What is the difference in stool characteristics between breast fed babies and babies fed with artificial milk or formula?
Breast fed babies have soft, formed, and yellowish-brown stool while babies fed with formula have less frequent stooling patterns, and light brown stool.
Formula fed babies have soft, unformed, and yellow stool while breastfed babies have less frequent stooling patterns, and light brown stool.
Breast fed babies have soft, unformed, and yellow stool while babies fed with formula have less frequent stooling patterns, and light brown stool.
Breast fed babies have soft, unformed, and light brown stool while babies fed with formula have yellow stool.
The Correct Answer is C
Choice A reason: Breastfed babies typically have unformed (rather than formed) stools that are yellow and seedy, not yellowish-brown. Formula-fed babies tend to have more formed stools that are light brown or tan in color. The stooling frequency is often higher in breastfed babies compared to formula-fed babies.
Choice B reason: This description is incorrect. Formula-fed babies typically have more formed stools that can range from light brown to tan, rather than yellow. Breastfed babies usually have yellow, unformed stools and tend to stool more frequently.
Choice C reason: Breastfed babies have soft, unformed, and yellow stools due to the easy digestibility of breast milk. Formula-fed babies tend to have less frequent stooling patterns and their stools are more formed and light brown in color. This difference is due to the different compositions of breast milk and formula.
Choice D reason: Breastfed babies do not usually have light brown stools; their stools are typically yellow and unformed. Formula-fed babies can have yellow stools in some cases, but more commonly, their stools are light brown or tan and more formed.

Correct Answer is A
Explanation
Choice A reason: Type 1 diabetes is characterized by the destruction of pancreatic islet cells (also known as beta cells) that produce insulin. This autoimmune process leads to a severe lack of insulin in the body. Insulin is essential for regulating blood glucose levels, and without it, glucose cannot enter the cells and remains in the bloodstream, leading to hyperglycemia. This destruction of insulin-producing cells is the fundamental defect in type 1 diabetes.
Choice B reason: Resistance of insulin-sensitive tissues to insulin is a characteristic of type 2 diabetes, not type 1 diabetes. In type 2 diabetes, the body's cells become resistant to insulin, and the pancreas may eventually fail to produce enough insulin to overcome this resistance. This leads to elevated blood glucose levels, but the underlying mechanism is different from the autoimmune destruction seen in type 1 diabetes.
Choice C reason: Stimulation by food intake of glucose production resulting in increased insulin production is not a defining feature of type 1 diabetes. While the intake of food does lead to glucose production and a subsequent need for insulin, this mechanism is part of normal physiology and is not specific to any type of diabetes. Type 1 diabetes specifically involves the lack of insulin production due to the destruction of the pancreatic beta cells.
Choice D reason: Decreased production of releasing hormones by the hypothalamus is not related to the pathophysiology of type 1 diabetes. The hypothalamus plays a role in regulating various hormonal processes, but type 1 diabetes is primarily an autoimmune disorder affecting the pancreas. The destruction of insulin-producing beta cells in the pancreas is the key issue in type 1 diabetes.
Correct Answer is C
Explanation
Choice A reason: Both the Somogyi effect and the dawn phenomenon can occur between 4 a.m. and 9 a.m., so this is not a distinguishing factor between the two. They both involve changes in blood glucose levels during this early morning period.
Choice B reason: Both phenomena are influenced by the release of certain hormones, including growth hormone, cortisol, and catecholamines. These hormones can contribute to early morning hyperglycemia, but this alone does not differentiate the Somogyi effect from the dawn phenomenon.
Choice C reason: The Somogyi effect, also known as rebound hyperglycemia, is characterized by a period of hypoglycemia (low blood sugar) that occurs during the night, often as a result of excess insulin or other diabetic treatments. This overnight hypoglycemia triggers a counter-regulatory hormone response that leads to hyperglycemia in the early morning. In contrast, the dawn phenomenon is characterized by hyperglycemia in the early morning without preceding hypoglycemia. The dawn phenomenon is due to the natural overnight release of hormones like growth hormone and cortisol, which cause the liver to release glucose into the blood.
Choice D reason: While both effects involve hormone-mediated changes in glucose metabolism, the key difference lies in the presence or absence of preceding hypoglycemia. The dawn phenomenon does not involve insulin resistance triggered by overnight hypoglycemia, whereas the Somogyi effect does. The distinction primarily lies in the nocturnal blood sugar patterns and the body's response to them.
