Correct Answer: B

Rationale: The correct answer is B: Fine needle aspiration. This is because fine needle aspiration involves extracting cells from the lump in the breast for examination under a microscope to determine if they are cancerous. This procedure provides a definitive diagnosis of breast cancer. Breast self-examination (A) is a screening tool for detecting lumps but does not confirm a diagnosis. Mammography (C) is used for screening and detecting abnormalities but requires further testing for confirmation. Chest x-ray (D) is not useful for diagnosing breast cancer.

Correct Answer: B

Rationale: The correct answer is B: prothrombin time. In liver cirrhosis, the liver's ability to produce clotting factors is impaired, leading to prolonged prothrombin time. This indicates an increased risk of bleeding. Choice A is incorrect as carbon dioxide levels are not typically affected by liver cirrhosis. Choice C, gastric pH, is unrelated to liver function. Choice D, white blood cell count, is not directly affected by liver cirrhosis. Therefore, the alteration in prothrombin time is the most relevant laboratory value to monitor in this case.

Correct Answer: A

Rationale: Step 1: Reassessing the wound and client's condition allows the nurse to identify any factors contributing to the lack of improvement. Step 2: It helps determine if the current care plan needs modifications or if there are underlying issues affecting healing. Step 3: This step ensures a comprehensive evaluation before making any changes to the care plan, promoting evidence-based practice. Step 4: Choosing this option aligns with the nursing process of assessment, which is crucial for making informed decisions in client care. Summary: Option A is correct as it emphasizes the importance of reassessment to gather more information and make informed decisions. Discontinuing the care plan (Option B) without assessment can be harmful. Increasing dressing changes (Option C) may not address the underlying issue. Referring immediately (Option D) may be premature without reassessment.

Correct Answer: B

Rationale: The correct answer is B: Health behavior. Evaluating the patient's demonstration of self-injection assesses their ability to perform a specific health-related action. This choice focuses on the patient's actions and behaviors related to their health, aligning with the scenario provided. Choice A: Health status is incorrect because it refers to the patient's current physical condition, not their ability to perform a specific health action. Choice C: Psychological self-control is incorrect as it pertains to the patient's ability to regulate their emotions and impulses, not their ability to self-administer injections. Choice D: Health service utilization is incorrect as it relates to the frequency and pattern of healthcare services used by the patient, not their ability to perform a specific health behavior.
