How is the concentration of Regular U-500 insulin compared to U-100 insulin?

  1. 10 times more concentrated

  2. 5 times more concentrated

  3. Twice as concentrated

  4. The same concentration

The correct answer is: 5 times more concentrated

U-500 insulin is five times more concentrated than U-100 insulin. This means that one milliliter of U-500 insulin contains more insulin compared to one milliliter of U-100 insulin. Option A is incorrect because 10 times more concentrated would mean that one milliliter of U-500 insulin contains 10 times more insulin than one milliliter of U-100 insulin, which is not the case. Option C is incorrect because twice as concentrated would mean that one milliliter of U-500 insulin contains two times more insulin than one milliliter of U-100 insulin, which is also not the case. Option D is incorrect because U-500 insulin is not the same concentration as U-100 insulin.
