Contemporary nursing requires that the nurse possess knowledge, skills and attitudes for a variety of professional roles and responsibilities. Examples include:

Correct Answer: D

Rationale: Contemporary nursing demands autonomy and accountability nurses independently make decisions within their scope and take responsibility for outcomes, reflecting roles like educator, advocate, and clinician. This aligns with evolving healthcare, where nurses lead initiatives (e.g., patient education) and answer for care quality. Health promotion and illness prevention are key foci but specific tasks, not broad role examples. Providing bedside care is traditional, not fully capturing modern diversity (e.g., research, management). Following physician orders reflects dependence, not the autonomy defining today's practice. Autonomy and accountability encompass the knowledge (clinical expertise), skills (critical thinking), and attitudes (responsibility) needed for multifaceted roles, making this the best fit for contemporary nursing's scope.

Correct Answer: D

Rationale: A trapeze bar, attached overhead, assists patients in changing position (e.g., lifting to sit), enhancing mobility and reducing nurse strain e.g., for a post-op client. Sand bags immobilize (e.g., a fractured leg), not aiding movement. Bed cradle (likely 'crackle' typo) lifts sheets off limbs, preventing pressure, not repositioning. Removable headboards aid CPR access, unrelated to patient movement. The trapeze bar's function position change support matches its clinical use, per nursing equipment standards, making it the best match in this adapted format.

Correct Answer: B

Rationale: One teaspoon (5 ml) equals approximately 60 drops (gtts), based on standard drop size.

Correct Answer: C

Rationale: CBR stands for Complete Bed Rest, restricting patient mobility.

Correct Answer: D

Rationale: All rate, rhythm, and symmetry are essential to assess respiratory function.
