A nurse is preparing to infuse 10 units/hr of regular insulin for a client with diabetic ketoacidosis (DKA). The amount available is 100 units in a 150 mL bag of 0.9 sodium chloride. How will the nurse set up the flow rate (mL/hr)? (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 ["15"]
Given:
Total units of insulin: 100 units
Total volume: 150 mL
Desired infusion rate: 10 units/hr
Determine the infusion time:
If the nurse is infusing 10 units/hr and has 100 units total, the infusion time will be:
100 units / 10 units/hr = 10 hours
Calculate the flow rate in mL/hr:
Total volume of 150 mL needs to be infused over 10 hours.
The flow rate is:
150 mL / 10 hr = 15 mL/hr

Correct Answer is ["27"]
Explanation
Given:
Prescribed dose: 720 mcg/kg/hr
Client weight: 132 lbs
Total volume: 250 mL
Total dopamine: 400 mg
Steps to solve:
Convert weight to kg:
1 lb= 0.453592 kg.
Multiply: 132 lbs x 0.453592 kg/lb = 59.9 kg (rounded to one decimal place)
Calculate the total dopamine dose per hour:
Total dose/hr = 720 mcg/kg/hr x 59.9 kg = 43128 mcg/hr = 43.128 mg/hr
Calculate the infusion rate in mL/hr:
Find how many mL of the solution contains 43.128 mg of dopamine.
Set up a proportion to solve for the unknown volume (X):
400 mg/250 mL = 43.128 mg/X mL
Cross-multiplying gives us:
400 mg x X mL = 43.128 mg x 250 mL
Simplifying:
400X = 10782
Solving for X:
X = 10782 / 400 = 26.955 mL/hr
Round off:
27 mL/hr
Correct Answer is ["2"]
Explanation
We are given a sliding scale for insulin aspart dosing based on the client's blood glucose level.
The client's current blood glucose level is 151 mg/dL.
Consulting the Sliding Scale:
The sliding scale provides a range of blood glucose levels and corresponding insulin doses.
We need to find the range that includes the client's blood glucose level of 151.
Applying the Sliding Scale:
Looking at the sliding scale, we can see that the range of 150-199 mg/dL corresponds to a dose of 2 units of insulin aspart.
