Glucose And Carbohydrates Quiz

A 2 HOUR PLASMA GLUCOSE OF 200mg/dL or greater is a criteria used to diagnose diabetes. This means that if a person's blood glucose level is 200mg/dL or higher 2 hours after consuming a glucose drink, it indicates that they have diabetes. This criteria is commonly used in diagnostic tests for diabetes to determine if a person's blood sugar levels are within normal range or if they have the condition. Therefore, the statement is true.

Galactosemia is a rare genetic disorder that affects the body's ability to break down galactose, a sugar found in milk and dairy products. If left undiagnosed and untreated, galactosemia can lead to severe complications and even death. Therefore, early detection is crucial in managing the condition and preventing fatal outcomes.

Glucose is the primary source of energy for cells because it is broken down through a process called cellular respiration, which releases energy in the form of ATP. This energy is then used by cells to perform various functions such as growth, repair, and movement. Oxygen is required for the complete breakdown of glucose, but glucose itself is the molecule that provides the initial energy. Adrenaline and lactose are not primary sources of energy for cells.

Glucose is a simple sugar. Simple sugars, also known as monosaccharides, are the basic building blocks of carbohydrates. Glucose is the primary source of energy for the body's cells and is essential for various physiological processes. It is easily broken down and absorbed by the body, providing a quick source of energy.

Type 1 Diabetes is a condition where the body is unable to produce insulin, a hormone that regulates blood sugar levels. Without insulin, the body cannot effectively convert glucose into energy, leading to high blood sugar levels. This is why insulin is necessary for individuals with Type 1 Diabetes to manage their condition. The absence of glucose or insulin receptors is not the cause of Type 1 Diabetes.

The correct answer is Diabetes Mellitus. The patient's symptoms of thirst, nocturia, and lack of energy, along with a fasting glucose level of 160, are consistent with a diagnosis of Diabetes Mellitus. Diabetes Mellitus is a chronic condition characterized by high blood sugar levels due to the body's inability to produce or use insulin effectively. This can lead to symptoms such as increased thirst, frequent urination, and fatigue. The elevated fasting glucose level confirms the presence of high blood sugar, indicating Diabetes Mellitus.

The correct answer is AMERICAN DIABETES ASSOCIATION. ADA is commonly used as an abbreviation for the American Diabetes Association, which is a non-profit organization that aims to prevent and cure diabetes and improve the lives of all people affected by diabetes.

The statement is true because a 3-hour OGTT (Oral Glucose Tolerance Test) is no longer recommended for diagnosing hypoglycemia due to its adverse effects. The OGTT involves consuming a high amount of glucose and then measuring blood sugar levels at regular intervals. However, this test can cause symptoms of hypoglycemia in individuals with normal blood sugar levels, leading to unnecessary anxiety and potential harm. Therefore, alternative tests, such as continuous glucose monitoring, are now preferred for diagnosing hypoglycemia.

Type 2 diabetes occurs when the insulin receptors in the body are not working properly. Insulin receptors are responsible for allowing cells to take in glucose from the bloodstream. When these receptors are not working effectively, the cells are unable to properly utilize insulin, leading to high blood sugar levels. This is a characteristic feature of type 2 diabetes, where the body becomes resistant to the effects of insulin.

HbA1C is also known as glycated hemoglobin. This term refers to the hemoglobin in the blood that has been bound to glucose. This measurement is used to assess average blood sugar levels over a period of time, typically the past 2 to 3 months. By measuring the amount of glycated hemoglobin in the blood, healthcare professionals can evaluate how well a person's diabetes is being managed.

The given symptoms of excessive thirst, nausea and vomiting, shortness of breath, and fruity-scented breath are indicative of diabetic ketoacidosis (DKA). DKA is a serious complication of diabetes where there is a lack of insulin, leading to high blood sugar levels and the breakdown of fats for energy. This breakdown produces ketones, which can cause a fruity odor in the breath. The combination of symptoms suggests DKA rather than hypoglycemia (low blood sugar), galactosemia (a rare genetic disorder), or diabetes insipidus (a condition affecting water balance).

Gray topped tubes contain a glycolytic inhibitor, such as sodium fluoride or potassium oxalate, which prevents the breakdown of glucose in the blood sample. This is important because glucose can be rapidly metabolized by red blood cells, leading to falsely low glucose levels if the sample is not processed in a timely manner. Therefore, if separation of serum for glucose testing will be delayed, using gray topped tubes with a glycolytic inhibitor can help preserve the accuracy of the glucose measurement.

The correct answer is 4%-5%. Hemoglobin A1C is a test that measures the average blood sugar levels over the past 2-3 months. For a normal non-diabetic patient, the range of Hemoglobin A1C should be between 4% and 5%. This indicates good blood sugar control and a lower risk of developing diabetes. A higher percentage, such as 7% or above, suggests poor blood sugar control and may indicate the presence of diabetes. A range between 8% and 12% is even higher and indicates uncontrolled diabetes.

The given results indicate that the patient's whole blood glucose level is 77mg/dl, serum glucose level is 88 mg/dl, and CSF glucose level is 56 mg/dl. The correct answer states that all values are consistent with a normal healthy individual. This means that the glucose levels in the patient's blood and CSF are within the normal range for a healthy person, indicating that there is no abnormality or underlying health condition related to glucose metabolism.

The correct answer is 7% OR LESS. Hemoglobin A1C is a test that measures the average blood sugar levels over the past 2-3 months. A target of 7% or less indicates good diabetes control. This level is recommended by healthcare professionals to reduce the risk of complications associated with diabetes, such as heart disease, kidney damage, and nerve damage. Maintaining a lower A1C level indicates that blood sugar levels are well-managed and within the target range.

Glucagon, epinephrine, and growth hormone are all hormones that are antagonists to insulin. Insulin is responsible for lowering blood sugar levels, while these hormones work to increase blood sugar levels. Glucagon stimulates the liver to release stored glucose, epinephrine stimulates the breakdown of glycogen into glucose, and growth hormone reduces the uptake and utilization of glucose by cells. Therefore, these hormones counteract the effects of insulin and promote an increase in blood sugar levels. ANP, on the other hand, is not an antagonist to insulin and does not have a direct effect on blood sugar regulation.

The symptoms listed in the answer are all associated with hypoglycemia. Faintness, weakness, hunger, sweating, visual disturbance, and confusion are common symptoms experienced when blood sugar levels drop too low. Seizures, personality changes, and palsy can also occur in severe cases of hypoglycemia. However, symptoms such as coma, intense thirst, ketoacidosis, dry flushed skin, and weak pulse are not typically associated with hypoglycemia and may indicate other medical conditions.
