Today, star-trek-voyager.net would like to introduce to you Tube Feeding Nursing Calculations Problems Dilution Enteral (PEG and Nasogastric NG). Following along are instructions in the video below:
Everyone its sarah with registerednessrncom. And in this video. I want to go over over how to solve tube feeding calculations and as always whenever you get done watching youtube video you can access the free quiz that will give you more practice on these calculations.
So lets get started in this calculations video. Were going to solve different types of two feeding problems you may encounter on your exam. So im going to walk you step by step how to solve problems that require you to figure out how much water is needed to dilute the feeding formula along with how to calculate that total volume that youre going to have to administer to the patient.
And how much time it will take for that tube feeding to be administered. Now as i do that were going to be using a specific formula to help us do that plus. Im going to be using some dimensional analysis to help us solve for some of these answers so if youre not familiar with dimensional analysis.
I really recommend that you check out the other videos in this dosage and calculation series. So what is a tube feeding well. Its just as the name says.
Its a tube that is going to deliver nutrition to your patient because they need some help getting some nutrition and this can be done various ways one way is through a nasogastric tube hence we call it nasal because its going to go up through the nose and a type of nasogastric tube is like a dobhoff tube. So it goes up through the nose down through the throat. And then it sets in the stomach and we can deliver formula to that patient also it can be administered through a peg tube.
And this is a tube. Where a surgical incision has been made through the skin and a tube enters in to the stomach through that route so to help us solve some of these problems. We need to remember this certain formula.
So i really recommend you commit this formula to memory. And how you set it up. It will be milliliters in the formula can over x equals.
The strength ordered so now lets look at our first. Problem and it says the patient is order. Jeopardy.
12. Cow. Youre supplied with a can of jelly that contains 237 milliliters of formula.
The doctor orders the tube feeding to be administered at half strength at a rate of 60 milliliters per hour. What is the total volume of formula that will be administered so the very first thing. What you want to do is you want to look at what the problem is asking you and this problem is specifically asking for the total volume of formula that will be administered.
So you need to look in your problems. See what you need to pull out of that problem to do your calculation. And remember a lot of problems are going to give you information that you really dont need theyre called distractors.
So whats important in this scenario is the amount of formula thats in that jvt can which is 237 milliliters and the strength that the doctor has ordered were not really concerned about the 60 milliliters per hour to help us calculate that total volume formula so thats really our distractor so since we already know what were solving for and the information we need to solve that were ready to use that formula so were going to set our formula up with milliliters in the can it told us that there was 237 milliliters in that can of gevity and were going to put that over x and then we have the strength and it told us. It was half a string. So were going to put that like that now we are ready to solve so to solve were going to multiply everything across from each other so 237 times.
2. Is 474. So we have milliliters and x times.
1. Is 1x now we have to finish solving so we need to get rid of this one because were solving for x. So were going to divide by one that cancels out one.
Were going to also do that over here on this side and then whenever we calculate that out we get 474 milliliters equals x. And this is our total volume. So 474 milliliters is the total volume thats going to be administered to this patient.
Now lets look at our next. Problem it says the patient is order gevity 12. Cow.
Youre supplied with a can of gevity that contains 237 milliliters of formula. The doctor orders the tube feeding to be administered at half strength at a rate of 60 milliliters per hour. How much water will you add to dilute the tube feeding formula as prescribed so this problem is wanting to know how much water.
Were going to add to that tube feeding formula to meet the specifications that the doctor has ordered so that is very important to know now what other information do we need to know in this scenario to help us solve for that well we need to know how much this can contains in it which it contains 237 milliliters and what the ordered strength is which is half strength so since we already know what were solving for were ready to set up our formulas. So were going to use this formula our can contains 237 milliliters and were solving for x. And were going to put the strength over here.
Its half strength. So were going to multiply everything across from each other so 237 times. 2.
Is 474. So we get 474 milliliters and then x times. One is one x now we need to get rid of that one so were gonna divide everything what we do on this side.
We have to do over here so whenever you solve that out you get 474 milliliters equals x. Now this is the total volume.

But our problem is not asking for the total volume. We need to know the amount of water well how were going to do that how were going to figure that out well since we already know that our can contains 237 mls. We know that our total volume is going to be 474 ml.
So what were going to do is were going to subtract 474 from the from the volume in the can so. Its 237. So 474 minus 237 equals.
237. Ml and this is milliliters of water. Thats going to be added to that for that feeding formula to dilute.
It based on what the physician ordered now lets look at our. Next. Problem it.
Says the patient is ordered. Glucerno. 15.
