Final answer:
Insulin is considered a priority in a situation where a patient refuses treatment for elevated blood glucose levels because it prevents life-threatening ketoacidosis. So, the correct answer is option b) It prevents life-threatening ketoacidosis.
Step-by-step explanation:
Insulin is considered a priority in a situation where a patient refuses treatment for elevated blood glucose levels because it prevents life-threatening ketoacidosis.
When blood glucose levels are high and insulin is not available, the body can enter a state of ketoacidosis, where it starts breaking down fat for energy.
This process produces acidic ketones that can lead to organ damage and even death. Insulin helps regulate blood glucose levels and prevents the onset of ketoacidosis, making it crucial for the patient's well-being.
So, the correct answer is option b) It prevents life-threatening ketoacidosis.
