Correct Answer: C

Rationale: The correct answer is C: Diagnostic reasoning. This involves analyzing assessment data, utilizing critical thinking skills to identify patient problems, and formulating nursing diagnoses. Diagnostic reasoning is the process of synthesizing information to make clinical judgments and determine appropriate interventions. A: Assigning clinical cues - Incorrect. This refers to identifying observable signs or symptoms, not the process of developing a nursing diagnosis. B: Defining characteristics - Incorrect. This term is often used to describe the symptoms or manifestations associated with a nursing diagnosis, not the process of deriving the diagnosis. D: Diagnostic labeling - Incorrect. This is the final step in the nursing diagnosis process where the nurse assigns a label to the identified patient problem, not the process of critical thinking and data analysis.

Correct Answer: C

Rationale: The correct answer is C: Diagnostic reasoning. The nurse is using assessment data to analyze, interpret, and make a judgement about the patient's condition. This process involves critical thinking skills to develop a nursing diagnosis. Choice A (Assigning clinical cues) is incorrect because it refers to identifying specific signs and symptoms. Choice B (Defining characteristics) is incorrect as it pertains to the features of a diagnosed condition. Choice D (Diagnostic labeling) is incorrect because it focuses on naming a specific nursing diagnosis. Diagnostic reasoning encompasses the entire process of analyzing data, making connections, and formulating a nursing diagnosis based on critical thinking.

Correct Answer: C

Rationale: The correct answer is C: Performing a physical examination. This method allows the nurse to directly gather patient data through observation, palpation, percussion, and auscultation. It helps in assessing the patient's overall health status, identifying any abnormalities, and establishing a baseline for further care. Reviewing literature (A) helps in evidence-based practice but does not directly collect patient data. Checking orders for tests (B) and ordering medications (D) involve actions based on data collected rather than collecting the data itself.

Correct Answer: B

Rationale: Correct Answer: B Rationale: Measuring intake and output and recommending increased fluid intake for a client with pyelonephritis is crucial to help flush out infectious microorganisms from the urinary tract. By increasing fluid intake, the client will urinate more frequently, aiding in the removal of bacteria causing the infection. This helps in reducing the bacterial load in the urinary tract and promoting faster recovery. Monitoring intake and output also helps ensure the client is adequately hydrated. Summary of Other Choices: A: Monitoring intake and output is more about assessing hydration status and kidney function rather than the response to therapy. C: Intake and output measurement does not directly determine the location of discomfort in pyelonephritis. D: Monitoring intake and output is not primarily for detecting changes but for ensuring proper fluid balance and aiding in infection clearance.

Correct Answer: D

Rationale: Autoimmunity is when the immune system mistakenly attacks the body's own cells. Choice D is correct because it reflects this key feature - the inability to differentiate self from nonself. This leads to the immune system targeting healthy tissues. Choices A, B, and C are incorrect as they do not accurately describe autoimmunity. Choice A refers to endotoxins destroying B cells, which is not the definition of autoimmunity. Choice B mentions overproduction of reagin antibody, which is not related to autoimmunity. Choice C is incorrect as autoimmunity does not involve depression of the immune response but rather an inappropriate immune response.
