8) D = 750 H = 250 Q = 2. Using the formula method, calculate the proper dose

Answer 1

Solution 1: It is given 100 mg present in 1ml

100mg is present in 1ml

Therefore, 1000mg will be present in 1000/100

= 10ml.

Solution 2:  

100mg is present in 1ml

Therefore, 200mg will be present in = 200/100

= 2ml

Solution 3:

Weight of the patient = 54 lbs.

So, weight of the patient in kilogram= 54/2.205 = 24.494 kilogram.

Ordered drug = 20mg/kg/dose.

So, 24.494 × 20 = 485.88 mg.

Solution 4:

Ordered drug = 200mg

Available drug = 100mg / 2ml

So, 100 mg of the drug is present in 2ml

Therefore, 200mg of drug will be present in = 200 ×2 = 400

400÷ 100 = 4ml.
