Which statement correctly matches isotonic, hypotonic, and hypertonic IV solutions with examples?

• A. Isotonic (0.9% NS) has same osmolality as plasma; Hypotonic (0.45% NS) lower osmolality; Hypertonic (3% NS) higher osmolality.
• B. Isotonic (3% NS) has same osmolality as plasma; Hypotonic (0.9% NS) lower; Hypertonic (0.45% NS) higher.
• C. Isotonic (D5W) has same osmolality as plasma; Hypotonic (5% Dextrose) lower; Hypertonic (0.9% NS) higher.
• D. Isotonic (0.45% NS) has same osmolality as plasma; Hypotonic (0.9% NS) lower; Hypertonic (3% NS) higher.

Answer: (A)
