CardioPulm Quiz 1

Question 1

CV risk factor: Family History

Answer 1

Primary Male relative < 55
Primary Female relative <65
Hx of MI, revascularization procedure, sudden cardiac death, etc.

Question 2

CV risk factor: Smoking

Answer 2

Within past 6 months,

OR this with environmental exposure

Question 3

CV risk factor: HTN

Answer 3

SBP > 140
DBP >90
Taking HTN meds
*Measured twice

Question 4

CV risk factor: Age

Answer 4

Males >45

Females >55

Question 5

CV risk factor: Hypercholesterolemia

Answer 5

Total >200
LDL > 130
HDL < 40

HDL > 60 is a -1 risk factor

*if no data, give one point

Question 6

CV risk factor: Prediabetes

Answer 6

Fasting glucose >100

If no data, give one point if >45 AND BMI >25

Question 7

CV risk factor: Sedentary

Answer 7

<30 minutes cumulative moderate exercise 3 times/wkf or 3 months

Question 8

CV risk factor: BMI

Answer 8

BMI > 30

Question 9

Classification of Light Exercise

Answer 9

30-39% VO2 reserve

3 METS

Question 10

Classification of Moderate Exercise

Answer 10

40-59% VO2 reserve
3-6 METS
“noticeable” increase in HR and breathing

Question 11

Classification of Vigorous Exercise

Answer 11

> 60% VO2 reserve
6-10 METS
“substantial” increase in HR and breathing

Question 12

VO2 at rest

Answer 12

3.5 ml/kg/min = 1 MET

Question 13

Average VO2 max

Answer 13

35 ml/kg/min = 10 METs

Question 14

Calculating HR/VO2 reserve

Answer 14

HR/VO2 max - HR/VO2 at rest

Question 15

Criteria for maximal exercise testing

Answer 15

Use >50% total muscle mass
Be continuous and rhythmical
Prolonged (aerobic)
Standardized conditions

Question 16

Assumptions made when using submaximal GXT to predict CP function

Answer 16

Steady HR is obtained at each work rate
Linear relationship between HR and VO2
Max HR for a given age is uniform*
Mechanical efficiency (VO2 at given work rate) is same for everyone*
*Not valid

Question 17

Karvonen method for calculating target HR/VO2

Answer 17

Target = (intensity %)(max-rest) + rest
Target = (intensity %)(reserve) + rest
