Dosage Calculations ( 10 Questions)
A client has been prescribed an oral suspension with a concentration of 250 mg/5mL. The prescribed dose for the client’s weight and condition is 750 mg. How many teaspoons (tsp)of suspension should be administered?
To calculate the volume of liquid medication to administer based on its concentration and prescribed dose, the nurse should divide the prescribed dose by concentration and multiply by the volume in which concentration is expressed. In this case, the concentration is 250 mg/5mL and the prescribed dose is 750 mg so, the nurse should administer(750mg/250mg)x5mL=15mL of medication. Since 1 tsp is equivalent to 5mL, the nurse should administer 15mL/5mL/tsp=3tsp of medication.
