Final answer:
A nurse should expect impulsive behavior as the most likely neurologic deficit in a patient who has experienced a right hemispheric stroke. This is due to the right brain hemisphere's role in judgment, self-control, and spatial awareness.
Step-by-step explanation:
When assessing a client who has experienced a right hemispheric stroke, the nurse should be aware of the common neurological deficits associated with this condition. Unlike strokes occurring in the left hemisphere of the brain, which can cause aphasia, right hemispheric strokes often lead to different kinds of impairments. A right-sided stroke typically does not result in traditional aphasia but can affect the use of language in terms of understanding figurative speech, nonverbal aspects, and emotional expression. Moreover, it is well-documented that a right hemispheric stroke can lead to difficulties with spatial awareness and attention to the left side, known as right-sided neglect. In addition, behavioral changes can manifest as impulsive behavior, which may include acting without consideration for social norms or the consequences of actions.
Therefore, the most likely neurologic deficit a nurse should expect is "c. Impulsive behavior" due to damage in the brain's right hemisphere affecting judgment, self-control, and spatial awareness. However, assessing individual symptoms and deficits is crucial for each patient, as stroke effects can vary greatly depending on the exact location and extent of the brain injury.
