Physical examination and change in body weight are used to diagnose ascites, what other measurement is used?

Choice A reason: Reversible deviant cells do not accurately describe neoplasia. Neoplasia involves the uncontrolled and irreversible growth of abnormal cells. While some deviant cell changes can be reversible, neoplasia specifically refers to irreversible changes that lead to tumor formation.

Choice B reason: Neoplasia does not adhere to the genetic controls placed on cellular proliferation and differentiation. In fact, the hallmark of neoplasia is the loss of these regulatory mechanisms, leading to uncontrolled cell growth and differentiation.

Choice C reason: Neoplasia indeed alters cellular proliferation and differentiation. This alteration is due to genetic mutations and other changes that lead to the loss of normal growth control. The result is the formation of tumors, which can be benign or malignant.

Choice D reason: Controlled and regulated cells do not describe neoplasia. Neoplastic cells grow and proliferate without the normal regulatory signals that control cell growth and differentiation. This uncontrolled growth is what characterizes neoplasia.

Choice A reason: Oral hypoglycemic drugs are not used as insulin replacements. Insulin replacement is usually achieved through the administration of insulin injections or insulin pumps. These devices deliver the hormone directly into the body to help regulate blood sugar levels, especially in individuals with type 1 diabetes or severe type 2 diabetes where insulin production is significantly impaired. Oral hypoglycemic drugs, on the other hand, work by different mechanisms and are primarily used for type 2 diabetes management.

Choice B reason: Many oral hypoglycemic drugs, such as metformin and thiazolidinediones, work by reducing insulin resistance. Insulin resistance is a condition where the body's cells do not respond effectively to insulin, leading to elevated blood sugar levels. By improving the body's sensitivity to insulin, these drugs help lower blood sugar levels and improve glucose uptake by the cells. This mechanism is crucial for managing type 2 diabetes, where insulin resistance is a significant issue.

Choice C reason: Some oral hypoglycemic drugs, like metformin, do help in reducing glucose production by the liver. However, saying that these drugs "prevent" the formation of glucose is not entirely accurate. These drugs can inhibit gluconeogenesis, the process by which the liver produces glucose, thereby helping to lower blood sugar levels. However, this is only one aspect of their action, and they are not solely classified based on this mechanism.

Choice D reason: Decreasing the body's need for glucose in body cells is not a primary action of oral hypoglycemic drugs. These medications aim to regulate blood glucose levels by improving insulin sensitivity, reducing glucose production in the liver, and sometimes increasing insulin secretion by the pancreas. The goal is to ensure that glucose is effectively utilized by the body's cells and that blood sugar levels are kept within a healthy range.
