PN ATI Comprehensive Predictor

Correct Answer: B

Rationale: The correct answer is B because pallor in an extremity after a fracture could indicate compromised circulation, making it a priority for assessment. Choice A is not the priority as hypoactive bowel sounds in a client 1 hr postoperative, while concerning, do not indicate a life-threatening condition. Choice C, a client who had a cardiac catheterization 3 hr ago and has 3+ pedal pulses, indicates good perfusion and does not require immediate attention. Choice D, a client with an elevated AST level following the administration of azithromycin, may require further assessment but is not as urgent as the client with potential compromised circulation in choice B.

Correct Answer: B

Rationale: Using a bed exit alarm is the best intervention to prevent injury in a client with dementia at risk of falling. This device alerts staff when the client attempts to leave the bed, allowing for timely assistance and reducing the risk of falls. Placing the client in a room close to the nurses' station may help with supervision but does not provide immediate alerts like a bed exit alarm. Encouraging family members to stay with the client at all times may not be feasible, and raising all four side rails can lead to restraint issues and is not recommended unless necessary for the client's safety.

Correct Answer: B

Rationale: When a client with a tracheostomy is experiencing respiratory distress, the priority action is to suction the tracheostomy to clear the airway and improve breathing. This helps remove secretions or blockages that may be causing the distress. Notifying the healthcare provider (Choice A) can be done after ensuring immediate airway clearance. Administering a bronchodilator (Choice C) would not address the primary issue of airway clearance in a tracheostomy patient. Increasing the oxygen flow rate (Choice D) may be necessary but should come after ensuring the airway is clear.

Correct Answer: C

Rationale: Regaining orientation to time and place is a realistic short-term goal for clients with delirium. It helps the individual become aware of their surroundings and current situation, aiding in reducing confusion and disorientation. Choice A is incorrect because the goal is focused on the client's understanding, not on explaining the experience of delirium. Choice B, resuming a normal sleep-wake cycle, may take longer than 2 to 3 days to achieve and is not directly related to regaining orientation. Choice D, establishing normal bowel and bladder function, is important but may not be a short-term goal specifically related to delirium.

Correct Answer: A

Rationale: The correct answer is A: Hypoventilation and lung disease. Respiratory acidosis occurs when there is an accumulation of CO2 in the body due to inadequate ventilation. Hypoventilation, which reduces the elimination of CO2, and lung diseases that impair gas exchange are the primary causes. Choice B is incorrect because hyperventilation, not hypoventilation, leads to respiratory alkalosis, not acidosis. Choice C is incorrect because increased oxygen saturation and tachypnea do not directly cause respiratory acidosis. Choice D is incorrect as dehydration and hypoxia do not typically lead to respiratory acidosis.
