A nurse is gathering neurological data on a patient with a neurological injury and observes signs indicative of Cushing’s Triad.
The nurse understands that Cushing’s Triad is a nervous system response that could prevent which of the following conditions?
Brainstem ischemia
Tachycardia
Agonal breathing
Chest pain
The Correct Answer is A
Choice A rationale
Cushing’s Triad, which includes bradycardia (low heart rate), irregular respiration, and widened pulse pressure, is a nervous system response that could prevent brainstem ischemia. Brainstem ischemia is a condition where there is insufficient blood flow to the brainstem, which can lead to cell death.
Choice B rationale
While tachycardia (high heart rate) is a serious condition, it is not typically prevented by Cushing’s Triad.
Choice C rationale
Agonal breathing, which is characterized by gasping, labored breathing, particularly when lying flat, is not typically prevented by Cushing’s Triad.
Choice D rationale
Chest pain is not typically prevented by Cushing’s Triad. Cushing’s Triad is a response to increased intracranial pressure, not a cardiac condition.

Correct Answer is A
Explanation
Choice A rationale
Nausea and vomiting are common symptoms associated with migraines. Asking about these symptoms can help confirm a diagnosis of a migraine.
Choice B rationale
Sensitivity to light, also known as photophobia, is a common symptom of migraines. However, the question “Are the lights in here bothering you?” is less specific to migraines as it could be indicative of several other conditions as well.
Choice C rationale
While confusion or clouded thinking can occur with migraines, it is not as common as other symptoms such as nausea, vomiting, and sensitivity to light.
Choice D rationale
Unusual smells, known as olfactory hallucinations, are not typically associated with migraines. They are more commonly associated with conditions such as epilepsy.
Choice E rationale
Weakness before the headache started or currently feeling weak now is not a typical symptom of migraines. It could be indicative of a more serious condition, such as a stroke.
Correct Answer is ["A","D","E","F"]
Explanation
Choice A rationale: The nurse should prepare to administer tissue plasminogen activator (tPA). This medication is used to dissolve blood clots that have formed in the blood vessels of the brain. The client’s CT scan shows a large area of decreased attenuation in the left hemisphere, which is indicative of a stroke. The administration of tPA is time-sensitive and should be initiated as soon as possible after the onset of symptoms if there is no evidence of hemorrhage on the CT scan.
Choice B rationale: Positioning the client on his right side is not necessarily beneficial in this situation. The client is experiencing symptoms of a stroke, and positioning will not alleviate these symptoms. It is more important to focus on interventions that can potentially reverse the effects of the stroke, such as the administration of tPA.
Choice C rationale: There is no indication that the client requires a bolus of 50% dextrose. The client’s blood glucose levels are within normal limits, and hypoglycemia is not a concern at this time. Administering a bolus of 50% dextrose without indication could potentially lead to hyperglycemia.
Choice D rationale: The nurse should anticipate the need for endotracheal intubation. The client’s condition is deteriorating, and he is now unresponsive to verbal stimuli and only responds to painful stimuli. This indicates a decreased level of consciousness, which can compromise the client’s airway. Endotracheal intubation may be necessary to protect the client’s airway and ensure adequate ventilation.
Choice E rationale: The nurse should prepare to administer antihypertensive medication. The client’s blood pressure is significantly elevated, which can further exacerbate the damage caused by a stroke. Antihypertensive medication can help to lower the client’s blood pressure and reduce the risk of further complications.
Choice F rationale: The nurse should use a calm and reassuring approach when interacting with the client. This can help to reduce anxiety and promote a sense of safety. It is important to remember that the client may be scared and confused due to his symptoms, and a calm and reassuring approach can help to alleviate these feelings.
Choice G rationale: Restricting all fluids and sodium intake is not indicated in this situation. While fluid and sodium balance is important in stroke patients, there is no indication that the client is fluid overloaded or has a condition that would require sodium restriction. Furthermore, the client has been prescribed IV fluids, indicating that fluid restriction is not appropriate at this time.
