Module 4 Flashcards
A person is diagnosed with an alteration in arousal. Which clinical manifestation is typical of this diagnosis?
Vomiting without nausea
An APRN knows the onset of an acute confusion state?
Sudden
Seizures are initiated by:
hyperexcitability of neurons
An APRN recalls that increased intracranial pressure can occur because of:
cerebral edema
The APRN has an areflexic patient and understands this means the person has:
no tendon reflexes
An unconscious person is admitted to the hospital after a motorcycle accident. The person experienced a brief loss of consciousness at the scene followed by an awake, lucid period of 1 hour. The APRN suspects this individual has a:
extradural hematoma
An APRN knows that spinal shock results in:
poor venous circulation

arteriosclerotic changes
A person arrives at the clinic and reports a unilateral headache for 2 days that worsens with movement and light. No trauma has occurred. The APRN suspects:
migraine headaches
An APRN recalls that increased intracranial pressure with hydrocephalus may be the result of:
reduced reabsorption of CSF
A child has meningitis. An APRN observes flexion of the knees and hips when the child’s neck is rapidly flexed forward. Which sign did the APRN observe as positive?
Brudzinski sign

Kernig
Pattern of breathing:
apneustic, cluster, and ataxic
Pupillary changes – ischemia/hypoxia

Pupillary changes – opiates
pinpoint pupils
Brain death- body cannot maintain
internal homeostasis
Brain death is irreversible cessation of the
entire brain, including brainstem and cerebellum occurs.
Brain death (EEG characteristics)
isoelectric (flat) electroencephalography (EEG) for 6-12 hours
Brain death
can no longer maintain the body’s internal homeostasis
Alterations in awareness – pathophysiology - direct
direct destruction from direct ischemia and hypoxia
Alterations in awareness – pathophysiology - indirect
indirect destruction as a result of compression
