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: 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.

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 multiple myeloma (choice C). Back pain is a common presenting symptom in multiple myeloma, especially in older patients. This malignancy can lead to bone pain due to bone destruction and fractures. Hodgkin disease (choice A) and Non-Hodgkin lymphoma (choice B) typically present with symptoms like painless lymph node enlargement, fever, and weight loss. Acute thrombocythemia (choice D) is characterized by an increase in platelet count but is not typically associated with the symptoms described by the patient.

Correct Answer: D

Rationale: Inspiratory stridor is the correct answer as it suggests airway obstruction, a critical issue requiring immediate intervention. Frequent swallowing (choice A) is a common postoperative finding and does not indicate an immediate need for intervention. The presence of mucous membranes (choice B) is a normal finding and does not require immediate intervention. Bubbling in the water-seal chamber (choice C) of a chest tube drainage system is an expected finding and indicates proper functioning of the system, not an immediate need for intervention.
