How many pills does the patient need to take each time for a 625 mg dosage of ibuprofen?

How can a patient achieve the 625 mg dosage of ibuprofen using pills that are 250 mg each? The patient needs to take 2 and 1/2 pills each time she wants the 625 mg dosage. By taking two full 250 mg pills and half of a 250 mg pill, the patient will reach the required dosage.

Calculating the Number of Pills Needed:

The patient is required to take 625 mg of ibuprofen twice daily. However, the pills available are 250 mg each. To determine how many pills the patient needs to take for each dosage, we must consider the following:

Step 1: Add the dosage required in one intake - 250 mg (1 pill) + 250 mg (1 pill) = 500 mg

Step 2: Since 500 mg is the closest total below 625 mg, the patient needs to take 2 full pills to reach 500 mg.

Step 3: Calculate the remaining dosage needed - 625 mg - 500 mg = 125 mg.

Step 4: Half of a pill is equivalent to 125 mg, so the patient also needs to take half a pill.

Therefore, the patient should take 2 full pills (500 mg) and half a pill (125 mg) to achieve the required 625 mg dosage of ibuprofen.
