The release of insulin is caused by:
Increased lipid breakdown
Decreased blood glucose level
Increased protein breakdown
Increased blood glucose level
The Correct Answer is D
Choice A reason: Increased lipid breakdown does not directly cause the release of insulin. Insulin is a hormone that facilitates glucose uptake by cells and helps regulate blood sugar levels. Lipid metabolism is primarily regulated by other mechanisms and hormones, such as glucagon and epinephrine.
Choice B reason: Decreased blood glucose level would not stimulate insulin release. In fact, low blood glucose levels would signal the pancreas to reduce insulin secretion. Instead, glucagon would be released to increase blood glucose levels by stimulating the conversion of glycogen to glucose in the liver.
Choice C reason: Increased protein breakdown does not directly trigger the release of insulin. Protein metabolism involves amino acids and other metabolic pathways, but insulin release is primarily regulated by blood glucose levels.
Choice D reason: The release of insulin is caused by increased blood glucose levels. When blood glucose levels rise, such as after eating a meal, the beta cells in the pancreas secrete insulin to help cells absorb glucose from the bloodstream, thereby lowering blood glucose levels and maintaining homeostasis.

Correct Answer is C
Explanation
Choice A reason: Swelling of the feet, or peripheral edema, can be associated with ascites, but it is not a primary measurement used to diagnose ascites. Peripheral edema can occur due to various conditions, including heart failure, kidney disease, and venous insufficiency. It does not specifically indicate the presence of ascites, which is the accumulation of fluid in the abdominal cavity.
Choice B reason: Urine output is an important measure of renal function and fluid balance but is not directly used to diagnose ascites. Changes in urine output can indicate kidney function and fluid status but do not specifically assess fluid accumulation in the abdomen.
Choice C reason: Abdominal girth measurement is a key method used to assess and monitor ascites. Measuring the circumference of the abdomen can help quantify the amount of fluid accumulation. An increase in abdominal girth over time is a strong indicator of ascites and can be used to track the progression or resolution of the condition. This method is simple, non-invasive, and effective in evaluating the severity of ascites.
Choice D reason: Chest circumference is not used to diagnose ascites. While changes in chest circumference can indicate respiratory or thoracic conditions, they do not provide information about fluid accumulation in the abdominal cavity. Ascites is specifically related to the abdomen, and measurements of abdominal girth are more relevant and informative in this context.
Correct Answer is C
Explanation
Choice A reason: Cirrhosis is a condition that affects the liver, not the kidneys. It is not related to nephropathy, which is kidney disease.
Choice B reason: Cardiac disease, while a common complication of diabetes, is not directly caused by nephropathy. Nephropathy primarily affects the kidneys and can lead to kidney failure, but it is not the leading cause of cardiac disease.
Choice C reason: Nephropathy in individuals with diabetes can lead to end-stage kidney disease (ESRD), also known as end-stage renal disease. This is a serious condition where the kidneys are no longer able to function adequately to maintain life, often requiring dialysis or a kidney transplant.
Choice D reason: Pulmonary disease affects the lungs and is not directly related to nephropathy. While diabetes can have complications that affect the lungs, nephropathy specifically targets the kidneys.
