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

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
Correct Answer is ["0.67"]
Explanation
Given:
Prescribed dose: 5,000 units of heparin
Available concentration: 7,500 units/mL
Steps to solve:
Determine the volume to be administered:
Set up a proportion to solve for the unknown volume (X):
7,500 units/mL = 5,000 units/X mL
Cross-multiplying gives us:
7,500 units x X mL = 5,000 units x 1 mL
Simplifying:
7,500X = 5,000
Solving for X:
X = 5,000 / 7,500 = 0.67 mL
