Question Answer
do arteries have valvesno
purpose of valvesPrevent blood back flow
type of veins that are responsible for ulcersPerforator
type of veins with one-way valvesdeep, superficial, and perforating veins
purpose of veinssent deoxygenated blood back to heart
purpose of lymph systemdrain the body of junk
where do lymph juice go?spleen, produce antibiotic , destroying RBC and storing RBC
What does the thymus docontributes to the development and maintenence of the immune system
What happens to the thymus after pubertyIt shrinks in size and a lot of it gets replace by adipocytes
Where is the thymus locatedlower part of the neck-- anterior part of the superior mediastinum
Intermittent claudication seen which PVD or PAD?PAD
Fingers that change color with the coldArterial spasms
Do call patient with PAD have symptoms?no only 10%, need to be screened
ABI?Arterial Bracheal Index
amplitudewhat is felt when taking pulse
Allen test how performedto perform or evaluate circulation in the hands, both in the radial and the ulnar arteries. The patient is asked to make a fist. The nurse compresses both the ulnar and radial artery to blanch the hand. The patient is asked to open the hand as the nurse releases pressure on one or the other of the arteries. Color returning to the hand confirm perfusion
Purpose of Allen testcheck for collateral perfusion
Gangrene seen in which PAD or PAD?PAD
(assessment) femoral pulsepress below inguinal ligament next to symphysis pubis
(assessment) popliteal pulseflex knee, midline behind knee
(assessment) dorsalis pulsedorsum of foot
(assessment) posterior tibial pulse behind and below medial malleolus of ankle
How to assess retrograde fillingTrendelenburg test
Why hold breath during neck vessle auscultation?so clinician can hear for bruits
What are the parts auscultated on neck vessle (3)?angle of jaw, mid cerical region, base of neck


Question Answer
Cap. refill peripheral artery diseaseCap refill in PAD is GREATER than 3 second,
Cap. refill venous diseaseit doesn't affect cap refill in venous disease, so less than 3, unless there is edema
Peripheral pulses in PAD vs. venous disease?Decreased or absent in PAD, but present in venous disease, although may be difficult to palpate r/t EDEMA
Edema in PAD vs. venous disease?Typically absent in PAD but lower leg edema in venous disease due to back-up of fluid
Hair differences in PAD vs. venous diseaseLoss of hair on legs, feet and toes in PAD vs. no difference
Ulcer location in PAD Ulcers would be in tips of toes, foot, or lateral malleolus
Ulcer location in PVDNEAR MEDIAL MALLEOLUS in venous disease (think ankle area)
Ulcer margin in PADRounded, smooth, looks "pouched out"
Ulcer margin in venous disease? irregularly shaped in venous disease
Drainage from ulcers in PADMinimal drainage in PAD but lots in venous disease
Drainage from ulcers venous disease?yes
Shinny, streched skinPAD
Ulcers at the tip of the toesPAD
Absent pulsePAD
Cool tempPAD
Normal TempPvD
Ulcer at point of tramaPAD
Tissue of ulcers in PAD vs. venous disease?Black eschar or pale pink granulation vs. yellow slough or dark red, "ruddy" granulation
Pain in PAD vs. venous diseaseIntermittent claudication or rest pain in foot, ulcer may not be painful vs. dull ache or heaviness in calf or thigh, ulcer often painful
Nails in PAD vs. venous diseaseThickened and brittle in PAD vs. normal or thickened
Skin color in PAD vs. venous diseaseDependent rubor; elevation pallor vs. bronze-brown pigmentation, varicose veins
Skin texture in PAD vs. venous diseaseThin, shiny, taut vs. thick, hardened
Skin temp in PAD vs. venous diseaseCool, temperature gradient down leg vs. warm and no temperature gradient
Dermatitis and pruritis in PAD vs. venous diseaseBoth rarely occur vs. often occurring
