The healthcare provider prescribes 0.075 mg of levothyroxine PO daily. The medication is labeled, "50 mcg tablets." How many tablets should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["1.5"]
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:
75 mcg/ x tablet = 50 mcg/1 tablet
Solving for x gives us the number of tablets that the nurse should administer.
Cross-multiplying and solving for x:
X = 75 mcg×1 tablet/50 mcg
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.

Correct Answer is ["22.9"]
Explanation
First, let’s convert the client’s weight from pounds to kilograms since the dosage is prescribed in mcg/kg/min. We know that 1 kg is approximately 2.2 lbs. So,
Weightinkg = 140lbs/2.2 ≈ 63.64kg
The prescribed dose is 6 mcg/kg/min. Therefore, the total dose for this client per minute would be:
Doseperminute=6mcg/kg/min×63.64kg = 381.84mcg/min
We need to convert this to mcg/hr since we want the rate in mL/hr and our final concentration is in mcg/mL. There are 60 minutes in an hour, so:
Doseperhour = 381.84mcg/min×60 = 22910.4mcg/hr
The IV bag contains 250 mg of dobutamine in 250 mL of solution. This is equivalent to 250,000 mcg in 250 mL, or 1000 mcg/mL.
Finally, we can find the rate in mL/hr by dividing the dose per hour by the concentration:
RateinmL/hr = 22910.4mcg/hr / 1000mcg/mL = 22.91mL/hr
If rounding is required to the nearest tenth, the nurse should program the infusion pump to deliver 22.9 mL/hr.
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.
