A client with vision loss is being cared for by a nurse. Which of the following actions should the nurse take?

Correct Answer: A

Rationale: The correct action for the nurse to take is to keep objects in the client's room in the same place. This helps individuals with vision loss navigate their environment more easily by creating a familiar and consistent layout. Choice B, ensuring high-wattage lighting, may not be suitable for all clients with vision loss and can cause discomfort or glare. Approaching the client from the side (Choice C) can startle them and is not recommended. Touching the client (Choice D) without warning may cause anxiety or distress, so it's important to announce presence verbally.

Correct Answer: A

Rationale: The correct answer is A. Children with varicella are contagious until the vesicles crust over, which is important for preventing transmission. Choice B is incorrect as varicella and herpes zoster are caused by different viruses, so the varicella vaccine is given to prevent varicella, not herpes zoster. Choice C is incorrect because varicella is primarily spread through respiratory secretions, so airborne precautions are recommended, not droplet precautions. Choice D is incorrect as children with varicella are contagious even before the first vesicle eruption, not just 4 days before.

Correct Answer: A

Rationale: The correct answer is A: Quality improvement. Completing an incident report after a client fall aligns with the quality improvement competency of QSEN, as it involves identifying a system issue (fall incident) that needs to be addressed to enhance the quality of care. Choice B, patient safety, focuses more on preventing harm to patients rather than the systematic improvement process. Choice C, evidence-based practice, pertains to integrating research evidence with clinical expertise and patient values in decision-making, which is not directly related to incident reporting. Choice D, informatics, involves using technology and data to support decision-making and improve patient care, which is not the primary focus when completing an incident report.

Correct Answer: C

Rationale: The correct position for a client immediately postoperative following a hip arthroplasty is the lateral position with an abduction pillow between the legs. This position helps prevent dislocation of the hip prosthesis and maintains proper alignment of the hip joint. Supine position with legs extended (Choice A) may put stress on the hip joint, Semi-Fowler's position with legs bent (Choice B) may not provide adequate support and alignment, and prone position with legs elevated (Choice D) is not recommended after hip arthroplasty as it can compromise the surgical site and increase the risk of complications.

Correct Answer: B

Rationale: Keeping the client's legs elevated is the appropriate action to prevent venous thromboembolism following a total knee arthroplasty. Elevating the legs helps promote circulation and reduce the risk of blood clots. Placing a pillow under the client's knees may provide comfort but does not address the specific postoperative complication. Flexing the client's knee every 2 hours may be contraindicated as excessive movement can disrupt the surgical site. Applying heat to the operative knee is not recommended immediately postoperatively as it can increase swelling and discomfort.
