The health-care provider prescribes furosemide (Lasix) 25 mg IV. The drug is available in a solution of 40 mg/4ml. How many ml should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["2.5"]
To calculate the volume of furosemide to be administered, we can use the following formula:
Volume to administer = (Prescribed dose) / (Concentration)
Plugging in the given values:
Volume to administer = 25 mg / (40 mg/4 mL)
Volume to administer = 25 mg x (4 mL / 40 mg)
Volume to administer = 2.5 mL
Therefore, the nurse should administer 2.5 mL of furosemide (Lasix).

Correct Answer is ["167"]
Explanation
To calculate the infusion rate, we'll use the following formula:
Infusion Rate (mL/hour) = Total Volume (mL) / Infusion Time (hours)
Plugging in the given values:
Infusion Rate = 1000 mL / 6 hours
Calculating the result:
Infusion Rate ≈ 166.67 mL/hour
Rounding to the nearest whole number, the nurse should program the infusion pump to deliver 167 mL/hour
Correct Answer is ["140"]
Explanation
Understanding the Problem:
We need to prepare a 280 ml tube feeding of Ensure that's 50% strength.
Full-strength Ensure comes in 240 ml cans.
Solution:
Determine the volume of Ensure needed:
Since we want a 50% solution, we need to dilute the full-strength Ensure by half.
So, we need 280 ml / 2 = 140 ml of full-strength Ensure.
Therefore, the nurse should use 140 ml of Ensure to prepare the feeding.
