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 ["2.5"]
Explanation
Given:
Prescribed dose: 250 mg of ciprofloxacin per dose
Available tablets: 100 mg tablets
Steps to solve:
Determine the number of tablets per dose:
Find how many 100 mg tablets are needed to make 250 mg of ciprofloxacin.
Set up a proportion to solve for the unknown number of tablets (X):
100 mg/tablet = 250 mg/X tablets
Cross-multiplying gives us:
100 mg x X tablets = 250 mg x 1 tablet
Simplifying:
100X = 250
Solving for X:
X = 250 / 100 = 2.5 tablets
Correct Answer is ["100"]
Explanation
Given:
Total volume: 100 mL
Time: 60 minutes
Steps to solve:
Determine the flow rate:
Set up a proportion to solve for the unknown flow rate (X):
100 mL/60 min = X mL/1 min
Cross-multiplying gives us:
100 mL x 1 min = 60 min x X mL
Simplifying:
100 = 60X
Solving for X:
X = 100 / 60 = 1.67 mL/min
Convert to mL/hr:
1.67 mL/min x 60 min/hr = 100 mL/hr
