The IV dose of mannitol is 1.5g/kg, administered as a 15% solution. How many mls of the solution should be administered to a 150 pound patient?
I assume you're taking a nursing class. If so, why have you posted these questions to a bunch of strangers who don't have medical backgrounds? Are you sure you want to be a nurse?
My apologies to Ms. Sue, but your assumptions are not correct. i just need help on my math homework, for I am mathematically impaired and any help is much appreciated.
If you're "mathematically impaired," why are you taking this class? What do you hope to do with this credit?
I suggest you post your answers. Then we can help you better by knowing your thinking and calculations for these problems.
To determine how many mLs of the 15% mannitol solution should be administered to a 150 pound patient, we need to follow these steps:
Step 1: Convert the patient's weight from pounds to kilograms.
Since we know that 1 kg is equal to 2.2 pounds, we can calculate as follows:
150 pounds / 2.2 = 68.18 kilograms (rounded to two decimal places)
Step 2: Calculate the dose of mannitol in grams using the weight in kilograms.
The IV dose of mannitol is 1.5g/kg, so we multiply this by the weight in kilograms:
1.5g/kg * 68.18 kg = 102.27 grams (rounded to two decimal places)
Step 3: Calculate the volume of the 15% mannitol solution needed.
The concentration of the mannitol solution is given as 15%. This means that there are 15 grams of mannitol in 100 mL of solution.
To calculate the volume needed, we can use the following proportion:
15 grams / 100 mL = 102.27 grams / x mL
Cross-multiplying:
15x = 102.27 * 100
15x = 10227
Divide both sides by 15:
x = 10227 / 15
x = 681.8 mL (rounded to one decimal place)
Therefore, approximately 681.8 mL of the 15% mannitol solution should be administered to the 150 pound patient.
