A patient is ordered 5 mg of IV Lopressor (metoprolol tartrate) to be administered over 60 seconds. The concentration is 1 mg/1 mL.
How many milliliters per minute should the nurse administer to the patient?
0.008 mL
1 mL
5 mL
300 mL
The Correct Answer is C
The patient is ordered to receive 5 mg of Lopressor over 60 seconds, which is equivalent to 1 minute. The concentration of Lopressor is 1 mg/1 mL, which means there is 1 mg of Lopressor in 1 mL of solution. To calculate how many milliliters per minute the nurse should administer, we can use the following formula:
5 mg / 1 mg per 1 mL = X mL X = 5 mL per minute.

Correct Answer is D
Explanation
To calculate the time it will take to finish the infusion, we can use the formula:
Time = Volume / Rate
Plugging in the given values, we get: Time = 1.5 L / 75 mL/hr
Converting 1.5 L to mL, we get:
Time = 1500 mL / 75 mL/hr Simplifying, we get:
Time = 20 hours
Therefore, it will take 20 hours to finish the infusion at the current rate.
Correct Answer is C
Explanation
To calculate the total amount of medication the client should receive, multiply the volume of the medication by its concentration:
500 mL x 2 mg/mL = 1000 mg
Therefore, the client should receive 1000 mg of the medication.
