Final answer:
To fulfill the 0.5 g methyldopa prescription with 250 mg tablets, 2 tablets should be administered.
Step-by-step explanation:
The client is prescribed methyldopa (Aldomet) 0.5 g, which is equivalent to 500 mg (since 1 g = 1000 mg). The pharmacy provides tablets containing 250 mg each. To calculate the number of tablets, we divide the prescribed dosage (500 mg) by the dosage available per tablet (250 mg).
Number of tablets = ∂ prescribed dosage / dosage per tablet = 500 mg / 250 mg = 2 tablets.
Therefore, you would administer two 250 mg tablets to the client.
