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

Prescribed dose: 1 mg of phytonadione
Available concentration: 1 mg/0.5 mL
Steps to solve:
Concentration: 1 mg/0.5 mL
To administer 1 mg of phytonadione, the nurse needs to administer exactly 0.5 mL.
Correct Answer is ["200"]
Explanation
Given:
Total volume: 1000 mL
Time: 5 hours
Steps to solve:
Determine the flow rate:
Set up a proportion to solve for the unknown flow rate (X):
1000 mL/5 hr = X mL/1 hr
Cross-multiplying gives us:
1000 mL x 1 hr = 5 hr x X mL
Simplifying:
1000 = 5X
Solving for X:
X = 1000 / 5 = 200 mL/hr
