Nonverbal behaviors are just as important as verbal behaviors. Please mark the following behaviors as positive or negative. a. Tapping a pen rhythmically on the table.

Correct Answer: B

Rationale: The correct answer is B: Negative. Tapping a pen rhythmically on the table can be distracting to others and disrupt the communication process. It can convey impatience, nervousness, or lack of focus. Nonverbal behaviors should support and enhance verbal communication, not detract from it. Other choices are not applicable as the behavior described is clearly negative.

Correct Answer: D

Rationale: Kienböck's disease is osteonecrosis of the lunate bone. This occurs due to disrupted blood supply, leading to lunate collapse and wrist pain. Option D is correct as it directly relates to the pathology of Kienböck's disease. Options A, B, and C are incorrect as they do not describe the specific feature associated with Kienböck's disease. Osteonecrosis of the scaphoid (Option A) is more commonly seen in Preiser's disease, while Pencil-in-cup deformities (Option B) are typically associated with psoriatic arthritis. Heberden's and Bouchard's nodules (Option C) are seen in osteoarthritis of the fingers, not in Kienböck's disease.

Correct Answer: C

Rationale: The correct answer is C: MRI. MRI is the 'gold standard' for evaluating the rotator cuff due to its high sensitivity and specificity in detecting rotator cuff tears and other pathologies. It provides detailed imaging of soft tissues, allowing for better visualization of the rotator cuff structures. Plain x-rays are not ideal for evaluating soft tissues like the rotator cuff. Physical exam of the shoulder can provide valuable information, but it may not be as accurate as imaging tests. Ultrasound can be useful, but it is not as sensitive or specific as MRI for detecting rotator cuff tears. In summary, MRI is the preferred diagnostic test for evaluating the rotator cuff due to its superior imaging capabilities and accuracy in detecting pathologies.

Correct Answer: C

Rationale: The correct answer is C: Validate the data by asking a coworker to listen to the breath sounds. This is the best course of action as it involves seeking a second opinion to confirm the unclear sound heard, ensuring accuracy in assessment. Notifying the physician immediately (A) may be premature without validation. Documenting the sound (B) without confirmation can lead to inaccurate documentation. Assessing again in 20 minutes (D) may delay necessary intervention if the sound is significant. Asking a coworker to validate the data (C) allows for immediate clarification and ensures accurate assessment.

Correct Answer: A

Rationale: Step 1: Evidence-based practice (EBP) requires nurses to critically evaluate research studies. Step 2: To incorporate EBP, nurses need research skills to assess the quality of studies. Step 3: Lack of research skills hinders nurses from effectively utilizing EBP. Step 4: Choice A is correct as it directly addresses a barrier to incorporating EBP. Summary: Choices B, C, and D are incorrect as they do not specifically relate to the need for research skills in evaluating the quality of research studies, which is essential for implementing EBP.
