A nurse is preparing to administer ferrous sulfate 120 mg PO. Available is ferrous sulfate syrup 90 mg/5 mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["6.7"]
Given:
Prescribed dose: 120 mg of ferrous sulfate
Available concentration: 90 mg/5 mL
Steps to solve:
Determine the volume to be administered:
Set up a proportion to solve for the unknown volume (X):
90 mg/5 mL = 120 mg/X mL
Cross-multiplying gives us:
90 mg x X mL = 120 mg x 5 mL
Simplifying:
90X = 600
Solving for X:
X = 600 / 90 = 6.67 mL
Round to the nearest tenth: 6.7 mL

Correct Answer is ["2"]
Explanation
Given:
Total daily dose: 300 mg of propylthiouracil per day
Number of doses per day: 3 doses
Available tablets: 50 mg tablets
Steps to solve:
Determine the dose per administration:
Since the daily dose is divided into three doses, each dose will be: 300 mg/day ÷ 3 doses/day = 100 mg/dose
Determine the number of tablets per dose:
Find how many 50 mg tablets are needed to make 100 mg of propylthiouracil.
Set up a proportion to solve for the unknown number of tablets (X):
50 mg/tablet = 100 mg/X tablets
Cross-multiplying gives us:
50 mg x X tablets = 100 mg x 1 tablet
Simplifying:
50X = 100
Solving for X:
X = 100 / 50 = 2 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
