A nurse is preparing to administer 50 units of mixed insulin (NPH/Regular 50/50) for a client with type 2 diabetes. How many units of Regular insulin will the client receive per dose? (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 ["25"]
Mixed insulin solution that contains 50/50 ratio of regular and NPH insulin.
For every 100 units of the mixture, 50 units are regular insulin and 50 units are NPH insulin.
Calculating the Regular Insulin Dose:
Since the ratio is 50/50, we can calculate the amount of regular insulin in this 50-unit dose:
Regular insulin dose = Total dose x (Percentage of regular insulin)
Regular insulin dose = 50 units x (50/100)
Regular insulin dose = 50 units x 0.5
Regular insulin dose = 25 units

Correct Answer is ["15"]
Explanation
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 ["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.
