assessment priorities
This is the earliest and most sensitive indicator of neurological change
Level of consciousness because subtle changes in awareness or arousal occur before other neurological deficits become visible
This neurotransmitter is decreased in Parkinson’s disease leading to tremors
Dopamine deficiency causes impaired control of skeletal muscle movement leading to tremors and rigidity
Damage to the frontal lobe area responsible for speech production causes this condition
Expressive aphasia because the patient cannot form or produce understandable speech
After this procedure the patient must remain flat to prevent headache
Lumbar puncture requires lying flat because CSF leakage can cause severe post procedure headache
The priority nursing intervention for any neurological emergency focuses on this system
Airway management because adequate oxygenation is essential to prevent further brain injury
A decreasing level of consciousness is the earliest sign of this life-threatening condition
Increased intracranial pressure because rising pressure compresses brain tissue and first affects consciousness
This neurotransmitter is responsible for inducing sleep and affecting mood
Serotonin regulates sleep cycles mood and sensory perception
Inability to understand spoken or written language is associated with damage to this brain region
Wernicke’s area dysfunction leads to receptive aphasia with impaired comprehension
Clients receiving contrast dye for imaging must be assessed for allergies to these substances
Iodine or seafood allergies because contrast agents can trigger severe allergic reactions
Widening pulse pressure bradycardia and irregular respirations indicate this late finding
Cushing’s triad signals severe increased intracranial pressure and impending brain herniation
This component of consciousness is controlled by the brainstem and assessed by eye opening
Arousal or wakefulness because the brainstem regulates the ability to open eyes to voice or pain stimuli
This neurotransmitter helps maintain arousal and wakefulness from deep sleep
Norepinephrine supports alertness mood regulation and the sleep wake cycle
This condition results in poorly articulated speech due to muscle control issues
Dysarthria occurs because of impaired motor control rather than loss of language ability
Elevated lymphocytes in cerebrospinal fluid indicate this condition
Infection such as viral meningitis or tuberculosis because immune response increases lymphocyte count
A sudden severe headache described as the worst of life indicates this condition
Subarachnoid hemorrhage because rupture of an aneurysm causes rapid bleeding into the subarachnoid space
Asking a client to state person place time and situation assesses this higher-level function
Awareness because it reflects cognitive processing including orientation memory and understanding
This neurotransmitter speeds up nerve impulse transmission and is broken down by cholinesterase
Acetylcholine increases signal transmission between nerves and is inactivated by cholinesterase enzymes
Partial loss of motor function is described by this term
Paresis indicates incomplete paralysis with some preserved movement
Low glucose levels in cerebrospinal fluid are most consistent with this type of infection
Bacterial infection because bacteria consume glucose in the spinal fluid
A Glasgow Coma Scale score below 9 indicates this severity level
Severe traumatic brain injury because the patient often requires airway support and immediate intervention
Headaches that are worse in the morning or wake a patient from sleep are considered this type of finding
Neurological red flag because changes in headache pattern may indicate increased intracranial pressure or brain pathology
Damage to this system affects overall alertness and consciousness
Reticular activating system because it controls awareness and the ability to remain awake and alert
Extension of the arms and legs in response to pain indicates this severe form of brain injury
Decerebrate posturing reflects brainstem damage and is a late sign of severe neurological impairment
Presence of blood in cerebrospinal fluid indicates this serious condition
Hemorrhage because bleeding into the subarachnoid space contaminates the CSF
This doctrine explains that an increase in brain tissue blood or CSF will raise intracranial pressure unless compensated
Monro Kellie doctrine describes the fixed skull volume and the need for compensation between its components
