ATI RN Exit Exam Quizlet

Correct Answer: A

Rationale: The correct answer is to monitor aPTT levels. Activated Partial Thromboplastin Time (aPTT) is crucial for assessing the therapeutic effectiveness of heparin, as it reflects the intrinsic pathway of the coagulation cascade. Monitoring aPTT helps ensure that the patient is within the therapeutic range of heparin, minimizing the risk of bleeding complications. Platelet count (choice B) is important to assess for potential heparin-induced thrombocytopenia but is not the primary lab value to monitor during heparin therapy. INR levels (choice C) are monitored in patients on warfarin therapy, not heparin. Sodium levels (choice D) are not directly related to heparin therapy monitoring.

Correct Answer: C

Rationale: The correct answer is C: 'Wear compression stockings daily.' Wearing compression stockings is essential after knee surgery to prevent venous stasis and reduce the risk of blood clots. Choice A is incorrect as crossing legs when sitting can increase the risk of blood clots. Choice B is incorrect because performing range-of-motion exercises every 4 hours may not be suitable for all clients post total knee arthroplasty. Choice D is incorrect as applying heat to the incision site can increase the risk of infection.

Correct Answer: C

Rationale: The correct initial action when a patient presents with chest pain is to obtain an ECG. This helps assess the heart's electrical activity and determine the cause of chest pain. Administering aspirin or oxygen therapy may be necessary later based on the ECG findings, but obtaining an ECG is the priority to evaluate the cardiac status. Surgery preparation is not the initial action for chest pain and should only be considered after a thorough assessment.

Correct Answer: D

Rationale: The correct answer is D. Urinary output greater than fluid intake could indicate diabetes insipidus, a complication following hypophysectomy. Diabetes insipidus is characterized by excessive urination and extreme thirst due to inadequate levels of antidiuretic hormone (ADH). Options A, B, and C are all expected findings in the immediate postoperative period following a hypophysectomy. A Glasgow Coma Scale score of 15 indicates the highest level of consciousness, blood drainage on the initial dressing is a common finding after surgery, and dry mouth can be a side effect of anesthesia and surgical procedures.

Correct Answer: B

Rationale: The correct answer is B: 'Avoid lying down after meals.' This instruction is important for clients with GERD to prevent acid reflux. Lying down after meals can worsen GERD symptoms by allowing stomach acid to flow back into the esophagus. Choices A, C, and D are incorrect. Choice A is incorrect because lying flat after meals can increase the risk of acid reflux. Choice C is incorrect because hot liquids may aggravate GERD symptoms. Choice D is incorrect because consuming a high-carbohydrate snack at bedtime can also trigger acid reflux in individuals with GERD.
