A common medication treatment for Parkinson's disease is levodopa/carbidopa combination medication. The nurse knows that this medication is used because which of the following neurotransmitter is decreased in a person with Parkinson's disease?

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.

A. Vasoconstrictors (Imitrex), such as sumatriptan, are commonly used to treat the headache stage of a migraine by constricting blood vessels, which helps alleviate the pain.

B. A dark, quiet environment is beneficial for migraine sufferers as bright lights and loud noises can exacerbate symptoms. Resting in a calm environment can help reduce discomfort.

C. While teaching relaxation is helpful for migraine prevention, it may not be effective in the acute phase of the headache. Relaxation techniques are more useful in managing triggers and reducing frequency.

D. Exercise is generally not recommended during the headache stage of a migraine, as it can worsen the pain. Light activity may help during the prodromal phase, but not during the headache itself.

E. Analgesics (NSAIDs) such as ibuprofen or naproxen are often used to relieve the pain during the headache stage of a migraine. They can help reduce inflammation and discomfort.

F. Teaching stress reduction is beneficial for preventing migraines but is not typically helpful during the headache stage itself. Stress management is more useful in the long term.
