The earliest sign of serious impairment of brain circulation related to increased ICP is:

A change in consciousness The earliest sign of increasing ICP is a change in the LOC. Any changes in LOC should be reported immediately.

A nurse is reviewing the trend of a client's scores on the Glasgow Coma Scale (GCS). This provides what potential information to the nurse about the client's status?

An assessment of the client's current level of consciousness The Glasgow Coma Scale (GCS) examines three responses related to level of consciousness (LOC): eye opening, best verbal response, and best motor response. It is particularly useful for monitoring changes during the acute phase, the first few days after a head injury. It does not take the place of an in-depth neurologic assessment and does not provide knowledge about proceeding events.

The nurse is caring for a client who had a hemorrhagic stroke. What assessment finding constitutes an early sign of deterioration?

Alteration in level of consciousness (LOC) Alteration in LOC is the earliest sign of deterioration in a client after a hemorrhagic stroke, such as mild drowsiness, slight slurring of speech, and sluggish papillary reaction. Sudden headache may occur, but generalized pain is less common. Seizures and shortness of breath are not identified as early signs of hemorrhagic stroke.

A client was running along an ocean pier, tripped on an elevated area of the decking, and struck his head on the pier railing. According to his friends, "He was unconscious briefly and then became alert and behaved as though nothing had happened." Shortly afterward, he began complaining of a headache and asked to be taken to the emergency department. If the client's intracranial pressure (ICP) is increasing, the nurse should expect to observe which sign first?

Declining level of consciousness (LOC) With a brain injury such as an epidural hematoma (a likely diagnosis, based on this client's symptoms), the initial sign of increasing ICP is a change in LOC. As neurologic deterioration progresses, manifestations involving pupillary symmetry, breathing patterns, and posturing will occur.

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

Dehydrate the brain and reduce cerebral edema Osmotic diuretics draw water across intact membranes, thereby reducing the volume of brain and extracellular fluid. Antipyretics and a cooling blanket are used to control fever in the client with increased ICP. Chlorpromazine may be prescribed to control shivering in the client with increased ICP. Medications such as barbiturates are given to the client with increased ICP to reduce cellular metabolic demands.

The nurse is caring for a patient with increased ICP. As the pressure rises, what osmotic diuretic does the nurse prepare to administer?

Mannitol If signs and symptoms of increased ICP occur, efforts to decrease the ICP are initiated: alignment of the head in a neutral position without flexion to promote venous drainage, elevation of the head of the bed to 30 degrees (when prescribed), administration of mannitol (an osmotic diuretic), and possible administration of pharmacologic paralyzing agents.

A nurse conducts the Romberg test on a client by asking the client to stand with the feet close together and the eyes closed. As a result of this posture, the client suddenly sways to one side and is about to fall when the nurse intervenes and saves the client from being injured. How should the nurse interpret the client's result?

Positive Romberg Test, indicating a problem with equilibrium If the client sways and starts to fall during the Romberg test, it indicates a positive result. This means the client has a problem with equilibrium. The examiner or the nurse stands fairly close to the client during the test to prevent the client from falling. The Romberg test is used to assess the client's motor function, including muscle movement, size, tone, strength, and coordination. However, the Romberg test is not used to assess the client's level of consciousness, body mass, or vision.

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 should avoid hypothermia in a client with increased ICP because hypothermia causes shivering. Shivering, in turn, can increase intracranial pressure. Hypothermia in a client with ICP does not indicate malaria or meningitis and is not likely to cause death.

Which oncologic emergency involves the failure in the negative feedback mechanism that normally regulates the release of antidiuretic hormone (ADH)?

Syndrome of inappropriate antidiuretic hormone release (SIADH) SIADH is a result of the failure in the negative feedback mechanism that normally regulates the release of antidiuretic hormone (ADH). Cardiac tamponade is an accumulation of fluid in the pericardial space. DIC is a complex disorder of coagulation and fibrinolysis, which results in thrombosis and bleeding. Tumor lysis syndrome is a rapidly developing oncologic emergency that results from the rapid release of intracellular contents as a result of radiation- or chemotherapy-induced cell destruction of large or rapidly growing cancers such as leukemia.

A nurse is performing a neurologic assessment on a client with a stroke and cannot elicit a gag reflex. This deficit is related to cranial nerve (CN) X, the vagus nerve. What will the nurse consider a priority nursing diagnosis?

Risk for aspiration CN X, the vagus nerve, involves the gag reflex, laryngeal hoarseness, swallowing ability, and symmetrical rise of the uvula and soft palate. An impaired gag reflex indicates a danger for aspiration and subsequent pneumonia. An impaired vagus nerve will not affect balance, skin integrity, or intracranial adaptive capacity.
