Which statement best describes the comparison of basal-bolus insulin therapy with sliding-scale insulin therapy, including a nursing consideration for each?

• A. Basal-bolus uses a fixed basal insulin dose and meal-time boluses; Sliding-scale uses rapid-acting insulin based on current glucose
• B. Basal-bolus uses a long-acting basal insulin with rapid-acting boluses for meals; nursing: adjust for meals; Sliding-scale uses rapid-acting insulin based on current glucose with no fixed basal; nursing: risk of hyperglycemia and frequent dosing, requires strict protocol
• C. Basal-bolus uses fixed doses regardless of meals; Sliding-scale uses long-acting insulin
• D. Basal-bolus provides continuous infusion with basal and bolus dosing; Sliding-scale is never used

Answer: (B)

The key idea is that basal-bolus therapy aims to mimic normal insulin secretion by providing a steady background insulin plus separate insulin doses at meals to cover carbohydrate intake. A long-acting basal insulin keeps glucose from rising between meals and overnight, while rapid-acting insulin given at mealtimes handles the glucose that comes from eating. This approach requires careful planning around meals, including carbohydrate counting and timing of boluses to match intake, and it necessitates ongoing monitoring for hypoglycemia as doses are adjusted for activity, illness, or changes in appetite. Nursing considerations reflect this proactive, meal-related structure. The basal dose must be set to meet the patient’s baseline needs and continuously monitored for signs of under- or over-treatment, with adjustments made for age, renal function, infection, and other factors. Mealtime boluses require coordination with actual meals and carbohydrate content, and nurses must verify timing and dosing to keep postprandial glucose in target ranges. Sliding-scale insulin therapy, in contrast, uses rapid-acting insulin in response to current glucose readings and does not provide a fixed basal dose. It is reactive, meaning dosing occurs after hyperglycemia has been detected, which can lead to more glycemic variability and gaps in coverage between meals. The nursing approach here centers on strict protocol adherence, frequent glucose checks, timely dosing based on measurements, and vigilant documentation to prevent delays or under-dosing. There is a higher risk of repeated hyperglycemia if doses aren’t given promptly, and a greater chance of hypoglycemia if thresholds aren’t managed carefully. Thus, the statement that correctly describes the comparison is that basal-bolus uses a long-acting basal insulin with rapid-acting boluses for meals, with nursing care focusing on meal-adjusted dosing; sliding-scale uses rapid-acting insulin based on current glucose with no fixed basal, with nursing care emphasizing risk of hyperglycemia and the need for strict protocol and frequent monitoring.
