Insulin & Oral Antidiabetics

Match insulin action to meals and know how to spot and treat hypoglycemia fast.

Key points

• Rapid-acting insulin (lispro) starts in about 15 minutes — give with meals.
• Only regular insulin is given IV.
• Treat hypoglycemia with the rule of 15.
• Metformin is usually held around iodinated contrast because of lactic acidosis risk.

Test-taking tip: Eliminate options that are true but do not answer the question asked.
