The physician's order is for Lactulose 2 tsp. by mouth at bedtime. How much would you give using the metric system?

To convert teaspoons to milliliters using the metric system, it's important to know that one teaspoon is approximately equal to 5 milliliters. Therefore, to find out how many milliliters are in 2 teaspoons, you multiply the number of teaspoons by the conversion factor:

2 tsp x 5 ml/tsp = 10 ml.

This conversion is essential for accurate dosing of medication, as it ensures that the patient receives the correct amount as prescribed by the physician. Choosing 10 ml demonstrates a proper understanding of unit conversion in pharmacology, maintaining patient safety and compliance with medical orders.
