A client who is experiencing indigestion receives a prescription for magnesium hydroxide 1200 mg by mouth every 6 hours. The bottle is labeled "Magnesium Hydroxide, USP 400 mg per 5 mL." How many ounces should the nurse instruct the client to take with each dose? (Enter numerical value only.)

The client receives a prescription for magnesium hydroxide 1200 mg by mouth every 6 hours. The bottle is labeled "Magnesium Hydroxide, USP 400 mg per 5 mL", so the client should take 15 mL of medication with each dose (1200 mg / 400 mg/5 mL * 5 mL). Since 1 ounce is equivalent to 29.5735 mL, the client should take 0.51 ounces of medication with each dose (15 mL / 29.5735 mL/ounce).
