An adult who fell 20 feet (6 meters) from a tree is admitted to the intermediate intensive care unit with a fractured femur. When the cardiac monitor alarms, the nurse finds the client has no palpable carotid pulse and no spontaneous respiration, however, the cardiac monitor displays a sinus rhythm. Which intervention should the nurse implement?

View the rhythm in another chest lead.

Begin chest compressions at a rate of 120 times a minute.

Auscultate all chest fields for muffled lung sounds.

Observe for swelling at the fracture site.

Answer and Explanation

The Correct Answer is B

A. View the rhythm in another chest lead. While verifying the rhythm in another lead may help confirm the accuracy of the monitor, it does not address the immediate absence of a pulse and respirations. The client is in pulseless electrical activity (PEA), which requires immediate intervention rather than rhythm verification.
B. Begin chest compressions at a rate of 120 times a minute. The client has no palpable carotid pulse and no spontaneous respirations despite a sinus rhythm on the monitor, indicating pulseless electrical activity (PEA). PEA is a form of cardiac arrest where the heart shows electrical activity but fails to generate effective circulation. Immediate high-quality chest compressions are essential to maintain perfusion while addressing the underlying cause, such as hypovolemia or tension pneumothorax.
C. Auscultate all chest fields for muffled lung sounds. While assessing for muffled lung sounds may help detect conditions such as tension pneumothorax or hemothorax, it should not delay the initiation of CPR. Once compressions are started, the underlying cause of PEA can be investigated.
D. Observe for swelling at the fracture site. Swelling at the fracture site may indicate bleeding or compartment syndrome, but assessing the fracture should not take priority over initiating CPR. If hemorrhage is suspected as a cause of PEA, rapid fluid resuscitation should be initiated after starting chest compressions.

Correct Answer is B

Explanation

A. Degree of pain using a 10-point scale. Pain assessment is important, but it is not the priority in an emergency trauma situation. Clients involved in motor vehicle collisions (MVCs) without a helmet are at high risk for life-threatening injuries, including hemorrhage and shock. The nurse must first assess vital signs to determine hemodynamic stability.
B. Pulse and blood pressure. The primary concern in trauma patients is circulation and perfusion. Assessing pulse and blood pressure helps determine if the client is experiencing shock, hemorrhage, or traumatic brain injury (TBI)-related autonomic dysfunction. In trauma resuscitation, the ABCs (Airway, Breathing, Circulation) guide assessment priorities, making circulatory status the first concern after ensuring airway patency.
C. Balance and coordination. A neurological assessment for balance and coordination is not a priority in a critically injured trauma patient. Severe injuries, including intracranial hemorrhage, cervical spine trauma, or internal bleeding, must be ruled out before assessing fine motor function.
D. Bilateral pupillary reaction to light. Pupillary response is part of a neurological assessment and is crucial in identifying traumatic brain injury. However, vital signs must be assessed first to determine hemodynamic stability, as untreated shock or hemorrhage can lead to rapid deterioration or death.

A. Prepare for oral intubation. B. Apply leg compression hose. C. Maintain head of bed at 45°. D. Administer an anticoagulant.

Correct Answer is A

Explanation

A. Prepare for oral intubation. The client is in severe respiratory distress with oxygen saturation at 88% despite receiving 100% oxygen via a nonrebreather mask. This suggests respiratory failure, likely due to a pulmonary embolism (PE), a known complication following bariatric surgery. Immediate intubation and mechanical ventilation are necessary to prevent further hypoxia and respiratory collapse.
B. Apply leg compression hose. While deep vein thrombosis (DVT) prophylaxis is essential for postoperative bariatric patients, it is not the priority in an acute emergency. Compression devices help prevent clots but do not treat an existing life-threatening pulmonary embolism.
C. Maintain head of bed at 45°. Elevating the head of the bed can help with breathing, but it will not significantly improve oxygenation in a client already failing on 100% oxygen. The priority is to secure the airway with intubation to provide controlled ventilation.
D. Administer an anticoagulant. Anticoagulation is a key treatment for pulmonary embolism, but it does not immediately improve oxygenation or stabilize respiratory function. In a hemodynamically unstable client with severe hypoxia, securing the airway takes priority before initiating anticoagulation therapy.
