Question

the healthcare provider prescribes midazolam 3 mg iv for an older client prior to an endoscopic procedure. the available vial is labeled, midazolam hydrochloride injection 5 mg/ml. how many ml should the nurse prepare for administration to the client? (enter numerical value only. if rounding is required, round to the nearest tenth).

Explanation:

Step1: Recall the formula for dosage calculation

The formula to calculate the volume (in mL) of a medication to administer is \( \text{Volume} = \frac{\text{Desired Dose}}{\text{Available Concentration}} \). Here, the desired dose is 3 mg (the amount of midazolam the client needs), and the available concentration is 5 mg/mL (the amount of midazolam per milliliter of the injection).

Step2: Substitute the values into the formula

Substitute the desired dose (\( 3 \, \text{mg} \)) and the available concentration (\( 5 \, \text{mg/mL} \)) into the formula:
\( \text{Volume} = \frac{3 \, \text{mg}}{5 \, \text{mg/mL}} \)

Step3: Perform the calculation

Simplify the fraction: \( \frac{3}{5} = 0.6 \, \text{mL} \)

Answer:

0.6
