Correct Answer: B

Rationale: The correct answer is B. The best time to perform a testicular self-examination is after a warm shower when the scrotal skin is relaxed. This makes it easier to detect any abnormalities. Choice A is incorrect because the examination should ideally be done while standing. Choice C is incorrect as the client should use both hands to roll each testicle between the thumb and fingers to feel for any lumps or changes in size. Choice D is incorrect because testicular self-examinations are recommended to be done monthly, not every 6 months, to monitor changes in the testicles.

Correct Answer: A

Rationale: The correct answer is A, Hypercalcemia. In multiple myeloma, bone destruction can lead to the release of calcium from the bones into the bloodstream, causing hypercalcemia. This imbalance is commonly seen in patients with multiple myeloma. Choice B, Hyperproteinemia, is not typically associated with bone destruction in multiple myeloma. Choice C, Elevated serum viscosity, and Choice D, Elevated RBC count, are not directly related to the bone destruction seen in multiple myeloma.

Correct Answer: B

Rationale: Arm edema on the operative side (lymphedema) is a known complication after a mastectomy. This can indicate impaired lymphatic drainage, leading to fluid accumulation in the arm. Pain at the incision site is expected postoperatively and may not necessarily indicate a complication. Sanguineous drainage in the Jackson-Pratt drain is a common finding in the immediate postoperative period. Complaints of decreased sensation near the operative site could be related to nerve damage or surgical manipulation, but it is not a typical complication after a mastectomy.

Correct Answer: D

Rationale: The correct answer is D: Invading healthy host tissues. Invasion is the process where malignant cells grow into surrounding healthy tissues, allowing the cancer to spread to other parts of the body. Choices A, B, and C are incorrect. Adhering to primary tumor cells does not involve the transfer of cells to other locations, inducing mutation of cells of another organ is not a mechanism of cell transfer, and phagocytizing healthy cells refers to the process of engulfing and digesting cells, which is not a method of cancer cell transfer.

Correct Answer: C

Rationale: For patients experiencing difficulties with oral intake, the provision of small, easily chewed meals may be beneficial. Option A (TPN) and B (PEG tube placement) are more invasive interventions and should be considered if non-oral routes are necessary. Option D is not appropriate as the primary responsibility for a patient's nutrition should lie with healthcare professionals to ensure proper management and monitoring.
