Final answer:
The nurse should prepare for chest tube insertion, apply supplemental oxygen, and consider placing the adolescent in a supine position if appropriate. Consent for a pericardiocentesis and administering levalbuterol are not indicated based on the given clinical scenario.
Step-by-step explanation:
A nurse in a pediatric emergency department is planning care for an adolescent who has been in a motor-vehicle crash.
The patient's symptoms suggest a pneumothorax based on the findings of diminished breath sounds in the left lung and air present in the left pleural space on the chest x-ray. The actions the nurse should plan to take include:
Prepare for chest tube insertion: To remove the air from the pleural space and allow the lung to re-expand.
Apply supplemental oxygen: To treat the hypoxemia as indicated by the oxygen saturation of 94% on room air.
Place the adolescent in a supine position: Only if it does not cause further respiratory distress, and if not contraindicated based on the patient's condition.
Obtaining consent for a pericardiocentesis is not supported by the information provided, as there is no evidence of a pericardial effusion or cardiac tamponade at this time.
Administering a levalbuterol metered dose inhaler may be appropriate for bronchospasm or asthma but is not indicated here based solely on the provided information.
