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 ["1.5"]
Explanation
To calculate the amount of phenobarbital injection needed for each dose after the initial dose, we need to divide the prescribed dose (200 mg) by the concentration of the injection (130 mg/mL). This gives us:
200 mg / 130 mg/mL = 1.538 mL
To round this to the nearest tenth, we look at the hundredths place and see that it is 3, which is less than 5, so we round down and drop the rest of the digits. This gives us:
1.5 mL
Therefore, the nurse should administer 1.5 mL of phenobarbital injection per dose after the initial dose.
Correct Answer is ["200"]
Explanation
To answer this question, we need to calculate the infusion rate of the IV pump. The formula for infusion rate is:
Infusion rate (mL/hr) = Volume (mL) / Time (hr)
We are given the volume of the solution, which is 50 mL, and the time of administration, which is 15 minutes or 0.25 hours. Plugging these values into the formula, we get:
Infusion rate (mL/hr) = 50 mL / 0.25 hr
Infusion rate (mL/hr) = 200 mL/hr
Therefore, the nurse should set the IV pump to deliver 200 mL/hr. This is the answer to the question.
