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 ["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.
Correct Answer is ["650"]
Explanation
Rationale: Step 1 is to convert the client's weight from pounds (lbs) to kilograms (kg) Client weight = 286 lbs Conversion factor = 2.2 lbs per 1 kg Weight in kg = (286 ÷ 2.2) 286 ÷ 2.2 = 130 Weight in kg = 130 kg
Step 2 is to calculate the total dose in milligrams (mg) per dose Prescribed dose = 5 mg/kg Total mg dose = 130 × 5 130 × 5 = 650 Total mg dose = 650 mg
Step 3 is to round to the nearest whole number 650 = 650 Answer: 650
