A pаtient is brоught tо the emergency rоom аfter collаpsing during a long, hot hike. The patient is dehydrated, with symptoms including dizziness, low blood pressure, and dry skin. The nurse must choose one of the following IV solutions to help restore the body’s fluid balance: 0.9% NaCl (Normal Saline) – Isotonic 0.45% NaCl (½ Normal Saline) – Hypotonic 3% NaCl – Hypertonic Based on this information and what you've learned about osmosis, tonicity, and the movement of water across cell membranes, answer the following questions: Predict how red blood cells would respond if a patient were given each of the following IV solutions: 0.9% NaCl (isotonic), 0.45% NaCl (hypotonic), and 3% NaCl (hypertonic).In your answer, include the direction of water movement across red blood cell membranes and describe how the cells would respond in each case. Which IV solution would be the safest and most effective for this patient? Explain your reasoning based on osmosis and tonicity. Why is understanding tonicity and IV fluid selection important for anyone entering a healthcare or medical field? Your answer should be a paragraph of at least 4–5 sentences and address all parts of the question.
