Question 14

BUN / Creatinine ratio

Answer 14

10:1 - 20:1

Question 15

Platelet count exercise guidelines

Answer 15

< 10,000 usually transferred
<20,000: ADLs, AAROM - AROM (no antigravity/resistive ex. Guard carefully)
20,000 - 30,000: Light ex (no PROM); light AROM; walking as tolerated
30,000 - 50,000: AROM; submax isometrics; stationary bike; walking as tolerated; aquatics; NO prolonged stretches or resistive exercises
50,000 - 150,000: Min-Mod resistive ex; sexual intercourse; MMT w/o restrictions; swimming; low bench stepping; bicycling w/o grade
> 150,000: unrestricted

Question 16

Hemoglobin exercise guidelines

Answer 16

< 8: No exercise (red flag to discuss w/ physician)
8 - 10: Light exercise permitted; no aerobics
10 - 12: Low-impact and low-intensity aerobics (stationary bike), isometrics, and resistive ex permitted

Question 17

Hematocrit exercise guidelines

Answer 17

< 25%: no exercise

> 25%: light ex permitted, progression to resistive exercise when Hct reaches 30%

Question 18

WBC count exercise guidelines

Answer 18

< 5,000 with fever: No exercise permitted

> 5,000: Light exercise permitted w/ progression to resistive ex

Question 19

Glucose: hypoglycemia

Answer 19

< 60 mg/dL, or a sudden drop of elevated levels for individuals w/ diabetes

Question 20

Normal fasting glucose

Answer 20

60 - 110 mg/dL

ACSM values: 60 - 99

Question 21

Glucose: diabetic border

Answer 21

> 126 mg/dL (measured on 2 different days)

Question 22

Glucose: red flag levels

Answer 22

< 70 mg/dL or > 250 mg/dL at the start of exercise

300 - > 350 mg/dL: risk of diabetic ketoacidosis

Question 23

A1C normal reference range

Answer 23

4% - 6%
Goal is to maintain consistent levels below 7% (correlates to average daily level below 170 mg/dL. A1C above 10% require immediate insulin therapy)
