ATI Comprehensive Predictor PN

Correct Answer: C

Rationale: An elevated creatinine level indicates impaired kidney function, which may affect the client's ability to undergo surgery. The other laboratory values (white blood cell count, potassium level, and hemoglobin level) are within normal ranges and do not directly impact the client's readiness for surgery.

Correct Answer: B

Rationale: When caring for clients with dementia, addressing restlessness and agitation is a priority as it can lead to distress, safety risks, and potential harm to the client or others. Restlessness and agitation are common behavioral symptoms of dementia and can indicate unmet needs, discomfort, or confusion. Managing these symptoms promptly can help improve the client's quality of life and prevent complications such as falls, injuries, or escalation of challenging behaviors. While other issues like mild confusion, incontinence, and wandering are also important to address, managing restlessness and agitation takes precedence due to its immediate impact on the client's well-being and safety.

Correct Answer: C

Rationale: Placing a pillow between the client's legs is beneficial after hip replacement surgery to maintain proper alignment and prevent dislocation of the prosthesis. This position helps keep the hip in a neutral position, reducing the risk of dislocation. Encouraging the client to bend at the waist (Choice A) can increase the risk of hip dislocation. Maintaining the client in a high-Fowler's position (Choice B) and avoiding placing a pillow under the client's knees (Choice D) do not directly address the need to maintain proper alignment of the hip joint to prevent dislocation.

Correct Answer: B

Rationale: The best intervention for managing dehydration is to monitor fluid and electrolyte levels. This approach allows healthcare providers to assess the severity of dehydration, determine appropriate fluid replacement therapy, and prevent complications. Administering antiemetics (Choice A) may help with nausea but does not address the underlying issue of dehydration. Encouraging the client to drink more fluids (Choice C) may be appropriate for mild dehydration but can be inadequate for moderate to severe cases. Administering intravenous fluids (Choice D) is crucial for severe dehydration or cases where oral rehydration is ineffective, but monitoring fluid and electrolyte levels should precede this intervention.

Correct Answer: C

Rationale: The correct answer is C: Apply a sequential compression device. Applying a sequential compression device promotes venous return by assisting with blood circulation in the lower extremities, reducing the risk of blood clots. Encouraging deep breathing exercises can help with lung expansion but does not directly promote venous return. Maintaining the client in a supine position may not be ideal for promoting venous return if the client is unable to move. Massaging the client's legs may be contraindicated postoperatively due to the risk of dislodging a clot or causing trauma to the surgical site.
