For a client prescribed hydrochlorothiazide 25 mg PO daily and with a concentration of 50mg/5mL, how many mL should the nurse administer?

To determine the correct volume to administer for hydrochlorothiazide at a prescribed dose of 25 mg with a concentration of 50 mg per 5 mL, you can use a simple calculation.

First, find out how much medication is contained in 1 mL. Since the concentration is 50 mg in 5 mL, you can calculate the amount per mL by dividing the total mg by the volume in mL:

50 mg / 5 mL = 10 mg/mL.

Next, to find out how many mL are needed to deliver a dose of 25 mg, divide the prescribed dose by the concentration per mL:

25 mg / 10 mg/mL = 2.5 mL.

Therefore, to administer the correct dose of 25 mg, the nurse should give 2.5 mL of the medication. This calculation aligns with the correct answer and ensures that the agent is given at the appropriate dosage to achieve the desired therapeutic effect.
