We value your time, which is why we made lab values easier than ever to understand with Picmonic’s learning pathway for acid-base imbalances!
How do I learn and remember the Acid-Base imbalances as a Nursing Student?
Picmonic has a super-easy nursing acid-base imbalances visual study guide that will help you soak in all the acid-base information you need in a way that you will never forget. We worked hard to make sure this study aid is simple to understand and fun, utilizing the concept of picture-mnemonics and memory palaces, ie turning it into a memorable Picmonic.
First, watch this Picmonic on How To Interpret Acid Base Disorders, it’s under 5-minutes and we promise you’ll be impressed!
Second, read this article to learn the basics of how to interpret acid-base imbalances in 3 steps.
Third, test your knowledge afterward with this FREE QUIZ!
Did you already learn the Picmonic? Make sure you do BEFORE reading below ;)
Now, watch Dr. Kendall Wyatt, MD, RN, EMTP, teach the basics of how to interpret Acid-Base Imbalances.

Helpful Hint: Look at the numbers .35 and .45 in the pH levels. Looks pretty similar to the lab values of 35-45 in pCO2, right? You’ve already got two lab values memorized right there!
Once you’ve got those lab values memorized, it’s easy to recognize what is abnormal. Now, if a patient’s pH falls below 7.35, they are in a state of acidosis (remember the acidic-lemon?). If the patient’s pH is above 7.45, the patient would be in a state of alkalosis (the elk-looser).
2. Figure out what kind of acidosis or alkalosis our patient is in: respiratory or metabolic?
A good little trick here is to look at the pH and see what direction it’s going (up or down), and then look at the CO2 and see what direction that’s going. If they are going in the opposite directions, then we have ourselves a patient with a respiratory disorder.
That’s where you take part one (acidosis or alkalosis) and match it here with respiratory (respiratory acidosis or respiratory alkalosis), and voila! You’ve solved yourself an acid-base problem, my friend. There’s more information about this in Picmonic’s colorful nursing acid-base imbalances illustrated study aid, but these are the basics.
Now, if you’re saying, “Wait, the pH and the pCO2 are not going in opposite directions!” Then have no fear, you move on to step three.
Step three is to check the bicarbonate (HCO3) level. The normal range for HCO3 levels is 22-26 mmHg, and this is regulated by the kidneys. Because of this, it is slow to react and can take up to 24 hours to begin compensating, whereas the respiratory system can respond in minutes.
If the HCO3 is going in the same direction as the pH, then we most likely have ourselves a metabolic problem.
How do we know which disorder it is?
You can deep dive into this topic with Picmonic’s nursing acid-base imbalances online study guide, but we also have another little trick: if the patient is in a state of metabolic acidosis, then everything is going down, down, down. This means decreased pH, decreased pCO2 and decreased HCO3.
On the contrary, if the patient is in a state of metabolic alkalosis, then everything is going up, up, up. That means increased pH, increased pCO2, increased HCO3. It’s a cinch, right?
We hope so. If this is still tricky for you, be sure to check out our comprehensive nursing acid-base imbalances online study guide. It’s a visual mnemonics study aid that will help you retain 331% more knowledge than simply reading a textbook. (yes, 331% is per an IRB approved study published in PubMed)
If you’re already a whiz and are asking yourself about compensation mechanisms then you’ll have no problem adding those concepts right onto this fundamental base of knowledge. And if you’re not totally sure what compensation mechanisms are, may we introduce you to our nursing acid-base imbalances visual study guide? It’s super helpful and will get you up-to-speed in no time so you’ll really get those concepts burned into your brain! But like, burned in a good way.
Although side-note, when you’re done fully understanding how to Interpret Acid Base Disorders, with a Picmonic Free account you can start learning the 8 more detailed Picmonic’s on acid-base imbalances! After learning these Picmonics in less than an hour, test your knowledge!
YOU WILL NEVER MISS ANOTHER ACID-BASE TEST QUESTION!!!
After that, there’s a whole nursing burns visual study aid too, if/when you need it. ;)
