A nurse in the emergency department is caring for a client who has extensive partial and full-thickness burns of the head, neck, and chest. While planning the client's care, the nurse should identify which of the following risks as the priority for assessment and intervention?
Infection
Airway obstruction
Paralytic ileus
Fluid imbalance
The Correct Answer is B
Choice A Reason: Infection is a serious complication of burn injuries, but not the priority risk for assessment and intervention. The nurse should monitor the client's wound healing, temperature, white blood cell count, and signs of sepsis, and administer antibiotics as prescribed. However, these measures are secondary to ensuring adequate oxygenation and ventilation.
Choice B Reason: Airway obstruction is the priority risk for assessment and intervention for a client who has burns of the head, neck, and chest. The nurse should assess the client's airway patency, respiratory rate, oxygen saturation, breath sounds, and signs of respiratory distress, such as stridor, wheezes, or cyanosis. The nurse should also provide humidified oxygen, suction secretions, elevate the head of the bed, and prepare for endotracheal intubation if needed. Airway obstruction can occur due to edema, inflammation, or inhalation injury of the upper airway, and can quickly lead to hypoxia, respiratory failure, and death.
Choice C Reason: Paralytic ileus is a potential complication of burn injuries, but not the priority risk for assessment and intervention. The nurse should assess the client's bowel sounds, abdominal distension, nausea, vomiting, and stool output, and administer fluids, electrolytes, and nutritional support as prescribed. However, these measures are secondary to ensuring adequate oxygenation and ventilation.
Choice D Reason: Fluid imbalance is another potential complication of burn injuries, but not the priority risk for assessment and intervention. The nurse should assess the client's fluid status, urine output, vital signs, weight, and serum electrolytes, and administer intravenous fluids as prescribed. However, these measures are secondary to ensuring adequate oxygenation and ventilation.

Correct Answer is C
Explanation
Choice A Reason: This choice is incorrect because inserting a central line is not a priority action for a client who has a sucking chest wound. A central line is a catheter that is inserted into a large vein in the neck, chest, or groin to administer fluids, medications, or blood products. It may be indicated for clients who have hypovolemia, sepsis, or shock, but it does not address the underlying cause of the client's respiratory distress.
Choice B Reason: This choice is incorrect because removing the dressing to inspect the wound may worsen the client's condition. A sucking chest wound is an open wound in the chest wall that allows air to enter and exit the pleural cavity with each breath. This creates a positive pressure in the pleural space that collapses the lung on the affected side and shifts the mediastinum to the opposite side, impairing the ventilation and circulation of both lungs. Therefore, the nurse should apply an occlusive dressing that covers three sides of the wound and allows air to escape but not enter the pleural cavity. Removing the dressing may allow more air to enter and increase the risk of tension pneumothorax, which is a life-threatening complication.
Choice C Reason: This choice is correct because administering oxygen via nasal cannula may help to improve the client's oxygenation and ventilation. A nasal cannula is a device that delivers oxygen through two prongs that fit into the nostrils. It can provide oxygen at low flow rates (1 to 6 L/min) and low concentrations (24 to 44 percent). The nurse should monitor the client's respiratory rate, pulse oximetry, and arterial blood gases to assess the effectiveness of oxygen therapy.
Choice D Reason: This choice is incorrect because raising the foot of the bed to a 90° angle may worsen the client's respiratory distress. This position may increase the pressure on the diaphragm and reduce the lung expansion. It may also decrease the venous return and cardiac output, leading to hypotension and shock. Therefore, the nurse should position the client in a semi-Fowler's position (30 to 45° angle) or high-Fowler's position (60 to 90° angle) to facilitate breathing and prevent further complications.
Correct Answer is D
Explanation
Choice A Reason: This choice is incorrect because flatened neck veins are not a sign of cardiac tamponade. Cardiac tamponade is a condition in which fluid accumulates in the pericardial sac that surrounds the heart, causing compression and impaired filling of the heart chambers. This leads to reduced cardiac output and hypotension. One of the manifestations of cardiac tamponade is distended neck veins due to increased venous pressure and impaired venous return.
Choice B Reason: This choice is incorrect because bradycardia is not a sign of cardiac tamponade. Bradycardia is a condition in which the heart rate is slower than normal (less than 60 beats per minute). It may be caused by various factors such as vagal stimulation, medication side effects, hypothyroidism, or sinus node dysfunction. It may cause symptoms such as fatigue, dizziness, or syncope, but it does not indicate cardiac tamponade.
Choice C Reason: This choice is incorrect because sudden lethargy is not a specific sign of cardiac tamponade. Lethargy is a condition in which the person feels tired, sluggish, or drowsy. It may be caused by various factors such as sleep deprivation, depression, infection, anemia, or hypoglycemia. It may affect the person's mental and physical performance, but it does not indicate cardiac tamponade.
Choice D Reason: This choice is correct because muffled heart sounds are a sign of cardiac tamponade. Muffled heart sounds are heart sounds that are fainter or softer than normal due to reduced transmission of sound waves through fluid-filled pericardial sac. They may indicate that the heart function is compromised by cardiac tamponade and require immediate intervention such as pericardiocentesis (removal of fluid from pericardial sac).
