Common Registration Assessment, Part 1

Ramipril titration packs and tablet strengths for the GPhC assessment

Three original practice questions, with the working shown. Read the stated prescription or plan before calculating.

The NHS describes a starting dose between 1.25 mg and 2.5 mg once a day, increased gradually over a few weeks. When starting, some people are prescribed a pack containing tablets of three strengths: 2.5 mg, 5 mg and 10 mg.

The maximum dose is 5 mg twice a day or 10 mg once a day. Titration schedules change strength over time, so the week-by-week quantity depends on the plan stated.

Each question fixes the values needed for its arithmetic. Write the unit beside every step and keep each titration week separate. All prescriptions and patients here are fictional; these are revision materials, not for patient care.

The method

  1. Identify the exact strength, dose and frequency supplied for each stage of the plan.
  2. Calculate the quantity for one stage before combining stages.
  3. For tablets divide prescribed mg by mg per tablet.
  4. Add stage quantities only when a total supply is requested.
  5. Check any dose against a stated maximum before reporting it.

Three practice questions

Work each one on paper first, then open the answer. All patients and prescriptions are fictional.

Question 1

A fictional titration plan specifies ramipril 2.5 mg once a day for week 1, 5 mg once a day for week 2 and 10 mg once a day for week 3, using tablets of exactly those strengths. How many tablets does the 3 week plan use in total?

Show the answer

Answer: 21 tablets

Working: One tablet a day for 7 days per stage: 7 + 7 + 7 = 21 tablets.

Question 2

A fictional prescription specifies ramipril 10 mg once a day using 5 mg tablets. How many tablets are needed for 28 days?

Show the answer

Answer: 56 tablets

Working: 10 ÷ 5 = 2 tablets a day. 2 × 28 = 56 tablets.

Question 3

A fictional prescription specifies the maximum schedule of ramipril 5 mg twice a day using 2.5 mg tablets. How many tablets is one day?

Show the answer

Answer: 4 tablets

Working: 5 ÷ 2.5 = 2 tablets per dose. 2 × 2 doses = 4 tablets a day.

Exam approach

A titration plan is several small supply calculations, not one. Fix the strength and duration of each stage, calculate, then add.

Where marks are lost

  • Adding stage quantities before working out each stage separately.
  • Using a remembered starting dose instead of the stated one.
  • Treating arithmetic as evidence that a real prescription is clinically suitable.

Frequently asked questions

Are these official assessment questions?

No. They are original revision exercises, not official GPhC questions and not for patient care.

Do titration packs change the calculation?

Only the stated strengths and schedule matter. Work each stage on its own, then combine.

How should I check the answer?

Check the requested unit, then work backwards from the quantity to the stated dose and duration.
