Symptoms of a sensory seizure include

hallucinations, flashing lights, tingling sensations, vertigo, déjà vu, and smelling a foul odor.

Absence seizures occur most commonly

in children. They usually begin with a brief change in the level of consciousness, signaled by blinking or rolling of the eyes, a blank stare, and slight mouth movements.

A Jacksonian seizure

begins as a localized motor seizure. The client experiences a stiffening or jerking in one extremity, accompanied by a tingling sensation in the same area.

A nurse is working on a neurological unit with a nursing student who asks the difference between primary and secondary headaches. The nurse's correct response will include which of the following statements?

"A secondary headache is associated with an organic cause, such as a brain tumor." p2004 Explanation: A secondary headache is a symptom associated with an organic cause, such as a brain tumor or an aneurysm. A primary headache is one for which no organic cause can be identified. These types include migraine, tension, and cluster headaches. Secondary headaches can be located in all areas of the head.

A client with newly diagnosed seizures asks about stigma associated with epilepsy. The nurse will respond with which of the following statements?

"Many people with developmental disabilities resulting from neurologic damage also have epilepsy."

A client is exhibiting signs of increasing intracranial pressure (ICP). Which intravenous solution (IV) would the nurse anticipate hanging?

mannitol

A client undergoes a scheduled electroencephalogram (EEG). Which of the following post-procedure activities should the nurse carry out for the client?

Allow the client to rest and shampoo the client's hair. p1968 Explanation: After an EEG, the nurse should ensure rest for the sleep-deprived client and shampoo the client's hair to remove the glue used to affix electrodes to the scalp. The client is advised not to take sedative drugs and caffeine-related drinks before the EEG, and there is no reason to provide the client with them after the test. The nurse should not measure the LOC, the heart rate, or the pulse rate of the client unless advised by the physician.

The school nurse notes a 6-year-old running across the playground with his friends. The child stops in midstride, freezing for a few seconds. Then the child resumes his progress across the playground. The school nurse suspects what in this child?

An absence seizure Explanation: Absence seizures, formerly referred to as petit mal seizures, are more common in children. They are characterized by a brief loss of consciousness during which physical activity ceases. The person stares blankly; the eyelids flutter; the lips move; and slight movement of the head, arms, and legs occurs. These seizures typically last for a few seconds, and the person seldom falls to the ground. Because of their brief duration and relative lack of prominent movements, these seizures often go unnoticed. People with absence seizures can have them many times a day. Partial, or focal, seizures begin in a specific area of the cerebral cortex. Both myoclonic and tonic-clonic seizures involve jerking movements.

A client is scheduled for an EEG. The client inquires about any diet-related prerequisites before the EEG. Which diet-related advice should the nurse provide to the client?

Avoid taking sedative drugs or drinks that contain caffeine for at least 8 hours before the test p1969 Explanation: The client is advised to refrain from taking sedative drugs or consuming food or drinks that contain caffeine for at least 8 hours before the test, because these may interfere with the EEG result. The client is not advised to increase or decrease the intake of minerals in the diet.

Which term refers to a method of recording, in graphic form, the electrical activity of a muscle?

Electromyography Explanation: An electromyogram is obtained by inserting needle electrodes into the skeletal muscles to measure changes in the electrical potential of the muscles. Electroencephalography is a method of recording, in graphic form, the electrical activity of the brain. Electrocardiography is performed to assess the electrical activity of the heart. Electrogastrography is an electrophysiologic study performed to assess gastric motility disturbances. p1969

A client has undergone a lumbar puncture as part of a neurological assessment. The client is put under the care of a nurse after the procedure. Which important postprocedure nursing intervention should be performed to ensure the client's maximum comfort?

Encourage the client to drink liberal amounts of fluids p1970 Explanation: The nurse should encourage the client to take liberal fluids and should inspect the injection site for swelling or hematoma. These measures help restore the volume of cerebrospinal fluid extracted. The client is administered antihistamines before a test only if he or she is allergic to contrast dye and contrast dye will be used. The room of the client who has undergone a lumbar puncture should be kept dark and quiet. The client should be encouraged to rest, because sensory stimulation tends to magnify discomfort.

A nurse is caring for a client with deteriorating neurologic status. The nurse is performing an assessment at the beginning of the shift that reveals a falling blood pressure and heart rate, and the client makes no motor response to stimuli. Which documentation of neuromuscular status is most appropriate?

