After exercising, a client is hooked up to a cardiac monitor. The rhythm below is noted. How should the nurse document this rhythm?
Junctional tachycardia
Sinus tachycardia
Atrial flutter
Ventricular fibrillation
The Correct Answer is B
A. Junctional tachycardia: Junctional tachycardia originates from the atrioventricular (AV) node, with a faster rate and usually no visible P waves preceding the QRS complexes.
B. Sinus tachycardia: Sinus tachycardia is characterized by a regular, rapid heart rhythm originating from the sinus node, typically seen after exercise, with identifiable P waves before each QRS complex.
C. Atrial flutter: Atrial flutter presents with a “sawtooth” pattern of P waves, indicating rapid atrial contractions, which is different from sinus tachycardia.
D. Ventricular fibrillation: Ventricular fibrillation is a chaotic and irregular rhythm originating from the ventricles, which is a life-threatening condition.

Correct Answer is A
Explanation
A. Administer oxygen via nasal cannula: The client's symptoms of dyspnea, chest pain, syncope, and hypotension suggest a possible acute cardiovascular event, such as a myocardial infarction (MI) or pulmonary embolism (PE). Administering oxygen should be the priority to improve oxygenation and prevent hypoxia, which could exacerbate the client's symptoms and further compromise cardiac function.
B. Administer prescribed pain medications. Pain relief may be necessary, but stabilizing oxygen levels is the priority.
C. Administer NS IV fluid. Fluid administration may be helpful, but oxygenation is more critical in this situation to address the potential underlying respiratory or cardiac issue.
D. Ask the provider for a dopamine prescription. While dopamine may be used in cases of shock, the immediate action should be to ensure the client is adequately oxygenated.
