| show | H : V (known) = D : X (desired)
H = dosage or supply on hand
V = indicates the vehicle
D = reflects the desired dosage
X = denotes the amount to be given

| show | H= 4mg, V= 1mL, D= 2mg, X= amount to administer
4 : 1 :: 2 : x (multiply means and extremes)
4x :: 2
x :: 1/5
0.5 mL administered to patient

| show | H= 250mg, V= 5mL, D= 375mg, X= amount to administer
250 : 5 :: 375 : x (multiply means and extremes)
250x :: 1,875
x :: 7.5
7.5mL administered to patient
🗑

| show | 1. The drug label factor is called V, the medication that the nurse must administer
2. The conversion factor lets nurses set up the equation with the conversions needed to calculate the dose
3 The drug order factor indicates the desired dose to be given

| What is the Dimensional Analysis and Factor Labeling method for medication dosage? | show 🗑
|
||||
| show | H= 250mg, V= 1 capsule, D= 500mg, X= number of capsules to administer
X(capsules) = 1 cap / 250mg x 1/1 x 500mg/1
X(capsules) = 0.004 x 1 x 500
X = 2
2 capsules administered to patient

| show | Answer 20.
H= 250mg, V= 5mL, D= 1g, C= 1000mg/1g
X= 5mL/250mg x 1000mg/1g
X= 0.02 x 1000
X= 20
20mL to be given to patient
