For a patient requiring midazolam at 0.07 mg/kg, how many mL should be administered to a patient weighing 50 kg with a concentration of 5 mg/mL?

To determine the correct volume of midazolam to administer, start by calculating the total dosage required based on the patient's weight. The dosage is prescribed at 0.07 mg/kg for a patient weighing 50 kg.

1. Calculate the total dosage:

Total dosage = weight in kg × dosage in mg/kg

Total dosage = 50 kg × 0.07 mg/kg = 3.5 mg.

Next, since the concentration of the medication is 5 mg/mL, you can calculate the volume needed to achieve the total dosage:

2. Calculate the volume to administer:

Volume (mL) = Total dosage (mg) / Concentration (mg/mL)

Volume = 3.5 mg / 5 mg/mL = 0.7 mL.

The patient should receive 0.7 mL of midazolam based on the calculations. This answer aligns precisely with the dosing instructions provided in the question, making it the correct choice. Understanding these calculations is essential for ensuring accurate medication administration in nursing practice.
