The healthcare provider prescribes furosemide 120 mg intravenously (IV) for a client with fluid overload. Furosemide is available in a vial labeled 10 mg/mL, and the recommended rate for IV administration is 40 mg/minute. The nurse should administer the medication over what length of time in minutes? (Enter numeric value only.)
The Correct Answer is ["3"]
Here's how to calculate the duration (minutes) for the nurse to administer furosemide:
Prescribed dose: 120 mg furosemide (given)
Recommended rate: 40 mg/minute (given)
We need to find the total time (minutes) required to administer the prescribed dose (120 mg) at the recommended rate (40 mg/minute).
Time (minutes) = Dose (mg) / Rate (mg/minute)
Time (minutes) = 120 mg / 40 mg/minute
Time (minutes) = 3 minutes
Therefore, the nurse should administer the medication over 3 minutes.

Correct Answer is ["0.9"]
Explanation
Here's how to calculate the total volume the nurse should administer for the combined medication:
1. Calculate the volume of hydromorphone:
Dose: 4 mg
Concentration: 10 mg/mL (from ampule label)
Volume (mL) for hydromorphone = Dose (mg) / Concentration (mg/mL)
Volume (mL) for hydromorphone = 4 mg / 10 mg/mL
Volume (mL) for hydromorphone = 0.4 mL
2. Calculate the volume of hydroxyzine:
Dose: 25 mg
Concentration: 50 mg/mL (from vial label)
Volume (mL) for hydroxyzine = Dose (mg) / Concentration (mg/mL)
Volume (mL) for hydroxyzine = 25 mg / 50 mg/mL
Volume (mL) for hydroxyzine = 0.5 mL
3. Add the volumes for each medication to find the total volume:
Total volume = Volume (mL) for hydromorphone + Volume (mL) for hydroxyzine
Total volume = 0.4 mL + 0.5 mL
Total volume = 0.9 mL (round to nearest tenth as requested)
Therefore, the nurse should administer a total of 0.9 mL.
Correct Answer is ["1.5"]
Explanation
First, we need to convert the prescribed dose from mg to mcg because the available medication is labeled in mcg.
1 mg is equal to 1,000 mcg. So, 0.075 mg is equal to 75 mcg.
Given:
The prescription is for 75 mcg of levothyroxine.
The available medication is 50 mcg/tablet.
We can set up the proportion as follows:
75mcg/ xtablet = 50mcg/1tablet
Solving for x gives us the number of tablets that the nurse should administer.
Cross-multiplying and solving for x:
X = 75mcg×1tablet/50mcg
After performing the calculation, we find that x equals 1.5 tablets.
So, the nurse should administer 1.5 tablets of the medication. This is rounded to the nearest tenth as per the instructions.
