Someone please please help me! I only need help on the third question. To answer the third question you need this answer which is 0.16mg heparin/1kg. Which is the answer to the second question. For the third question, you need to convert 40 lbs to kg which comes out to 18.14 kg. From then on I have no idea what to do.

Answer:

3 mg

Step-by-step explanation:

Step 2 of the attachment

If the patient is less than 70 years old, the loading dose is 80 Howell Units

per kilogram of  DM. One Howell Unit is equivalent to 0.0020 mg of pure heparin.  

2. Calculate how many mg of pure heparin is in 80 Howell Units

  • 80*0.0020 = 0.16 mg per kg of DM

Step 3

Let's calculate Dosing mass first, as per given formula:

  • DM = LBM + (TBM - LBM)/3

As body fat is 10%,

  • LBM = 90% of TBM = 0.9*TBM

As TBM is given = 40 lbs

  • DM = 40 *0.9 + ( 40 - 40*0.9)/3 = 37.33 lbs

Converting to kg

  • DM = 37.33 Lb /2.2 = 16.97 kg

Since dosing mass and dosing rate known, we can calculate loading dose:

  • 16.97 kg *0.16 mg/kg = 2.7152 mg ≈ 3 mg as it is asking dose in mg
