Final answer:
In cases of hypoglycemia, a patient weighing 25kg or more would be treated with a glucagon injection at a dose of 30 µg/kg body weight, followed by careful monitoring of their blood glucose levels to assess the response.
Step-by-step explanation:
Glucagon is a vital hormone that regulates blood glucose levels, particularly during instances of hypoglycemia when blood sugar is abnormally low. For a patient weighing 25kg or greater, the treatment plan under the Hypoglycemia Medical Directive would likely involve administering an appropriate dose of glucagon to increase blood glucose. This dose is typically given intravenously at 30 µg per kg of the patient's body weight. The patient's blood glucose levels are then monitored regularly to assess the response to treatment. In addition to its immediate effects, observing how blood glucose levels change after a glucagon injection can help in understanding whether diabetes mellitus is due to excessive insulin antagonists or alterations in insulin receptors or responses.
