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 ["0.25"]
Explanation
Given:
Prescribed dose: 250 mcg of terbutaline
Available concentration: 1 mg/mL
Steps to solve:
Convert mg to mcg:
1 mg = 1000 mcg
1 mg/mL = 1000 mcg/mL
Determine the volume to be administered:
Set up a proportion to solve for the unknown volume (X):
1000 mcg/mL = 250 mcg/X mL
Cross-multiplying gives us:
1000 mcg x X mL = 250 mcg x 1 mL
Simplifying:
1000X = 250
Solving for X:
X = 250 / 1000 = 0.25 mL
Correct Answer is ["5"]
Explanation
Set up a proportion:
You have 50 mg of ibuprofen in 25 mL of suspension.
You need to administer 10 mg of ibuprofen.
Let 'x' represent the unknown volume in mL.
The proportion is: 50 mg / 25 mL = 10 mg / x mL
2. Solve for x:
Cross-multiply: 50 x x = 25 x 10
Simplify: 50x = 250
Divide both sides by 50: x = 250 / 50
Calculate: x = 5 mL
3. Round to the nearest hundredth:
5mL
