Decreased peristalsis

A client with a suspected brain tumor is scheduled for a computed tomography (CT) scan. What should the nurse do when preparing the client for this test?

Dilated pupils

Which lobe of the brain is responsible for concentration and abstract thought?

Frontal

Which lobe of the brain is responsible for concentration and abstract thought?

Hypothalamus

Which of the following areas of the brain are responsible for temperature regulation?

Hypothalamus

What is the function of cerebrospinal fluid (CSF)?

A nurse is assisting during a lumbar puncture. How should the nurse position the client for this procedure?

Lateral recumbent, with chin resting on flexed knees

Which of the following is an age-related change in the nervous system?

A client is diagnosed with a brain tumor. The nurse's assessment reveals that the client has difficulty interpreting visual stimuli. Based on these findings, the nurse suspects injury to which lobe of the brain?

Occipital

Which of the following cranial nerves is responsible for muscles that move the eye and lid?

Oculomotor

Which lobe of the brain is responsible for spatial relationships?

Parietal

A client who has sustained a head injury to the parietal lobe cannot identify a familiar object by touch. The nurse knows that this deficit is which of the following?

Tactile agnosia

Which of the following cerebral lobes contains the auditory receptive areas?

Temporal

The nurse is performing a neurological assessment of a client who has sustained damage to the frontal cortex. Which of the following deficits will the nurse look for during assessment?

The inability to tell how a mouse and a cat are alike. The client with damage to the fronal cortex will display a deficit in intellectual functioning. Questions designed to assess this capacity might include the ability to recognize similarities: for example, how are a mouse and dog or pen and pencil alike?

A patient is actively hallucinating during an assessment. The nurse would be correct in documenting the hallucination as a disturbance in which of the following?

Thought content Explanation: Hallucinations are a disturbance of thought content. They are not disturbances in motor ability, intellectual function, or emotional status.

The spinal cord is composed of 31 pairs of spinal nerves. How many pairs of thoracic nerves are contained within the spinal column?

A client experienced a stroke that damaged the hypothalamus. The nurse should anticipate that the client will have problems with:

body temperature control.

Nurse observes pt has extentin and external rotation of hte arms and wrist and extention, plantar flexion and internal rotation of the feet.

decerebrate :

After a plane crash, a client is brought to the emergency department with severe burns and respiratory difficulty. The nurse helps to secure a patent airway and attends to the client's immediate needs, then prepares to perform an initial neurologic assessment. The nurse should perform an:

evaluation of the corneal reflex response.

A client is admitted to an acute care facility with a suspected dysfunction of the lower brain stem. The nurse should monitor this client closely for:

hypoxia. Explanation: Lower brain stem dysfunction alters bulbar functions, such as breathing, talking, swallowing, and coughing. Therefore, the nurse should monitor the client closely for hypoxia. Temperature control, vision, and gait aren't lower brain stem functions.

health promotion efforts to decrease the risk for ischemis stroke involve encouraging a healthy lifestyle

low fat low cholesterol and increasing exercise

Romberg test Explanation: In the Romberg test, the client stands with feet close together and eyes closed.

Which neurotransmitter demonstrates inhibitory action, helps control mood and sleep, and inhibits pain pathways?

Serotonin

term refers to muscular hypertonicity adn increased resistance to stretch

spasticity

During a routine physical examination to assess a client's deep tendon reflexes, a nurse should make sure to:

support the joint where the tendon is being tested.

"The blood will seal the hole in the dura and prevent further loss of cerebral spinal fluid."
