The nurse is scheduled to administer lispro insulin per sliding scale before meals. The serum blood glucose reading before lunch is 152 mg/dl. Given the following sliding scale, how much insulin lispro should be given before lunch? (Select the appropriate parameter.)
A.
If 60-124, no coverage
B.
If 125-150, give two units
C.
If 251-300, give eight units
D.
If 201-250, give six units
The correct answer and Explanation is :
Given the sliding scale for administering lispro insulin and a serum blood glucose reading of 152 mg/dl before lunch, you would use the following guidelines:
Sliding Scale Guidelines:
- A. If 60-124 mg/dl, no coverage.
- B. If 125-150 mg/dl, give two units.
- C. If 251-300 mg/dl, give eight units.
- D. If 201-250 mg/dl, give six units.
Correct Answer: B. If 125-150 mg/dl, give two units.
Explanation:
- Understanding the Sliding Scale:
The sliding scale for insulin dosing is a tool used to manage blood glucose levels by providing a specific amount of insulin based on the blood glucose reading. It is typically used for patients with diabetes to adjust insulin doses according to current glucose levels. - Evaluating the Blood Glucose Reading:
The serum blood glucose reading before lunch is 152 mg/dl. According to the sliding scale provided:
- For readings between 60-124 mg/dl, no insulin is needed.
- For readings between 125-150 mg/dl, the recommended dose is two units of insulin.
- For readings between 151-200 mg/dl (not specifically listed but inferred), the dose would need to be determined based on additional information not provided here. However, since 152 mg/dl falls within the 125-150 mg/dl range, it is most appropriate to follow the guidance given in option B.
- Why Option B is Correct:
Since the glucose level of 152 mg/dl falls within the 125-150 mg/dl range, the correct dosage of insulin, according to the scale, is two units. This range specifically guides how much insulin should be administered to bring the glucose level back into the target range. - Adjustments and Monitoring:
It’s important to monitor the patient’s blood glucose levels regularly and adjust the insulin dosage as needed based on the glucose readings and the patient’s overall health status. Continuous monitoring and adherence to the prescribed sliding scale are essential for effective diabetes management and maintaining optimal glucose control.
By following the sliding scale carefully, you ensure that the patient receives the appropriate amount of insulin to manage their blood glucose levels effectively.
