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: Pallor. Pallor, which is paleness of the skin, is a common sign of anemia due to a decreased number of red blood cells or hemoglobin levels. This results in reduced oxygen-carrying capacity, leading to the paleness of the skin. Choice A, increased appetite, is not typically associated with anemia. Choice C, tachycardia (increased heart rate), can be present in anemia as the body compensates for decreased oxygenation. Choice D, hypertension (high blood pressure), is not a common finding in anemia; instead, low blood pressure may be observed due to decreased blood volume.

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.

Correct Answer: A

Rationale: The correct answer is to monitor aPTT (activated partial thromboplastin time) when a patient is receiving heparin therapy. aPTT monitoring is essential for assessing the therapeutic effectiveness of heparin, ensuring the patient is within the desired therapeutic range to prevent both clotting and bleeding. Monitoring platelet count (Choice B) is important for assessing for heparin-induced thrombocytopenia but is not the primary monitoring parameter for heparin therapy. Monitoring sodium levels (Choice C) and calcium levels (Choice D) are not directly related to assessing the therapeutic effectiveness or potential side effects of heparin therapy.

Correct Answer: B

Rationale: The correct instruction the nurse should include is to advise the client to avoid consuming grapefruit juice when taking statin medication. Grapefruit juice can interfere with the metabolism of statins, leading to an increased risk of adverse effects. Taking the medication on an empty stomach (Choice A) or in the morning (Choice D) is not specifically necessary for statins. While increasing dietary fiber intake (Choice C) is generally beneficial for health, it is not a specific instruction related to taking statin medication.
