Correct Answer: D

Rationale: The correct answer is D because clients taking warfarin should avoid aspirin to reduce the risk of bleeding, as both medications can thin the blood. Choice A is incorrect because it is essential to eat a consistent amount of leafy green vegetables to maintain a steady intake of Vitamin K, which can impact warfarin's effectiveness. Choice B is incorrect although important because INR checks are necessary but do not specifically show an understanding of the teaching. Choice C is incorrect because while taking warfarin at the same time each day is beneficial for consistency, it does not directly address the interaction with aspirin.

Correct Answer: D

Rationale: The correct answer is D. Dyspnea in a client with COPD receiving oxygen should be reported as it may indicate worsening respiratory status. Oxygen saturation of 95% is within the expected range for a client receiving oxygen therapy and does not require immediate reporting. A productive cough with clear sputum is a common symptom in clients with COPD and does not necessarily warrant urgent reporting. A respiratory rate of 22/min is also within normal limits and does not raise immediate concerns in this scenario.

Correct Answer: D

Rationale: The correct answer is D: Positive rheumatoid factor. A positive rheumatoid factor is a common laboratory finding in clients with rheumatoid arthritis, indicating an autoimmune response. Option A, increased WBC count, is not typically associated with rheumatoid arthritis. Option B, decreased hemoglobin, and option C, decreased platelet count, are not specific laboratory findings for rheumatoid arthritis.

Correct Answer: A

Rationale: A hemoglobin level of 11.2 g/dL is below the normal range for a client who is 36 weeks gestation and should be reported to the provider.

Correct Answer: C

Rationale: The correct answer is C: Diaphoresis. Diaphoresis, which is excessive sweating, is a common response to acute pain due to increased sympathetic nervous system activity. Options A and B, Bradycardia and Hypotension, are unlikely findings in a client experiencing acute pain as pain usually triggers an increase in heart rate (tachycardia) and blood pressure. Option D, Hyperactive bowel sounds, is not typically associated with acute pain.
