Q

Upper Extrem Pulse Obtainability

A
  • Arterial pulses are palpable when artery lies close to body surface
  • In upper extremity the ulnar pulse may be obscured by overlying tissues

Q

Veins

(two relative locations, descriptions)

A
  1. Deep veins - carry 99% of venous return from lower body, well supported by surrounding tissues
  2. Superficial veins - subcutaneous and poorly supported by surrounding tissues

Q

Blood Movement in Veins

A
  • All veins (deep, communicating, superficial) have one way valves
  • Blood flows from superficial → deep toward the heart
  • Muscle pumps sqeeze blood against gravity
  • Competent valves prevent backflow

Q

Pulse Technique

(4 aspects)

A
  1. Use fingertips, not thumbs
  2. Firm even pressure
  3. Ensure you are perceiving the pt’s pulses, not your own
  4. Never palpate both carotids at once

Pulse Descriptions

(5)

A

*Remember to compare these bilaterally and note assymetry *

  • 0: absent unable to palpate
  • +1: diminished, weaker than expected
  • +2: brisk, expcted (avg)
  • +3: increased
  • +4: bounding

Q

Arterial Occlusion

(definition, clinical presentation, pt pop)

Presentation - decreased/absent pulses distal to occlusion (usually in thigh)

Pt Pop: diabetics

Q

Symptoms of Ischemia (c arterial occlusion)

(6)

A

6 P’s

  1. Polar (cold) - typically first notable symptom
  2. Pain - 80% of cases; absent in remaining 20% due to prompt onset of anesthesia or paralysis
  3. Pallor - replaced by mottled cyanosis in a few hours
  4. Paresthesia - loss of light touch followed by other sensory modalities
  5. Paralysis/Power - indicative of severity
  6. Pulselessness

Q

Carotid Pulse Procedure

(3 steps)

A
  1. Inspect neck for pulsations just medial to SCM
  2. Place 2nd and 3rd fingers on lower 1/3 of neck
  3. Press posteriously and feel for pulse

Q

Brachial Pulse Procedure

(4 steps)

A
  1. Patient’s arm should rest c elbow etended palm up
  2. Use 2nd and 3rd digits of opposite hand
  3. Cup hand under pt’s elbows
  4. Feel for pulse just medial to biceps tendon
17
Q

Radial Pulse Procedure

(2 steps)

A
  1. Use pads of fingers on the flexor surface of the lateral wrist
  2. Partially flexing pt’s wrist may help
18
Q

Ulnar Pulse Procedure

A

Using the pads of your fingers, feel for the pulse deeply on the flexor surface of teh wrist medially

19
Q

Femoral Pulse Procedure

A

Press deeply below the inguinal ligament and about midway between teh anterior superior iliac spine and the symphysis pubis

20
Q

Popliteal Pulse Procedure

(4 steps)

A
  1. Patient should be prone
  2. Flex the knee to 90 degrees
  3. Let the leg rest against you
  4. Use your thumbs to press deeply into the popliteal fossa
21
Q

Dorsalis Pedis Pulse Procedure

(2 steps)

A
  1. Feel the dorsum of the food just lateral to the extensor tendon of the great toe
  2. If no luck, try more laterally
22
Q

Posterior Tibial Pulse

A

Curve your fingers behind and slightly below the medial malleolus of the ankle

23
Q

Examination Technique for Edema

A
  1. Press firmly but gently for 5 seconds over
    • ​Dorsum of each foot
    • Behind medial malleolus of each ankle
    • Over each shin
  2. Observe for pitting (depression caused by finger pressure)
    • ​Bilateral edema is usually pitting
    • Unilateral may not be
  3. Grade edema on 5 point scale (trace to +4)
  4. In the event of present edema, measure and compare circumference bilaterally in the following places. Difference of > 1 cm above ankle or 2 cm above calf is unusual and can suggest edema.
    • ​Forefoot
    • Above ankle
    • Largest circumference of calf
    • Mid-thigh (measured distance above the patella c knee extended)
24
Q

Edema Scoring

A
  • Trace = minimal edema of foot
  • +1 = edema of foot
  • +2 = edema to ankle
  • +3 = edema halfway up shin
  • +4 = edema to knees
25
Q

Edema Causes

(4)

A
  1. Recent DVT
  2. Chronic venous insufficiency
  3. Incompetent venous valves
  4. Lymphedema
26
Q

Varicosity Examination

(3 steps)

A

You can map the course of varicosities by transmitting pressure waves in filled veins

  1. Stand pt
  2. Place fingers gently on vein
  3. Compress sharply
27
Q

Lower Extremity Fluid Pathology

(3)

A
  • Superficial thrombophlebitis - local swelling, reddness, warmth, and palpable cord
  • Venous insufficiency - brownish color or ulcers just above the ankle
  • Lymphedema - thickened skin
28
Q

Allen Test

(purpose, indication, procedure)

A

Purpose: Evaluate arterial blood supply to the hand

Indication: Assess ulnar artery patency before puncturing radial artery for blood draws or line placement

Procedure:

  1. Position pt’s hands c palms up
  2. Occlude radial and ulnar arteries
  3. Instruct pt to tighten fist
  4. Instruct pt to release fist
  5. Observe palor of hand
  6. Open one artery
  7. Circulation is intact if hand turns pink
29
Q

Capillary Refill

(Function, Normal, Procedure)

A

Function: assess ability of capillaries to refill c blood when emptied

Normal: < 3 sec

Procedure:

  1. Ensure clean nails - no polish, blood, or fungus
  2. Press on end of nail until nail bed becomes pale
  3. Release and assess time to turn pink
