A nurse is preparing to administer verapamil 10 mg IV bolus. Available is verapamil injection 5 mg/2 mL. How many mL should the 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 ["4"]
To administer verapamil 10 mg IV bolus, the nurse should use the following formula: mL = (mg / mg/mL) x mL. Plugging in the values from the question, we get: mL = (10 / 5) x 2. Simplifying, we get: mL = 4. Therefore, the nurse should administer 4 mL of verapamil injection.

Correct Answer is ["50"]
Explanation
To calculate the flow rate in drops per minute (gtt/min), you can use the formula:
Flow rate (gtt/min) = Volume (mL) × Drop factor (gtt/mL) ÷ Time (min)
Given:
Volume = 1000 mL
Drop factor = 12 gtt/mL
Time = 4 hours
Convert 4 hours to minutes:
4 hours × 60 minutes/hour = 240 minutes
Then
Flow rate (gtt/min) = 1000 mL × 12 gtt/mL ÷ 240 min
Flow rate (gtt/min) = 12000 gtt ÷ 240 min
Flow rate (gtt/min) = 50 gtt/min
Therefore, the nurse should regulate the flow rate to deliver 50 gtt/min.
Correct Answer is ["0.4"]
Explanation
- To calculate the amount of morphine injection needed, use the formula: D/H x V = A, where D is the desired dose, H is the dose on hand, V is the volume on hand, and A is the amount to administer.
- Plug in the values from the question: 4 mg / 10 mg x 1 ml = 0.4 ml
- Round the answer to the nearest tenth: 0.4 ml
- The nurse should administer 0.4 ml of morphine injection.
