ATI RN Exit Exam Quizlet

Correct Answer: C

Rationale: Encouraging the client to ambulate as soon as possible is essential in preventing complications like deep vein thrombosis post knee arthroplasty. While keeping the affected leg elevated and applying ice packs can be beneficial in certain situations, early ambulation takes precedence in this case. Performing range-of-motion exercises hourly may not be necessary and could potentially cause more harm than good if not done correctly or excessively.

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: B

Rationale: The correct answer is B: Perform weight-bearing exercises. Weight-bearing exercises are essential for preventing further bone loss and improving bone density in clients with osteoporosis. Calcium supplements alone may not be sufficient to prevent bone loss without adequate physical activity. Option C, 'Avoid weight-bearing exercises,' is incorrect as these exercises are beneficial for bone health. Option D, 'Limit intake of high-phosphorus foods,' is not directly related to preventing further bone loss in osteoporosis.

Correct Answer: C

Rationale: In a mass casualty situation, a client with hypovolemic shock should be the priority as they require immediate intervention to restore fluid volume and prevent further deterioration. Hypovolemic shock can lead to organ failure and death if not addressed promptly. While clients with other severe conditions like massive head trauma, full-thickness burns, or an open fracture also need urgent care, hypovolemic shock directly threatens the client's life due to inadequate circulating blood volume. Therefore, stabilizing the client with indications of hypovolemic shock takes precedence over others in this scenario.

Correct Answer: A

Rationale: Administering oxygen is the initial step in managing chest pain. Oxygen helps improve oxygenation levels in the blood, which is crucial in cases of chest pain. Repositioning the patient, providing pain relief, or administering nitroglycerin may be necessary steps depending on the underlying cause, but administering oxygen takes precedence as it addresses the primary concern of oxygen supply to the body during chest pain.
