A nurse is reviewing a prescription for ibuprofen 150 mg PO with the parent of a child. Available is ibuprofen suspension 100 mg/5 mL. How many tsp should the nurse advise the parent to administer to the child? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Step-by-step calculation: The desired dose of ibuprofen is 150 mg. The available medication concentration is 100 mg/5 mL. We need to convert mL to tsp. Calculating the volume to administer in mL: Use the concentration of the medication: 150 mg ÷ (100 mg/5 mL) = 150 mg ÷ 20 mg/mL = 7.5 mL Converting mL to tsp: 1 tsp = 5 mL 7.5 mL ÷ 5 mL/tsp = 1.5 tsp
