32
Q

Objective Data: Suspected Arterial Deficit

A
  1. raise legs 12 in. off the table and ask person to wag their feet for 30 sec. to drain venous blood (skin color now reflects arterial blood)
  2. have patient sit up with legs over side of table, compare color bilaterally and note time for color to return to feet (10 sec. or less)
  3. note time it takes for superficial veins around feet to fill (15 sec.)
33
Q

What is the Doppler ultrasonic probe used to detect?

A

weak peripheral pulses
monitor BP in infants and children
measure a low BP or BP in a lower extremity

MAGNIFIES PULSATILE SOUNDS

34
Q

How do you use the Doppler Ultrasonic Probe?

A
  1. apply gel to transducer
  2. place transducer over a pulse site
  3. apply very light pressure and tilt probe around till you locate swishing, whooshing sound of the pulse
35
Q

What does the ankle-brachial index determine?

A

the extent of PAD (peripheral artery disease)

36
Q

How do you prepare a patient for the ankle-brachial index?

A
  1. Patient lying flat for 5-10 mins.
  2. No smoking 2 hours before
  3. Choose correct cuff size for measurements
  4. Position the ankle cuff just above malleoli
37
Q

What are the steps for the ankle-brachial index?

A
  1. Locate pulse with Doppler
  2. Inflate the cuff 20 mmHg above disappearance of flow signal
  3. Deflate slowly to detect reappearance of flow signal
  4. Measure right arm, right posterior tibial (PT), right dorsalis pedis (DP), left PT, left DP, left arm
  5. calculate ABI using formula
38
Q

What is the Wells score for?

A

probability of DVT (low, moderate, or high)

39
Q

Developmental Competence: Infants and Children

A

transient acrocyanosis and skin mottling at birth
pulse forces should be normal and symmetrical
palpable lymph nodes common

40
Q

Developmental Competence: Pregnancy

A

expect diffuse bilateral pitting edema in lower extremities
varicose veins common in 3rd trimester
remain alert for generalized edema plus hypertension (preeclampsia)

41
Q

Developmental Competence: Aging Adult

A

DP and PT pulses may be harder to find
trophic changes associated with arterial insufficiency (thin, shiny skin, thick ridged nails, loss of leg hair) occur normally

42
Q

What are some examples of effective health promotion?

A

CHECK FEET OFTEN (look for skin changes, wash frequently, keep toenails trimmed)
KEEP BLOOD FLOWING (walk or rotate ankles, keep legs uncrossed while sitting)
WEAR SHOES THAT FIT
KEEP SKIN SOFT AND SMOOTH (avoid oils and bubble bath too slippery!)

  7. cold feet
54
Q

What are superficial varicose veins?

A

dilated leg veins from chronic increased venous pressure (obesity, multiple pregnancies, prolonged standing)

MORE COMMON IN WOMEN

new varicosities sit on surface of muscle or bone; older ones are deep and feel spongy

55
Q

What is deep vein thrombophlebitis (DVT)?

A

vein occluded by a thrombus, causing inflammation, blocked venous return, cyanosis and edema

sudden onset of sharp, intense and deep muscle pain, requires emergency referral due to pulmonary embolism risk

WELLS CRITERIA

56
Q

What are occlusions?

A

calcification of the vessel wall and thrombus formation caused by atherosclerosis

RISK FACTORS: obesity, smoking, hypertension, diabetes mellitus, elevated serum cholesterol, sedentary lifestyle, family history of hyperlipidemia

57
Q

What are aneurysms?

A

sac formed by dilation in the artery wall which causes wall to weaken and pressure creates a balloon

MOST COMMON SITE IS AORTA, CAUSED BY ATHEROSCLEROSIS IN MEN

58
Q

8 STEP SUMMARY CHECKLIST FOR PERIPHERAL VASCULAR EXAMINATION

A
  1. Inspect arms for color, size, lesions
  2. Palpate pulses: radial, brachial
  3. Check epitrochlear node
  4. Inspect legs for color, size, lesions, trophic skin changes
  5. Palpate temp of feet and legs
  6. Palpate inguinal nodes
  7. Palpate pulses: femoral, popliteal, posterior tibial, dorsalis pedis
