Question

A nurse is preparing to administer amoxicillin 300mgP0 every 8 hr. Available is amoxicillin oral suspension 250 mg/5 mL. How many mL should the nurse administer per dose?

Answer 1

The nurse should administer 6 mL of the amoxicillin oral suspension per dose to deliver the prescription of amoxicillin 300mg.

Step-by-step explanation:

To calculate the volume of amoxicillin oral suspension the nurse should administer per dose given the prescription of amoxicillin 300mg PO every 8 hours and the available medication strength of 250 mg/5 mL, we use the following steps:

• Determine the amount of medication needed per dose in milligrams (mg).
• Calculate the volume of oral suspension that corresponds to the required dose, using the concentration of the medication.

The prescription requires a dose of 300mg, and the medication is available at a concentration of 250 mg per 5 mL. Hence, we set up a proportion to find the amount of suspension needed:

250 mg : 5 mL = 300 mg : x mL

To solve for x, cross-multiply and divide:

(250 mg) × (x mL) = (300 mg) × (5 mL)

x = (300 mg × 5 mL) / 250 mg

x = 1500 / 250

x = 6 mL

Therefore, the nurse should administer 6 mL of the amoxicillin oral suspension per dose to deliver the required amount of 300mg.
