The nurse is conducting an assessment on a patient suspected of having a stroke. Which assessment finding is most indicative of a stroke?

Choice A rationale

Facial droop is a classic symptom of stroke. It occurs when there’s weakness or paralysis on one side of the face, which is caused by a disruption in the nerve signals due to a stroke. This can be easily observed in the person’s smile, as it will appear uneven.
Choice B rationale
While dysrhythmias can be associated with stroke, they are not the most indicative symptom. Dysrhythmias are more commonly associated with heart conditions.
Choice C rationale
Periorbital edema, or swelling around the eyes, is not typically a symptom of stroke. It can be caused by various conditions such as allergies, infections, or kidney problems.
Choice D rationale
Projectile vomiting is not typically a symptom of stroke. It can be caused by various conditions such as gastrointestinal issues, brain tumors, or increased intracranial pressure.

Choice A rationale
Myasthenia gravis is a neuromuscular disorder characterized by weakness and fatigue of voluntary muscles. Edrophonium is a medication that is used in the diagnosis and treatment of myasthenia gravis. It works by inhibiting the breakdown of acetylcholine, a neurotransmitter that transmits signals in the nervous system, thereby improving muscle strength.
Choice B rationale
Myasthenia gravis is not a disorder of motor and sensory dysfunction. It primarily affects the neuromuscular junction, leading to muscle weakness and fatigue. Sensory function is typically not affected in myasthenia gravis.
Choice C rationale
This statement is correct in that myasthenia gravis does not cause sensory impairment. However, it does not indicate an understanding of the disease as a whole, as it does not address the primary symptom of muscle weakness.
Choice D rationale
Myasthenia gravis does cause progressive muscle weakness, but it does not cause sensory deficits. Therefore, this statement indicates a partial understanding of the disease.
