The diabetic ketoacidosis associated with insulin deficiency is related to:
Extracellular hyperglycemia
Hypoglycemia
Use of fat and protein as an energy source
Increased cellular metabolism of glucose
The Correct Answer is C
Choice A reason:
Extracellular hyperglycemia refers to high blood sugar levels outside the cells. While hyperglycemia is a common feature of diabetic ketoacidosis (DKA), it is not the direct cause of the condition. DKA occurs when the body cannot use glucose for energy due to a lack of insulin, leading to the breakdown of fat and protein for energy, which produces ketones and causes acidosis.
Choice B Reason:
Hypoglycemia, or low blood sugar, is not associated with diabetic ketoacidosis. In fact, DKA is characterized by high blood sugar levels. Hypoglycemia is a separate condition that can occur in individuals with diabetes, particularly if they take too much insulin or skip meals.
Choice C Reason:
The use of fat and protein as an energy source is the primary mechanism behind diabetic ketoacidosis. When insulin is deficient, the body cannot utilize glucose for energy. As a result, it breaks down fat and protein to produce energy. This process generates ketones, which are acidic and lead to the development of ketoacidosis.
Choice D Reason:
Increased cellular metabolism of glucose is not related to diabetic ketoacidosis. In DKA, the problem is that cells cannot use glucose effectively due to a lack of insulin. Instead, the body resorts to breaking down fat and protein for energy, leading to the production of ketones and acidosis.

Correct Answer is B
Explanation
Choice A reason:
Bacteriuria, or the presence of bacteria in the urine, is not typically associated with acute glomerulonephritis. Acute glomerulonephritis is primarily an inflammatory condition affecting the glomeruli of the kidneys, and it does not usually involve bacterial infection. Increased specific gravity can occur due to concentrated urine, but bacteriuria is not a characteristic finding.
Choice B reason:
Hematuria, or blood in the urine, and mild to moderate proteinuria are characteristic findings in acute glomerulonephritis. Hematuria occurs due to inflammation and damage to the glomeruli, allowing red blood cells to pass into the urine. Proteinuria results from the increased permeability of the glomerular basement membrane, allowing proteins to leak into the urine. These findings are key indicators of glomerular inflammation and damage.
Choice C reason:
While proteinuria can be present in acute glomerulonephritis, bacteriuria is not a typical finding. The condition is primarily inflammatory rather than infectious, so the presence of bacteria in the urine is not expected. The focus should be on the inflammatory markers such as hematuria and proteinuria.
Choice D reason:
High levels of proteinuria and decreased specific gravity are not typical findings in acute glomerulonephritis. While proteinuria can occur, it is usually mild to moderate rather than high. Specific gravity may be increased due to concentrated urine, but decreased specific gravity is not a characteristic finding of this condition.
Correct Answer is C
Explanation
Choice A reason:
Extra insulin is not typically required during exercise for children with type 1 diabetes. In fact, exercise can lower blood glucose levels, and administering extra insulin could increase the risk of hypoglycemia. It is important to monitor blood glucose levels before, during, and after exercise to adjust insulin doses as needed, but extra insulin is generally not necessary.
Choice B reason:
Exercise usually lowers blood glucose levels rather than increasing them1. Physical activity helps the body use glucose more efficiently, which can lead to a decrease in blood glucose levels. However, it is important to monitor blood glucose levels closely, as some high-intensity exercises can cause temporary increases in blood glucose due to the release of stress hormones.
Choice C reason:
Extra snacks are needed before exercise to prevent hypoglycemia in children with type 1 diabetes. Consuming a carbohydrate snack before physical activity helps maintain stable blood glucose levels during exercise. The amount of carbohydrates needed can vary based on the intensity and duration of the exercise, so it is important to monitor blood glucose levels and adjust snack intake accordingly.
Choice D reason:
Exercise should not be restricted for children with type 1 diabetes. Regular physical activity is important for overall health and can help improve insulin sensitivity, cardiovascular health, and overall well-being. With proper planning and monitoring, children with type 1 diabetes can safely participate in a wide range of physical activities.
