Mastering IV Flow Rate Calculations for Safe Patient Care

Sarah, a registered nurse, explains how to calculate IV flow rates using a specific formula. The video covers solving dosage calculations for drops per minute, emphasizing the importance of converting units and understanding the drop factor. Several example problems are solved, demonstrating the application of the formula in different scenarios, including conversions from liters to milliliters and calculating hourly rates.
