Which procedure is required for blood glucose levels below 35 mg/dl?

Administering glucagon is the appropriate procedure for blood glucose levels below 35 mg/dl because glucagon is a hormone that stimulates the liver to release stored glucose into the bloodstream. In cases of severe hypoglycemia, particularly when the individual is unable to swallow or is unconscious, glucagon is critical for rapidly increasing blood glucose levels to a safe range. This option is especially vital because it can counteract the risks associated with dangerously low blood sugar levels, preventing complications such as loss of consciousness or seizures.

Other procedures, such as intravenous fluid administration, heel stick testing, or providing oral glucose, may not be suitable in this context. For instance, intravenous fluids would typically be used for hydration rather than directly addressing hypoglycemia. A heel stick for glucose testing would be a method to check glucose levels rather than a response to low levels. Providing oral glucose is effective but can be risky if the patient is unconscious or unable to swallow, as it poses a significant risk of aspiration. Hence, administering glucagon is the proper response in critical hypoglycemic situations.
