If the prescribed dosage is doubled to 20 mcg per min, would you expect the infusion pump setting to double (set at 6 mL per hr)? Yes or No? 2. The nurse increased a lidocaine infusion of 2 g in 250 mL D5W to 30 mL per hr to control the patient's dysrhythmia. You should document that the patient is now receiving \_\_\_\_\_\_ mg per min. 3. The physician prescribes dopamine 400 mg in 250 mL D5W to start at 5 mcg/kg/min for a patient weighing 178 lb. You should set the infusion pump at \_\_\_\_\_\_ mL per hr.

00:02 So we are told we have a 50 milliliter vial that contains a drug and the concentration is in milligrams per milliliter.

00:14 It is added to 100 milliliters of water and it will be distributed through an iv.

00:25 The iv is set up to deliver 15 drops per millimeter and we need to know how many drops.

00:36 How many drops per minute to deliver 25 milligrams of the drug per hour.

00:56 So the first step of this problem is to combine these two values.

01:02 So we have 15 milliliters plus 100 millimeters equals 150 millimeters.

01:14 And in this 150 milliliters, we know that the drug contains 1 ,000, milligram per milliliter.

01:25 Since we were given 50 milliliters of the drug initially, we know that there are 50 milligrams per 150 milliliters.

01:40 So we can reduce this down, divide by 50, and we'll get one milligram per three milliliters.

01:51 Now let's work with this value here.

01:54 We have 25 milligrams of the drug per hour.

02:00 We need to get to drops per minute.

02:03 So let's convert this hours to minutes.

02:07 So we have one hour equals 60 minutes.

02:14 And this gets rid of our hours and we're left with a minute.

02:17 So we're left with milligrams over minutes.

02:21 Now we have to get to drops.

02:23 Well, we know the iv gives 15 drops per milliliter and we know that the drug is in one milligram per three milliliters.

02:34 So to get rid of the milligrams we're going to use this conversion right here.

02:40 So for every one milligram, you're going to have to deliver three milliliters of the solution.

02:47 Now we are, so milligrams cancels out.

02:50 Now we are in milliliters per minute, but we know that there are 15 drops per milliliter.

02:58 So for every one milliliter, we're going to need 15 drops.

03:05 Milliliters cancels out and we're left with drops per minute.

03:11 So let's do that now...
