Obviously dividing 17 into 2 goes zero times or will not go. So we then consider the next number (3) and ask the question how many times can 17 go into 23? Obviously the answer is once; twice 17 would equal 34. So, the answer is 1. 1 17 2 3 17 into 23 goes 1. Multiply 1 × 17. 1 7 Subtract the 17 from 23. 6 So the answer is 1 remainder 6. 6 This could also be expressed as 1 , but we would calculate to 2 or 17 more decimal places. 00000; therefore, we can continue to divide the number: 1 . 17 2 3 .

Multiply 1 × 17. 1 7 Subtract the 17 from 23. 6 So the answer is 1 remainder 6. 6 This could also be expressed as 1 , but we would calculate to 2 or 17 more decimal places. 00000; therefore, we can continue to divide the number: 1 . 17 2 3 . 0 1 7 Bring down the zero and put decimal point in the answer. indb 11 6 0 4/22/15 10:12 PM 12 Basics Then start the process again: 17 × 1 = 17 17 × 2 = 34 17 × 3 = 51 17 × 4 = 68 17 into 60 goes 3. 17 × 5 = 85 Multiply 3 × 17. 17 × 6 = 102 Subtract the 51 from 60.

If the answer you get is outside this range, then your answer is wrong and you should recheck your calculations. indb 37 4/22/15 10:12 PM 38 First principles The following guide may be useful in helping you to decide if your answer is reasonable. Any answer outside these ranges probably means that you have calculated the wrong answer. The maximum you should give a patient: Tablets Not more than 4 for any one dose* Liquids Anything from 5 to 20 mL for any one dose Injections Anything from 1 to 10 mL for any one dose Putting it all together Using all the above principles, consider the following situation: You have an injection of pethidine with the strength of 100 mg/2 mL and you need to give a dose of 60 mg.
