A client with rheumatoid arthritis and psoriasis has been prescribed adalimumab, a biologic agent that blocks tumor necrosis factor alpha (TNF-alpha). Which of the following statements by the client indicates a need for further teaching?

Choice A reason: Half-normal saline solution is a hypotonic solution, which means it has a lower concentration of solutes than the blood plasma. It can cause fluid to shift from the blood vessels into the cells, leading to cellular swelling and edema.

Choice B reason: 10% dextrose in water is a hypertonic solution, which means it has a higher concentration of solutes than the blood plasma. It can cause fluid to shift from the cells into the blood vessels, leading to cellular shrinkage and dehydration.

Choice C reason: 5% dextrose and half-normal saline solution is a hypertonic solution, which has the same effects as choice B. The dextrose increases the osmolarity of the solution, while the half-normal saline provides some electrolytes.

Choice D reason: Lactated Ringer's solution is an isotonic solution, which means it has the same concentration of solutes as the blood plasma. It maintains fluid balance and provides electrolytes such as sodium, potassium, calcium, and lactate. It is commonly used for fluid resuscitation, dehydration, and acidosis.

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.
