Final answer:
Insulin is a high-alert medication due to its potent effects on blood glucose levels, where errors in its use can cause serious harm. It's essential for managing diabetes, particularly type 1, and insulin sensitivity can be determined through an insulin tolerance test.
Step-by-step explanation:
Insulin as a High-Alert Medication
Insulin is considered a high-alert medication primarily because it is a potent drug that can cause significant harm when used in error. Given its critical role in regulating blood glucose levels, any mistake in dosage or administration can lead to serious consequences, including hypoglycemia (low blood sugar) or hyperglycemia (high blood sugar). People with type 1 diabetes rely on insulin injections to manage their blood sugar levels, especially after consuming a meal high in glucose. Insulin allows for the transport and storage of glucose to decrease blood glucose levels post-meal, by promoting its absorption into the liver, fat, and muscle cells, and converting it into glycogen or fats.
For those with diabetes, particularly type 1 diabetes, insulin shots are a lifelong necessity. Self-administration of insulin is a common practice and crucial for survival. An insulin tolerance test can determine if a person's diabetes is responsive to insulin treatment. The test involves measuring blood glucose levels after administering insulin, and observing the decrease in glucose levels to assess insulin sensitivity.
