A nurse is preparing to administer cefazolin 40 mg/ke/day IV Golus divided in equal doses every 12 hr to neonate who weighs 5 kg. Available is cefazolin injection 330 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.3"]
Calculate the Total Daily Dose:
Dose: 40 mg/kg/day
Weight: 5 kg
Total Daily Dose: 40 mg/kg/day x 5 kg = 200 mg/day
Calculate the Dose Per Administration:
The dose is divided equally every 12 hours, meaning twice a day.
Dose Per Administration: 200 mg/day / 2 doses/day = 100 mg/dose
Calculate the Volume to Administer:
Available Concentration: 330 mg/mL
Volume (mL) = Desired Dose (mg) / Available Concentration (mg/mL)
Volume (mL) = 100 mg / 330 mg/mL
Volume (mL) ≈ 0.303 mL
Round to the Nearest Tenth:
0.3 mL

Correct Answer is ["667"]
Explanation
Understanding the Problem
Volume: 500 mL of 0.9% sodium chloride
Infusion Time: 45 minutes
Desired Rate: mL/hr
Step 1: Convert Infusion Time to Hours
Minutes in an Hour: 60 minutes
Infusion Time in Hours: 45 minutes / 60 minutes/hour = 0.75 hours
Step 2: Calculate the Infusion Rate in mL/hr
Volume: 500 mL
Infusion Time: 0.75 hours
Infusion Rate: 500 mL / 0.75 hours = 666.666... mL/hr
Step 3: Round to the Nearest Whole Number
The calculated rate is 666.666. mL/hr.
Rounded to the nearest whole number: 667 mL/hr
Answer: 667 mL/hr
Correct Answer is ["0.4"]
Explanation
Identify the Desired Dose and Available Concentration:
Desired Dose: 0.4 mg of naloxone
Available Concentration: 1 mg/mL (This means there is 1 mg of naloxone in every 1 mL of solution)
Set up the Calculation:
We need to find the volume (in mL) that contains the desired dose of 0.4 mg.
We can use the following formula:
Volume (mL) = Desired Dose (mg) / Available Concentration (mg/mL)
Plug in the Values and Calculate:
Volume (mL) = 0.4 mg / 1 mg/mL
Volume (mL) = 0.4 mL
Round to the Nearest Tenth (if necessary):
0.4 mL
