Insulin pumps deliver insulin in which manner?

• A. Only during sleep
• B. Continuously and in response to meals
• C. Only during physical activity
• D. Once a day at the same time

Answer: (B)

Insulin pumps deliver insulin continuously throughout the day and can also provide additional doses in response to meals. This continuous delivery helps to maintain stable blood glucose levels, mimicking the way a healthy pancreas releases insulin. The pump is programmed to release a steady basal rate of insulin at all times and can be adjusted to deliver a bolus of insulin when food is consumed, addressing the post-meal increases in blood sugar levels. This method offers flexibility and better glycemic control compared to other methods of insulin delivery. The other options suggest more limited or conditional delivery schedules, which do not reflect the typical operation of an insulin pump.
