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 teaspoons? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["1.5"]
7.5 mL is equivalent to 1.5 teaspoons.
To calculate this, use the conversion factor that 1 tsp is equivalent to 5 mL. So, 7.5 mL * (1 tsp / 5 mL) = 1.5 tsp.

Correct Answer is ["1.2"]
Explanation
To calculate this, first convert the adolescent's weight from pounds to kilograms: 96.8 lb * (1 kg / 2.2 lb) =
44 kg.
Then, calculate the dose of ketorolac in mg: 0.4 mg/kg * 44 kg = 17.6 mg.
Finally, divide the dose in mg by the concentration of the ketorolac to find the volume to administer: 17.6 mg / (15 mg/mL) = 1.173 mL, which rounds to 1.2mL when rounded to the nearest tenth.
Correct Answer is ["0.67"]
Explanation
To find out how many mL of risperidone the nurse should administer, we need to set up a proportion.
If 37.5 mg of risperidone is equivalent to 1 mL, then 25 mg of risperidone is equivalent to x mL. The proportion can be writen as 37.5/1 = 25/x. Solving for x, we get x = (25 * 1) / 37.5 = 0.67 mL. The answer is rounded to the nearest hundredth as instructed.
