Patient Background: Maria, a 45-year-old female, presents to the emergency room with symptoms of severe dehydration following prolonged vomiting and diarrhea. Her lab results indicate the following:
- Serum sodium: Elevated (hypernatremia)
- Urine output: Low
- Heart rate: Elevated (tachycardia)
- Blood pressure: Low (hypotension)
The attending physician has ordered an IV to address Maria’s dehydration and stabilize her condition. Three IV solutions are available for consideration:
- 0.45% saline (hypotonic)
- 0.9% saline (isotonic)
- 3% saline (hypertonic)
Your task is to analyze the situation, considering how each IV solution would interact with Maria’s cells and overall condition, and recommend the best choice.
