Order: Metoprolol 3.5 mg IV push
On hand: 1 mg/mL vials
How many milliliters will the nurse draw up to administer this dose?
No answer is provided
No answer is too low
No answer is too high
3.5
The Correct Answer is D
Choice A reason: This choice is incorrect because it does not provide a numerical answer to the question.
Choice B reason: This choice is incorrect because it does not provide a specific answer to the question. It also implies that there is an answer that is lower than the correct one, which is not true.
Choice C reason: This choice is incorrect because it does not provide a specific answer to the question. It also implies that there is an answer that is higher than the correct one, which is not true.
Choice D reason: This choice is correct because it is the result of dividing the ordered dose (3.5 mg) by the concentration of the vial (1 mg/mL). The formula for calculating the volume to be drawn up is:
Volume = Dose/Concentration
Therefore, the volume to be drawn up is:
Volume = 3.5 mg/(1 mg/mL) = 3.5 mL

Correct Answer is ["0.71"]
Explanation
To calculate how many milliliters (mL) of the reconstituted medication the nurse should administer, we can use the following formula:
Desired dose (in mg) / Stock concentration (in mg/mL) = Volume to administer (in mL)
Given information:
Desired dose of ceftriaxone: 250 mg
Stock concentration after reconstitution: 350 mg/mL
Now let's calculate the volume to administer:
250 mg / 350 mg/mL = 0.7143 mL
Rounding to the nearest hundredth, the nurse should administer 0.71 mL of the reconstituted medication.
Correct Answer is ["25"]
Explanation
To calculate the IV flow rate in drops per minute (gtt/min) for the administration of clindamycin, we can follow these steps:
First, we need to determine the total number of minutes for the infusion, which is given as 1 hour:
1 hour × 60 minutes/hour = 60 minutes
Next, we calculate the total number of drops needed for the infusion:
The total volume to be infused is 100 mL.
The drop factor is 15 gtt/mL.
100 mL × 15 gtt/mL = 1500 gtt
Calculate the IV flow rate in drops per minute:
1500 gtt ÷ 60 min = 25 gtt/min
Rounding to the nearest whole number, the nurse should set the IV flow rate to deliver 25 gtt/min.
