A nurse is preparing to administer iron dextran 75mg IM, to a client who is pregnant, has iron deficiency anemia and cannot tolerate oral iron supplements. Available as iron dextran 50 mg/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 ["1.5"]
Given:
Prescribed dose: 75 mg of iron dextran
Available concentration: 50 mg/mL
Steps to solve:
Determine the volume to be administered:
Set up a proportion to solve for the unknown volume (X):
50 mg/mL = 75 mg/X mL
Cross-multiplying gives us:
50 mg x X mL = 75 mg x 1 mL
Simplifying:
50X = 75
Solving for X:
X = 75 / 50 = 1.5 mL

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 ["0.5"]
