A healthcare professional is interested in making interdisciplinary work a high priority. Which actions by the professional best demonstrate this skill? (Select ONE that does not apply)
- A. Consulting with other disciplines on client care
- B. Coordinating discharge planning for home safety
- C. Participating in comprehensive client rounding
- D. Sharing the care plans with other disciplines
Correct Answer: B
Rationale: The correct answer is B because coordinating discharge planning for home safety is not directly related to interdisciplinary work. The other choices (A, C, D) involve active collaboration and communication with different disciplines to ensure comprehensive client care. Consulting with other disciplines, participating in client rounding, and sharing care plans all demonstrate a high priority on interdisciplinary work by fostering teamwork and integration of various perspectives to enhance patient outcomes. In contrast, coordinating discharge planning for home safety is more focused on individual patient needs and safety rather than interdisciplinary collaboration.

A healthcare professional is assessing a client with rheumatoid arthritis. Which assessment finding is most characteristic of this disease?
- A. Asymmetrical joint involvement
- B. Heberden's nodes
- C. Morning stiffness lasting more than 30 minutes
- D. Pain that worsens with activity
Correct Answer: C
Rationale: The correct answer is C: Morning stiffness lasting more than 30 minutes. This is characteristic of rheumatoid arthritis due to the inflammatory nature of the disease. The prolonged morning stiffness is a hallmark feature, reflecting the systemic inflammation present in rheumatoid arthritis. This symptom is not typically seen in osteoarthritis, which rules out options A and B. Pain that worsens with activity is more indicative of osteoarthritis as opposed to rheumatoid arthritis, making option D incorrect.
