ATI RN Exit Exam Quizlet

Correct Answer: A

Rationale: The correct answer is to monitor aPTT. Activated Partial Thromboplastin Time (aPTT) is crucial to monitor when a patient is receiving heparin therapy. Heparin works by potentiating antithrombin III, leading to the inhibition of thrombin and factor Xa. Monitoring aPTT helps ensure the patient is within the therapeutic range for heparin, reducing the risk of bleeding complications. Monitoring INR (Choice B) is more relevant for patients on warfarin therapy. Monitoring potassium (Choice C) and sodium levels (Choice D) is important but not specific to heparin therapy.

Correct Answer: B

Rationale: The correct answer is B. A high PaCO2 level (55 mm Hg) in a client with chronic emphysema suggests respiratory acidosis, which requires further treatment. In chronic emphysema, impaired gas exchange leads to elevated carbon dioxide levels in the blood. Option A (PaO2 level of 89 mm Hg) is near the normal range and does not indicate immediate treatment. Option C (HCO3 level of 25 mEq/L) and option D (pH level of 7.37) are within normal limits and do not suggest the need for further treatment in this context.

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: B

Rationale: The correct answer is B. An elevated creatinine level, such as 1.8, suggests potential kidney dysfunction, requiring further assessment. Sodium level within normal limits (135-145 mEq/L), hemoglobin level of 15 g/dL, and potassium level of 4.2 mEq/L are all within normal ranges and do not indicate immediate concerns. Therefore, they do not require further evaluation at this time.

Correct Answer: A

Rationale: The best intervention for a patient with suspected deep vein thrombosis (DVT) is to administer anticoagulants. Anticoagulants help prevent further clot formation and reduce the risk of complications such as pulmonary embolism. Applying compression stockings can help manage symptoms but does not address the underlying issue of clot formation. Encouraging ambulation is beneficial for overall circulation but may not be sufficient to treat DVT. Monitoring oxygen saturation is important, but it is not the primary intervention for suspected DVT.
