Acute Kidney Injury (Acute Renal Failure) Nursing NCLEX Review Management, Stages, Pathophysiology

  • Published on Jul 15, 2017
  • Acute kidney injury (also called acute renal failure) nursing NCLEX review lecture on the nursing management, stages, pathophysiology, and causes (prerenal, intrarenal, postrenal).
    What is Acute Kidney Injury? It is the SUDDEN decrease in renal function that leads to the build up of waste in the blood, fluid overload, and electrolyte imbalances.
    What are the causes of Acute Kidney Injury? There are three causes, which are based on location. The first is known as prerenal injury and this is an issue with the perfusion to the kidneys that leads to decreased renal function. A second cause is known as intrarenal injury, and this is due to damage to the nephrons of the kidney. Lastly, postrenal injury is due to a blockage located in the urinary tract after the kidney that can extend to the urethra. This is causing the back flow of urine, which increases the pressure and waste in the kidneys.
    Stages of Acute Kidney Injury: There are four stage of acute kidney injury, which include initiation, oliguric, diuresis, and recovery stage. The initiation stage starts when a cause creates an injury to the kidney and then signs and symptoms start to appear. This leads to the oliguric stages. The patient will void less than 400 mL/day of urine during this stage and will experience increased BUN/creatinine levels, azotemia, hyperkalemia, hypervolemia, increase phosphate and decreased calcium levels along with metabolic acidosis.
    After this stage the patient can progress to the diuresis stage and this is where the patient will void 3-6 Liters of urine per day due to osmotic diuresis. The patient is at risk for hypokalemia, dehydration, and hypovolemia. The last stage is recovery and the patient's glomerular filtration rate has returned to normal. Therefore, the kidneys are able to maintain normal BUN and creatinine levels, electrolyte, and water levels.

    Hi Sarah! 🙂
    I just want to say thank you for making these informative videos. You made them in a way that we can easily grasp the content. I'm an international nurse and I passed my NCLEX on my first attempt last May 2019 with 75 questions. And you have a big contribution to my success.
    I hope and pray that you will continue to help a lot of nurses/future nurses.
    God bless 🙏

    Back again, 4 weeks left til I finish my RN degree and that is very much thanks to your videos! They have got me thru every test, so thankful I discovered this site back in my first semester. I'll be graduating with highest honors, have maintained a 4.0 GPA all thru the program! And received several scholarships and offers because of it. So seriously THANK YOU for all you do to help us nursing students! I feel completely confident about the NCLEX and that is also thanks to your videos. Can't wait to graduate in 4 weeks! We have one more test on this (renal) and burns which I have been watching those videos too, then the final, and 2 more clinicals and I'm done! I will be returning to your videos when I go back for my BSN next, then masters for nurse midwife! Feels great to be checking off goals!

    absolutely brilliant presentation. My father (90 yr old and ill) developed AKI and this has helped me understand the realistic prognosis for him. He's not in End stage renal failure which is regrettable but understanding the mechanism and S&S's etc has really helped when discussing with his doctors what is the most appropriate treatment plan. many thanks x

    try raisins, and try adding raisins to your water. take N-Acetyl-Cysteine and Glutathione. Vitamin C and vitamin K2 also help... I was really suffering yesturday but this combination of vitamins and minerals have really helped... remember you need to look after yourself for 3yrs plus to have a permanent improvement in your liver and kidney function... imo anyway

    Hi Sarah, I just want to say I have been reading from multiple sources, answering NCLEX questions, and going over class powerpoints for hours on end. Of all the studying I’ve done, your videos helped me the most and made the most sense because you explain it much more efficiently and effectively. My stress levels went from beyond 10 to a 3 in 30 minutes thanks to you. Thank you so much for your website and your nursing videos!!!!
