A nurse is assisting with the care of a client who is in preterm labor and has a prescription for terbutaline 250 mcg subcutaneously, every 20 min. Available is terbutaline 1 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest hundredth. Use a leading zero d applies Do not use a trailing zero)
The Correct Answer is ["0.25"]
Given:
Prescribed dose: 250 mcg of terbutaline
Available concentration: 1 mg/mL
Steps to solve:
Convert mg to mcg:
1 mg = 1000 mcg
1 mg/mL = 1000 mcg/mL
Determine the volume to be administered:
Set up a proportion to solve for the unknown volume (X):
1000 mcg/mL = 250 mcg/X mL
Cross-multiplying gives us:
1000 mcg x X mL = 250 mcg x 1 mL
Simplifying:
1000X = 250
Solving for X:
X = 250 / 1000 = 0.25 mL

Correct Answer is ["30"]
Explanation
Given:
Prescribed dose: 4 mg of loperamide
Available concentration: 1 mg/7.5 mL
Steps to solve:
Determine the volume to be administered:
Set up a proportion to solve for the unknown volume (X):
1 mg/7.5 mL = 4 mg/X mL
Cross-multiplying gives us:
1 mg x X mL = 4 mg x 7.5 mL
Simplifying:
X = 30
Correct Answer is ["2500"]
Explanation
The problem: Administer 2.5 L of lactated Ringer's solution.
1 liter (L) = 1000 milliliters (mL).
To convert 2.5 L to mL, we multiply:
2.5 L x 1000 mL/L = 2500 mL
