Correct Answer: B

Rationale: Radiation-induced fatigue can last for months; it's important to normalize this for the client.

Correct Answer: D

Rationale: The correct answer is D: Peripheral neuropathy. Bortezomib, used in the treatment of multiple myeloma, is known to cause peripheral neuropathy as a significant adverse effect. Stomatitis (Choice A), which is inflammation of the mouth and lips, is not a common adverse effect of bortezomib. Nephropathy (Choice B), referring to kidney disease, is not a typical adverse effect of bortezomib. Cognitive changes (Choice C) are not a commonly reported adverse effect of bortezomib treatment.

Correct Answer: D

Rationale: The correct answer is D: Teaching measures to prevent scalp injury. Alopecia makes the scalp more vulnerable to injury, so educating clients on protective measures is crucial. Choices A and B focus on emotional support and reassurance, which are important but secondary to physical safety. Referring clients to a wig shop (choice C) addresses appearance but does not directly address the physical risk associated with scalp vulnerability.

Correct Answer: C

Rationale: The correct answer is to schedule the client for a chest x-ray. A positive Mantoux test indicates exposure to TB, but it does not confirm active disease. A chest x-ray is necessary to assess the presence of active TB disease. Isolating the client in a private room (Choice A) is not necessary based solely on a positive Mantoux test result. Administering isoniazid (INH) (Choice B) or beginning a 9-month course of medication therapy (Choice D) is premature without confirming active TB through a chest x-ray.

Correct Answer: B

Rationale: The correct answer is B. Malignant cells have different proteins in their membranes, such as tumor-specific antigens, which distinguish them from benign cells. Choice A is incorrect as cancer cells typically have a rapid and uncontrolled rate of mitosis. Choice C is incorrect as the size of cells alone does not distinguish between malignant and benign cells. Choice D is incorrect as the molecular structure is not the primary characteristic that distinguishes between malignant and benign cells.
