Ch. 10 (heparin, CrCl, IBW)

Question 1

Cockcroft-gault equation for males

Answer 1

CrCl = (140 - age in years) x (weight) / 72 x serum creatinine (mg/dL)

Question 2

Cockcroft-gault equation for females

Answer 2

CrCl = 0.85 X CrCl determined using formula for males

Question 3

Jelliffe equation for males

Answer 3

CrCl = 98 - 0.8 X (patients age in years - 20)
/ serum creatinine in mg/dL

Question 4

Weights to use for calculating CrCl

Answer 4

Underweight (TBW < IBW) : Use TBW
Normal weight (TBW = IBW) : Use IBW
Overweight or Obese:
If BMI is GREATER than 25: use IBW
If BMI is LESS than 25: use (AdjBW)

Question 5

Ideal body weight for males (IBW)

Answer 5

IBW = 50 kg + 2.3 kg for each inch over 5 ft

Question 6

Ideal body weight for females (IBW)

Answer 6

IBW = 45.5 kg + 2.3 kg for each inch over 5 ft

Question 7

Body mass index (BMI)

Answer 7

BMI = Weight (kg) / height (m^2)

Question 8

Adjusted body weight (adjBW)

Answer 8

AdjBW = IBW + 0.4 (TBW - IBW)

Question 9

How many inches is 1 meter?

Answer 9

39.37 in
