Calculations

Question 1

Dilution Formula

Answer 1

C1V1=C2V2
C1=Concentration 1
C2 = Concentration 2
V1 = Volume 1
V2 = Volume 2

Question 2

Formula for how to calculate dose in MG

Answer 2

Dose (mg) = weight (kg) x dosage (mg/kg)

Question 3

Formula for how to calculate volume (ml)

Answer 3

Volume (mL) = dose (mg) / concentration (mg/ml)

Question 4

Formula for how to calculate dose in tablets

Answer 4

Dose (tablets) = dose (mg) / concentration (mg/ml)

Question 5

How to Calculate both dose and volume

Answer 5

1. Dose (mg) = weight (kg) x dosage (mg/kg)
2. Volume (mL) = dose (mg) / concentration (mg/mL)

Question 6

Convert lb to kg and vice versa

Answer 6

lb = kg x 2.2
kg = lb / 2.2

Question 7

Convert mL into L and vice versa

Answer 7

mL = L x 1000
L = mL / 1000

Question 8

Convert mcg to mg to g

Answer 8

mcg = mg x 1000
mg = g x 1000
g = mg / 1000
mg = mcg / 1000

Question 9

RER Formula

Answer 9

RER (kcal) = 7- x weight (kg)^0.75

Question 10

MER Formula

Answer 10

MER (kcal) = activity or illness factor x RER

Question 11

Food Requirement Formula

Answer 11

Food requirement = MER (kcal requirement) / caloric density of food

Question 12

Flow Rate Formula

Answer 12

Flow Rate (mL/hr) = total volume (mL) / infusion time (hr)

Question 13

Infusion Time Formula

Answer 13

Infusion Time (hr) = total volume (mL) / flow rate (mL/hr)

Question 14

Total Volume formula

Answer 14

Total Volume (mL) = flow rate (mL/hr) / infusion time (hr)

Question 15

Steps for Calculation Fluid Rates

Answer 15

1. Calculate flow rate
2. Calculate Infusion Time
3. Calculate Total Volume
4. Calculate Drip Rate

Question 16

Drip Rate Formula

Answer 16

Drip rate (gtt/min) = (volume in mL)(gtt/mL) / (time in seconds)(3600)
