A client presents to the emergency department complaining of sudden onset of palpitations and chest pain. After assessment, the nurse notes the client to be diaphoretic, skin is cool to touch, BP is 80/40 mm Hg. Resp 26 and Sats of 89% [see image]. The nurse anticipates an order for which of the following interventions?

Syncronized cardioversion
Adenosine infusion over 30 minutes
Immediate defibrillation
Vagal manuevers
The Correct Answer is A
A. Synchronized cardioversion: Synchronized cardioversion is indicated for unstable supraventricular tachycardia (SVT), especially when the client shows signs of hemodynamic instability, such as hypotension, altered mental status, or chest pain. This intervention delivers a timed shock to restore normal rhythm, prioritizing the client's immediate stabilization.
B. Adenosine infusion over 30 minutes: Adenosine is typically administered as a rapid intravenous push to terminate SVT by temporarily blocking atrioventricular nodal conduction. However, this client is unstable, and synchronized cardioversion is the preferred intervention in cases of hemodynamic compromise.
C. Immediate defibrillation: Defibrillation is used for life-threatening arrhythmias like ventricular fibrillation or pulseless ventricular tachycardia. In this case, the rhythm is SVT, and the client is not in cardiac arrest, so defibrillation is inappropriate.
D. Vagal maneuvers: Vagal maneuvers, such as carotid sinus massage or the Valsalva maneuver, are first-line interventions for stable SVT. However, in unstable clients with severe symptoms or hemodynamic compromise, these measures are insufficient, and synchronized cardioversion is urgently required.

Correct Answer is D
Explanation
A) Assess the client's potassium level:
While electrolyte imbalances, including low potassium, can contribute to symptoms like restlessness or muscle weakness, it is not the first priority in a client with COPD who suddenly becomes restless and anxious. Restlessness and anxiety in this context are more likely to be due to hypoxia (low oxygen levels), hypercapnia (high carbon dioxide levels), or respiratory distress.
B) Check the client's temperature:
An elevated temperature may indicate an infection, such as pneumonia or a respiratory tract infection, which can exacerbate COPD symptoms. However, in the context of sudden restlessness and anxiety, this is less likely to be the most immediate cause. The primary concern should be addressing the potential respiratory issues, such as hypoxia or acute exacerbation, rather than focusing on fever, unless other signs of infection are present.
C) Increase the client's oxygen flow rate to 15 L/min:
While it is important to ensure adequate oxygenation in a client with COPD, increasing the oxygen flow rate to 15 L/min may not be appropriate, as COPD patients are typically at risk for oxygen-induced hypercapnia. These patients often rely on low levels of oxygen to stimulate breathing, and administering high-flow oxygen can suppress their respiratory drive, potentially worsening carbon dioxide retention.
D) Encourage the client to perform pursed-lip breathing:
Pursed-lip breathing is a highly effective technique for COPD patients to help increase oxygenation and decrease the work of breathing. This technique involves the client breathing in through the nose and exhaling slowly through pursed lips, which helps to keep the airways open longer and facilitates the removal of trapped air in the lungs.
Correct Answer is D
Explanation
A. Hypertension:
Hypertension is not directly related to the rhythm displayed in the image. The rhythm is suggestive of atrial fibrillation (AF), characterized by irregular and chaotic electrical activity, leading to irregular heartbeats. Hypertension can be a risk factor for AF but is not a typical presenting symptom.
B. Indigestion:
Indigestion is a non-specific symptom that may occur in cardiac events like myocardial infarction but is not a hallmark of atrial fibrillation. The rhythm strip does not indicate myocardial ischemia.
C. Eupnea:
Eupnea refers to normal breathing, which is not commonly associated with atrial fibrillation. Clients with AF may experience symptoms such as shortness of breath or fatigue rather than normal, unlabored breathing.
D. Irregular palpitations:
This is the most expected finding. Atrial fibrillation leads to an irregularly irregular pulse, which patients often describe as palpitations. This rhythm strip demonstrates the hallmark chaotic atrial activity and irregular ventricular response seen in AF.
