In this NursingSOS video, Christina Rafano walks nursing students through the essential interventions for a patient with diabetic ketoacidosis (DKA) and highlights the NCLEX‑style critical‑thinking points that are likely to appear on exams. She begins with a concise pathophysiology refresher, using the metaphor of insulin as a key that unlocks cells for glucose, and explains how insulin deficiency forces the body to burn fat, producing acidic ketones. The core of the lecture covers three intervention pillars: (1) fluid resuscitation – selecting normal saline or lactated Ringer’s first (isotonic), then half‑normal saline to hydrate cells, and adding 5‑10 % dextrose in half‑normal saline once glucose falls to 250‑300 mg/dL; (2) insulin therapy – regular IV insulin to restore glucose uptake while continuously monitoring blood glucose to avoid a rapid drop; (3) vigilant monitoring for cerebral edema, including changes in consciousness, headache, hypertension, bradycardia, widened pulse pressure, and irregular respirations. Rafano stresses the importance of ongoing assessments: intake‑output, urine ketones, weight, respiratory status, IV site, fluid status, blood glucose, ABG values, electrolytes (K⁺, Na⁺), and mental status. Throughout, she ties each step to NCLEX‑style critical‑thinking questions, urging students to apply concepts rather than memorize facts. The video also includes brief promotional mentions of free study guides and additional resources.

Hey there my friend. My name is Christina Rafano from nursingsos.com and in this video today we are walking through the nursing interventions that you might do for a patient with diabetic ketoacidosis, or DKA for short. I'll also walk you through the key nclex points that are most likely to show up on your nursing school exam, so you will be a lot more prepared. So hit that subscribe button and click the notification bell and let's dive in. Now real quick, I want to make sure that you know about my free study guide pack that I have for you, which is going to help you so much in med Surg. Study guides are an awesome tool to use to help you learn things faster and I have a whole pack of 10 of them that I want to send to you. I will put the link to these down below in the description, so be sure to check that out after you watch this video. Now, DKA occurs when there is not enough insulin in the body, and insulin is required to help move glucose into the cells. I like to think of insulin as a key that unlocks the body cells and lets glucose in. So when you think of insulin, think of it as a key. Glucose is the cell's best source of energy, but in diabetes, the pancreas isn't making insulin anymore or the cells are resistant to it. So without insulin, the cells can't get any glucose. And because the cells don't have insulin, they start converting fat into energy instead. And this fat breakdown leads to ketones building up in the blood, which are acids. So here's how I like to think about this. Without the insulin key, right? The body uses fat and the key tones. So both insulin and fats are keys. But insulin is definitely better than fat and the key tones. And you'll see why in a minute. But that's just a nice memory trick to help you remember that. Now, if you want a breakdown of the pathophysiology of dka, definitely check out this video here. Okay, so there are a few nursing interventions you'll need to focus on in a patient with dka. Let's walk through them. The first one is fluid treatment, and I know IV fluids can be so confusing, so we'll also walk through the critical thinking behind it all for you to make it easier to understand. And of course, you will also be way more prepared for your nursing school exams. Right, because critical thinking is everything. Your exams are all about critical thinking. So we're going to walk through it all right here. So giving fluids is One of two main treatments that you'll do with a patient with dka, the goal here is to reduce the blood glucose level and keep the organs perfused. For dka, you'll typically give normal saline, lactated ringers, half normal saline, or 5 to 10% dextrose and half normal saline. So here's a fun memory trick for you. If glucose is high, we need to drop it. Isotonic, hypotonic and dextrose. If it's high, drop it. All of these fluids serve different purposes, so let's walk through that. Normal saline or lactated ringers is usually given first. Now, here's your key critical thinking point for this. Isotonic solutions are given first because they are not going to force fluid any which way. Those solutions are going to stay inside the blood vessels, which is where we want them. And then half normal saline may be used after normal saline or lactated ringers in order to hydrate the cells. Because half normal saline will push some fluid inside the cells rather than just staying outside the cel. Normal saline or lactated ringers do. You may also give 5 to 10% dextrose in half normal saline as the blood glucose level starts to drop to around 250 to 300 milligrams per deciliter. Now, this can be confusing. Why would we give glucose when we're trying to drop the patient's blood glucose level? Here's another big critical thinking point for you. This is really, really, really important because we don't want to drop it too much. We want to control the blood gluc by giving some more glucose and controlling the rate that it decreases. If we just give normal fluids without glucose plus insulin, that insulin could drop the blood glucose level way too fast. So when the blood glucose level reaches that level between 250 to 300 milligrams per deciliter, you will want to give glucose along with the fluids, depending on the doctor's orders. Now, let's talk about insulin treatment. So we know that the core problem in DKA is a lack of insulin. So we need to give insulin to help the cells take up that glucose for energy so they can stop using fat for energy and producing those acidic ketones, right? So depending on the doctor's orders, you might give regular insulin through the IV to help move that glucose into the body cells. And then you will need to be constantly assessing their blood glucose level during treatment because you don't want to drop that blood sugar too fast. And here's why this is really important. The body is always wanting to. So if you drop the blood glucose level too fast, the water in the body will try to rebalance itself and move from the intracellular fluid, the icf, to the extracellular fluid called the ecf. And if this happens too fast, fluid will move into the cerebral spinal fluid to try to maintain that balance and this can lead to swelling in the brain. This is called cerebral edema and can cause increased intracranial pressure. Big problem. This is bad news. Increased intracranial pressure is a medical emergency, so look for changes in their level of consciousness, headache, increased blood pressure, decrease in heart rate, widening pulse pressure and irregular respirations. This is super dangerous and causes even more of a medical emergency here. So it's really important that you always assess your patient and be very careful when giving insulin and fluid treatment. I have a whole video series plus a whole study guide on increased intracranial pressure for you inside the nursing SOS membership community and I'll put the link to that down below if you are interested. And of course you will need to continually assess your patient by checking their intake and output, their urine ketones, their weight, and monitoring their respirations. You'll assess their iv, assess their fluid and their fluid status. Make sure the correct fluids are infusing like they should be. Make sure to check their blood glucose level levels, their urine ketones, their ABG values, and their potassium and their sodium levels. You will also consistently assess their mental status to clue you in on any increased intracranial pressure. Now, the key thing to know about med surge in nursing school is that it is not about memorizing things, right? Your exams, they're going to focus so heavily on critical thinking and how well you apply what you know to an exam question. So in this next video, I am walking you through the pathophysiology of DKA so that you'll be able to critically think about it better on your nursing exams.
