Correct Answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

Correct Answer: D

Rationale: The correct first action for the nurse to take when assessing a client with a new diagnosis of Listeria food poisoning is to inquire if the client has consumed any unpasteurized products. This is crucial because Listeria contamination is often associated with unpasteurized dairy products and undercooked meats. Educating the client on safe food practices (Choice A) is important but not the priority at this initial assessment stage. Starting a traceback to identify the source of the outbreak (Choice B) and reporting the case to the county board of health (Choice C) are necessary actions but should come after gathering information directly from the client regarding potential exposure to high-risk foods.

Correct Answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.

Correct Answer: C

Rationale: In this situation, the first step should be to report the matter to your supervisor. It is essential to notify the appropriate authority immediately to address the discrepancy in the narcotics cabinet. Choice A is not the first step as reporting to the nursing director should follow after informing the supervisor. Keeping the findings to yourself (Choice B) is not appropriate as it may jeopardize patient safety and is against ethical standards. While finding out which patient received narcotics (Choice D) is important, it is not the immediate action to take in this scenario.

Correct Answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.
