A nurse is preparing to administer 5 mL of digoxin elixir PO to a toddler. The nurse should recognize that this is equivalent to how many tsp? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

The conversion of milliliters to teaspoons is a common calculation in medical dosing. For the administration of 5 mL of digoxin elixir PO, the equivalent in teaspoons would be approximately 1.01442 teaspoons. When rounding to the nearest whole number, as per medical dosing guidelines which often require precise measurements to ensure safety, the amount would be 1 teaspoon. It's important to use a leading zero if it applies to indicate less than one, and not to use a trailing zero as it could be mistaken for a larger dose. Therefore, the nurse should recognize that 5 mL is equivalent to 1 teaspoon.
