When assessing a patient who has just arrived after an automobile accident, the emergency department nurse notes tachycardia and absent breath sounds over the right lung. For which intervention will the nurse prepare the patient?

Correct Answer: D

Rationale: The patient's history and absent breath sounds suggest a right-sided pneumothorax or hemothorax, which will require treatment with a chest tube and drainage. Emergency pericardiocentesis is not indicated as the patient's symptoms are not suggestive of cardiac tamponade. Stabilization of the chest wall with tape would not address the underlying issue of a potential pneumothorax or hemothorax. Administration of an inhaled bronchodilator is not appropriate in this scenario as the patient is not exhibiting signs of asthma or bronchoconstriction. Therefore, the correct intervention for this patient is the insertion of a chest tube with a chest drainage system to address the potential pneumothorax or hemothorax.

Correct Answer: C

Rationale: After a pneumonectomy, frequent deep breathing and coughing are essential to prevent atelectasis and promote gas exchange. Patients are typically positioned on the surgical side to aid in gas exchange. Early mobilization is crucial to reduce the risk of postoperative complications such as pneumonia and deep vein thrombosis. While chest tubes may or may not be placed in the surgical space, if used, they are clamped and only adjusted by the surgeon to manage serosanguineous fluid accumulation. Overfilling of the chest cavity can compromise remaining lung function and cardiovascular status. Chest x-rays are useful for monitoring fluid volume and space postoperatively. Therefore, the correct postoperative care instruction for the patient undergoing a left pneumonectomy is the frequent use of an incentive spirometer. Choices A, B, and D are incorrect as positioning on the right side, bed rest for the first 24 hours, and continuous chest tube drainage are not standard postoperative care practices for patients undergoing pneumonectomy.

Correct Answer: A

Rationale: To evaluate the effectiveness of therapies for cor pulmonale and right-sided heart failure, observing for distended neck veins would be the most appropriate assessment. Cor pulmonale is characterized by right ventricular failure due to pulmonary hypertension, leading to clinical manifestations such as peripheral edema, jugular venous distention, and right upper-quadrant abdominal tenderness. These signs indicate increased central venous pressure and right heart strain, which can be assessed by observing for distended neck veins. Auscultating for crackles in the lungs is more indicative of left-sided heart failure rather than right-sided heart failure. Heaves or thrills over the heart are not typically associated with cor pulmonale. Reviewing hemoglobin and hematocrit values may show elevations due to chronic hypoxemia and polycythemia in cor pulmonale, but these values alone do not directly evaluate the immediate effectiveness of the prescribed therapies on the patient's condition.

Correct Answer: B

Rationale: The correct answer is for the patient to report decreased exertional dyspnea. In idiopathic pulmonary arterial hypertension (IPAH), exertional dyspnea is a significant symptom indicating disease severity. Improvement in this symptom suggests that the medication, nifedipine, is effective in managing the condition. While nifedipine can affect blood pressure (choice A) and heart rate (choice C), these parameters are not specific indicators for monitoring IPAH improvement. Choice D, clear lung fields on the chest x-ray, does not directly correlate with the effectiveness of therapy for IPAH. Therefore, the most relevant assessment to monitor improvement in a patient with IPAH receiving nifedipine is a decrease in exertional dyspnea.

Correct Answer: B

Rationale: The correct action for the nurse to take in preparing a patient for a thoracentesis is to position the patient sitting upright on the edge of the bed and leaning forward. This position helps fluid accumulate at the lung bases, making it easier to locate and remove. Sedation is not usually required for a thoracentesis, so starting an IV line for sedative drugs is unnecessary. Additionally, there are no restrictions on oral intake before the procedure since the patient is not sedated or unconscious. A large collection device to hold 2 to 3 liters of pleural fluid at one time is excessive as usually only 1000 to 1200 mL of pleural fluid is removed to avoid complications like hypotension, hypoxemia, or pulmonary edema. Therefore, the correct choice is to position the patient upright for the procedure.
