What is considered a mild brain injury, unless the injury occurs repeatedly?

Concussion

Brainstem contusion

Subdural hematoma

Epidural hematoma

Answer and Explanation

The Correct Answer is A

A. A concussion is considered a mild traumatic brain injury (TBI) that typically results in a temporary loss of brain function. It is often caused by a blow to the head and may result in confusion, dizziness, and loss of consciousness. However, if concussions occur repeatedly, they can lead to long-term cognitive impairment and other serious conditions like chronic traumatic encephalopathy (CTE).

B. A brainstem contusion is a more severe injury that affects the brainstem, which controls vital functions like breathing and heart rate. It is not classified as a mild injury.

C. A subdural hematoma is a collection of blood between the brain and its outermost covering. It is a serious condition that can result from a traumatic brain injury and is not considered mild.

D. An epidural hematoma is a collection of blood between the skull and the dura mater. It is often caused by a traumatic head injury and is considered a medical emergency, not a mild injury.

Correct Answer is B

Explanation

A. The ECG finding of an irregularly irregular heart rate without P waves is characteristic of atrial fibrillation, which is expected in this client. This finding is not the priority in this situation.

B. Slurred speech is a potential sign of a stroke, which is a serious complication of atrial fibrillation due to the increased risk of thromboembolic events (e.g., stroke). This is the priority finding because it requires immediate intervention to assess and manage a possible stroke.

C. An aPTT of 70 seconds is slightly elevated, but it is within the therapeutic range for heparin therapy (usually 1.5 to 2.5 times the normal value). It does not warrant immediate action.

D. Cloudy and odorous urine could indicate a urinary tract infection or other issue, but it is not immediately life-threatening compared to the potential for a stroke in this client.

A. A sensory warning that a seizure is imminent B. A brief loss of consciousness accompanied by staring C. A continuous seizure state in which seizures occur in rapid succession D. A period of sleepiness following the seizure during which arousal is difficult

Correct Answer is A

Explanation

A. An aura is a sensory warning (such as a strange taste, smell, or visual disturbance) that often precedes a seizure, indicating that a seizure is imminent. It is a common experience for individuals with certain types of seizures, such as focal seizures.

B. A brief loss of consciousness accompanied by staring is indicative of absence seizures, not an aura.

C. A continuous seizure state in which seizures occur in rapid succession is known as status epilepticus, a medical emergency.

D. A period of sleepiness following the seizure is called the postictal state, but this is not related to an aura, which occurs before the seizure.
