This is important because it promotes patient empowerment, encourages active participation in healthcare decision-making, and enhances patient-provider communication.
Choice A is incorrect because the primary purpose of an electronic health record is not for providers to track client information for research studies.
Choice C is incorrect as it inaccurately states that electronic health records coordinate all healthcare received into one platform.

Correct Answer: D

Rationale: The correct way to use a cane while walking is to hold it on the opposite side of the affected leg (
Choice
D). This positioning helps to provide the necessary support and stability for the affected side. By holding the cane on the opposite side, it helps to offload weight from the affected leg, reducing pressure and pain. Additionally, this positioning allows for a more balanced and natural walking pattern. Holding the cane on the same side as the affected leg (
Choice
A) may not provide adequate support and can lead to imbalance. Holding the cane behind the body (
Choice
B) can cause awkward positioning and may not effectively support the affected leg. Holding the cane in the middle of the body (
Choice
C) does not provide targeted support for the affected leg.

Correct Answer: D

Rationale: The purpose of evidence-based practice (EBP) in nursing is to improve patient outcomes and quality of care. This is achieved by integrating the best available evidence with clinical expertise and patient values. By using evidence-based practice, nurses can make informed decisions that are based on research and proven effectiveness, leading to better patient care.


Choice A is incorrect because EBP focuses on individualized care based on evidence, not standardized protocols.
Choice B is incorrect as EBP involves critically evaluating practices, not just relying on established ones.
Choice C is incorrect because EBP emphasizes using research evidence over tradition and personal beliefs.

Rationale: Taking breaks during a shift is an example of safe ergonomic practice as it allows nurses to rest and prevent musculoskeletal injuries. This practice promotes proper body mechanics and reduces the risk of fatigue.

Explanation of Incorrect

Choices:
A: Lifting a client alone can lead to back injuries and is not safe ergonomic practice.
C: Reaching across a client's bed to lift an object can strain the nurse's muscles and cause injury.
D: Working frequent overtime can lead to fatigue and increase the risk of musculoskeletal injuries.

Correct Answer: D

Rationale: The correct answer is D: Client's self-report of pain. This method is the most reliable because pain is subjective and varies greatly among individuals. The client's self-report provides direct insight into their experience of pain, allowing for personalized and accurate pain assessment. Vital sign measurement (
A) may indicate distress but doesn't capture the full extent of pain. The nature of invasiveness of the surgical procedure (
B) may give an indication of potential pain but doesn't reflect the individual's actual experience. Visual observation (
C) for nonverbal signs of pain can be helpful but may not always accurately reflect the client's pain level.
