A nurse is preparing to administer enoxaparin 75mg subcutaneous once daily to an antepartum client who has a clotting disorder. Available is enoxaparin injection 100 mg/mL. How many mL should the nurse administer? Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero
The Correct Answer is ["0.75"]
Given:
Prescribed dose: 75 mg of enoxaparin
Available concentration: 100 mg/mL
Steps to solve:
Determine the volume to be administered:
Set up a proportion to solve for the unknown volume (X):
100 mg/mL = 75 mg/X mL
Cross-multiplying gives us:
100 mg x X mL = 75 mg x 1 mL
Simplifying:
100X = 75
Solving for X:
X = 75 / 100 = 0.75 mL

Explanation
Given:
Prescribed dose: 12.5 mg of promethazine
Available tablets: 25 mg tablets
Steps to solve:
Determine the number of tablets per dose:
Find how many 25 mg tablets are needed to make 12.5 mg of promethazine.
Set up a proportion to solve for the unknown number of tablets (X):
25 mg/tablet = 12.5 mg/X tablets
Cross-multiplying gives us:
25 mg x X tablets = 12.5 mg x 1 tablet
Simplifying:
25X = 12.5
Solving for X:
X = 12.5 / 25 = 0.5 tablets
Correct Answer is ["2"]
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
