hyponatraemia occurs when serum sodium levels drop too much. Why do you think drinking deionized water would result in low blood sodium levels?
1. hyponatraemia occurs when serum sodium levels drop too much. Why do you think drinking
deionized water would result in low blood sodium levels? (Think about solute diffusion)
2. Think back to the concepts we learned in lecture. Explain why low serum sodium levels
would cause water to move into brain cells.
3. According to the article, was the individual's excessive water intake related to physiological
or psychological symptoms? Explain your reasoning
4. What could have the individual added to her water to prevent this from happening, and why
would this have prevented hyponatraemia? Incorporate your knowledge of concentration
gradients and diffusion.
5. Over-hydration can be treated if caught in its early stages. What do you think would be the
quickest way to restore the patient's serum sodium levels?
