nurse is preparing to administer hydroxyzine HCL 50 mg PO. Available is hydroxyzine oral suspension 25 mg/5 mL. How many mL should the nurse administer? (Round the answer to the nearest whole number.
Use a leading zero if it applies.
Do not use a trailing zero
The Correct Answer is ["10"]
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.

Correct Answer is ["0.5"]
Explanation
Step 1 is to determine the amount of lorazepam that needs to be administered, which is 1 mg.
Step 2 is to calculate the volume of lorazepam oral solution needed to deliver this dose. This is done using the formula:
Dose (mg) ÷ Concentration (mg/mL)
Given that the solution has a concentration of 2 mg/mL, we calculate:
1 mg ÷ 2 mg/mL = 0.5 mL
Therefore, the nurse should administer 0.5 mL of lorazepam oral solution.
