- A. Is the lesser auricular nerve
- B. Involves the dermatome of C3
- C. Includes the zygomaticotemporal branch of the trigeminal nerve
- D. Includes the vagus
Correct Answer: D

One of the most common features of neurological disorders are Language deficits and are collectively known as
- A. Dysphasias
- B. Alogias
- C. Anomias
- D. Aphasias
Correct Answer: D
Rationale: Aphasia is a language disorder resulting from damage to the brain's language centers, typically in the left hemisphere. It affects the ability to produce or comprehend speech, read, or write. Aphasia can manifest in various forms, such as Broca's aphasia (difficulty speaking) or Wernicke's aphasia (difficulty understanding language). These deficits are common in neurological disorders like stroke, traumatic brain injury, or neurodegenerative diseases.
KL is a 34-year-old male admitted to the hospital (large trauma center) after suffering a traumatic brain injury (TBI) secondary to a serious motor vehicle accident. He was in excellent health prior to the accident. HT: 6'2" WT: 190 pounds (86 kg) What level of energy intake per day is the most appropriate for KL?
- A. 1,800 kcal
- B. 2,100 kcal
- C. 2,400 kcal
- D. 2,700 kcal
Correct Answer: C
Rationale: For a patient with traumatic brain injury (TBI), an energy intake of approximately 2,400 kcal/day is often appropriate to meet increased metabolic demands while avoiding overfeeding, which can exacerbate complications like hyperglycemia or respiratory issues.
Dopamine is an important neurotransmitter. Which disease or disorder results when the neurons in the brain that produce dopamine die?
- A. Multiple sclerosis
- B. Lou Gehrig disease (amyotrophic lateral sclerosis)
- C. Parkinson disease
- D. Seizure disorder
Correct Answer: C
Rationale: Parkinson disease is caused by the degeneration of dopamine-producing neurons in the brain, leading to motor symptoms such as tremors and rigidity. Multiple sclerosis and ALS involve different neurological mechanisms, while seizure disorders are related to abnormal electrical activity in the brain. Dopamine's role in motor control is critical to understanding Parkinson disease.
