The healthcare provider prescribes magnesium hydroxide 4800 mg by mouth at bedtime for a client with constipation. The bottle is labeled 'Magnesium hydroxide Saline Laxative, 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 correct answer is 2 ounces. To find the answer, we can use the following steps: Calculate the volume of magnesium hydroxide in mL by dividing the dose in mg by the concentration in mg/mL. Convert the volume in mL to ounces by multiplying by 0.0338. Round the result to the nearest whole number. Using these steps, we get: (volume in mL) = (4800) / (400) = 12 mL. (volume in ounces) = (12) x (0.0338) = 0.4056 ounces. (rounded volume in ounces) = 2 ounces. Therefore, the nurse should instruct the client to take 2 ounces of magnesium hydroxide Saline Laxative, USP with each dose.
