Which action by the nurse will help reduce the risk of venous thromboembolism (VTE) in a postoperative patient?

Correct Answer: A

Rationale: The correct answer is to encourage early ambulation and leg exercises. By promoting early ambulation and leg exercises, blood flow is enhanced, reducing the risk of venous thromboembolism (VTE) in postoperative patients. Choice B, applying compression stockings, helps prevent VTE but is not as effective as early ambulation and exercises. Choice C, administering anticoagulants, is important in VTE prevention but does not directly address improving circulation through physical activity. Choice D, elevating the patient's legs, may be beneficial for circulation in specific cases but is not as effective in preventing VTE as early ambulation and leg exercises.

Correct Answer: C

Rationale: In the context of chronic pain management, the most concerning finding is when the patient's pain persists despite medication. This suggests inadequate pain control or the need for a re-evaluation of the treatment plan. Choices A, B, and D are not as concerning in this scenario. A pain level of 6 on a scale of 0 to 10 is moderate and may be manageable with appropriate interventions. Patients with chronic pain can sometimes lie still due to pain or other reasons, and anxiety and restlessness are common in individuals with pain conditions but may not necessarily indicate a critical issue like uncontrolled pain.

Correct Answer: A

Rationale: The correct answer is to maintain the patient's oxygen saturation above 90% when caring for a patient with COPD. In COPD, impaired gas exchange leads to decreased oxygen levels in the blood. By ensuring oxygen saturation remains above 90%, healthcare providers can prevent hypoxia and its complications. Administering bronchodilators as prescribed (Choice B) is an important intervention in managing COPD symptoms, but it is not the primary goal. Improving the patient's nutritional intake (Choice C) and encouraging the patient to limit physical activity (Choice D) are also essential aspects of COPD management, but they are not the primary goal when caring for a patient with this condition.

Correct Answer: A

Rationale: The correct answer is to check the patient's heart rate before administering digoxin. Digoxin is a medication that primarily affects cardiac function. Monitoring the heart rate is crucial because digoxin can cause arrhythmias or worsen existing heart rhythm abnormalities. Assessing blood pressure may also be important but is secondary to evaluating the heart rate when administering digoxin. Ensuring the patient has eaten before administration is not directly related to the safe administration of digoxin. Monitoring the patient's weight is not a priority action before administering digoxin.

Correct Answer: B

Rationale: The correct answer is B: "Ensure the chest tube is connected to a closed drainage system." This is a critical nursing action when managing a patient with a chest tube because it is essential for proper drainage and to prevent complications such as air leaks or infections. Option A is incorrect because keeping the chest tube clamped at all times would prevent proper drainage and could lead to complications. Option C is incorrect as emptying the chest tube drainage system should be done based on assessment findings rather than a fixed time interval. Option D is incorrect because disconnecting the chest tube when the patient is ambulating can lead to complications like a pneumothorax.
