Correct Answer: C

Rationale: The correct answer is C: Fat. Excessive ingestion of fat has been linked to autoimmunity due to its potential to trigger inflammation in the body, which can disrupt the immune system's balance and lead to autoimmune responses. High-fat diets have been associated with increased production of pro-inflammatory molecules, impacting immune function negatively. Protein (choice A) is essential for immune function, vitamin A (choice B) supports immune responses, and zinc (choice D) is crucial for immune system regulation. However, excessive intake of these nutrients typically does not directly lead to autoimmunity like excessive fat consumption does.

Correct Answer: C

Rationale: The correct answer is C: Cheese. Cheese is high in sodium and should be avoided on a low-sodium diet. Sodium can contribute to high blood pressure and other health issues. Apples, chicken, and broccoli are all low in sodium and can be included in a low-sodium diet. Cheese is the only option that is high in sodium, making it the correct choice to avoid.

Correct Answer: C

Rationale: The correct answer is C: Axon. The axon is the part of the neuron that transmits impulses away from the cell body towards other neurons, muscles, or glands. Its structure allows for the rapid transmission of electrical signals. Rationale: 1. Dendrites receive signals and transmit them towards the cell body, so A is incorrect. 2. Neurolemma is the outermost layer of a Schwann cell, not a part of the neuron responsible for transmitting impulses, so B is incorrect. 3. The synapse is the junction between two neurons where communication occurs, not a part of the neuron transmitting impulses, so D is incorrect.

Correct Answer: C

Rationale: The correct answer is C: The patient is apprehensive about discharge. The rationale is that the patient's fear of going home and being alone indicates anxiety about leaving the hospital setting. This subjective data suggests that the patient may not feel ready for discharge despite stable vital signs and nearly healed incision. Choices A and B are incorrect because they assume the patient's readiness for self-care without considering emotional factors. Choice D is incorrect as there is no evidence provided that the surgery was unsuccessful.

Correct Answer: C
