Correct Answer: C

Rationale: Choice C is the most therapeutic response as it acknowledges the patient's anxiety and encourages reflection on his behavior. This approach can help the patient explore his feelings and thoughts about smoking in relation to his surgery, promoting self-awareness and potentially opening the door for a constructive discussion. Choices A and B are more directive and may not address the underlying anxiety and need for reflection. Choice D is also somewhat permissive about smoking before surgery, which may not be in the patient's best interest.

Correct Answer: A

Rationale: The correct action by the nurse is to assess the client's blood pressure and pulse. Difficulty breathing can be a sign of various conditions, including cardiac issues. Assessing blood pressure and pulse helps in determining the client's hemodynamic status and identifying any cardiovascular compromise. Option B is less crucial as attaching the client to a pulse oximeter may provide oxygen saturation levels but does not directly assess cardiac output. Option C is not the priority in this situation as the client's difficulty breathing is a more urgent concern. Option D is incorrect as urgent radiation therapy is not indicated based on the client's presentation.

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: A

Rationale: The correct answer is A because enemas can cause injury to a thrombocytopenic client due to the risk of bleeding. Choices B, C, and D are correct precautions for a client with thrombocytopenia. Using an electric shaver reduces the risk of cuts that could lead to bleeding. Eating soft, cool, or warm food helps prevent injuries to the oral mucosa. Avoiding activities like sports that carry a risk of injury is also advisable.

Correct Answer: A

Rationale: The correct answer is A. Palliative care focuses on managing symptoms and improving the quality of life for clients with serious illnesses like cancer. Choice B is incorrect as palliative care can be provided alongside curative treatments. Choice C is incorrect because palliative care does not aim to prolong life at all costs; it focuses on improving the quality of life. Choice D is partially correct but does not fully capture the essence of palliative care, which includes symptom management and holistic support for the client and their family.
