A nurse is caring for a client who reports heart palpitations. An ECG confirms the client is experiencing ventricular tachycardia (VT). The nurse should anticipate the need for taking which of the following actions?
Elective cardioversion
Defibrillation
CPR
Radiofrequency catheter ablation
The Correct Answer is A
The correct answer is: A. Elective cardioversion
Choice A reason:
Elective cardioversion is a medical procedure that is used to restore a normal heart rhythm in patients experiencing certain types of arrhythmias, including ventricular tachycardia (VT), when they are stable. It involves the delivery of a controlled electric shock to the heart, which is synchronized with the heart's electrical activity to convert the abnormal rhythm back to a normal sinus rhythm. This procedure is typically performed when VT is not causing hemodynamic instability and the patient is not in immediate danger.
Choice B reason:
Defibrillation is an emergency treatment for life-threatening cardiac arrhythmias, particularly ventricular fibrillation (VF) or pulseless ventricular tachycardia. It involves delivering a high-energy electric shock to the heart unsynchronized to the heart's electrical cycle, aiming to reset the heart's electrical state and allow it to reestablish an effective rhythm. In the scenario provided, where the patient is experiencing VT but not VF, defibrillation would not be the first line of action unless the VT deteriorates into VF or the patient becomes pulseless.
Choice C reason:
CPR, or cardiopulmonary resuscitation, is a lifesaving technique useful in many emergencies, including heart attack or near drowning, in which someone's breathing or heartbeat has stopped. In the case of VT, if the patient is conscious and has a pulse, CPR is not indicated. CPR would only be necessary if the patient's heart stops beating (cardiac arrest) as a result of the VT.
Choice D reason:
Radiofrequency catheter ablation is a procedure used to treat some types of arrhythmias, including VT, by destroying the area of heart tissue that is causing the abnormal heart rhythm. This treatment is generally considered when medication is ineffective or not tolerated, or in recurrent VT. It is not typically the first line of treatment in an acute setting where the patient is stable and experiencing VT.

Correct Answer is A
Explanation
The correct answer is: a. Place a black tag on the client’s upper body and attempt to help the next client in need.
Choice A: Place a black tag on the client’s upper body and attempt to help the next client in need.
In mass casualty incidents, the START (Simple Triage and Rapid Treatment) triage system is often used. According to this system, if a patient is apneic (not breathing) and does not resume breathing after repositioning the airway, they are considered deceased or non-salvageable and should be tagged with a black tag. This allows the nurse to focus on other victims who have a higher chance of survival.
Choice B: Start CPR
While starting CPR might seem appropriate in a normal setting, during a mass casualty incident, resources and time are limited. The priority is to save as many lives as possible. Performing CPR on an apneic patient with a weak pulse would take significant time and resources that could be used to help other victims with a higher chance of survival.
Choice C: Place a red tag on the client’s upper body and obtain immediate help from other personnel.
A red tag is used for patients who need immediate care and have a high chance of survival if treated promptly. Since the client remains apneic even after repositioning the airway, they do not meet the criteria for a red tag.
Choice D: Reposition the client’s upper airway a second time before assessing his respirations.
Repositioning the airway a second time is not recommended in the START triage system. If the patient does not resume breathing after the initial repositioning, they are considered non-salvageable.
Correct Answer is D
Explanation
Choice A Reason: This is incorrect. Opioids are not indicated for a client who is emerging from a coma, as they can cause respiratory depression, sedation, and confusion. They may also mask the signs of increased intracranial pressure or neurological deterioration.
Choice B Reason: This is incorrect. Darkening the room may not be helpful for a client who is emerging from a coma, as it may increase their disorientation and agitation. The nurse should provide adequate lighting and orient the client to time, place, and person frequently.
Choice C Reason: This is incorrect. Applying restraints may worsen the restlessness and agitation of a client who is emerging from a coma, as they may perceive them as a threat or a restriction. Restraints may also increase the risk of injury, infection, or skin breakdown. The nurse should use restraints only as a last resort and with a physician's order.
Choice D Reason: This is correct. Reducing stimuli is an appropriate intervention for a client who is emerging from a coma, as it can help calm them and prevent sensory overload. The nurse should limit noise, visitors, and unnecessary procedures, and provide a quiet and comfortable environment.
