Q

Angina pain scale 3

A

Moderately severe, very uncomfortable

22
Q

Angina pain scale 4

A

Most severe or intense pain ever experienced

23
Q

ABI procedure

A
  • 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)
24
Q

Bladder size of sphygmomanometer for child under 13

A

encircle 100% of arm

25
Q

Bladder size of sphygmomanometer for adult

A

encircle 80% of arm

26
Q

If sphygmomanometer is to small…

A
  • BP reading may be false high

- When in doubt, use larger cuff

27
Q

How high do you inflate sphygmomanometer?

A

above anticipated systolic pressure (>200???)

28
Q

Rate of deflating cuff

A

2-3 mmHg/second

29
Q

BMI calculation

A

1) weight (kg)/ height (m^2)

2) weight (lb)/ height (in^2) x 703

30
Q

Underweight Adult BMI

31
Q

Normal Adult BMI

A

18.5 - 24.9

32
Q

Overweight Adult

A

25.0 - 29.9

33
Q

Obesity (Class 1) Adult

A

30.0 - 34.9

34
Q

Obesity (Class 2) Adult

A

35.0 - 39.9

35
Q

Extreme Obesity (class 3) Adult

A

> or equal to 40.0

36
Q

BMI Children and adolescents

A

1) BMI between 85th - 95th percentile for age and sex = at risk for becoming overweight
2) BMI > or equal to 95th percentile considered overweight or obese

37
Q

Normal capillary refill time

A

< 2 seconds; full color returns

38
Q

Abnormal capillary refill time

A

< 2 seconds; indicates capillary compromised (eg. arterial occlusion, hypovolemic shock, hypothermia)

39
Q

Normal infant HR

A

100-130 beats/min

40
Q

Normal child HR

A

80-100 beats/min

41
Q

Normal adult HR

A

60-100 beats/min

42
Q

Bradycardia

A

< 60 beats/min

43
Q

Tachycardia

A

> 100 beats/min

44
Q

Large bounding pulse

45
Q

normal average pulse

46
Q

small or reduced pulse

47
Q

absence of pulsation

48
Q

Lower Target heart rate using % of HR max

A

Lower THR = HRmax x 55%

49
Q

Upper Target HR using & of HR max

A

Upper THR = HRmax x 90%

50
Q

Lower Target HR using Karvonen formula

A

Lower THR = ([HRmax - HRrest) x 40%] + HRrest

51
Q

Upper Target HR using Karvonen formula

A

Upper THR = ([HRmax - HRrest) x 85%] + HRrest
