A doctor orders 0.1 mg of Synthroid (levothyroxine), and 50 mcg tablets are available.
How many tablets per dose should the nurse administer to this patient?

A.

1 tablet

B.

3 tablets

C.

4 tablets

D.

2 tablets

Answer and Explanation

The Correct Answer is D

The nurse should administer 2 tablets per dose to this patient.

This answer is correct because it is based on a simple unit conversion and ratio and proportion calculation. The nurse can convert 0.1 mg to 100 mcg by multiplying by 1000, since there are 1000 mcg in 1 mg. Then, the nurse can set up a proportion as follows:

50 mcg / 1 tablet = 100 mcg / x tablets

Cross-multiplying and solving for x gives:

x = 2 tablets

Therefore, the nurse should administer 2 tablets of Synthroid to deliver 0.1 mg or 100 mcg of the medication to the patient.

Correct Answer is B

Explanation

Step 1 is Convert pounds to kilograms 110 lb ÷ 2.2 = 50 kg

Step 2 is Calculate dose in micrograms per minute 50 kg × 200 micrograms = 10,000 micrograms/min

Step 3 is Convert micrograms to milligrams 10,000 micrograms ÷ 1000 = 10 mg/min

Step 4 is Convert mg/min to mg/hr 10 mg × 60 = 600 mg/hr

Step 5 is Determine concentration of esmolol in mg/mL 2.5 grams × 1000 = 2500 mg 2500 mg ÷ 250 mL = 10 mg/mL

Step 6 is Calculate infusion rate in mL/hr 600 mg/hr ÷ 10 mg/mL = 60 mL/hr

Correct Answer is C

Explanation

To find the hours to finish the infusion, you need to calculate the following:

- The volume of saline solution in milliliters
- The time in hours using the formula: Time (h) = Total volume (mL) / Infusion rate (mL/h)


First, convert the volume of saline solution from liters to milliliters by multiplying by 1000:

1.5 L x 1000 = 1500 mL


Next, use the formula for time to find how many hours it will take to infuse the saline solution at the current rate:


Time (h) = Total volume (mL) / Infusion rate (mL/h)


Since the total volume is 1500 mL and the infusion rate is 75 mL/h, plug in these values into the formula:


Time (h) = 1500 mL / 75 mL/h


Simplify and solve for the time:


Time (h) = 20 h


Therefore, it will take **20 hours** to finish the infusion at the current rate.
