Answer:

3 mg

Step-by-step explanation:

<h3>Step 2 of the attachment</h3>

<em>If the patient is less than 70 years old, the loading dose is 80 Howell Units </em>

<em>per kilogram of  DM. One Howell Unit is equivalent to 0.0020 mg of pure heparin.  </em>

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

  • 80*0.0020 = 0.16 mg per kg of DM
<h3>Step 3</h3>

<u>Let's calculate Dosing mass first, as per given formula:</u>

  • DM = LBM + (TBM - LBM)/3

As body fat is 10%,

  • LBM = 90% of TBM = 0.9*TBM

<u>As TBM is given = 40 lbs</u>

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

<u>Converting to kg</u>

  • DM = 37.33 Lb /2.2 = 16.97 kg

<u>Since dosing mass and dosing rate known, we can calculate loading dose:</u>

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

How do you do number 24?

Answer: k = 4

---------------------------------------------
---------------------------------------------

Explanation:

The piecewise function is essentially two different functions joined together. In this case,

h(x) = kx if 0 <= x < 1
OR
h(x) = x+3 if 1 <= x <= 5

The value of x determines which piece we use.

The two pieces will join together to be continuous only if the y value is the same for x = 1.

Plug x = 1 into the first piece and we get
h(x) = k*x
h(1) = k*1
h(1) = k

Do the same for the second piece
h(x) = x+3
h(1) = 1+3
h(1) = 4

Set the two results (k and 4) equal to each other and we get k = 4.
