A nurse is preparing to administer metoclopramide 15 mg IV. Available is metoclopramide 5 mg/mL. How many mi should ye nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. do not use a trailing zero.).
The Correct Answer is ["3"]
Understanding the Problem
Order: Metoclopramide 15 mg IV
Available Solution: Metoclopramide 5 mg/mL
Desired Dose: mL to administer
Step 1: Set Up the Calculation
We need to find the volume (in mL) that contains the ordered dose (15 mg). We can do this by dividing the ordered dose by the concentration of the available solution:
Volume (mL) = Ordered Dose (mg) / Concentration (mg/mL)
Step 2: Perform the Calculation
Ordered Dose: 15 mg
Concentration: 5 mg/mL
Volume: 15 mg / 5 mg/mL = 3 mL
Step 3: Round to the Nearest Whole Number
The result is 3 mL, which is already a whole number.
Answer: 3 mL

Correct Answer is ["167"]
Explanation
Understanding the Problem
Volume: 250 mL of 0.9% sodium chloride
Infusion Time: 90 minutes
Desired Rate: mL/hr
Step 1: Convert Infusion Time to Hours
Minutes in an Hour: 60 minutes
Infusion Time in Hours: 90 minutes / 60 minutes/hour = 1.5 hours
Step 2: Calculate the Infusion Rate in mL/hr
Volume: 250 mL
Infusion Time: 1.5 hours
Infusion Rate: 250 mL / 1.5 hours = 166.666... mL/hr
Step 3: Round to the Nearest Whole Number
The calculated rate is 166.666... mL/hr.
Rounded to the nearest whole number: 167 mL/hr
Answer: 167 mL/hr
Correct Answer is ["4"]
Explanation
Identify the Desired Dose and Available Concentration:
Desired Dose: 5 mg of enalapril
Available Concentration: 1.25 mg/mL (This means there are 1.25 mg of enalapril in every 1 mL of solution)
Set up the Calculation:
We need to find the volume (in mL) that contains the desired dose of 5 mg.
We can use the following formula:
Volume (mL) = Desired Dose (mg) / Available Concentration (mg/mL)
Plug in the Values and Calculate:
Volume (mL) = 5 mg / 1.25 mg/mL
Volume (mL) = 4 mL
Round to the Nearest Whole Number (if necessary):
4mL
