A nurse is preparing to administer loperamide 4mg PO to a client who is postpartum and has diarrhea. Available is loperamide liquid 1 mg/7.5 mL. How many mL 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.
The Correct Answer is ["30"]
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 ["2"]
Explanation
Given:
Prescribed dose: 100 mcg of fentanyl
Available concentration: 0.05 mg/mL
Steps to solve:
Convert mcg to mg:
1 mg = 1000 mcg
So, 100 mcg = 0.1 mg
Determine the volume to be administered:
Set up a proportion to solve for the unknown volume (X):
0.05 mg/mL = 0.1 mg/X mL
Cross-multiplying gives us:
0.05 mg x X mL = 0.1 mg x 1 mL
Simplifying:
0.05X = 0.1
Solving for X:
X = 0.1 / 0.05 = 2 mL
Correct Answer is ["1"]
Explanation
Given:
Prescribed dose: 0.25 mg of carboprost
Available concentration: 250 mcg/mL
Steps to solve:
Convert mg to mcg:
1 mg = 1000 mcg
So, 0.25 mg = 250 mcg
Determine the volume to be administered:
Set up a proportion to solve for the unknown volume (X):
250 mcg/mL = 250 mcg/X mL
Cross-multiplying gives us:
250 mcg x X mL = 250 mcg x 1 mL
Simplifying:
250X = 250
Solving for X:
X = 250 / 250 = 1 mL
