The nurse is caring for a patient recovering from an ischemic stroke.
What intervention best addresses a potential complication after an ischemic stroke?

Choice C rationale
When providing care for a comatose patient, a nurse should evaluate motor responses by observing the patient’s response to painful stimuli. This can be done by applying a painful stimulus, such as a trapezius pinch or nailbed pressure, and observing the patient’s motor response. Purposeful or semi-purposeful movements, such as localizing or withdrawing from pain, can provide valuable information about the patient’s level of consciousness and neurological function.
Choice A rationale
The Romberg test is used to evaluate balance and is not typically used to evaluate motor responses in a comatose patient.
Choice B rationale
Assessing the patient’s sensitivity to temperature and touch can provide information about sensory function, but it does not directly evaluate motor responses.
Choice D rationale

Observing the reaction of pupils to light can provide information about cranial nerve function, but it does not directly evaluate motor responses.

Choice A rationale
Status epilepticus is a medical emergency characterized by continuous or rapid-fire seizures. Intravenous diazepam is one of the first-line treatments for this condition. It works by enhancing the effect of gamma-aminobutyric acid (GABA), a neurotransmitter that inhibits brain activity, thereby helping to stop the seizure.
Choice B rationale
Oral lorazepam is not typically used to halt a seizure immediately due to its slower onset of action compared to intravenous administration.
Choice C rationale
Oral phenytoin is not typically used to halt a seizure immediately. It is more commonly used for the long-term management of seizures.
Choice D rationale
Intravenous phenobarbital is a second-line treatment for status epilepticus, used when first- line treatments such as diazepam are ineffective.
