate because it is deeper
What artery is the major supplier of blood to the leg and where can you palpate it?
Femoral artery and it can be palpated just under the inguinal ligament
How dose the femoral artery move down the leg?
It travels down the front of the thigh the crosses to the back of the thigh where it is termed popliteal at the back of the knee where it divides below the knee into the anterior and posterior branches. The anterior descends down to the top of the foot and becomes the dorsalis pedis artery. The posterior side becomes the posterior tibial artery.
What are veins?
Are the blood vessels that carry deoxygenated, nutrients- depleted, waste-laden blood from the tissue back to the heart
How do veins differ from arteries?
There is no force that propels forward the blood flow in the veins
What are arteries?
Blood vessels that carry oxygenated blood, nutrient rich blood from the capillaries
70% of the bodies blood volume is contained where?
Veins
How many types of veins are there and what are they?
There are three types of veins:
Deep veins
Superficial veins
Perforator veins
What are the two deep vein located in the leg?
Femoral vein in the upper thigh and the popliteal vein located behind the knee
What are the longest of all the veins?
Saphenous vein
What three mechanism propel blood through the veins?
One way valves permit blood to pass through them on the way to the heart and prevent blood from returning through the opposite direction
Skeletal muscle contract with movement and squeeze the blood toward the heart
Creation of pressure gradient through the act of breathing
What are capillaries?
Are small blood vessels that form the connection between the arterioles and venules they allow the circulatory system to maintain the equilibrium between the vascular and interstitial spaces
What is the primary function of the lymphatic system?
It is to drain excess fluid and plasma proteins from bodily tissue and return them to the venous system
What is the second function of the lymphatic system?
Defending the body against microorganisms
What is the third function of the lymphatic system?
To absorb lipids from the small intestine into the bloodstream
Why is it important to ask a client if they notice any color, temperature, or texture changes in their skin?
Because cold, pale, clammy skin on the extremities and thin, shiny skin with loss of hair are associated with arterial insufficiency and warm skin with a brown pigmentation around the ankles is associated with venous insufficiency
What increases the risk of varicosities?
Pregnancy and standing for long periods of time
What type of ulcers are painless and are located on the lower legs or medial ankle?
Venous ulcer
What are painful ulcer that are often located on the toes, foot, or lateral ankle associated with?
Arterial disease
Obstruction of the lymphatic flow causes what?
Peripheral edema
What are some risk for deep vein thrombosis?
Reduced mobility, dehydration, increased viscosity in the blood and venous stasis
What can increase a woman risk of thrombophlebitis, Raynaud’s disease, hypertension and edema?
Oral or transdermal contraceptives
What are the drug that inhibit platelet aggregation?
Cilostazol/ clopidogrel- to increase blood flow
Aspirin- prolongs blood clotting
Pentoxifylline- reduces blood viscosity
What equipment will you need during a peripheral vascular assessment?
Centimeter tape Stethoscope Droppler ultrasound device Conductivity gel Tourniquet Gauze or tissue Water proof pen Blood pressure cuff
What should you look for if a client tells you that she had a breast surgery?
Lymphedema
What is Raynaud’s disorder?
It is a vascular disorder caused by vasoconstriction or vasospasm of the fingers or toes characterized by rapid changes of color, swelling, pain, numbness,tingling, burning , throbbing and coldness and it last minutes to hours
If capillary refill exceeds 2 seconds it may indicate what?
Vasoconstriction, decreased cardiac output, shock, arterial occlusion or hypothermia
What do increased radial pulses indicate?
Hyperkinetic state
What could decreased pluses be do to?
Buerger’s disease or scleroderma
Last of resilience or Inelasticity of the artery may indicate what?
Arteriosclerosis
If you suspect arterial insufficiency you can do what?
Palpate the brachial pulses
Editor glean lymph nodes are not what?
Palpable
Bilateral edema indicates what?
Systematic problem such as congestive heart failure or local problem such as lymphedema
Prolonged standing or sitting may aide what kind of edema?
Orthostatic edema
What are the associated systemic problems with pitting edema?
Congestive heart failure
Hepatic cirrhosis
Orthostatic edema
When palpating the legs what do you need to compare?
The temperature bilaterally
Coolness may indicate arterial insufficiency
Increased warmth mat indicate a superficial thrombophlebitis
When palpating lymph nodes what would be considered normal finding?
Nontender, movable lymph nodes up to 1 or even 2 cm are commonly palpated
What is a normal findings when auscultating the femoral pulses?
No sounds
Bruins over one or both femoral arteries suggest partial obstruction of the vessel
Why would you ask for a client to stand while inspecting varicose veins?
Because they may not be visible while sitting or in the supine
What are the stages of lymphedema?
Stage 0- no obvious signs or symptoms
Stage I- swelling is present
Stage II - skin tissue is firmer and may appear tight,shiny and feel spongy
Stage III - has progressed to lymphostatic elephantiasis (irreversible)
What a the pulse amplitudes?
0- absent
1+ weak, diminished
2+ normal
3+ bounding
What are characteristics of aterial and venous insufficiency?
Pain: intermittent claudication to sharp, unrelenting constant
Pulse: diminished or absent
Skin characteristics: dependent rubor Elevation pallor of foot Dry shiny skin Cool- to- cold temperatures Loss of hair over toes and dor sum of the foot Nails thickened and ridged
Ulcer characteristics:
Location: tips of the toes, toe webs, heel or pressure areas if confined to bed
Pain: very painful
Depth of ulcer: deep often to joint space
Shape: circular
Ulcer base: pale black to dry and gangrene
What are characteristics of venous insufficiency?
Pain: aching cramping
Pulses: present but may be difficult to palpate through edema

Caused by abnormal or blocked lymph vessels
Nonpitting
Usually bilateral; may be unilateral
No skin ulceration or pigment
What are characteristics of edema associated with chronic venous insufficiency?
Caused by obstruction or insufficiency of deep veins
Pitting documented as:
1+ slight pitting

Usually unilateral; may be bilateral
Skin ulceration and pigmentation may be present
What are the four chambers of the heart?
Left and right atria
Left and right ventricles
Where is the heart located?
In the middle of the thoracic cavity between the lungs in a space called the mediastinum
The anterior chest area that overlies the heart is called what?
Percordium
Which side of the heart pumps blood to the lungs for gas exchange?
Right side
Which side of the heart pumps blood to all the other parts of the body?
Left side
What part returns blood to the right atrium from the upper and lower torso?
Superior and inferior venal cava
What part carries blood to the lungs?
Pulmonary artery
What returns oxygenated blood to the left atrium?
Pulmonary veins
What transports oxygenated blood from the left ventricle to the body?
Aorta
What separate the lady and right side of the heart?
Septum
Why is the left ventricle thicker then the right?
Because it has a greater workload pumping blood out of the heart
What are the propose of the chordate tendineae
To anchor the AV flaps to the papillary muscles within the ventricles
What do the AV prevent?
Regurgitation of blood into the atria
What are the two phases of the cardiac cycle?
Diastole-relaxation of the ventricles, know as filling
systole- contraction of the ventricles, known as emptying
