Revising the 4 major electrolytes in the body that are essential to maintaining homeostasis and revising the implications of electrolyte imbalances and know how to manage these has built my confidence when reviewing my client. In my field of Drug and and Alcohol nursing we are often taking ECG's and looking at blood test results of clients who are often malnourished and may have multiple medical problems.
