Answer and Explanation

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 ["167"]

Explanation

To calculate the infusion rate, we'll use the following formula:

Infusion Rate (mL/hour) = Total Volume (mL) / Infusion Time (hours)

Plugging in the given values:

Infusion Rate = 1000 mL / 6 hours

Calculating the result:

Infusion Rate ≈ 166.67 mL/hour

Rounding to the nearest whole number, the nurse should program the infusion pump to deliver 167 mL/hour

Correct Answer is ["40"]

Explanation

Calculating the Inamrinone Infusion Rate

Step 1: Convert weight to kilograms:

183 lbs x (1 kg / 2.20462 lbs) ≈ 83.0 kg

Step 2: Calculate the desired dose rate in mcg/minute:

8 mcg/kg/minute x 83.0 kg ≈ 664 mcg/minute

Step 3: Calculate the concentration of inamrinone in the IV solution:

0.1 grams/100 mL = 100 mg/100 mL = 1 mg/mL

Step 4: Calculate the infusion rate in mL/hour:

First, convert mcg to mg:

664 mcg x (1 mg / 1000 mcg) = 0.664 mg/minute

Then, set up a proportion:

x mL/hour / 0.664 mg/minute = 60 minutes/hour / 1 mg/mL

Cross-multiply and solve for x:

x mL/hour = 0.664 mg/minute x 60 minutes/hour / 1 mg/mL

x mL/hour ≈ 40 mL/hour

Therefore, the nurse should program the infusion pump to deliver approximately 40 mL/hour.
