RN ATI Capstone Proctored Comprehensive Assessment A

Correct Answer: A

Rationale: The correct answer is to check the ventilator tubing for disconnection first when a patient on mechanical ventilation experiences a sudden drop in oxygen saturation. This is crucial because equipment malfunction, such as tubing disconnection, can lead to decreased oxygen delivery, resulting in a drop in oxygen saturation. Checking the tubing ensures that the ventilation system is functioning properly and that the patient is receiving the necessary oxygen. Option B is incorrect because increasing oxygen flow without checking for equipment issues may not address the root cause of the drop in saturation. Option C is not the priority in this situation as the immediate focus should be on assessing and ensuring the functioning of the ventilation equipment. Option D delays addressing the potential equipment malfunction, which could worsen the patient's condition if not promptly resolved.

Correct Answer: A

Rationale: The correct answer is to encourage early ambulation and leg exercises. By promoting early ambulation and leg exercises, blood flow is enhanced, reducing the risk of venous thromboembolism (VTE) in postoperative patients. Choice B, applying compression stockings, helps prevent VTE but is not as effective as early ambulation and exercises. Choice C, administering anticoagulants, is important in VTE prevention but does not directly address improving circulation through physical activity. Choice D, elevating the patient's legs, may be beneficial for circulation in specific cases but is not as effective in preventing VTE as early ambulation and leg exercises.

Correct Answer: A

Rationale: The correct answer is to administer a bronchodilator as prescribed. This intervention is the priority for a patient with asthma experiencing shortness of breath as it helps relax the airways, making breathing easier. Encouraging the use of an incentive spirometer (Choice B) is beneficial for lung expansion but not the priority in this acute situation. Placing the patient in a high Fowler's position (Choice C) can also help with breathing but is not as immediate as administering a bronchodilator. While monitoring the patient's oxygen saturation closely (Choice D) is important, the immediate action to address the breathing difficulty is administering a bronchodilator.

Correct Answer: C

Rationale: The correct understanding of standard precautions includes wearing appropriate personal protective equipment to prevent exposure to body fluids. Wearing eyewear when emptying the urinary drainage bag is crucial as it protects the nurse's eyes from potential splashes of body fluids. Teaching the patient about good nutrition (Choice A) is important for overall health but is not directly related to standard precautions. Disposing of an uncapped needle correctly (Choice B) is part of safe needle handling but does not specifically relate to standard precautions. Donning gloves when wearing artificial nails (Choice D) is not a correct understanding of standard precautions, as artificial nails can harbor microorganisms and increase the risk of infection transmission.

Correct Answer: D

Rationale: The correct answer is to remove the restraint (Choice D). Cyanosis of the toes, indicated by a light blue color, suggests impaired circulation. The priority action is to ensure proper circulation by removing the restraint to prevent further compromise. Choices A and B are not the immediate actions needed for cyanosis related to impaired circulation. Choice C, placing a blanket over the feet, does not address the underlying issue of impaired circulation and could delay appropriate intervention.
