A nurse is reinforcing teaching with a parent of an infant who has a prescription for amoxicillin 100 mg PO every 3 hr. Available is amoxicillin suspension 200 mg/5 mL. The nurse should tell the parent to administer how many tsp per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Identify the given information: Dose of amoxicillin: 100 mg Concentration of amoxicillin suspension: 200 mg/5 mL Calculate the volume of amoxicillin suspension to be administered: Volume = Dose (mg) / Concentration (mg/mL) Substitute the values: Volume = 100 mg / (200 mg/5 mL) Volume = 2.5 mL Convert the volume to teaspoons: 1 tsp ≈ 4.929 mL Calculate the volume in teaspoons: Volume = 2.5 mL x (1 tsp / 4.929 mL) Volume ≈ 0.5 tsp
