(Round the answer to the nearest whole Itlit.41N. uses loading zero if it applies Do not use a trading zero.)
The Correct Answer is ["20"]
Given:
Total units of heparin: 25,000 units
Total volume: 250 mL
Desired infusion rate: 2000 units/hr
Steps to solve:
Determine the infusion time:
If the nurse is infusing 2000 units/hr and has 25,000 units total, the infusion time will be:
25,000 units / 2000 units/hr = 12.5 hours
Calculate the flow rate in mL/hr:
Total volume of 250 mL needs to be infused over 12.5 hours.
The flow rate is:
250 mL / 12.5 hr = 20 mL/hr

Correct Answer is ["2"]
Explanation
Given:
Prescribed dose: 50 mg of chlordiazepoxide per dose
Available tablets: 25 mg capsules
Steps to solve:
Determine the number of capsules per dose:
Find how many 25 mg capsules are needed to make 50 mg of chlordiazepoxide.
Set up a proportion to solve for the unknown number of capsules (X):
25 mg/capsule = 50 mg/X capsules
Cross-multiplying gives us:
25 mg x X capsules = 50 mg x 1 capsule
Simplifying:
25X = 50
Solving for X:
X = 50 / 25 = 2 capsules
Correct Answer is ["2"]
Explanation
Given:
Prescribed dose: 0.2 mg of desmopressin per dose
Available tablets: 0.1 mg tablets
Steps to solve:
Determine the number of tablets per dose:
Find how many 0.1 mg tablets are needed to make 0.2 mg of desmopressin.
Set up a proportion to solve for the unknown number of tablets (X):
0.1 mg/tablet = 0.2 mg/X tablets
Cross-multiplying gives us:
0.1 mg x X tablets = 0.2 mg x 1 tablet
Simplifying:
0.1X = 0.2
Solving for X:
X = 0.2 / 0.1 = 2 tablets
