The Correct Answer is ["1.5"]
Calculating the Alprazolam Dose
Problem: Administer 0.75 mg of alprazolam PO. The available concentration is 0.5 mg/tablet.
Steps:
Set up a proportion:
We want to find the number of tablets needed.
We know the desired dose (0.75 mg) and the concentration of the medication (0.5 mg/tablet).
Proportion:
x tablets / 0.75 mg = 1 tablet / 0.5 mg
Cross-multiply:
0.5x = 0.75
Solve for x:
x = 0.75 / 0.5
x = 1.5
Answer: The nurse should administer 1.5 tablets of alprazolam per dose.

Correct Answer is ["200"]
Explanation
To calculate the infusion rate, we'll use the following formula:
Infusion Rate (mL/hour) = Total Volume (mL) / Infusion Time (hours)
First, convert minutes to hours:
75 minutes x (1 hour / 60 minutes) = 1.25 hours
Then, plug in the values into the formula:
Infusion Rate = 250 mL / 1.25 hours
Calculating the result:
Infusion Rate ≈ 200 mL/hour
Therefore, the nurse should program the secondary infusion pump to deliver 200 mL/hour.
