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? (round the answer to the nearest tenth. use a leading zero if it applies. do not use a trailing zero.)

Explanation:

Step1: Recall the formula for dosage calculation

The formula to calculate the volume of medication to administer is \(\text{Volume (mL)}=\frac{\text{Dose Required (mg)}}{\text{Concentration (mg/mL)}}\).

Step2: Substitute the given values

We know the dose required is \(2\space mg\) and the concentration is \(4\space mg/mL\). Substituting these values into the formula, we get \(\text{Volume}=\frac{2}{4}\).

Step3: Perform the calculation

\(\frac{2}{4} = 0.5\).

Answer:

\(0.5\)
