The health-care provider prescribes furosemide 15 mg IM STAT. The available ampoule is labeled, furosemide 10 mg/ml. How many milliliters should the nurse administer? (Enter the numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["1.5"]
Understanding the Problem:
We need to administer 15 mg of furosemide.
The available ampoule contains 10 mg/mL of furosemide.
Solution:
Set up a proportion:
We want to find the number of milliliters (mL) needed.
We know the desired dose (15 mg) and the concentration of the medication (10 mg/mL).
Proportion:
x mL / 15 mg = 1 mL / 10 mg
Cross-multiply:
10x = 15
Solve for x:
x = 15 / 10
x = 1.5
Therefore, the nurse should administer 1.5 mL of furosemide.

Correct Answer is ["16.8"]
Explanation
To calculate the volume of IV solution needed to dilute the nafcillin, we'll follow these steps:
Step 1: Calculate the total volume of the diluted solution:
Desired Concentration (mg/mL) = Prescribed Dose (mg) / Total Volume (mL)
Rearranging the formula to solve for Total Volume:
Total Volume (mL) = Prescribed Dose (mg) / Desired Concentration (mg/mL)
Total Volume = 800 mg / 40 mg/mL
Total Volume = 20 mL
Step 2: Calculate the volume of nafcillin solution to be added:
Volume of Nafcillin Solution = Prescribed Dose (mg) / Concentration of Nafcillin (mg/mL)
Volume of Nafcillin Solution = 800 mg / 250 mg/mL
Volume of Nafcillin Solution = 3.2 mL
Step 3: Calculate the volume of IV solution needed to dilute:
Volume of IV Solution = Total Volume - Volume of Nafcillin Solution
Volume of IV Solution = 20 mL - 3.2 mL
Volume of IV Solution = 16.8 mL
Therefore, the nurse should add 16.8 mL of IV solution to the volume control device to dilute the nafcillin.
Correct Answer is ["3"]
Explanation
First, let's convert grams to milligrams:
0.3 grams x 1000 mg/gram = 300 mg
Then, set up a proportion:
x capsules / 300 mg = 1 capsule / 100 mg
Cross-multiply:
100x = 300
Solve for x:
x = 300 / 100
x = 3
Therefore, the nurse should administer 3 capsules of docusate sodium (Colace).
