A nurse is preparing to administer 0.9% sodium chloride IV infusion 1-L bag at a rate of 200 mL/hr for a client who has rhabdomyolysis. The nurse should expect the IV pump to infuse over how many hours? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["5"]
To calculate the infusion time for a 1-L bag of 0.9% sodium chloride at a rate of 200 mL/hr, you would divide the total volume of the IV bag by the hourly infusion rate. Since there are 1000 mL in a 1-L bag, you would calculate 1000 mL divided by 200 mL/hr, which equals 5 hours.

Correct Answer is ["0.5"]
Explanation
To calculate the correct dose of digoxin, the nurse needs to convert the prescribed micrograms (mcg) to milligrams (mg) as the medication available is measured in mg. One milligram (mg) is equal to 1000 micrograms (mcg). Therefore, 125 mcg is equal to 0.125 mg. Since the available medication is 0.25 mg per tablet, the nurse would administer half a tablet to achieve the 0.125 mg dose.
