Chapter 34: Problem 823

The nurse is caring for a client when the cardiac monitor shows that cardiac pattern has changed from a normal sinus rhythm. QRSs are now widened and bizarre at a rate of 160 beats per minute. The client begins complaining of being dizzy. Which is the nurse's immediate action? A. Call a code B. Administer a precordial thump C. Give Lidocaine 50-100 mG. IV push D. Assess the client's vital signs

Short Answer

Expert verified
D. Assess the client's vital signs

Step by step solution

01

- Understand the Symptoms

Recognize that the client鈥檚 cardiac monitor shows a widened and bizarre QRS complex at a rapid rate of 160 beats per minute, which indicates a potential ventricular tachycardia. The additional symptom of dizziness suggests the altered rhythm is affecting the client鈥檚 hemodynamic stability.
02

- Determine Immediate Needs

Identify that immediate action is crucial due to the potentially life-threatening nature of the arrhythmia. The widened QRS complexes are indicative of a serious condition requiring prompt intervention.
03

- Evaluate the Options

Consider the available options for immediate intervention: A. Call a code B. Administer a precordial thump C. Give Lidocaine 50-100 mg IV push D. Assess the client's vital signs. Evaluate each action based on its appropriateness for addressing the situation.
04

- Select the Most Appropriate Action

Option D, Assess the client's vital signs, is the immediate action the nurse should take. Ensuring the client's vital signs are stable provides critical information on the patient's current state before proceeding with further interventions.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

ventricular tachycardia
Ventricular tachycardia (VT) is a type of cardiac arrhythmia characterized by a fast heart rate that originates in the ventricles. The QRS complexes become wide and bizarre, typically greater than 120 milliseconds. This condition is dangerous because it can quickly deteriorate into more severe arrhythmias like ventricular fibrillation. The heart's ability to effectively pump blood is compromised, leading to symptoms such as dizziness, chest pain, and in severe cases, loss of consciousness and cardiac arrest. Immediate intervention is crucial to prevent these severe outcomes.
hemodynamic stability
Hemodynamic stability refers to the balance and stability of blood flow within the cardiovascular system. When a patient experiences ventricular tachycardia, the rapid heart rate can cause the heart to pump blood less efficiently. This leads to decreased cardiac output and can result in symptoms like low blood pressure (hypotension), dizziness, or fainting. In the scenario provided, assessing vital signs is key in determining hemodynamic stability. This includes measuring pulse rate, blood pressure, respiratory rate, and oxygen saturation. Quick assessment helps in deciding the next steps for intervention like medication administration or advanced life support measures.
cardiac arrhythmia assessment
Cardiac arrhythmia assessment is a critical skill in emergency nursing. Arrhythmias can range from benign to life-threatening. In the case of ventricular tachycardia, as indicated by the bizarre and wide QRS complexes on the cardiac monitor, recognizing this change promptly is vital for appropriate intervention. Initial assessment steps generally include:
  • Evaluating the patient's consciousness and complaints (e.g., dizziness).
  • Checking vital signs like blood pressure and pulse.
  • Observing and interpreting the cardiac monitor's readings.
By assessing these factors, healthcare providers can ensure the most appropriate and timely response to stabilize the patient and prevent further complications.
