A nurse is preparing to administer prednisone 0.04 g PO. Available is prednisone 20 mg tablets. How many tablets should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["2"]

To find out how many tablets of prednisone the nurse should administer, we need to convert the prescribed dose from grams to milligrams.

There are 1000 milligrams in 1 gram. Therefore, to convert 0.04 g to mg, we multiply 0.04 by 1000.

This gives us 40 mg. Since each tablet contains 20 mg of prednisone, the nurse should administer 40/20 = 2

tablets. The answer is rounded to the nearest whole number as instructed.

Correct Answer is ["0.65"]

Explanation

Let’s calculate this step by step:

Step 1: Convert the toddler’s weight from pounds (lb) to kilograms (kg) using the conversion factor 1 kg = 2.2 lbs.

24 lbs ÷ 2.2 lbs/kg = 10.91 kg

Step 2: Calculate the total amount of diazepam needed using the dosage of 0.3 mg/kg.

0.3 mg/kg × 10.91 kg = 3.27 mg

Step 3: Calculate the volume of diazepam injection to administer using the concentration of 5 mg/mL.

3.27 mg ÷ 5 mg/mL = 0.654 mL

Rounding to the nearest hundredth, the nurse should administer 0.65 mL of diazepam injection.

Correct Answer is ["125"]

Explanation

To find out how many mL/hr the IV pump should be set to deliver, we need to divide the total volume of the infusion by the infusion time in hours.

If 1,000 mL of 0.45% sodium chloride is to be infused over 8 hours, then the rate of infusion is 1,000/8 = 125 mL/hr.

The answer is rounded to the nearest whole number as instructed.
