Question

I only need help on the third problem. The second problem that is already answered is needed to solve the third problem.

This is the formula I need to follow for the third question.

D? = ??? + ( ??? − ??? ) divided by 3

Where TBM is the total body mass and LBM is the lean body mass. Do not let all these letters confuse you. Just remember DM is the dosing mass so this will end up being a number to put in another formula below. LBM is a number you would find out from a patient you might be about to give Heparin. And TBM is the same. We use these letters to remind us what those quantities represent.

2. If the patient is less than 70 years old, the loading dose is 80 Howell Units2 per kilogram of DM. One Howell Unit is equivalent to 0.0020 mg of pure heparin. Calculate how many mg of pure heparin is in 80 Howell Units. Do not worry about the kilograms of DM yet.

Answer: 0.16mg heparin/1kg

You need this to answer the third question. Which I do not get.

I was told to convert 40 lbs to kg which I did and it comes out to 18.14 kg. I am not sure if this is the right step.

3. Now that we know how much Heparin is needed for each kg of dosing mass, we can now figure out how much Heparin to give someone. 3. Calculate the loading dose, in mg of heparin for a 5-year-old with a total body weight of 40 lbs., with 10% body fat (that is, 90% of that 40 lbs. is lean body mass). You may also be interested to know that 1 kg = 2.20 lbs. Think about the steps you need to go through to find the correct dose. Remember, first you need to find the dosing mass
