The nurse is providing care for a client with a fluid imbalance. The nurse explains that in the body, areas with high concentration of solutes naturally and passively shift to areas of lower concentration. The nurse is describing which process?

Choice A reason: This statement is not the best response for the nurse to give. The surgeon will not encourage the client to limit their fat intake after an appendectomy, as this has nothing to do with the appendix. The appendix is a small pouch attached to the beginning of the large intestine, not the small intestine where most of the fat digestion and absorption occurs.

Choice B reason: This statement is not the best response for the nurse to give. The appendix does play a role in the immune system and the gut microbiome, as it contains lymphoid tissue and beneficial bacteria. The client may notice some changes in their immunity or digestion after an appendectomy, especially if they have an infection or take antibiotics.

Choice C reason: This statement is not the best response for the nurse to give. The appendix does not affect the absorption of nutrients from the food the client eats, as it is not involved in the digestive process. The appendix is located at the end of the small intestine, where most of the nutrients have already been absorbed.

Choice D reason: This statement is the best response for the nurse to give. The appendix is not essential for survival, and the small intestine can adapt to its removal over time. The client may experience some temporary symptoms such as diarrhea, bloating, or gas after an appendectomy, but these usually resolve within a few weeks. The nurse should reassure the client that they can live a normal and healthy life without an appendix.

Choice A reason: This is not a correct statement because these medications do not coat the ulcer. They are not antacids or mucosal protectants, which can form a protective layer over the ulcer and neutralize the stomach acid.

Choice B reason: This is not a correct statement because these medications do not stop the acid production. They only reduce it by inhibiting the proton pump, which is responsible for secreting acid into the stomach.

Choice C reason: This is not a correct statement because these medications should be taken as prescribed, not as needed. They are not analgesics or anti-inflammatory drugs, which can relieve the pain and inflammation of the ulcer.

Choice D reason: This is a correct statement because these medications have two effects: they kill the bacteria that cause the infection and inflammation of the ulcer, and they reduce the acid production that aggravates the ulcer. This can help heal the ulcer and prevent complications.
