Final answer:
To determine the number of tablets, divide the prescribed dose of 150 mg by the strength of the stock tablets, which is 600 mg. This calculation results in 0.25, meaning the patient will take one quarter of a 600 mg scored tablet per dose.
Step-by-step explanation:
To calculate the number of tablets a patient should take per dose, we need to compare the prescribed dosage with the dosage available per tablet. The question states that the patient needs a 150 mg dose of medication ABC and the stock available is in 600 mg scored tablets. A scored tablet means that the tablet can be divided. Therefore, dividing the stock tablet's dosage by the prescribed dosage gives the fraction of the tablet needed.
So, to find out how many tablets are needed for a 150 mg dose:
- Divide the prescribed dose (150 mg) by the stock tablet's dose (600 mg).
- 150 mg / 600 mg = 0.25
Thus, the patient will take 0.25 or a quarter of a scored 600 mg tablet per dose.
