ATI Comprehensive Predictor PN

Correct Answer: A

Rationale: Assessing mobility should be the nurse's priority as it ensures the client's safety and helps in developing an appropriate care plan. By evaluating the client's ability to move after the knee arthroplasty, the nurse can identify any immediate issues or complications that need to be addressed promptly. Monitoring vital signs, providing pain relief, and reinforcing discharge teaching are important aspects of care but assessing mobility takes precedence in ensuring the client's immediate well-being and identifying any potential risks.

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: A

Rationale: Emptying the colostomy bag regularly is essential to prevent leakage and infection. By regularly emptying the bag, the risk of irritation to the skin surrounding the stoma is reduced. Providing a high-fiber diet is important for overall bowel health but is not directly related to colostomy care. While monitoring for signs of infection is crucial, the primary focus should be on proper bag emptying. Changing the colostomy bag every 3 days may not be necessary for all patients and could vary based on individual needs and the type of colostomy.

Correct Answer: A

Rationale: The correct answer is A: Increased respiratory rate and use of accessory muscles are key signs of respiratory distress. When a person is experiencing respiratory distress, their respiratory rate typically increases as the body tries to compensate for the inadequate oxygenation. Additionally, the use of accessory muscles indicates that the person is working harder to breathe. Choices B, C, and D are incorrect because they do not accurately represent the key signs of respiratory distress. A decreased respiratory rate, cyanosis, altered mental status, and bradycardia are not typical signs of respiratory distress.

Correct Answer: D

Rationale: The correct answer is D. New onset of tachypnea indicates a potential respiratory complication that requires immediate attention. Assessing the client with a hip fracture and tachypnea first is crucial to address the respiratory issue and prevent further deterioration. Choices A, B, and C do not present immediate life-threatening complications that require urgent assessment compared to a new onset of tachypnea.
