NP125 Med Surg Exam | Nurselytic

Correct Answer: A

Rationale: Insulin glargine (Lantus) is a long-acting insulin used for basal glycemic control in diabetic patients. It has a slow onset and a steady release over approximately 24 hours, mimicking natural insulin secretion to stabilize blood glucose levels and prevent fluctuations. Rapid-acting insulins, such as insulin lispro or aspart, have fast onsets and short durations to manage postprandial glucose spikes. Insulin glargine does not have these properties, as it is used for long-term basal control rather than immediate blood sugar regulation. Intermediate-acting insulins like NPH have a shorter duration and peak effect compared to long-acting insulins. Insulin glargine provides a consistent effect over 24 hours, distinguishing it from intermediate-acting options. Short-acting insulins are designed for pre-meal blood sugar control with a quick onset and limited duration. Insulin glargine does not fit this description due to its long-acting properties.
