Final answer:
Kim should immediately consume a carbohydrate-rich snack to raise her blood sugar levels and attempt another blood glucose test. If she's unable to test her blood sugar or starts to feel unwell, she should seek medical help.
Step-by-step explanation:
Given that Kim inadvertently injected herself with a significantly larger dose of short-acting insulin than prescribed, it is imperative to take immediate steps to prevent hypoglycemia, a dangerous drop in blood glucose. The inability to check her blood glucose is concerning, but because she feels fine for now, there is time to take preventive action. She should consume a carbohydrate-rich snack or glucose tablet to temporarily raise her blood sugar levels.
Following this, she should attempt another blood glucose test using her meter to ensure she maintains safe glycemic levels. If Kim is unable to test her blood glucose or if she starts to feel unwell, she should seek medical help immediately.
