A. Calculate the total dose in cubic centimeters of a drug, to be administered SQ to a patient weighing 17 pounds. The concentration of the drug is 2mg/ml and the dosage rate is 10mg per kg._____________

B. Calculate the total dose in cubic centimeters of a drug, to be administered SQ to a patient weighing 99 pounds. The concentration of the drug is 100mg/ml and the dosage rate is 15mg per kg.___________

Answer 1

19. Answer ; 20.35 cc

Here the weight of the patient is 81 pounds that is 37 kg.
The dosage rate is 11 mg per kg, So for 37 kg it would be 37 x 11 = 407 mg.
Therefore the client need to have 407 mg.

Here the concentration of the drug is 20 mg per mll, that is 20 cc per ml.

So for 407 mg, it would be 407 / 20 = 20.35 cc

A. Answer ; 40 cc

The given weight of the patient is 17 pounds, that is 8 kg.
The ordered dose is 10 mg per kg, therefore for this patient it would be 10 x 8 = 80 mg.

The available dose concentration is 2 mg per ml, that is 2 cc per ml.

So in order to administer 80 mg, it would be 80 / 2 = 40 cc

B. Answer; 6.75 cc

According to given info, the patient weight is 99 pounds, which means 45 kg of weight
Here the ordered dose is 15 mg per kg, hence for 45 kg it would be, 45 X 15 = 675 mg.

The available concentration of that drug is 100 mg per cc
So in order to give 675 mg, it would be 675/100 = 6.75 cc
