A nurse is analyzing a client's electrocardiogram (ECG) strip and identifies the following information:

Heart rate: 92/min

Rhythm: Irregular

P wave: Unable to identify

PR interval: Unable to measure

QRS duration: O. 1 0 seconds
Based upon this information, the nurse should interpret the client's rhythm as indicating which of the following?

Atrial fibrillation

Sinus bradycardia

Supraventricular tachycardia

First-degree heart block

Answer and Explanation

The Correct Answer is A

A. Atrial fibrillation: Atrial fibrillation is characterized by an irregularly irregular rhythm, absence of identifiable P waves, and irregular ventricular response. The heart rate in atrial fibrillation can be variable, and the absence of identifiable P waves indicates disorganized atrial electrical activity.

B. Sinus bradycardia: Sinus bradycardia is characterized by a regular rhythm with a heart rate less than 60 beats per minute (bpm) and normal P waves preceding each QRS complex. In sinus bradycardia, the PR interval and QRS duration are typically within normal limits.

C. Supraventricular tachycardia: Supraventricular tachycardia (SVT) is characterized by a regular rhythm with a heart rate greater than 100 bpm. SVT typically presents with narrow QRS complexes and may or may not have discernible P waves.

D. First-degree heart block: First-degree heart block is characterized by a prolonged PR interval (>0.20 seconds) but maintains a regular rhythm with normal QRS duration. In first-degree heart block, P waves are typically identifiable, and the rhythm is not irregular.

Correct Answer is B

Explanation

A. Septal myectomy: Septal myectomy is a surgical procedure primarily used to treat hypertrophic cardiomyopathy (HCM), not atrial fibrillation. It involves removing a portion of the thickened septal wall in the heart to improve blood flow.

B. Synchronized electrical cardioversion: Synchronized electrical cardioversion is a procedure used to convert abnormal heart rhythms, such as atrial fibrillation, back to normal sinus rhythm. It involves delivering a synchronized electrical shock to the heart at a specific point in the cardiac cycle to restore normal rhythm.

C. Pericardiocentesis: Pericardiocentesis is a procedure used to remove fluid from the pericardial sac surrounding the heart. It is typically performed to relieve cardiac tamponade or to investigate the cause of pericardial effusion.

D. Pericardial window: A pericardial window is a surgical procedure performed to create a permanent opening in the pericardium, the sac surrounding the heart. It is usually done to drain fluid or air from the pericardial space, often in cases of recurrent pericardial effusion or cardiac tamponade.

A. Marfan's syndrome B. Hypercarbia C. Falls D. Ventriculostomy

Correct Answer is C

Explanation

A. Marfan's syndrome: Marfan's syndrome is a genetic disorder that affects the connective tissue in the body, predisposing individuals to various cardiovascular, skeletal, and ocular abnormalities. While Marfan's syndrome can present with certain cranial and intracranial manifestations, such as dural ectasia and intracranial aneurysms, it is not typically considered a direct risk factor for traumatic brain injury (TBI).

B. Hypercarbia: Hypercarbia refers to elevated levels of carbon dioxide (CO2) in the blood. While severe hypercarbia can lead to cerebral vasodilation and potentially exacerbate intracranial pressure in individuals with traumatic brain injury, it is not considered a direct risk factor for TBI itself.

C. Falls: Falls are a significant risk factor for traumatic brain injury (TBI), particularly in older adults and young children. Falls can occur due to various factors such as environmental hazards, impaired mobility, balance issues, or neurological conditions. Falls are a leading cause of TBI-related emergency department visits, hospitalizations, and fatalities.

D. Ventriculostomy: Ventriculostomy involves the placement of a catheter into the ventricular system of the brain to monitor intracranial pressure (ICP) or drain cerebrospinal fluid (CSF). While ventriculostomy is a procedure commonly performed in the management of severe traumatic brain injury to monitor and manage intracranial pressure, it is not a risk factor for TBI itself.
