NURS 351 Neurologic Pre-Class Quiz

A client has just begun to experience an ischemic stroke. The blood supply from the middle cerebral artery is being blocked by a large blood clot. How long before brain cells begin to die due to lack of ATP?

4 to 6 minutes

A nurse educator is explaining basic neuroanatomy to a class of prospective nursing students. Which statement best conveys an aspect of the role of cerebrospinal fluid (CSF)?

CSF cushions the brain and provides a near-water medium for diffusion of nutrients.

Which intracranial volume is most capable of compensating for increasing intracranial pressure?

Cerebrospinal fluid

Select the conditions that would place a client at risk for the development of hypoxia. Select all that apply.

Decreased cardiac output, carbon monoxide poisoning, severe anemia

The nurse is caring for a client with a brain tumor when the client begins to vomit. Which intervention should the nurse do first?

Assess for other signs/symptoms of increased intracranial pressure.

Which components of the nervous system make up the central nervous system?

Brain and spinal cord

When trying to explain the difference between vasogenic versus cytotoxic cerebral edema, the physiology instructor mentions that cytotoxic edema displays which functions in the brain? Select all that apply.

Causes ischemia to build up lactic acid due to anaerobic metabolism, allows cells to increase volume to the point of rupture, damaging neighboring cells

Select the function of the occipital lobe.

Color, motion, and depth perception

Nutrition students are studying the nervous system, which has a high rate of metabolism. What is its major fuel source?

Glucose

Which physiologic principle can cause hydrocephalus? Select all that apply.

Obstruction of cerebrospinal fluid, decreased absorption of cerebrospinal fluid

The nursing assistant reports to the registered nurse that a client with a brain tumor has a blood pressure of 180/100 mm Hg and a pulse of 50 bpm. Which action is the correct nursing intervention?

Report to physician the client's signs of increased intracranial pressure.

The nurse is aware that the primary function of the sympathetic nervous system is:

maintenance of vital functions and responding when there is a critical threat to the integrity of the individual.

A client's emergency magnetic resonance imaging (MRI) has been examined by the physician and tissue plasminogen activator (tPA) has been administered to the client. What was this client's most likely diagnosis?

Ischemic stroke

The nurse taking a report on a client coming into the emergency room plans care for a client with brain dysfunction based on which symptom?

Stupor

An adult client has been admitted to a rehabilitation center after hospital treatment for an ischemic stroke. Which aspect of the client's history would be considered to have contributed to his stroke?

The client's blood pressure has historically been in the range of 150/90 to 160/100 mm Hg.

Global or diffuse brain injury is manifested by changes in the level of consciousness.

True

A 20-year-old with no previous medical history developed an episode of palpitations, shortness of breath, and syncope and felt like the situation was not real while awaiting a turn to present a project in class. The client was brought to the emergency department via ambulance approximately one hour after the onset of the episode, and at the time of arrival the symptoms had subsided. The intake nurse noted that the admission electrocardiogram, chest x-ray, and blood work were all with in normal limits. The nurse suspects that the client is suffering from:

a panic attack

A client has developed global ischemia of the brain. The nurse determines this is:

inadequate to meet the metabolic needs of the entire brain.

The nurse is aware that some drugs may be prevented from entering the brain as a function of:

the blood-brain barrier.

The most common cause of ischemic stroke is:

thrombosis
