A nurse is preparing to infuse 6 units/hr of regular Insulin for a client with diabetic ketoacidosis (DKA). The amount available is 100 unit in a 100 ml bag of 0.9 sodium chloride. How will the nurse set up the flow rate mL/hrl? (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 ["6"]
Given:
Total units of insulin: 100 units
Total volume: 100 mL
Desired infusion rate: 6 units/hr
Steps to solve:
Determine the infusion time:
If the nurse is infusing 6 units/hr and has 100 units total, the infusion time will be:
100 units / 6 units/hr = 16.67 hours (approximately 17 hours)
Calculate the flow rate in mL/hr:
Total volume of 100 mL needs to be infused over 17 hours.
The flow rate is:
100 mL / 17 hr = 5.88 mL/hr
Round to the nearest whole number:
6 mL/hr.

Correct Answer is ["100"]
Explanation
Given:
Total volume: 200 mL
Time: 2 hours
Steps to solve:
Determine the flow rate:
Set up a proportion to solve for the unknown flow rate (X):
200 mL/2 hr = X mL/1 hr
Cross-multiplying gives us:
200 mL x 1 hr = 2 hr x X mL
Simplifying:
200 = 2X
Solving for X:
X = 200 / 2 = 100 mL/hr
Correct Answer is ["0.5"]
Explanation
Given:
Prescribed dose: 25 mg of atenolol per dose
Available tablets: 50 mg tablets
Steps to solve:
Determine the number of tablets per dose:
Find how many 50 mg tablets are needed to make 25 mg of atenolol.
Set up a proportion to solve for the unknown number of tablets (X):
50 mg/tablet = 25 mg/X tablets
Cross-multiplying gives us:
50 mg x X tablets = 25 mg x 1 tablet
Simplifying:
50X = 25
Solving for X:
X = 25 / 50 = 0.5 tablets
