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.

Correct Answer: C

Rationale: The correct answer is C: 'Wear compression stockings daily.' Wearing compression stockings is essential after knee surgery to prevent venous stasis and reduce the risk of blood clots. Choice A is incorrect as crossing legs when sitting can increase the risk of blood clots. Choice B is incorrect because performing range-of-motion exercises every 4 hours may not be suitable for all clients post total knee arthroplasty. Choice D is incorrect as applying heat to the incision site can increase the risk of infection.

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: Tracheal deviation is the correct finding to report to the provider. It can indicate a pneumothorax, which is a serious complication following a thoracentesis that requires immediate attention. Oxygen saturation of 96% is within the normal range and does not indicate an immediate issue. A pain level of 4 on a scale of 0 to 10 is subjective and may not be related to a serious complication. A temperature of 37.4°C (99.3°F) is slightly elevated but not a priority over tracheal deviation in this context.

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.
