a nurse is preparing a heparin infusion for a client who was hospitalized This is a topic that many people are looking for. bluevelvetrestaurant.com is a channel providing useful information about learning, life, digital marketing and online courses …. it will help you have an overview and solid multi-faceted knowledge . Today, bluevelvetrestaurant.com would like to introduce to you Heparin Drip Calculation Practice Problems for Nurses | Dosage Calculations Nursing. Following along are instructions in the video below:
Is the earth red. Sterner sorry. Ncom.
And in this video. Im going to to work some heparin drip calculations and after you watch this video. You can access free quiz.
At the end of the video that will give you some more practice problems so lets get started the first problem. Says. The md.
Orders your patient to store an iv heparin drip at 12 units per. Kilogram per hour and to administer a loading bolus dose of 60 units per kilogram iv before initiation of the drip your supplied with a heparin bag that reads 25000 units per 250 mls the patient weighs 189 pounds what is the flow rate so the first thing what we want to do is we want to take out the most important information to help us solve our problem and to do that we have to know what the problem wants us to solve for because heparin drip. Calculations will ask you to solve for a wide variety of things this specific problem wants us to figure out the flow rate of this heparin drip.
So were trying to get two milliliters per hour. And when i work dosage and calculation problems if youve watched any of my videos. I do dimensional analysis.
So that is the way we will be working these and well be rounding our answers to the nearest tenth. Always follow what your nursing program wants you to round to or the facility workout. Because it varies okay so were trying to get milliliters per hour.
Now some important information that we got from our problem. Our patients weight heparin is weight based you always want to know a patients weight. They weigh 189 pounds.
We need it in kilograms. So well be converting that we also know that the patient needs to be started at 12 units per. Kilogram per hour.
And we have a bag of heparin on hand every bag of heparin varies in size. So always read it and see what it says it says that in every 250 ml is in that bag theres 25000. Units of heparin.
So lets figure out what were gonna set this pump at 4 milliliters per hour. So the first thing what were going to do is were going to start out with our weight. Remember im using dimensional analysis.
So patient weighs and red and 89 pounds. Okay. Thats our patient.
And we need to get two. Kilograms so we know from the metric. Table theres 22.
Pounds. In one kilogram. So palins cancels up now.
Were ready to plug this in thats what the physician orders the order for the drip to run so for every kilogram that patient weighs. Were going to be giving them 12 units of heparin per hour. So 12 units of heparin per hour kilograms cancels out remember were trying to get milliliters to hour.
Were almost there okay so we have a bag on hand. Bag. Says theres 25000.
Units. In that bag of heparin per. 250.
Mls units. Cancels out the more we left with were left with milliliters per hour. Which is where we are supposed to go so were going to multiply everything in the top everything in the bottom.
And then divide so 189 times 1. Times. 12.
Times. 250 is what 567 thousand and. 22.
Times 1 times. 1. Times 25 thousand is.
55000 and when you divide 567 thousand by. 55000 thats going to give you 1030 9. 09.
Repeating and were going to round to the nearest tenth. So our answer is going to be 10 point three milliliters per hour. That is our answer our next problem says your patient has a heparin drip running at 24 milliliters per.
Hour the heparin bag. Reads 12500 units per 250 mls. How many units per hour is the patient so for this problem.
What are we supposed to figure out we need to figure out how many units per hour. This patient is receiving based on how much is in this bag. And what that flow rate is so we have a bag of heparin.
Hanging and its telling us that in every 250. Mls theres 12500 units of heparin and we have our pump infusing at 24 mls per hour. So how many units are really going in per hour.
So lets set up a problem using dimensional analysis. So well start with the rate that our pump is running so its 24 milliliters is going in over one hour. Remember were trying to get units to our and on hand our.
Bag thats hanging is a 250 ml. Bag and it has 12500 units in it no liters cancels out so were left with units per hour. So were ready to solve multiply everything at the top everything at the.
Bottom and then. Divide so. 24.
Times. 12500. Equals.
300 thousand and 1 times. 250 is 250. Then 300000 divided by 250 equals.
1200 so 1200 units per hour. Is what is infusing on this patient our next problem says your patients recent ptt is 42. According to protocol.
You need to increase the heparin drip by 2 units per kilogram per hour and administer 30 units per kilogram iv bolus. You will recheck the ptt in 6 hours. The patient is currently receiving a heparin drip at 16 units per kilogram per hour from a bag that reads 25000.
Units per 250 mls the patient weighs 163 pounds how many units will the patient receive as a bolus and what will you change the flow rate to this problem. We have a couple things we have to solve for number one we have to figure out how many units. Were gonna give as our bolus.
Then we have to figure out whats our new flow rate. Going to be because theyre ptt came back where its not therapeutic. So weve got to adjust that heparin drip.
So we can hopefully on the next blood draw get their ptt within range so looking at that problem. Whats the important information. We need to glean okay.
Number. One our protocol. Tells us because their ptt wasnt therapeutic.
Then were gonna have to increase the drip by two units per kilogram per hour. It also tells us that because their ptt wasnt therapeutic that theyre going to get a 30 unit. Bolus per kilogram.
So every kilogram that patient weighs. Theyre going to get 30 units. Their current pump right now.
The pump is currently running at 16 units per kilogram per hour. But we want to increase that and why are we gonna increase that by two units so lets just go ahead and put that there so we wont forget so. 16 plus.
2. Is 18. So were we wanting to get is 18 units per kilogram per hour.
Thats the new dosage that they need now what we have we have on. Hand a heparin bag that reads for every 250. Mls theres 25000.
Units. And our patient weighs 163 pounds. So lets do the easiest part first lets figure out how many units.
Were gonna give them as their bolus heparin is weight based. So we need to figure out there waiting kilograms so 163 pounds is how much our patient. Weighs we know from the metric.
Table that theres 22. Pounds. And 1 kilogram.
So go ahead. Solve that 1 times. 1.
Is 1 63. 1 times 2 point. 2.
Is 2 point. 2. So 163 divided by 2 point.
2 equals seventy four point zero nine zero nine repeating and were going to round to the nearest. Tenth so 70 41. Kilograms is how much our patient weighs.
So for every kilogram that patient weighs. They need 30 units of heparin for a. Bolus so were just going to multiply that by 30 and 70 41.
Times. 30 equals. Two thousand two hundred and twenty three units.
So that is how much of a bolus theyre going to get now. Lets figure out our new flow rate. Okay patient now because were increasing it from 16 to 18.
Because they need two extra units. So were going to start with our. Weight so 163.
Pounds. Number one theres 22. Pounds.
And 1 kilogram and our new order is for every kilogram patient weighs. The doctor wants them to have 18 units per hour. So 18 units hour and pee on the kilogram all that had cancel out now on.
Hand we have this. Bag so 25000. Units.
Equals. 250. Mls units count cancels out.
And we need to get 2. Milliliters per hour. So were ready to solve so multiply everything at the top and the bottom and divide.
So. 160 3 times. 1.
Times. 18 times. 250 equals.
730 3501 times two point 2 times 1 times 25 thousand equals. 55000 then well divide that 733 thousand five hundred divided by 55000. Equals.
Thirteen point three three six three six three repeating and well round to the nearest tenth. So thirteen point three liters per hour is our new flow rate okay so that wraps up this review over heparin drip calculations.
