A client has been treated for uncontrolled atrial fibrillation with cardioversion. Following the cardioversion, which assessment finding indicates to the nurse that the desired outcome was achieved?
Normal sinus rhythm (NSR) at 84 beats/minute.
Regular rhythm with consistent pacemaker capture.
Return of elevated ST segment to the baseline.
Increased frequency of QRS complexes.
The Correct Answer is A
A. Normal sinus rhythm (NSR) at 84 beats/minute. The goal of cardioversion for atrial fibrillation (AFib) is to restore a normal sinus rhythm (NSR). NSR indicates that the atria and ventricles are depolarizing in a coordinated manner, reducing the risk of thromboembolism, stroke, and hemodynamic instability. A heart rate of 84 beats/minute is within the normal range, confirming the success of the procedure.
B. Regular rhythm with consistent pacemaker capture. Cardioversion is used to restore normal rhythm in AFib, not to manage pacemaker function. A pacemaker is not part of standard AFib cardioversion unless the client has underlying conduction issues requiring pacing.
C. Return of elevated ST segment to the baseline. ST elevation suggests acute myocardial infarction (MI), which is unrelated to atrial fibrillation or cardioversion. Cardioversion does not treat ST elevation or myocardial ischemia, making this an incorrect indicator of success.
D. Increased frequency of QRS complexes. An increase in QRS frequency suggests tachycardia, which would indicate treatment failure rather than success. The goal of cardioversion is to restore a normal, controlled heart rate and rhythm, not to increase the number of ventricular contractions.

Correct Answer is ["A","B","C","D"]
Explanation
A. Allow the family to touch and talk to the client. Family presence can provide emotional support for both the client and loved ones. Even though the client is sedated and has a low GCS, familiar voices and touch may reduce stress and anxiety. Allowing family interaction fosters comfort and connection during a critical time.
B. Reassess the client's vascular access. Maintaining secure and functional vascular access is essential for administering fluids, medications, and emergency interventions. Before transport, the nurse should confirm IV patency, ensure secure connections, and assess for signs of infiltration or malfunction. Trauma patients may require additional or larger bore IV access for fluid resuscitation or transfusion.
C. Assess neurological vital signs every 15 minutes. Frequent neurological assessments are crucial in head trauma patients with a low GCS to monitor for signs of worsening intracranial pressure, cerebral edema, or herniation. Changes in pupil response, motor function, or vital signs may indicate neurological deterioration requiring urgent intervention. Monitoring trends over time is necessary for early detection of complications.
D. Administer ophthalmic ointment. Clients with a low GCS often have impaired blinking, placing them at risk for corneal abrasions and dryness. Applying ophthalmic lubricant or artificial tears protects the cornea from injury and promotes eye health. Preventing exposure keratitis is essential in unconscious or sedated clients to avoid long-term ocular damage.
E. Apply soft bilateral wrist restraints for transport. Restraints are unnecessary because the client is sedated, intubated, and has a GCS of 6, meaning they cannot attempt self-extubation or interfere with care. Restraints should only be used if the client demonstrates a risk of harm. Standard transport protocols prioritize sedation and safety measures over restraints unless specifically required.
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.
