Protect the client from injury.

A client with neurologic infection develops cerebral edema from syndrome of inappropriate antidiuretic hormone (SIADH). Which is an important nursing action for this client?

Restricting fluid intake and hydration

A client diagnosed with Huntington disease is on a disease-modifying drug regimen and has a urinary catheter in place. Which potential complication is the highest priority for the nurse while monitoring the client?

Urinary tract infection

When the nurse observes that the client has extension and external rotation of the arms and wrists and plantar flexion of the feet, the nurse records the client's posture as

decerebrate.

An osmotic diuretic such as mannitol is given to the client with increased intracranial pressure (ICP) to

dehydrate the brain and reduce cerebral edema.

A nurse is monitoring a client for increasing intracranial pressure (ICP). Early signs of increased ICP include:

diminished responsiveness.

In planning care for a patient with an extrapyramidal disorder, the nurse recognizes that a major difference between Parkinson's disease and Huntington's disease is the development of ________ in clients with advanced Huntington's disease.

hallucinations and delusions

To meet the sensory needs of a client with viral meningitis, the nurse should:

minimize exposure to bright lights and noise.

A client is treated for increased intracranial pressure (ICP). It is important for the client to avoid hypothermia because

shivering in hypothermia can increase ICP.

The nurse is caring for a client immediately after supratentorial intracranial surgery. The nurse performs the appropriate action by placing the patient in the

supine position with the head slightly elevated.

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 nurse is caring for a client with a brain tumor and increased intracranial pressure (ICP). Which intervention should the nurse include in the care plan to reduce ICP?

Administer stool softeners.

Which positions is used to help reduce intracranial pressure (ICP)?

Avoiding flexion of the neck with use of a cervical collar

An older client complains of a constant headache. A physical examination shows papilledema. What may the symptoms indicate in this client?

Brain tumor

Which is the earliest sign of increasing intracranial pressure?

Change in level of consciousness

The nurse is caring for a patient postoperatively after intracranial surgery for the treatment of a subdural hematoma. The nurse observes an increase in the patient's blood pressure from the baseline and a decrease in the heart rate from 86 to 54. The patient has crackles in the bases of the lungs. What does the nurse suspect is occurring?

Increased ICP

A client is receiving hypothermic treatment for uncontrolled fever related to increased intracranial pressure (ICP). Which assessment finding requires immediate intervention?

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

chewing

A client with a spinal cord injury and subsequent urine retention receives intermittent catheterization every 4 hours. The average catheterized urine volume has been 550 ml. The nurse should plan to:

increase the frequency of the catheterizations.

A nurse is assessing a client who has been in a motor vehicle collision. The client directly and accurately answers questions. The nurse notes a contusion to the client's forehead; the client reports a headache. Assessing the client's pupils, what reaction would confirm increasing intracranial pressure?

unequal response

A nurse assesses the patient's level of consciousness using the Glasgow Coma Scale. What score indicates severe impairment of neurologic function?

3

A client is receiving intravenous (IV) mannitol to prevent increased intracranial pressure. The order is for mannitol 1.5 grams per kg of body weight IV now. The client weighs 143 lbs (65 kg). How many grams will the nurse administer to the client? Enter the correct number in tenths.

97.5

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