Flaccidity

The nurse is caring for a patient with an altered LOC. What is the first priority of treatment for this patient?

Maintenance of a patent airway p1975 Explanation: The first priority of treatment for the patient with altered LOC is to obtain and maintain a patent airway.

When educating a patient about the use of antiseizure medication, what should the nurse inform the patient is a result of long-term use of the medication in women?

Osteoporosis

A patient is admitted to the hospital for management of an extrapyramidal disorder. Included in the physician's admitting orders are the medications levodopa, benztropine, and selegiline. The nurse knows that most likely, the client has a diagnosis of:

Parkinson's disease. Explanation: Although antiparkinson drugs are used in some clients with Huntington's disease, these drugs are most commonly used in the medical management of Parkinson's disease. The listed medications are not used to treat a seizure disorder. The listed medications are not used to treat MS.

A client is actively hallucinating during an assessment. The nurse would be correct in documenting the hallucination as a disturbance in

Thought content

A client is scheduled for standard EEG testing to evaluate a possible seizure disorder. Which nursing intervention should the nurse perform before the procedure?

Withhold anticonvulsant medications for 24 to 48 hours before the exam p1968 Explanation: Anticonvulsant agents, tranquilizers, stimulants, and depressants should be withheld 24 to 48 hours before an EEG because these medications can alter EEG wave patterns or mask the abnormal wave patterns of seizure disorders. To increase the chances of recording seizure activity, it is sometimes recommended that the client be deprived of sleep on the night before the EEG. Coffee, tea, chocolate, and cola drinks are omitted in the meal before the test because of their stimulating effect. However, meals are not omitted, because an altered blood glucose concentration can cause changes in brain wave patterns. The client is informed that a standard EEG takes 45 to 60 minutes; a sleep EEG requires 12 hours.

A client is sitting in a chair and begins having a tonic-clonic seizure. The most appropriate nursing response is to:

carefully move the client to a flat surface and turn him on his side. Explanation: When caring for a client experiencing a tonic-clonic seizure, the nurse should help the client to a flat nonelevated surface and then position him on his side to ensure that he doesn't aspirate and to protect him from injury. These steps help reduce the risk of injury from falling or hitting surrounding objects and help establish an open airway. The client shouldn't be restrained during the seizure. Also, nothing should be placed in his mouth; anything in the mouth could impair ventilation and damage the inside of the mouth.

A nurse is caring for a client with a diagnosis of trigeminal neuralgia. Which activity is altered as a result of this diagnosis?

chewing

The nurse is assisting the physician in completing a lumbar puncture. Which would the nurse note as a concern?

Cerebrospinal fluid is cloudy in nature. p1969 Explanation: The nurse would note cloudy cerebrospinal fluid as a concern. Cloudy fluid is an indication of infection. The physician is correct to maintain aseptic procedure. A piercing feeling and pressure relief are common during and after the procedure.

The causes of acquired seizures include what? (Mark all that apply.)

Cerebrovascular disease Metabolic and toxic conditions Brain tumor Drug and alcohol withdrawal Explanation: The specific causes of seizures are varied and can be categorized as idiopathic (genetic, developmental defects) and acquired. Causes of acquired seizures include cerebrovascular disease; hypoxemia of any cause, including vascular insufficiency; fever (childhood); head injury; hypertension; central nervous system infections; metabolic and toxic conditions (eg, renal failure, hyponatremia, hypocalcemia, hypoglycemia, pesticide exposure); brain tumor; drug and alcohol withdrawal; and allergies. p. 1996.

A client experiences loss of consciousness, tongue biting, and incontinence, along with tonic and clonic phases of seizure activity. The nurse should document this episode as which type of seizure?

Generalized Explanation: A generalized seizure causes generalized electrical abnormality in the brain. The client typically falls to the ground, losing consciousness. The body stiffens (tonic phase) and then alternates between episodes of muscle spasm and relaxation (clonic phase). Tongue biting, incontinence, labored breathing, apnea, and cyanosis may also occur. A Jacksonian seizure begins as a localized motor seizure. The client experiences a stiffening or jerking in one extremity, accompanied by a tingling sensation in the same area. Absence seizures occur most commonly in children. They usually begin with a brief change in the level of consciousness, signaled by blinking or rolling of the eyes, a blank stare, and slight mouth movements. Symptoms of a sensory seizure include hallucinations, flashing lights, tingling sensations, vertigo, déjà vu, and smelling a foul odor.
