PN ATI Comprehensive Predictor

Correct Answer: A

Rationale: The correct answer is A: Maintain sterility during dressing changes. It is crucial to maintain sterility during dressing changes for patients with central venous catheters to prevent infections. Changing the dressing weekly (Choice B) is not frequent enough to prevent infections effectively. Monitoring blood pressure and fluid balance (Choice C) is important for overall patient care but not specific to central venous catheter management. While monitoring the catheter site for infection (Choice D) is important, the key consideration is to prevent infections through proper sterile techniques during dressing changes.

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: C

Rationale: The correct instruction is to apply the prosthesis immediately upon waking each day. This helps the client adjust to and maintain mobility. Choice A is incorrect because wearing the prosthesis for only 2 hours at a time may not be sufficient for proper adjustment. Choice B is incorrect as removing the prosthesis every other day is not a standard practice and may hinder the client's mobility. Choice D is incorrect because elevating the stump for 24 hours after applying the prosthesis is unnecessary and not a recommended practice.

Correct Answer: A

Rationale: The correct signs and symptoms of Cushing's syndrome are weight gain and a moon face. Corticosteroids are used to manage Cushing's syndrome by reducing the overproduction of cortisol. Choice B is incorrect because hirsutism and thin extremities are not typical signs of Cushing's syndrome. Choice C is incorrect as purple striae and muscle weakness are more characteristic of the syndrome. Choice D is also incorrect as hypertension and bruising are not primary signs of Cushing's syndrome.

Correct Answer: B

Rationale: The correct answer is to check for air leaks and ensure the proper functioning of the chest tube. This action is crucial post-op to prevent complications such as pneumothorax or hemothorax. Clamping the chest tube every 2 hours (Choice A) is incorrect as it can lead to a buildup of pressure within the chest, risking complications. Encouraging deep breathing and coughing every 2 hours (Choice C) is important for respiratory hygiene but not the priority over ensuring the chest tube's proper function. Encouraging frequent coughing to clear secretions (Choice D) is not the priority when assessing a chest tube post-op; ensuring the chest tube's integrity and function take precedence.
