What does the ISR Rule of Tens specify for fluid resuscitation rate?

• A. BSA x 5 cc/hour
• B. BSA x 10 cc/hour
• C. Body Weight x 10 cc/hour
• D. BSA Divided by 10 cc/hour

Answer: (B)

The main idea is to use body size to set a steady, predictable fluid resuscitation rate. The ISR Rule of Tens uses body surface area to determine how fast to infuse fluids: you take the patient’s BSA (in square meters) and multiply by 10 to get the infusion rate in milliliters per hour. For example, a patient with a BSA around 1.9 m² would receive about 19 cc per hour, with adjustments made based on perfusion, ongoing bleeding, and clinical signs. This approach differs from weight-based rates or other formulas because it bases the rate on surface area, not body weight or a divided/inverted factor. So options using body weight, or multiplying by a different factor, or dividing by 10, don’t fit the rule.
