ATI RN Exit Exam

Correct Answer: C

Rationale: The correct answer is C: aPTT. Monitoring the activated partial thromboplastin time (aPTT) is crucial when a client is receiving heparin therapy. The aPTT reflects the clotting time and helps assess the effectiveness of heparin in preventing clot formation. Keeping the aPTT within the therapeutic range ensures that the medication is working optimally. Choices A, B, and D are incorrect because serum potassium, platelets, and INR are not direct indicators of heparin's effectiveness or therapeutic range.

Correct Answer: A

Rationale: Administering oxygen is the most appropriate initial response to a patient experiencing confusion after surgery. Confusion can be a sign of hypoxia, which is inadequate oxygen supply to the brain. Administering oxygen helps ensure that the patient is getting enough oxygen, addressing a potential cause of the confusion. Repositioning the patient, encouraging deep breathing exercises, or performing a neurological exam may be necessary depending on the situation, but addressing potential hypoxia should be the priority in a confused post-operative patient.

Correct Answer: C

Rationale: Corrected Rationale: Redness and warmth are classic signs of inflammation, which are commonly seen in clients with deep vein thrombosis (DVT). These findings indicate increased blood flow and temperature in the affected area. Pain in the right lower extremity (Choice A) is not expected in a client with DVT affecting the left lower extremity. Cold skin (Choice B) is not a typical finding in DVT; instead, warmth is more indicative of inflammation. Shiny skin (Choice D) is not a common characteristic of DVT; rather, the skin may appear red, swollen, and warm due to the inflammatory process.

Correct Answer: B

Rationale: The correct answer is B. Instructing the client to hold their breath for 10 seconds after inhaling the medication allows it to reach deeper into the lungs for maximum effectiveness. Choice A is incorrect because taking one puff every 5 minutes may lead to overuse of the medication. Choice C is incorrect as shaking the inhaler for only 2 seconds may not provide adequate mixing of the medication. Choice D is incorrect because exhaling forcefully after each puff may reduce the amount of medication that reaches the lungs.

Correct Answer: A

Rationale: In a client with pericarditis, the priority finding is a paradoxical pulse. This is a crucial sign of cardiac tamponade, a life-threatening complication of pericarditis where fluid accumulates in the pericardial sac, causing compression of the heart. A paradoxical pulse is an exaggerated decrease in systolic blood pressure (>10 mmHg) during inspiration. Prompt recognition and intervention are essential to prevent hemodynamic instability and cardiac arrest. Dependent edema (choice B) is not typically associated with pericarditis. Pericardial friction rub (choice C) is a common finding in pericarditis but does not indicate the urgency of intervention as a paradoxical pulse. Substernal chest pain (choice D) is a classic symptom of pericarditis but is not as critical as a paradoxical pulse in the context of assessing for complications.
