Peripheral Vascular System
| Question | Answer |
|---|---|
| What do arteries do? | carry oxygenated, nutrient rich blood from the heart to the capillaries. |
| How is blood propelled? | under pressure from the left ventricle of the heart |
| Arterial Pulse is? | the surge of blood that is forced through the arterial vessels under high pressure. |
| peripheral arteries | the major arteries of the arms and legs that are accessible to examination |
| brachial artery | the major artery that supplies that arm |
| Where can the brachial artery be palpated? | medial to the biceps tendon in and above the bend of the elbow |
| radial artery | a division of the brachial artery; divides near the elbow it extends down the thumb side of the arm |
| Ulnar artery | a division of the brachial artery; divides near the elbow and extends down the little finger side of the arm |
| Where can the radial pulse be palpated? | on the lateral aspect of the wrist |
| Where is the ulnar pulse located? | on the medial aspect of the wrist, it is deeper pulse and may not be easily palpated |
| What are veins? | blood vessels that carry deoxygenated blood, nutrient depleted, waste-laden blood from the tissues back to the heart. |
| where do the veins of the arms, upper trunk, head and neck carry blood to? | superior vena cava |
| where does blood of the legs and lower trunk drain into? | inferior vena cava |
| The veins contain what percentage of the body's blood volume? | nearly 70% |
| the three types of veins are? | deep, superficial, and perforator |
| The venous system is a _________ ___________ system? | Low pressure |
| what function do the lymph nodes serve? | they trap and destroy microorganisms, foreign material, dead blood cells, and abnormal cells |
| Where does the right lymphatic duct drain into? | the upper right side of the body, then back into the subclavian veins |
| Thoracic duct | drains the remaining lymph that does not go to the right lymphatic duct and returns it to subclavian veins |
| What is DVT | Deep vein thrombosis; a blood clot in a deep leg vein; can develop in the lower leg or thigh |
| Where DVT is more serious in the leg or thigh | The thigh because the clot can travel to the lungs |
| Risk factors of DVT | some cancers and cancer treatments sitting for long periods, esp the car or airplane Pregnancy esp the first 6 weeks and after giving birth 60 years of age or older Birth control pills overweight |
| The use of oral or transdemal patches amount female clients increases the risk for? | thrombophlebitis, Raynaud's disease, hypertension, and edema |
| The use of support hose to treat varicose veins may? | help reduce venous pooling and increase blood reaturen to the heart |
| When compression the nail bed to assess capillary refill what is consider a normal finding? | The capillary beds refill in 2 seconds or less |
| An abnormal capillary bed refill time may indicate? | vasoconstriction; decreased cardiac output, shock, arterial occlusion, or hypothermia |
| When assessing the PV system what factors can contribute to inaccurate findings? | If the room is cool, the client has edema, anemia, or the client has recently smoked a cigarette |
| When palpating the radial pulse what should you note? | elasticity and strength |
| should brachial pulses have equal strength bilaterally? | Yes; normal pulses bilaterally are considered normal assessment findings |
| Enlarged epitrochlear lymphnodes may indicate? | an infection in the hand or forearm, or may occur with generalized lymphadenopathy |
| Can you palpate the epitrochlear lymph nodes? | No |
| Bilaterial edema in the legs usually indicates? | a systemic problem such as congestive heart failure or a local problem such as lympedema |
| when palpating bilaterally for temperature of the feet and legs what side of your fingers should you use? | The backs of your fingers |
| Varicous veins result from? | incompetent valves in the veins, weak vein walls, or an obstruction above the varicosity |
| Are varicosities common in older clients? | Yes |
| A weak or absent posterior tibial pulse indicates? | partial or complete arterial occlusion |
| When do you perform the manual compression test | if the client has varicose veins; this test assess the competence of the vein's valves |
| The Tandenlenburg test is used to determine | the competence of the saphenous vein valves and the retrograde filling of the superficial veins. |
