Correct Answer: B

Rationale: The correct answer is B because the skin at the radiation site is sensitive to sunlight, and exposure can cause further damage. It is crucial to protect the area from direct sunlight to prevent skin irritation or burns. Choice A is incorrect as salt water typically does not pose a significant risk to the radiation site. Choice C is a positive and encouraging response but does not provide necessary advice for post-radiation care. Choice D, while important in some cases, is not directly related to the client's beach vacation after completing radiation treatments.

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: A

Rationale: The correct answer is A, 'Alopecia.' Alopecia is not a sign of testicular cancer; it can occur due to chemotherapy. Back pain (choice B) is not typically associated with testicular cancer. Painless testicular swelling (choice C) and a heavy sensation in the scrotum (choice D) can be actual signs of testicular cancer, so they do not require further information.

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.
