Electrolytes Made Easy: Hyponatremia & Hypernatremia Explained for Nursing Students

Electrolytes 101 – How to Spot Life-Threatening Imbalances

Electrolytes aren’t just numbers on a lab report—they can be the difference between life and death. In this episode of Nursing School Week by Week, we’re breaking down sodium imbalances in a way that actually makes sense.

Imagine this: You’re a brand-new nurse, juggling a million tasks, and your preceptor tells you your patient is acting confused. What’s your next move? Could it be low oxygen? Low blood sugar? Or an electrolyte imbalance?

Today, we’re tackling hyponatremia and hypernatremia, two conditions that can wreak havoc on the brain and body. You’ll learn:
✅ Why sodium is the “brain’s best friend” and what happens when levels drop too low or climb too high
✅ The telltale signs of sodium imbalances—from confusion and seizures to extreme thirst and restlessness
✅ Real-world nursing scenarios to help you recognize electrolyte imbalances FAST
✅ Key interventions you need to know to keep your patients safe

Plus, we’ll quiz you along the way to help lock in the knowledge for exams and the NCLEX!

Hit play now to boost your electrolyte knowledge, and don’t forget to tune in next week for Part 2, where we’ll break down potassium imbalances—the ones that can throw your patient’s heart into a deadly rhythm! 🚑💉
