A nurse is preparing to administer bumetanide 5 mg, PO daily. Available is bumetanide 0.5 mg tablets. How many tablets should the nurse administer? (Round the answer to the nearest whole number. Use leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["3"]
Determine the desired dosage:
The nurse needs to administer 1.5 mg of bumetanide.
Determine the number of tablets per dose:
Each tablet contains 0.5 mg of bumetanide.
The nurse needs to administer 1.5 mg per dose.
To find the number of tablets per dose, we can set up a proportion:
0.5 mg / 1 tablet = 1.5 mg / x tablets
0.5x = 1.5
Dividing both sides by 0.5, we get:
x = 3 tablets

Correct Answer is ["1"]
Explanation
Convert the client's weight from pounds to kilograms:
There are 2.205 pounds in 1 kilogram.
146.7 lb = 146.7 lb / 2.205 lb/kg = 66.53 kg (rounded to two decimal places).
Determine the total dosage:
The client is prescribed 7.5 mg/kg of metronidazole.
The client weighs 66.53 kg.
The total dosage is 7.5 mg/kg x 66.53 kg = 498.975 mg.
Determine the number of tablets per dose:
Each tablet contains 500 mg of metronidazole.
The nurse needs to administer 498.975 mg per dose.
To find the number of tablets per dose, we can set up a proportion:
500 mg / 1 tablet = 498.975 mg / x tablets
Cross-multiplying gives us:
500x = 498.975
Dividing both sides by 500, we get:
x = 0.99795 tablets
Round the answer to the nearest whole number:
Rounding 0.99795 to the nearest whole number gives us 1 tablet.
Correct Answer is ["2"]
Explanation
1. Identify the desired dose:
- The physician has ordered lidocaine 200 mg per dose.
2. Identify the concentration of the available medication:
- The available lidocaine injection is 300 mg in 3 mL. This means the concentration is 300 mg / 3 mL.
3. Calculate the volume needed to deliver the desired dose using the formula:
- Desired Dose (mg) / Available Concentration (mg/mL) = Volume to Administer (mL)
4. Calculate the available concentration in mg/mL:
- Available Concentration = 300 mg / 3 mL = 100 mg/mL
5. Plug the values into the formula:
- Volume to Administer = 200 mg / 100 mg/mL
6. Solve for the volume to administer:
- Volume to Administer = 2 mL
7. Round the answer to the nearest whole number:
- The calculated volume is already a whole number (2).
8. Apply leading zero if it applies:
- A leading zero is not needed as the answer is a whole number greater than or equal to 1.
9. Ensure no trailing zero is used:
- The answer is 2, with no trailing zero.
Answer: The nurse should administer 2 mL per dose.
