Problem:
Amlodipine is available in 2.5 mg and 10 mg tablets.
- How many tablets of each dosage (2.5 mg and 10 mg) will Nurse Jamie need to give to Oscar to fulfill the daily prescription of 5 mg?
- If Nurse Jamie can only give whole tablets, what combination of tablets should she use to ensure Oscar receives the correct dose without exceeding it?
Solution Steps:

-
Calculation of 10 mg tablets:

5 mg ÷ 10 mg/tablet = 0.5 tablets (which cannot be given, as only whole tablets may be used)
- To administer 5 mg using 10 mg tablets:
Answer: Nurse Jamie should give 2 tablets of the 2.5 mg Amlodipine to ensure Oscar receives the correct daily dose of 5 mg.
