Understanding volume-osmolality diagrams

Learning objectives
1. Interpret a volume-osmolality diagram, representing alterations in the body fluid status of a patient.
2. Evaluate the impact of five different clinical scenarios on the steady-state plasma volume and osmolality variables in a patient.
3. Apply their knowledge of body fluid concepts to new scenarios on summative assessments.
Key concepts
For health professionals, an understanding of body fluid status is essential to the proper treatment of patients in many clinical situations, and this comprehension is crucial for discussions regarding fluid replacement through intravenous solutions.
Activities
1) Watch the Introductory Video (6-7 min)<
2) List the steps to solve volume osmolality problems
3) Analyze the following clinical cases (#1 - #5)
4) Provide a possible scenario associated with each case
