Therefore, the final volume will be 2 + 3. You discuss the issue with the parent and explain that you can prepare the paediatric linctus by diluting the strong version. Example: Suppose you diluted 2 liters of juice with 3 liters of water, calculate the dilution factor. The paediatric version has been out of stock for three months and you only have the strong version of pholcodine linctus available. The out-of-hours GP has prescribed 150mL of paediatric pholcodine liquid for a girl aged 11 years, with the directions to give two 5mL spoonfuls three times per day.

are compounded when preparing a series of dilutions (or serial dilutions) it.
It is late on a Saturday evening and a parent hands you a prescription. To do this, you need to figure out the overall dilution youre aiming for. Solution: To solve a problem with serial dilutions, we first must find the dilution factor of each dilution using the equation: Dilution Factor Equation. Example 1: Paediatric concentrations and dilutions Question: Please note that these exact questions will not be included in the assessment. The following questions and answers are provided as examples only and are included to give you an idea of the types of question that will be asked during the registration assessment.

In the following videos, Simon Harris, head of education at Greenlight Campus, provides trainees with a step-by-step walk through of how to solve three example calculations covering concentrations, dilutions and health economics. The ability to do so correctly is assessed by the General Pharmaceutical Council in line with the registration assessment framework.
