A traumatic brain injury on the brainstem can cause which of the following?

Emotional lability

Personality changes

Diabetes insipidus

Unstable vital signs

Answer and Explanation

The Correct Answer is D

A. Emotional lability (rapid mood swings) can occur with brain injuries, but it is more commonly associated with damage to the frontal lobe, not the brainstem.

B. Personality changes are also more likely to result from damage to the frontal lobe or other areas of the brain responsible for behavior and personality, not the brainstem.

C. Diabetes insipidus can result from brain injury, particularly damage to the hypothalamus or pituitary gland, but it is not a direct consequence of brainstem injury.

D. Unstable vital signs are a common result of damage to the brainstem, which is responsible for regulating autonomic functions such as heart rate, blood pressure, and respiration. Damage to the brainstem can lead to life-threatening instability in these vital functions.

Correct Answer is D

Explanation

A. Dysphasia is a general term for difficulty with speech and language, which can involve problems with speaking, understanding, reading, or writing. It is not specific to the patient's response of raising an arm instead of sticking out the tongue.

B. Dysarthria refers to difficulty with the physical act of speaking due to weakness or incoordination of the muscles involved in speech. It does not involve comprehension or understanding of language.

C. Expressive aphasia refers to difficulty expressing thoughts verbally or in writing, but the patient typically understands language. This does not match the patient's response to the nurse's command.

D. Receptive aphasia is characterized by difficulty understanding spoken or written language. The patient may not comprehend the nurse's instructions, leading to inappropriate responses, such as raising an arm instead of sticking out the tongue.

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.
