Which statement by a nurse indicates a good understanding about the differences between data validation and data interpretation?

Correct Answer: C

Rationale: The correct answer is C because data validation involves comparing data with other sources to ensure accuracy. This process helps in identifying any discrepancies or errors in the data. By cross-referencing with other sources, the nurse can verify the correctness of the data. Rationale: 1. Data validation checks the accuracy of the data by comparing it with external sources. 2. Data interpretation involves analyzing and making sense of the data, not comparing it with other sources. 3. Option A is incorrect because data validation typically comes after data collection and precedes data interpretation. 4. Option B is incorrect as validation does not specifically involve looking for patterns in professional standards. 5. Option D is incorrect because data interpretation focuses on understanding trends and insights from the data, not patterns in professional standards.

Correct Answer: B

Rationale: The correct answer is B because using a PICOT question involves formulating a research question to guide evidence-based practice. B indicates the nurse is implementing interventions based on scientific research, aligning with the PICOT framework (Patient, Intervention, Comparison, Outcome, Timeframe). This approach ensures that care decisions are supported by the best available evidence, leading to improved patient outcomes. Choice A is incorrect because practicing nursing based on court evidence does not align with the PICOT framework. Choice C is incorrect as using standardized care plans for all patients may not consider individual patient needs and preferences as required in a PICOT question. Choice D is incorrect as planning care based on tradition does not involve integrating current research evidence as in the PICOT approach.

Correct Answer: B

Rationale: The correct answer is B, notifying the health care provider. This is the most appropriate initial intervention because chest pain can be a symptom of a serious medical condition like a heart attack. The health care provider needs to be informed immediately to assess the situation and provide appropriate treatment. Reassessing the patient (A) may delay crucial medical intervention. Administering pain medication (C) without knowing the cause of chest pain can be dangerous. Calling radiology for a chest x-ray (D) is not the initial step in managing new onset chest pain.

Correct Answer: C

Rationale: The correct answer is C because measuring the wound and observing for redness, swelling, or drainage are essential steps in evaluating wound healing progress. Measuring the wound provides objective data on its size changes, while observing for signs of infection like redness, swelling, or drainage helps identify complications. - Choice A is incorrect because the nursing assistive personnel may not have the necessary knowledge to assess wound healing accurately. - Choice B is incorrect because documenting progress as "better" without objective data is subjective and does not provide a clear picture of the wound status. - Choice D is incorrect because leaving the dressing off can expose the wound to contaminants and compromise healing, making it a potentially harmful action.

Correct Answer: C

Rationale: Subjective data are information reported by the patient that cannot be measured or observed directly. In this case, nausea and abdominal pain are symptoms that can only be described by the patient, making them subjective data. Vomiting, pulse rate, respirations, blood pressure, pale skin, and thick toenails are all objective data, as they can be measured or observed directly by the healthcare provider. Therefore, choice C is the correct answer as it represents subjective data.
