Final answer:
The client should take 1.5 tablets per dose of allopurinol (Zyloprim) 450 mg.
Step-by-step explanation:
To determine the number of tablets the client should take per dose, we need to calculate how many tablets make up the dosage of 450 mg. The bottle contains 300 mg scored tablets, so to calculate the number of tablets, we divide the total dosage (450 mg) by the dosage per tablet (300 mg). This gives us:
450 mg / 300 mg = 1.5 tablets
Therefore, the client should take 1.5 tablets per dose. Since the tablets are scored, the client can take one whole tablet and half of another tablet to get the correct dosage.
