Final answer:
To administer 10mg of medication C using 4 mg tablets, divide 10 mg by 4 mg per tablet to get 2.5, which rounds up to 3 tablets to provide the required dosage.
Step-by-step explanation:
To determine how many 4 mg scored tablets are needed to give 10mg of medication C, you will need to do some simple division. Since each tablet contains 4 mg, you can divide the total dosage required, which is 10 mg, by the amount per tablet, which is 4 mg.
10 mg ÷ 4 mg/tablet = 2.5 tablets
Since you cannot give half of a scored tablet, you would round up to the next whole number, because medication dosages typically cannot be rounded down. Therefore, you would have to give 3 tablets to ensure that the patient receives at least 10 mg of medication C.
