The nurse is teaching a class to a group of staff nurses about traumatic brain injury which condition would the nurse identify as having the highest risk of a fatal outcome within the first 24 hours post-injury?

Subdural hematoma

Diffuse axonal injury

Intracranial hemorrhage

Epidural hematoma

Answer and Explanation

The Correct Answer is D

A. Subdural hematoma: Subdural hematomas develop more slowly and typically present a higher risk for delayed deterioration, but not usually within the first 24 hours.

B. Diffuse axonal injury: While severe, diffuse axonal injury typically causes a prolonged coma rather than immediate fatality within 24 hours.

C. Intracranial hemorrhage: This is severe but often depends on the size and location of the bleed.

D. Epidural hematoma: Epidural hematomas are associated with arterial bleeding and rapid deterioration due to increased intracranial pressure, making them the most fatal within 24 hours.

Correct Answer is B

Explanation

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.

A. Atrial tachycardia B. Ventricular fibrillation C. Atrial flutter D. Sinus bradycardia

Correct Answer is C

Explanation

A. Atrial tachycardia: Atrial tachycardia is a rapid heart rhythm originating from the atria, but it does not have the characteristic "sawtooth" pattern seen in atrial flutter.

B. Ventricular fibrillation: Ventricular fibrillation is a chaotic rhythm originating from the ventricles, characterized by irregular, rapid waves with no discernible P waves or QRS complexes.

C. Atrial flutter: Atrial flutter is recognized by a "sawtooth" pattern of P waves, indicating rapid atrial depolarizations.

D. Sinus bradycardia: Sinus bradycardia is a slow but regular rhythm originating from the sinus node, with normal P waves and QRS complexes.
