A nurse is preparing to administer 7.5 mL of ampicillin 250 mg oral suspension to a toddler who has otitis media. The nurse should recognize that 7.5 mL is equivalent to how many tsp? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Step-by-step calculation: Convert to milliliters (mL) to teaspoons (tsp). The conversion factor is: 1 teaspoon (tsp) = 5 milliliters (mL) Performing the calculation: Divide the given milliliters by the conversion factor: 7.5 mL ÷ 5 mL/tsp = 1.5 tsp Rounding the answer: 1.5 is already rounded to the nearest tenth.
