A nurse is preparing to administer carboprost 0.25 mg IM to a client who is experiencing postpartum hemorrhage following a vaginal birth. Available is carboprost injection 250 mcg/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 ["1"]
Given:
Prescribed dose: 0.25 mg of carboprost
Available concentration: 250 mcg/mL
Steps to solve:
Convert mg to mcg:
1 mg = 1000 mcg
So, 0.25 mg = 250 mcg
Determine the volume to be administered:
Set up a proportion to solve for the unknown volume (X):
250 mcg/mL = 250 mcg/X mL
Cross-multiplying gives us:
250 mcg x X mL = 250 mcg x 1 mL
Simplifying:
250X = 250
Solving for X:
X = 250 / 250 = 1 mL

Explanation
Given:
Prescribed dose: 30 mEq of potassium chloride per dose
Available tablets: 10 mEq tablets
Steps to solve:
Determine the number of tablets per dose:
Find how many 10 mEq tablets are needed to make 30 mEq of potassium chloride.
Set up a proportion to solve for the unknown number of tablets (X):
10 mEq/tablet = 30 mEq/X tablets
Cross-multiplying gives us:
10 mEq x X tablets = 30 mEq x 1 tablet
Simplifying:
10X = 30
Solving for X:
X = 30 / 10 = 3 tablets
Correct Answer is ["2"]
Explanation
Given:
Prescribed dose: 100 mcg of fentanyl
Available concentration: 0.05 mg/mL
Steps to solve:
Convert mcg to mg:
1 mg = 1000 mcg
So, 100 mcg = 0.1 mg
Determine the volume to be administered:
Set up a proportion to solve for the unknown volume (X):
0.05 mg/mL = 0.1 mg/X mL
Cross-multiplying gives us:
0.05 mg x X mL = 0.1 mg x 1 mL
Simplifying:
0.05X = 0.1
Solving for X:
X = 0.1 / 0.05 = 2 mL
