Well it was 50 questions. I figured out the other 47. I just figured out

#3.I divided 100 ML by 3.75 ml to get the 26 doses.

I'm still trying to get the other 2.

What chare is asking is for you to show us what you've done to try to find the answer. How are you setting up your equations? Which equations are you trying to use?

1.)The doctor orders and IV: NS 1.5 mEq KCL/100 ml of IV fluid at 86 ml/hr.

Medicine info:

The IV bag is a 1000ml. The vial of KCI is 20 meq,with a concentration of 2 mEq/ml.

A) How many mEq of KCI should be added to the with the IV bag? Answer:15

1.5meq x

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

100ml 1000ml

X would be the number of meq needed.

100X ml = 1,500 meq/ml

X = 1,500 meq/ml

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

100ml

X = 15meq

B) How many ml of KCL would you add to the bag?

Answer: 7.5 ml

2meq 15meq (required dose)

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

ml X (amount needed)

15meq/ml

X = ----------

2meq

X = 7.5ml

2.)The patient takes 12 mg tid.How many whole doses are in the bottle?

Answer :20

Medicine Info:

Medicine total volume is 120 ml.It comes in

10 mg /5 ml

12mg

------- X 5ml

10mg

= 6 ml (amount needed to give a 12mg dose)

if there is 120ml in a bottle

120ml

-------

6ml

= 20 (whole doses available)

Hope this help.

Thank you. @patrickpaters . I figured all of them out last night. I used dimensional analysis for most of them and solved them easily.
