Question

A nurse is preparing to administer lorazepam 2 mg IV bolus 20 min prior to surgery. Available is lorazepam injection 4 mg/ml. How many ml should the nurse administer?

Answer 1

To administer lorazepam
`2 mg` IV bolus, the nurse should administer

`0.5 mL` of lorazepam injection 4 mg/mL.

Step-by-step explanation:

To calculate the number of mL that the nurse should administer, we can use the formula:

Dose (mg) = Volume (mL) x Concentration (mg/mL)

Given that the dose is
`2 mg`, and the concentration is we can rearrange the formula to solve for Volume:

Volume (mL) = Dose (mg) / Concentration (mg/mL)

Substituting the values, we get:

`Volume (mL) = 2 mg / 4 mg/mL = 0.5 mL`

Therefore, the nurse should administer
`0.5 mL` of lorazepam.
