Medications for diarrhea that work by absorbing excess fluid in fecal matter in the colon without affecting transport processes across the membrane are known as?

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. Oxygen does play a role in maintaining acid-base balance indirectly, as it is required for aerobic metabolism, which produces carbon dioxide that is regulated by the body to maintain acid-base balance. However, this is not its primary role.

B. Oxygen does trigger chemoreceptors, but this is more of a secondary function to regulate breathing based on oxygen and carbon dioxide levels.

C. While oxygen has many roles, its most critical function is providing the necessary support for cellular metabolism, which is vital for energy production in cells.

D. Oxygen is essential for cellular metabolism as it is required for the process of oxidative phosphorylation in mitochondria, which produces ATP, the energy currency of cells.
