What would happen if your patient did not have alpha cells of the pancreas?
They would not be able to secrete insulin.
They would not be able to secrete glucagon.
They would not be able to secrete somatostatin and gastrin.
They would not be able to secrete pancreatic polypeptides.
The Correct Answer is B
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.

Correct Answer is B
Explanation
A. Overactive bladder refers to the condition where there is a sudden and uncontrollable urge to urinate, often associated with urgency and frequency, but it is not caused by exertional stimuli.
B. Stress incontinence is the type of urinary incontinence that occurs when physical activity or exertion, such as coughing, sneezing, laughing, or lifting, increases abdominal pressure and leads to involuntary leakage of urine.
C. Functional incontinence refers to the inability to reach the bathroom in time due to physical or cognitive impairments, such as mobility issues or dementia, rather than exertional triggers.
D. Urge incontinence is the sudden and intense urge to urinate, often leading to involuntary loss of urine. It is not typically caused by exertion but by an overactive bladder.
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.
