Final answer:
Hypoglycemia symptoms include tremors, sweating, weakness, and fainting. Administration of glucose, either by injection or orally, can quickly relieve these symptoms by raising blood glucose levels to provide energy to the brain. The answer is option 3.
Step-by-step explanation:
Symptoms of Hypoglycemia and Glucose Administration
The symptoms of hypoglycemia, a condition characterized by low blood glucose levels, can vary but often include tremors, sweating, weakness, fainting, and in severe cases, coma and death. The brain is dependent on glucose as its primary energy source, and a lack of glucose can result in these symptoms due to insufficient energy being supplied to the brain.
When hypoglycemia occurs, particularly during situations such as excessive insulin therapy in diabetes mellitus or renal dysfunction, immediate administration of glucose is the primary treatment. This can be done through injecting glucose or by oral consumption of sugar, which quickly increases blood glucose levels and alleviates the symptoms by providing the necessary energy for proper brain function.
In contrast to hypoglycemia, hyperglycemia is a condition of high blood sugar levels, which has its own set of symptoms like frequent urination and glucose presence in urine. It is important to maintain balanced blood glucose levels as both hypoglycemia and hyperglycemia can have detrimental effects on health.
