Cardio Values

Question 1

SpO2

Answer 1

95 - 100%

Question 2

PaO2

Answer 2

80 - 100 mmHg

Question 3

PaCO2

Answer 3

35 - 45 mmHg

Question 4

pH, whole blood

Answer 4

7.35 - 7.45

Question 5

Prothrombin Time (PT)

Answer 5

11 - 15 secs

PT contraindicated if clotting time is 2.5 time or more than normal.

Question 6

International Normalized Ratio (INR)

Answer 6

Ratio of patient’s PT to reference range 0.9 - 1.1 (ratio)

INR < 2 = desirable
INR > 2 = consult with MD for incr. risk of bleeding
INR > 3 = risk of hemarthrosis

Question 7

White Blood Cells

Answer 7

4,300 - 10,800 cells/mm3

> 5,000 = light exercise only
< 5,000 = with fever, exercise is contraindicated
< 1,000 = use mask, standard precautions

Question 8

Red Blood Cells

Answer 8

Male: 4.6 - 6.2
Female: 4.2 - 5.9

Question 9

Erythrocyte Sedimentation Rate (ESR)

Answer 9

Male: < 15 mm/hr
Female: < 20 mm/hr

Question 10

Hematocrit (HCT)

Answer 10

Male: 45 - 52%
Female: 37 - 48%

> 25% but less than normal = light exercise only
< 25% = exercise contraindicated

Question 11

Hemoglobin (Hgb)

Answer 11

Male: 13 - 18 g/dL
Female: 12 - 16 g/dL

8 - 10 g/dL = light exercise only
< 8 g/dL = exercise contraindicated

Question 12

Platelet count

Answer 12

150,000 - 450,000 cells/mm3

< 20,000 = AROM, ADLs only
20,000 - 30,000 = light exercise only
30,000 - 50,000 = moderate exercise
