A nurse is preparing to administer lorazepam 1 mg PO to an older adult client who has insomnia and who cannot swallow oral tablets.

Available is lorazepam oral solution 2 mg/mL. How many mL should the nurse plan to administer?
(Round to the nearest tenth. Use a leading zero if it applies.)

Step 1 is to calculate the amount of hydroxyzine HCL in each mL of the oral suspension. This is done by dividing the total amount of hydroxyzine HCL (25 mg) by the total volume (5 mL), which gives us 5 mg/mL. Step 2 is to calculate the volume of oral suspension that contains 50 mg of hydroxyzine HCL. This is done by dividing the prescribed dose (50 mg) by the concentration of the oral suspension (5 mg/mL). So, 50 mg ÷ 5 mg/mL = 10 mL.

So, the correct answer is 10 mL.

The amount available is potassium chloride liquid 40 mEq/15 mL. How many mL should the nurse administer?
