What is the most critical lab value to monitor for a patient on heparin therapy?

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: A

Rationale: Administering anticoagulants is the most crucial nursing action for a patient experiencing a deep vein thrombosis (DVT). Anticoagulants help prevent further clot formation and reduce the risk of complications such as pulmonary embolism. Encouraging ambulation, applying compression stockings, and monitoring oxygen saturation are important interventions in managing DVT, but administering anticoagulants takes priority as it directly targets the clotting process and prevents clot progression.

Correct Answer: C

Rationale: The correct answer is C because bending at the hips can dislocate the hip joint in clients who have had a total hip arthroplasty. This movement should be avoided to prevent complications post-surgery. Choices A, B, and D are all correct statements for a client who has had a total hip arthroplasty. Avoiding prolonged sitting, crossing legs, and using a raised toilet seat are all appropriate measures to ensure proper healing and prevent complications.

Correct Answer: A

Rationale: The correct answer is to administer anticoagulants. Administering anticoagulants is crucial in the management of deep vein thrombosis (DVT) as it helps prevent the clot from growing larger or dislodging, potentially causing a life-threatening pulmonary embolism. While monitoring oxygen levels, applying compression stockings, and encouraging ambulation are important aspects of DVT management, administering anticoagulants is the most critical intervention to prevent further complications.

Correct Answer: B

Rationale: When administering enoxaparin, it is important to pinch the skin to ensure proper subcutaneous injection. Massaging the injection site after administering the medication is not recommended. Administering the medication at bedtime is not a specific requirement for enoxaparin. Aspirating before injecting the medication is not necessary for subcutaneous injections like enoxaparin.

Correct Answer: A

Rationale: The correct answer is to monitor vital signs post-surgery. Vital signs provide crucial information about a patient's physiological status, helping detect early signs of complications such as shock, bleeding, or infection. Checking the surgical site for bleeding is important but falls secondary to monitoring vital signs, which give a broader overview of the patient's condition. Checking for abnormal breath sounds and skin color are also important assessments, but they are not as immediate and general as monitoring vital signs in detecting various post-surgical complications.

Correct Answer: A

Rationale: The correct answer is A: Wear loose clothing over the radiation site. Clients receiving radiation therapy should wear loose clothing over the treatment area to prevent irritation and promote healing. Choice B is incorrect as scented lotions can irritate the skin during radiation therapy. Choice C is incorrect because ice packs should not be applied to the radiation site as they can exacerbate skin reactions. Choice D is incorrect as exposing the radiation site to sunlight can increase skin damage and should be avoided.

Correct Answer: D

Rationale: The correct answer is D. Warmth and redness in the calf are indicative of a possible deep vein thrombosis (DVT), a serious complication post-surgery that requires immediate attention. Reporting this finding promptly to the provider is crucial for timely intervention. Choices A, B, and C are within normal limits for a postoperative client and do not indicate a potentially life-threatening condition like DVT.

Correct Answer: A

Rationale: The correct answer is to administer oxygen. In a patient experiencing respiratory distress, ensuring adequate oxygenation is the priority. Administering oxygen helps improve oxygen levels, which is crucial for the patient's well-being. Repositioning the patient, administering bronchodilators, or giving IV fluids are important interventions in certain situations, but when a patient is in respiratory distress, providing oxygen takes precedence over other actions.
