Accepted Answer

Erika's blood glucose level is high and needs to be lowered to avoid complications. As she has type 1 diabetes, she needs to give herself a specific dose of insulin to lower her blood glucose level. Option A is incorrect because a blood glucose level of 260 mg/dl is high and not normal. Option C is incorrect because taking a dietary supplement containing vitamins will not help lower her blood glucose level. Option D is incorrect because consuming candy or fruit juice will increase her blood glucose level, which is not what she wants to do in this case.

Accepted Answer

A blood glucose level of 60 mg/dl is considered low and can cause symptoms such as shakiness, sweating, and dizziness. Consuming candy or fruit juice can quickly raise blood glucose levels and prevent these symptoms from worsening. Waiting for the blood glucose level to drop to normal naturally or giving an extra injection of insulin can cause further harm to the body.
