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 ["188"]
Explanation
Given:
Total volume: 1500 mL
Time: 8 hours
Steps to solve:
Determine the flow rate:
Set up a proportion to solve for the unknown flow rate (X):
1500 mL/8 hr = X mL/1 hr
Cross-multiplying gives us:
1500 mL x 1 hr = 8 hr x X mL
Simplifying:
1500 = 8X
Solving for X:
X = 1500 / 8 = 187.5 mL/hr
Round to the nearest whole number:
188 mL/hr.
Correct Answer is ["2"]
Explanation
Given:
Prescribed dose: 10 mg of metoclopramide
Available concentration: 5 mg/mL
Steps to solve:
Determine the volume to be administered:
Set up a proportion to solve for the unknown volume (X):
5 mg/mL = 10 mg/X mL
Cross-multiplying gives us:
5 mg x X mL = 10 mg x 1 mL
Simplifying:
5X = 10
Solving for X:
X = 10 / 5 = 2 mL
