Correct Answer: B

Rationale: The correct answer is B: Resolve the client’s anxiety. Addressing the client's anxiety is the priority because it can impact their overall surgical experience, recovery, and outcomes. Resolving anxiety can improve the client's emotional well-being, enhance cooperation during surgery, and reduce postoperative complications related to stress. Providing emotional support and reassurance should be the initial focus to help the client feel more comfortable and confident about the upcoming surgery. The other choices are not the priority in this situation: A) Evaluating the need for antibiotics can be addressed later in the preoperative process, C) Providing preoperative education is important but not the immediate priority over addressing anxiety, and D) Preparing the client for surgery includes various components, but emotional well-being should be addressed first.

Correct Answer: C

Rationale: The correct answer is C: Stop the transfusion. Lumbar pain during blood administration could indicate a transfusion reaction, such as a hemolytic reaction or fluid overload. Stopping the transfusion is crucial to prevent further harm to the client. Obtaining vital signs (A) is important but not the priority when a transfusion reaction is suspected. Assessing the pain further (B) may delay necessary intervention. Increasing the flow of normal saline (D) is not indicated and may worsen fluid overload. In this situation, stopping the transfusion is the most appropriate action to ensure client safety.

Correct Answer: A

Rationale: The correct answer is A: Detects the presence of malignant cells. Biopsy involves taking a sample of tissue to examine under a microscope for the presence of abnormal or cancerous cells. This procedure is crucial for diagnosing cancer accurately. Choice B (Measures hemoglobin content) is incorrect because hemoglobin content is typically measured through blood tests, not biopsies. Choice C (Measures the RBC size) is incorrect as RBC size is usually assessed through a complete blood count (CBC) test, not a biopsy. Choice D (Detects arterial occlusion) is incorrect because arterial occlusion is typically diagnosed through imaging studies like Doppler ultrasound or angiography, not through a biopsy procedure.

Correct Answer: A

Rationale: The correct answer is A: circulating nurse. The circulating nurse is responsible for maintaining cleanliness, ensuring proper temperature, humidity, and lighting in the operating room. They coordinate activities, manage supplies, and ensure a safe environment for the surgical team. The scrub nurse assists the surgeon with instruments and supplies, not environmental conditions. The surgeon's main focus is on performing the surgery, not environmental management. The anesthesiologist is responsible for administering anesthesia and monitoring the patient's vital signs, not the operating room environment.

Correct Answer: D

Rationale: The correct answer is D because developing a formal nursing diagnosis helps nurses focus on their scope of practice, which includes identifying and addressing the patient's nursing care needs. By formulating a clear nursing diagnosis, nurses can prioritize interventions that are within their domain of expertise. This ensures efficient and effective patient care delivery. A: Incorrect. Developing a nursing diagnosis is not about creating a language exclusive to nurses; it is about identifying patient care needs. B: Incorrect. While nursing diagnoses do delineate the nurse's role, the primary purpose is not to distinguish it from the physician's role. C: Incorrect. Nursing diagnoses are based on evidence and critical thinking, not solely on intuition or others' judgments.