Cal. Youre supplied with a can of glucerna that contains 237 mls of formula. The doctor orders the tube feeding to be administered at 1 4.
Strength at a rate of 50 mls per hour. How much water will you add to dilute the tube feeding formula as prescribed so again we need to ask ourselves what are we solving for well this problem wants to know how much water. Were going to add to that feeding formula to dilute it so what important information do we need to pull out of this scenario well we need to know how much is in a can of glucerna that were supplied with and its 237 mls and we need to know that strength and its 1 4.
Strength. Now a distractor is that rate of 50 mls per hour. Were not really concerned with that its important.
But its not what we need to solve this problem so we pulled from that scenario. What we need to solve this problem. So now were ready to plug into our formula.
So were going to put how much milliliters was in that glucernican and it told us. There was 237 milliliters and were solving for x. Because remember that helps us solve for our total volume.
And then we have this strength and the strength is 1 4. So lets figure out our total volume. Then once we figure out total volume.
We can subtract that amount from how much is originally in this can and then we get the amount of water. We need so were going to multiply everything across from each other so 237 times. 4.
Is 948. So we get 948 milliliters and then x times. 1.
Equals. 1x and then we need to get rid of that one so were going to divide everything that cancels that out over there leaving us just with x. Then we what we did over here on this side.
We got to do over here. So when you work that out and divide that you get 948 mls equals x. Which is our total volume.
But our question doesnt want to know total volume and wants to know the amount of water. We need to dilute this feeding formula. So were going to take 948 and subtract it from 237 milliliters and we get 711 milliliters of water that were going to need to dilute this tube feeding formula to meet the parameters that the physician has given us now lets look at our next problem.
It says the md orders glucerna via the patients nasogastric tube. The formula is to be administered at 3 4. Strength at a rate of 60 ml per hour.
Youre supplied with a can of glucerna that contains 237 mls. How long will it take to administer this tube feeding formula. So this problem wants to know how long its going to take to administer this specific tube feeding formula.
So first what were going to have to do is calculate the total volume. And again the total volume is the amount that is in that two feeding formula can plus. If we have to dilute it with water.
So thats our total volume. So we need to know what were supplied with so the can of glucerna and it tells us its a 237 ml cam. And then we need to know the strength of how this two feeding is going to be administered.
So we need to do a three fourth string. So those two things are very important now when we solve for that were going to have to go and were going to have to look at the rate.

How this physician wants this to be administered to this patient. And it tells us that we need to give it at a rate of 60 mls per hour. So based on everything we pulled out of that scenario.
We know that this is going to be a two step problem because first we have to solve for that total volume. And this is where this formula is going to come in handy. Then were going to take that answer and then were going to apply it to the rate and see how long its going to take to administer that amount based on this rate.
The physician ordered so lets start with our formula first so milliliters and can it was 237 milliliters and were solving for the total volume. So thats over x. And the strength is three fourths.
So were going to put that over here and were going to multiply everything across from each other so 237 times. 4. Is 940 milliliters and then x times.
3. Is 3x now weve got to get rid of that. 3.
Because we want to solve for x. So were going to divide that cancels that out what we did over here. We have to do over here so 948 divided by 3.
Is 316 ml and that equals our total volume. So thats the total amount thats going to be given to that patient that includes um. The formula amount thats in that can plus that water.
We added to it to equal that 3 4. Strength. Now lets solve for infusion time so.
What were going to do is were going to take our total volume. And this is where were setting up with like dimensional analysis. So were going to do 3 16.
Ml over 1 times our rate. Thats where our rate comes in handy. So its 60 ml.
So. 60. Mls per hour.
Okay. Mls cancels out figuring out our time. So 316 times.
1. Is 316 and then 1 times 60 is. 60 so 316 divided by 60 is 52666.
Repeating and i want to round to 527. Always round how your program wants you to. Round so this tells us that we have 527.
Hours. Well weve got to take that a step further we know its going to take us 5. Hours but this 027 is in hours.
We need to really convert this to minutes. So im going to go ahead and write five hours right here. I need to convert this leftover hours to.
Minutes lets figure that out so were going to take 027. Because thats our leftover from the hours. And thats hours over 1 times.
We know that 1 hour. Equals 60 minutes. So were converting that to minutes hours cancels out and 27 times.
60 is 162 minutes. So were going to round to our nearest whole number. So its going to be 16 minutes.
So our answer is that its going to take 5 hours and 16 minutes to infuse this total volume based on this rate. That the physician ordered okay. So that wraps up this video on how to solve for tube feeding calculations and dont forget to access the free quiz.
That will give you more practice and to check out the other videos in this dosage and calculation series. .
