Course Overview

Hyponatremia Explained Clearly is a course designed to clarify, review, and augment the training and understanding of primary care clinicians in the treatment of hyponatremia. The modules included in this course take a departure from the traditional slide presentation style lecture. Instead, the course is comprised of a series of video lectures aided by real-time instructor-led chalkboard visuals. This method of learning allows for the subject matter to be broken down to the basics and is designed to increase learning and retention. 


Hyponatremia is an important and common clinical problem. Because there are multiple causes for hyponatremia, it is imperative for clinicians to understand how to properly interpret the various laboratory tests and differentiate the various types of hyponatremia. Many clinicians lack training, understanding, and skill in the diagnosis and treatment of various types of hyponatremia. This CME course will utilize a combination of videos, quizzes, and systematic discussion of clinical scenarios and practice cases to effectively deliver the course content. 

Course Objectives:

As a result of this educational activity, participants should be better able to:

  • Effectively identify the different types of hyponatremia and their causes.   
  • Test if the kidneys are the cause or if they are involved in the correction of different types of hyponatremia. 
  • Correctly identify the body compartments that distribute sodium and water and their involvement in the management of hyponatremia.   

Post-Test and Evaluation:

After completing the CME activity, you must successfully complete a post-test and fill out a program evaluation form. You will then be able to view and print your CME certificate.

    I loved this review. The visuals help me to understand the pathophysiology and keep things straight in my head.

    MARY BUTCHER, Pharmacist

    Explaining a complex topic this clearly helped me better understand hyponatremia. The diagrams using different colors were very helpful. To be honest I was struggling to visualize the different aspects of the condition. My purpose of studying this particular topic is preparation for Board Certification in Pharmacotherapy. No other presentation is so succinct and clear. Thanks.
