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.
