Step-by-step explanation:
For Leonard, a 72-year-old male with DM 2, a reasonable A1C goal would be between 7% and 8%. The A1C test measures the average blood glucose level over the past 4 months, and a level of less than 7% is considered normal. However, diabetics rarely achieve such levels, so the general target is to come close to it. Keeping the A1C levels close to 7% can significantly reduce the risk of diabetes complications affecting the eyes, kidneys, and nerves, compared to levels of 8% or higher.
