Individuals with diabetes are also at increased risk for developing infection due to hyperglycemia related to microvascular, macrovascular, and neuropathic complications due to:

Choice A reason: NGT (nasogastric tube) is used for enteral feeding, not parenteral nutrition. Enteral feeding involves delivering nutrients directly to the stomach or small intestine, bypassing the need for eating. This method is suitable for patients who have a functioning digestive system but cannot eat orally. Parenteral nutrition, on the other hand, involves delivering nutrients directly into the bloodstream.

Choice B reason: Oral administration of nutrition involves consuming food or nutrients by mouth. This method is suitable for individuals who can eat and digest food normally. Parenteral nutrition bypasses the digestive system altogether and delivers nutrients directly into the bloodstream, making oral administration inappropriate for TPN.

Choice C reason: Central Line is the correct answer because Total Parenteral Nutrition (TPN) requires delivery of nutrients directly into a central vein, typically the superior vena cava. This is because TPN solutions are highly concentrated and can irritate smaller veins, leading to complications such as phlebitis. A central line allows for the safe administration of TPN, ensuring that the high osmolarity solution is rapidly diluted by the large volume of blood in the central veins.

Choice D reason: Peripheral line administration is used for Peripheral Parenteral Nutrition (PPN), not TPN. PPN can be delivered through a peripheral vein because it is less concentrated than TPN. Using a peripheral line for TPN is not appropriate due to the risk of complications from the high osmolarity of the TPN solution.

Choice A reason: Alpha cells of the pancreas do not produce insulin. Insulin is produced by the beta cells of the pancreas. Therefore, the absence of alpha cells would not affect insulin secretion.

Choice B reason: The primary function of alpha cells in the pancreas is to produce and secrete glucagon. Glucagon is a hormone that raises blood glucose levels by promoting the conversion of glycogen to glucose in the liver. Without alpha cells, the body would not be able to secrete glucagon, leading to issues with glucose regulation.

Choice C reason: Somatostatin and gastrin are not secreted by alpha cells. Somatostatin is produced by delta cells of the pancreas and other parts of the digestive system, while gastrin is primarily produced by G cells in the stomach lining. Therefore, the absence of alpha cells would not affect the secretion of somatostatin and gastrin.

Choice D reason: Pancreatic polypeptides are produced by PP cells (pancreatic polypeptide cells) in the pancreas. The absence of alpha cells would not impact the secretion of pancreatic polypeptides.
