What is the onset time for Regular U-500 insulin?

  1. 15 minutes

  2. 1-2 hours

  3. 30 minutes

  4. 3-4 hours

The correct answer is: 30 minutes

Regular U-500 insulin has a onset time of 30 minutes, which means it starts working within 30 minutes after injection. Option A is incorrect because 15 minutes is not enough time for the insulin to begin working. Option B is incorrect because 1-2 hours is too long for the onset time of Regular U-500 insulin. Option D is incorrect because 3-4 hours is even longer than the previous option, making it unlikely for Regular U-500 insulin's onset time.
