Correct Answer: C

Rationale: The correct answer is to medicate the patient with prescribed morphine. A major reason for atelectasis and poor airway clearance in patients after chest surgery is incisional pain, which can worsen with deep breathing and coughing. The priority is to address the incisional pain to facilitate effective coughing and deep breathing, which are essential for clearing the airways and preventing complications. Assisting the patient to sit upright, splinting the patient's chest during coughing, and observing the patient using the incentive spirometer are all appropriate interventions to improve airway clearance, but they should be implemented after addressing the incisional pain with medication.

Correct Answer: C

Rationale: The normal WBC count indicates that the antibiotics have been effective. All the other data suggest that a change in treatment is needed.

Correct Answer: C

Rationale: Patients should continue to cough and deep breathe after discharge. Fatigue is expected for several weeks. The Pneumovax and influenza vaccines can be given at the same time in different arms. Explain that a follow-up chest x-ray needs to be done in 6 to 8 weeks to evaluate resolution of pneumonia.

Correct Answer: A

Rationale: The correct answer is 'Oxygen saturation is 88%.' Following a thoracentesis, oxygen saturation should improve. A saturation of 88% suggests a potential complication like pneumothorax. While the other assessment findings are important, the priority is to address the low oxygen saturation to prevent further complications. High blood pressure and respiratory rate may also need attention, but the immediate concern is the oxygen saturation level. Pain level, though significant for the patient's comfort, takes lower priority compared to the potential life-threatening issue of hypoxia.

Correct Answer: D

Rationale: The patient presents with symptoms indicative of a pulmonary embolism (PE), such as chest pain, difficulty breathing, tachycardia, hypotension, and tachypnea. Elevating the head of the bed to a semi-Fowler's position is the priority to improve ventilation and gas exchange. This intervention should be initiated promptly to optimize oxygenation. Subsequent actions, such as notifying the healthcare provider, preparing for a spiral CT scan, and administering anticoagulant therapy, can follow after the patient's position is adjusted. The spiral CT scan is typically used to confirm the diagnosis of PE, and anticoagulant therapy is initiated upon confirmation of the diagnosis by the healthcare provider. Therefore, the immediate focus is on improving the patient's respiratory status by elevating the head of the bed.
