The nurse notices ventricular tachycardia on the heart monitor. When the patient is assessed, the patient is found to be unresponsive with no pulse. The nurse should:

A. Beta-blockers, such as metoprolol or esmolol, are commonly used to slow the ventricular rate in certain tachyarrhythmias like atrial fibrillation or atrial flutter, especially when the patient is hemodynamically stable. However, in this scenario, the patient is symptomatic with a very high heart rate (165 bpm), which may indicate compromised cardiac output. Symptoms may include hypotension, chest pain, shortness of breath, or altered mental status. In unstable patients, beta-blockers are too slow to reverse the hemodynamic instability, making emergent cardioversion the appropriate first-line treatment.

B. Pacemakers are indicated for bradycardia or high-grade heart block, not tachyarrhythmias. Using a pacemaker in a patient with supraventricular tachycardia (SVT) or other narrow complex tachycardias would not correct the rapid heart rate and may worsen patient condition.

C. This patient demonstrates narrow complex tachycardia (likely SVT) that is regular and rapid, with symptoms indicating hemodynamic instability. According to ACLS (Advanced Cardiac Life Support) guidelines, synchronized electrical cardioversion is indicated for unstable tachyarrhythmias to restore sinus rhythm promptly. Synchronized cardioversion ensures the electrical shock is delivered during the R wave to avoid inducing ventricular fibrillation. Emergent cardioversion is prioritized over medications when a patient is unstable because it immediately restores cardiac output and perfusion.

D. Atropine is an anticholinergic drug used primarily for bradycardia to increase heart rate by blocking vagal stimulation. Administering atropine to a patient with tachycardia would be inappropriate and could further increase heart rate, worsening myocardial oxygen demand and precipitating ischemia or hemodynamic collapse.

A. QSEN focuses on preparing nurses with knowledge, skills, and attitudes to improve patient safety and quality of care. While relevant to overall safety, it does not specifically guide matching nurse competencies to patient acuity in assignments.

B. These goals, established by The Joint Commission, provide specific safety standards for areas such as medication administration, infection control, and patient identification. They do not address individualized nurse-patient assignments based on skill and patient acuity.

C. The Synergy Model links patient needs with nurse competencies, emphasizing that patient outcomes are optimized when the nurse’s experience, expertise, and certification match patient complexity and acuity. In this scenario, the most experienced nurse is assigned the most critically ill patient, while the less experienced nurse cares for more stable patients, reflecting synergy between patient needs and nurse competencies.

D. Crew resource management focuses on team communication, decision-making, and error reduction, originally in aviation and applied in healthcare to improve safety. It does not specifically guide nurse-patient assignment based on competency.
