Metabolic acidosis may be associated with:

A. Drinking 400 ml every hour is not a typical recommendation for bowel preparation with PEG. The client is usually instructed to drink a specific volume, but it is typically more than 400 ml at once and spread over a specific time frame, often 1-2 liters over several hours.

B. Abdominal bloating is a common side effect of polyethylene glycol-electrolyte solutions. The solution works by drawing water into the intestines to induce bowel movements, and this can lead to temporary bloating or discomfort.

C. While it is important to stay hydrated during the bowel prep, the recommendation to drink an additional liter of fluid is not typically included in the instructions. The PEG solution itself is designed to maintain fluid balance, and additional water may be advised, but this is not the standard guideline.

D. Bowel movements typically begin shortly after starting the PEG solution, often within 1-2 hours, rather than waiting 3 hours. The exact timing can vary, but 3 hours is longer than usual for the first bowel movement to occur.

A. While high blood glucose levels can affect nerve function, excessive glucose exposure does not specifically target the brain and spinal cord in a way that causes neuropathy.

B. Neuropathy in diabetes is not caused by the inability to provide glucose to the brain and spinal cord, but rather by the effects of high blood glucose levels on peripheral nerves.

C. Infection in the nerves is not the primary cause of diabetic neuropathy, although infection can occur in diabetic patients due to poor circulation and immune system impairment.

D. Chronic high blood glucose levels can cause thickening of blood vessels, leading to poor circulation (ischemia) that deprives nerves of oxygen and nutrients, ultimately causing nerve damage. This is the primary cause of diabetic neuropathy.
