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 ["168"]
Explanation
Here's how to calculate the total zidovudine dosage (mg) the nurse should prepare to administer:
1. Convert client weight from pounds to kilograms:
Client weight (kg) = Client weight (lb) / 2.2
Client weight (kg) = 185 lb / 2.2
Client weight (kg) = 84.1 kg (approximately)
2. Calculate the total zidovudine dose based on weight and prescribed dosage:
Dose (mg) = Dose (mg/kg) x Client weight (kg)
Dose (mg) = 2 mg/kg x 84.1 kg
Dose (mg) = 168.2 mg (round to nearest whole number as requested)
Therefore, the nurse should prepare to administer 168 mg of zidovudine.
Correct Answer is ["200"]
Explanation
Here's why:
The entire dose (400 mg) is contained within the 200 mL bag.
The information doesn't suggest the bag needs to be emptied completely during the infusion.
Our goal is to deliver the 400 mg dose over the 1-hour infusion period.
Therefore, the nurse should program the infusion pump to deliver the entire volume of the bag (200 mL) containing the medication over the 1-hour timeframe.
Calculation:
Volume to deliver (mL/hr) = Total volume of bag (mL) / Infusion time (hours)
Volume to deliver (mL/hr) = 200 mL / 1 hour
Volume to deliver (mL/hr) = 200 mL/hr
Therefore, the nurse should program the infusion pump to deliver 200 mL/hr.
