Which is not a requirement for effective perfusion?
Absence of chronic disease
Adequate blood volume
An open airway
Functional systemic circulation
The Correct Answer is A
A. The absence of chronic disease is not a strict requirement for effective perfusion. While chronic diseases can impact perfusion, such as through the effects of diabetes or hypertension on the cardiovascular system, effective perfusion can still occur in individuals with chronic conditions if other factors are managed appropriately.
B. Adequate blood volume is essential for effective perfusion because without enough blood, oxygen and nutrients cannot be delivered to tissues.
C. An open airway is crucial for effective perfusion because it allows for proper oxygenation, which is necessary for the delivery of oxygen to tissues via the bloodstream.
D. Functional systemic circulation is required for effective perfusion, as it ensures that blood can flow throughout the body to deliver oxygen and nutrients to tissues and remove waste products.

Correct Answer is A
Explanation
A. Hyperglycemic hyperosmolar-nonketotic syndrome (HHNS) is more commonly associated with type 2 diabetes. It is characterized by very high blood sugar levels and dehydration, but without significant ketone production. It typically occurs in older adults with type 2 diabetes who experience severe dehydration and illness.
B. Hypoglycemia is more commonly associated with type 1 diabetes due to the frequent need for insulin therapy, which can cause low blood sugar levels. In type 2 diabetes, hypoglycemia is less common unless the patient is on insulin or certain oral medications.
C. Diabetic ketoacidosis (DKA) is primarily a complication of type 1 diabetes. It occurs when there is a severe insulin deficiency, leading to the breakdown of fat for energy and the production of ketones. While DKA can occur in type 2 diabetes, it is far more common in type 1.
D. The Somogyi effect refers to rebound hyperglycemia following an episode of hypoglycemia, typically occurring overnight. It is more commonly seen in type 1 diabetes, especially when insulin doses are too high, causing low blood sugar at night followed by a rebound increase in blood sugar.
Correct Answer is B
Explanation
A. Insulin is secreted by beta cells of the pancreas, not alpha cells. Therefore, a lack of alpha cells would not affect insulin secretion.
B. Alpha cells of the pancreas are responsible for secreting glucagon, which helps raise blood glucose levels by promoting the release of glucose from the liver. Without alpha cells, glucagon secretion would be impaired.
C. Somatostatin and gastrin are secreted by delta cells and G cells, respectively, not alpha cells. Therefore, a lack of alpha cells would not prevent the secretion of these hormones.
D. Pancreatic polypeptides are secreted by F cells in the pancreas, not alpha cells. Therefore, a lack of alpha cells would not affect the secretion of pancreatic polypeptides.
