I have 3 problems which needs to be addressed:

1. Order: Heparin 45,000 units IV in 500 ml D5W. Available: Heparin labeled

10,000 units/ml. How many milliliters will you add to the IV?

2. Order: KCL 20 mEq in 500 ml D5W to infuse over 8 hours. How many milliliters

will you add to the IV?

3. Order: Zithromax 320 mg po daily. The label on container says, " 200 mg per 5

ml. " What is the dosage?

Thanks

Abe

Dear Abe,

I was going through to find posts that may not have been answered.

I am not sure why my posting did not show so I will try it again:

1. Order: Heparin 45,000 units IV in 500 ml D5W. Available: Heparin labeled

10,000 units/ml. How many milliliters will you add to the IV?

Ratio/Proportion:

10,000 units----45,000 units

------------ = -------------

1ml--------------X ml

1 x 45,000

---------- = X ml

10,000

4.5 ml = X ml

2. Order: KCL 20 mEq in 500 ml D5W to infuse over 8 hours. How many milliliters

will you add to the IV?

You must know that KCl is 2 meq per ml

2 meq ------20 meq

------- = --------

1 ml -------X ml

1 x 20

------- = X ml

2

10 ml = X ml

3. Order: Zithromax 320 mg po daily. The label on container says, " 200 mg per 5

ml. " What is the dosage?

200 mg-----320 mg

------- = --------

5 ml-------X ml

5 x 320

------- = X ml

200

8 ml = X ml

Hope this helps,

Sorry about the delay!
