I am a new grad in LTC, still trying to learn about diabetes/insulin...How long does it take for the carbs in a meal to spike. We do accuchecks at 3:30, insulin due at 4:30, dinner comes up at 5:00. I only have 3 diabetics one is on regular/nph and the other two on novolin. If I find thier bs reading very high, should I give the insulin earlier? how do I know when the carbs will spike?how can I become more proficient in diabetes management?
