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 A
Explanation
A. Dyspnea is the medical term for shortness of breath or difficulty breathing. It is a subjective sensation of uncomfortable breathing and is the most appropriate term for this client's description.
B. Aspiration refers to the inhalation of food, liquid, or other foreign substances into the airways, which can lead to choking or pneumonia. This does not describe the sensation of shortness of breath.

D. Orthopnea is shortness of breath that occurs when lying flat, often associated with heart failure. The description in the question does not specifically mention difficulty breathing while lying down.
Correct Answer is C
Explanation
A. Anti-inflammatory drugs do not primarily work by increasing blood flow to the tissues. While some may have vasodilatory effects, their primary function is to reduce inflammation.
B. Anti-inflammatory drugs do not directly decrease scar formation. They reduce inflammation, which may indirectly help prevent excessive scarring in tissues affected by chronic inflammation, but this is not their primary action.
C. The main action of anti-inflammatory drugs, such as nonsteroidal anti-inflammatory drugs (NSAIDs) or corticosteroids, is to block the chemical mediators of inflammation, such as prostaglandins. This reduces pain, swelling, and other symptoms of inflammation.
D. Anti-inflammatory drugs do not directly enhance the body's immune system. In fact, some, like corticosteroids, may suppress immune responses to reduce inflammation.
