Question 14

Ankle Brachial Index (ABI) Normal

Answer 14

• 1.0-1.30 = normal; no blockage

Question 15

ABI mild blockage

Answer 15

• 0.8-0.99 = Mild blockage; beginnings of peripheral artery disease

Question 16

ABI Moderate blockage

Answer 16

• 0.4-.79 = Moderate blockage; may be associated with intermittent claudication during exercise
  est

Question 17

ABI Severe blockage

Answer 17

• <0.4 = Severe blockage suggesting severe peripheral artery disease; may have claudication pain at rest

Question 18

ABI indicating rigid arteries

Answer 18

-Greater than or equal to 1.30 = rigid arteries and the need for US test to check for peripheral artery disease

Question 19

Angina pain scale 1

Answer 19

Mild, barely noticable

Question 20

Angina pain scale 2

Answer 20

Moderate, bothersome

Question 21

Angina pain scale 3

Answer 21

Moderately severe, very uncomfortable

Question 22

Angina pain scale 4

Answer 22

Most severe or intense pain ever experienced

Question 23

ABI procedure

Answer 23

• Compares Systolic BP of ankle and arm to check for peripheral vascular disease
• Measure SBP in all four extremities
• Divide higher of 2 BP measurements in ankle by higher of 2 BP measurements in arms (highest ankle/highest arm)

Question 24

Question 26

If sphygmomanometer is to small...

Answer 26
