Question

A client is evaluated for an acute onset of seizures. Which diagnostic test does the nurse expect to be completed first?

1. Magnetic resonance imaging.
2. Cerebral angiography.
3. Electroencephalogram.
4. Electromyogram.

Answer 1

An Electroencephalogram (EEG) is the first expected diagnostic test when evaluating a client for an acute onset of seizures because it helps identify the affected brain regions.

Step-by-step explanation:

When evaluating a client for an acute onset of seizures, the diagnostic test that nurses expect to be completed first is an Electroencephalogram (EEG). An EEG is a tool used by neurologists to record brain activity by taping electrodes to the scalp. This test helps to determine which regions of the brain are involved in the seizures. The neurological exam is also a critical component in assessing neurological function rapidly, especially in emergency situations. It can provide a quick overview of CNS function, which is crucial for appropriate treatment and recovery. In comparison, other tests like Magnetic resonance imaging (MRI), Cerebral angiography, and Electromyogram (EMG) are not typically the first modalities used in the acute setting of seizures.
