A nurse is preparing to administer mannitol 0.2 g/kg IV bolus over 5 minutes as a test dose to a client who has severe oliguria. The client weighs 198 lb. How many grams of mannitol should the nurse administer?

A) 4.0 grams
B) 8.0 grams
C) 9.0 grams
D) 19.8 grams

Answer :

Final answer:

The correct dosage of mannitol for a patient weighing 198lb (90kg) is 18g based on the dosage of 0.2g/kg. However, none of the provided answers matches this result.

Explanation:

The subject of this question is dose calculation. The weight of the patient is given in pounds, but the dose of mannitol to be administered is defined in terms of grams per kilogram. We first need to convert the weight in pounds to kilograms because the medication dosage is based on weight in kilograms, not pounds.

There are approximately 2.2 pounds per kg, so: 198 lb ÷ 2.2 = 90kg approximately.

The dose to administer is 0.2 g/kg. So, you need to multiply the patient's weight in kg by 0.2g. So: 90 kg x 0.2 g/kg = 18.0 grams. However, none of the given choices matches the calculated answer, probably this could be a typo mistake or an error.
