The nurse is assessing a client with leukemia who is receiving chemotherapy. Which of the following findings would be of most concern?

Correct Answer: D

Rationale: The correct answer is D, 'Mouth sores.' Mouth sores (stomatitis) are a common and potentially serious side effect of chemotherapy. They can lead to difficulty eating, increased risk of infection, and overall decreased quality of life for the client. While alopecia, fatigue, and nausea/vomiting are also common side effects of chemotherapy, they are generally manageable and do not pose the same level of immediate concern as the development of mouth sores in a client undergoing chemotherapy.

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.

Correct Answer: D

Rationale: The correct answer is to elevate the affected arm. Elevating the affected arm helps prevent lymphedema after a mastectomy. Choices A, B, and C are incorrect. 'Dangling arms at the bedside' does not provide any benefit after a mastectomy. 'Lying down on the affected chest' can cause discomfort and possible complications. 'Drinking plenty of fluids immediately after surgery' is not related to preventing lymphedema post-mastectomy.
