What is glucose reading like with the Dawn Phenomenon?
One triggers insulin resistance and the release of glucose from the liver.
One is caused by the release of certain hormones.
Occurs between 4 a.m. and 9 a.m with hyperglycemia.
One is characterized by hyperglycemia that is not triggered by overnight hypoglycemia.
The Correct Answer is D
Choice A reason: This statement is partially correct but does not fully address the question about glucose readings. The Dawn Phenomenon involves an increase in blood glucose levels in the early morning due to the release of counter-regulatory hormones (like cortisol and growth hormone) that increase insulin resistance and stimulate glucose release from the liver.
Choice B reason: This statement is true but incomplete. The Dawn Phenomenon is indeed caused by the release of certain hormones, but this option does not specify the timing or the glucose readings.
Choice C reason: While the hyperglycemia associated with the Dawn Phenomenon does typically occur between 4 a.m. and 9 a.m., this option does not fully describe the nature of the glucose readings. It is more important to note that the hyperglycemia is not due to overnight hypoglycemia.
Choice D reason: This statement accurately describes the Dawn Phenomenon. It is characterized by morning hyperglycemia that is not caused by overnight hypoglycemia. Instead, it is due to the body's natural release of counter-regulatory hormones, which increase blood glucose levels during the early morning hours.

Correct Answer is A
Explanation
Choice A reason: Neuropathy, particularly diabetic neuropathy, is often caused by the thickening, sclerosis (hardening), obstruction, and ischemia (reduced blood flow) of the small blood vessels that supply the nerves (vasa nervorum). This can lead to nerve degeneration, delayed nerve conduction, and impaired sensory function. Over time, high blood glucose levels can damage these small blood vessels, leading to neuropathy.
Choice B reason: While hyperglycemia (high blood glucose levels) is a major factor in the development of diabetic neuropathy, it is the resulting damage to the blood vessels supplying the nerves that directly causes the nerve degeneration and delayed conduction.
Choice C reason: Thickening of blood is not a direct cause of neuropathy. Neuropathy is more directly related to the damage and obstruction of the small blood vessels that supply the nerves.
Choice D reason: Hypoglycemia (low blood glucose levels) does not cause neuropathy. In fact, the acute effects of hypoglycemia are typically neurological symptoms such as confusion, seizures, and loss of consciousness. Chronic nerve damage, as seen in neuropathy, is usually due to prolonged hyperglycemia and its effects on blood vessels.
Correct Answer is A
Explanation
Choice A reason: Identification of a significant amount of protein in the urine (proteinuria) is an abnormal finding that can indicate underlying kidney problems. Proteinuria can be a sign of kidney disease, as the kidneys normally prevent large amounts of protein from entering the urine. When protein is detected in the urine, it suggests that the kidneys' filtering mechanism may be damaged. This condition requires further clinical assessment to determine the underlying cause and appropriate treatment.
Choice B reason: It is incorrect to assume that proteinuria will resolve itself without intervention. While some causes of proteinuria, such as temporary increases due to fever or intense physical activity, may be benign and resolve on their own, persistent or significant proteinuria is often indicative of a more serious underlying condition. Ignoring the presence of protein in the urine without further investigation could lead to worsening kidney function or other complications.
Choice C reason: While staying hydrated by drinking 1-2 liters of water per day is generally good advice for overall health, it is not a specific solution for proteinuria. Proper hydration can help maintain kidney function, but it does not address the underlying cause of protein in the urine. Clinical assessment and targeted treatment are necessary to manage proteinuria effectively.
Choice D reason: Dismissing proteinuria as nothing to be worried about is not appropriate. Significant protein in the urine is a clinical finding that warrants further investigation. It could be a sign of kidney disease, diabetes, hypertension, or other health issues that require medical attention. Early diagnosis and management are crucial to prevent potential complications and preserve kidney health.
