Question

A client is prescribed famotidine (Pepcid) 20 mg IVP Q 12 hours. The vial is labeled Pepcid 10 mg/mL. How many mL should you administer? (Place only the numerical value in the space provided.)

Answer 1

To administer a 20 mg dose of famotidine from a vial with a concentration of 10 mg/mL, the correct volume to administer is 2 mL.

Step-by-step explanation:

The student is asking how many milliliters (mL) of famotidine (Pepcid) should be administered when the prescribed dose is 20 mg and the vial concentration is 10 mg/mL. To calculate this, one would use the formula:Dose (mg) ÷ Concentration (mg/mL) = Volume to administer (mL).Substituting the prescribed dose and the concentration into the formula20 mg ÷ 10 mg/mL = 2 mL

Therefore, you need to administer 2 mL of the famotidine solution to deliver a 20 mg dose.To determine how many mL should be administered, you need to calculate the total dose of famotidine required by the client and divide it by the concentration of the vial. The client requires 20 mg of famotidine, and the vial contains 10 mg/mL. Therefore, you would divide 20 mg by 10 mg/mL to get 2 mL. Therefore, you should administer 2 mL of famotidine.
