A child with juvenile idiopathic arthritis weighs 20 kg. The prescriber has written ibuprofen 30 mg/kg daily, to be given in 3 equal doses spread through the day. The pharmacy stocks ibuprofen oral suspension 100 mg/5 mL (sugar free). What volume of suspension should the parent measure for each single dose? Give your answer in mL to one decimal place.
Worked solution
Total daily dose = 20 kg x 30 mg/kg = 600 mg Each dose = 600 mg / 3 doses = 200 mg Strength per mL = 100 mg / 5 mL = 20 mg/mL Volume per dose = 200 mg / 20 mg/mL = 10 mL (one decimal place)

THE REVISION PROBLEM
A question is only
the beginning.
Keep the answer, its source and your next review in view.

Follow the source.
Each written question names the source its answer key is based on, such as the BNF, NICE, the MHRA or a medicine's SmPC, and most quote the passage. Calculation questions show a worked solution instead.

How are the answers checked?
The questions are drafted with the help of AI tools. Most answer keys have also been checked by a second AI model, a different one from the model that drafted the question, which looked at whether the quoted passage supports the key. That check does not show the key is right, and some keys have not had it yet. Apart from a few corrected by hand, no answer key has been checked by a person, and none by a pharmacist. Check anything that matters against the source shown, and report any question that looks wrong.
Is PharmRevise connected with the GPhC?
No. PharmRevise is an independent revision tool. It is not affiliated with, endorsed by or a source of official information about the General Pharmaceutical Council or its registration assessment, and its questions are not the GPhC's questions. Check the GPhC's own website for anything that decides your registration.

PrivacyDoes a PharmRevise score predict my assessment result?
A PharmRevise score does not predict your result.
No. Score ranges, study plans and suggestions in PharmRevise are estimates about your revision on PharmRevise questions. They do not predict your result in the registration assessment and are not connected with the GPhC.
Can I use PharmRevise in practice?
No. PharmRevise is for exam revision only and is not clinical advice. Do not use it to make any decision about a real patient. In practice, work from the current BNF, NICE guidance, the product's SmPC, professional guidance and the people supervising you.
