Nurse Jane is providing care for a client with superior vena cava syndrome. Which of the following interventions would be the priority?

Correct Answer: A

Rationale: The correct answer is to elevate the head of the bed. Elevating the head of the bed can help reduce the pressure on the superior vena cava, improve venous return, and facilitate breathing in clients with superior vena cava syndrome. Administering steroids (Choice B) may be necessary in some cases, but it is not the priority in the immediate care of a client with superior vena cava syndrome. Providing supplemental oxygen (Choice C) may help improve oxygenation but does not directly address the underlying issue of venous congestion. Administering diuretics (Choice D) may be contraindicated as it can further decrease preload and worsen the condition in superior vena cava syndrome.

Correct Answer: A

Rationale: The correct answer is A because metastasis refers to the spread of cancer cells to distant parts of the body, not the replication of cells. Choice B is correct as metastasis can indeed occur in various body parts. Choice C is incorrect as it inaccurately combines the concepts of replication and travel of cancer cells. Choice D is also correct as it accurately defines metastasis as the spread of cancer cells.

Correct Answer: D

Rationale: The correct answer is D because the statement 'Chemotherapy is effective in killing all cancer cells' is incorrect. Chemotherapy does not kill all cancer cells and is not the same as radiation therapy. Chemotherapy targets rapidly dividing cells, including cancer cells, but it may not kill every single cancer cell. It is important for the student nurse to understand and communicate this distinction to the patient. Choices A, B, and C provide accurate information about teletherapy, brachytherapy, and chemotherapy, respectively, and do not require additional teaching.

Correct Answer: C

Rationale: The correct answer is that normal cells undergo apoptosis, which is a programmed cell death process essential for maintaining tissue homeostasis. Choice A is incorrect as normal cells do have specific functions. Choice B is incorrect as the size of the nucleus may vary but is not a defining characteristic of normal cells. Choice D is incorrect as the color of the nucleus is not a standard characteristic of normal cells.

Correct Answer: D

Rationale: A diet high in fiber is not a risk factor for gastric cancer; in fact, it is generally considered protective against cancers. High sodium intake (Choice A) has been associated with an increased risk of gastric cancer. Diets with high amounts of chili garlic (Choice B) may irritate the stomach lining, potentially contributing to the development of gastric cancer. Smoking (Choice C) is a well-established risk factor for various types of cancers, including gastric cancer.
