Which of the following is a potential side effect of glucagon?

The potential side effect of glucagon that is most commonly recognized is hyperglycemia. Glucagon is a hormone that raises blood glucose levels by stimulating the liver to release stored glucose. This mechanism is particularly beneficial in treating hypoglycemia, as it helps restore normal blood sugar levels.

When glucagon is administered, the rapid increase in blood glucose can lead to hyperglycemia, especially if the patient has an underlying condition such as diabetes. This can occur particularly if glucagon is administered without adequate food intake following, or if there is a significant delay in glucose utilization by the body.

While hypotension, increased heart rate, and profuse sweating are possible physiological responses related to other conditions or medications, they are not typically direct side effects of glucagon itself. Hypotension might occur in a broader patient context involving shock or other metabolic derangements but is not a noted side effect of glucagon. Increased heart rate may result from the body's response to elevated blood sugar or anxiety rather than directly from glucagon administration. Profuse sweating can also occur due to hypoglycemia or stress but does not indicate a direct effect of glucagon. Thus, hyperglycemia stands out as the primary concern with glucagon usage.
