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 ["1"]
Explanation
To calculate the number of capsules needed, we'll first convert grams to milligrams:
0.1 grams x 1000 mg/gram = 100 mg
Then, we can set up a proportion:
x capsules / 100 mg = 1 capsule / 100 mg
Cross-multiplying:
100x = 100
Solving for x:
x = 100 / 100
x = 1
Therefore, the nurse should administer 1 capsule of Dantrolene.
Correct Answer is ["1.5"]
Explanation
Understanding the Problem:
We need to administer 15 mg of furosemide.
The available ampoule contains 10 mg/mL of furosemide.
Solution:
Set up a proportion:
We want to find the number of milliliters (mL) needed.
We know the desired dose (15 mg) and the concentration of the medication (10 mg/mL).
Proportion:
x mL / 15 mg = 1 mL / 10 mg
Cross-multiply:
10x = 15
Solve for x:
x = 15 / 10
x = 1.5
Therefore, the nurse should administer 1.5 mL of furosemide.
