How many scored tablets of Glucophage (2 g each) are needed when 1000 mg is ordered b.i.d.?

To determine how many scored tablets of Glucophage (2 g each) are needed for an order of 1000 mg b.i.d. (twice daily), it's essential to start by converting the ordered dosage into the same unit as the tablet strength.

1. The prescribed amount is 1000 mg.

2. Converting milligrams to grams, we recognize that 1000 mg is equivalent to 1 g.

3. The strength of each scored tablet is 2 g.

Since the order is for 1 g but each tablet contains 2 g, it becomes evident that one tablet exceeds the ordered amount. The only way to fulfill the dosing requirement without giving excess medication is to utilize no tablets at all. Therefore, zero tablets are required to safely meet the dosage of 1000 mg b.i.d.

In this context, the correct answer is that no scored tablets of Glucophage are needed to fulfill the prescribed order, ensuring the patient's safety by avoiding an unnecessary administration of the medication.
