Chapter 1
Calculating children’s medicines
Chapter aims
By the end of this chapter, you should be able to:
- estimate what a reasonable dose would be;
- demonstrate a sound understanding of the metric system and SI units of mass and volume;
- calculate paediatric drug doses;
- calculate rates for intravenous fluids;
- demonstrate an awareness of professional decision making when administrating medicines.
Case study
Many years ago, as a fairly newly qualified children’s nurse on night duty, I was dealing with a seriously ill baby admitted with meningitis and was supporting a consultant paediatrician and a doctor who was relatively inexperienced in paediatrics. The consultant asked me to prepare the intravenous antibiotics, but the less experienced doctor insisted he would do this himself and did not require my help. The drugs were prepared and administered to the baby by the less experienced doctor swiftly, as the situation warranted, without checking with me or the consultant. As soon as the baby was stabilised, I started tidying up the treatment area, including the drugs used, and picked up an empty gentamicin vial and asked the doctor where it had all gone. He immediately realised his error, as he had mistakenly administered the whole vial to the baby, which was four times the recommended dose. Thankfully the baby recovered, but needed very close monitoring for drug toxicity, which could lead to kidney damage and hearing loss.
Introduction
The above case study highlights the important factors children’s nurses should be aware of when calculating and administering medicines to children. Unlike for most adult patients, children’s doses need to be calculated on an individual basis according to their age, weight or body surface area. A drug miscalculation in a child can have catastrophic effects and all care needs to be taken to avoid this. As a children’s nurse you must have an awareness of what a sensible dose would be for the children in your care, and guide other professionals and parents. You need to be confident and skilled in your ability to calculate doses in all situations.
This chapter will start by reviewing the metric system in order that you are able to understand the basic units of measurement used in the prescribing of drugs and how drug strengths are expressed, including percentages and units. You should feel comfortable about converting from one unit of measurement to another, and understand the terms of expression in medicines. As most drugs are prescribed according to a child’s weight, converting weights from imperial to metric will be covered and vice versa, including methods of estimating a child’s weight in an emergency situation. This will help you always to have in mind what is a sensible estimate of weight at different ages, so you can be confident the recorded weight on the child’s drug chart is correct.
The chapter covers the calculation of tablets and capsules, and the more commonly used liquid medicines and intravenous fluids, and how to work out if the prescribed dose or rate is correct for the child. It is essential that the children’s nurse administering the dose is capable of checking the calculation and has an awareness of what a reasonable dose would be. Throughout the chapter there will be worked examples in order to demonstrate the methods used and activities for you to practise the skills needed to gain competence.
The metric system
In order to calculate medicine dosages safely, it is essential to have a clear understanding of the units of measurements used in the prescribing and dispensing of drugs. The strength of medicines should always be expressed using the standard metric system of weights and measures. The basic units used in clinical practice derive from the Système International (SI). The SI units for weight (mass) are shown in Table 1.1 and those for volume in Table 1.2.
Note that nanograms and picograms are rarely used in clinical practice.
The terms ‘micrograms’, ‘nanograms’ and ‘picograms’ should NOT be abbreviated but always written in full. This is to prevent medication error attributable to abbreviations. Abbreviating micrograms as µg (the official abbreviation for microgram in the SI system) can be mistaken for mg and lead to a one thousandfold dosage error.

Table 1.2: The SI units for volume
Note that the term ‘millilitre’ (ml or mL) is used in medicine and pharmacy rather than cubic centimetre abbreviated as ‘cc’, as this can be mistaken for ‘u’ (units) when poorly written.
The term ‘litre’ is generally not abbreviated to avoid error. It is safer to express volume in millilitres in order to avoid the unnecessary use of...
