A 187-pound client has a subdural hematoma and finds increased intracranial pressure. How many milliliters should the nurse prepare to administer of mannitol?

• A. 85 mL
• B. 100 mL
• C. 75 mL
• D. 50 mL

Answer: (A)

To determine the amount of mannitol a nurse should prepare for a client with a subdural hematoma and increased intracranial pressure, it's essential to consider the typical dosing for mannitol, which is administered based on body weight. Mannitol is an osmotic diuretic used to reduce intracranial pressure by drawing fluid out of the brain tissue and into the bloodstream. The common dosage for mannitol is 0.25 to 1 gram per kilogram of body weight. For a 187-pound client, converting the weight to kilograms (1 pound = 0.453592 kg) results in approximately 85 kilograms. If using a typical calculation for a moderate dose of mannitol at 1 gram per kilogram, the calculation would be as follows: 85 kg x 1 g/kg = 85 grams of mannitol. Since mannitol is delivered in a solution form that typically has a concentration of 20%, each 100 mL of this solution contains 20 grams of mannitol. Therefore, to find how many milliliters correspond to 85 grams, the nurse would calculate: 85 grams ÷ (20 grams/100 mL) = 425 mL. However
