Explanation
Identify the given information:
Dose of methylphenidate: 10 mg
Concentration of methylphenidate oral solution: 5 mg/tsp
Calculate the volume of methylphenidate to be administered:
Volume = Dose (mg) / Concentration (mg/tsp)
Substitute the values:
Volume = 10 mg / 5 mg/tsp
Calculate the result:
Volume = 2 tsp
Convert tsp to mL:
1 tsp ≈ 4.929 mL
Calculate the volume in mL:
Volume = 2 tsp x 4.929 mL/tsp
Calculate the result:
Volume ≈ 9.858 mL
Round the answer to the nearest whole number:
Volume ≈ 10 mL
