Which three symptoms are characteristic of Cushing triad associated with increased ICP?
Bradycardia, hypertension, and widening pulse pressure
Widening pulse pressure, headache, and seizure
Hypertension, tachycardia, and headache
Hypotension, tachycardia, and narrowing pulse pressure
The Correct Answer is A
A. Bradycardia, hypertension, and widening pulse pressure
This combination of symptoms is characteristic of Cushing's triad. Bradycardia (slow heart rate), hypertension (elevated blood pressure), and widening pulse pressure (difference between systolic and diastolic blood pressure) are indicative of increased ICP, specifically resulting in the compression of brain structures that regulate vital functions.
B. Widening pulse pressure, headache, and seizure
While headache and seizure may occur in patients with increased ICP, widening pulse pressure alone is not sufficient to meet the criteria of Cushing's triad. The presence of bradycardia and hypertension, along with widening pulse pressure, is more indicative of Cushing's triad.
C. Hypertension, tachycardia, and headache
Hypertension and headache may occur in patients with increased ICP, but the absence of bradycardia and widening pulse pressure makes this option less characteristic of Cushing's triad.
D. Hypotension, tachycardia, and narrowing pulse pressure
Hypotension (low blood pressure) and narrowing pulse pressure are not typically associated with Cushing's triad. Tachycardia (rapid heart rate) may occur in response to increased ICP, but it is usually accompanied by bradycardia rather than hypotension.

Correct Answer is D
Explanation
A. Polyuria:
Polyuria, or increased urine output, is not typically associated with increased intracranial pressure. It may occur due to other factors such as diabetes insipidus or fluid administration.
B. Battle's sign:
Battle's sign refers to bruising behind the ear and is often associated with basilar skull fractures. While it can indicate a head injury, it is not a direct manifestation of increased intracranial pressure.
C. Nuchal rigidity:
Nuchal rigidity, stiffness of the neck muscles, is commonly associated with meningitis rather than increased intracranial pressure. It is a sign of meningeal irritation and inflammation rather than direct pressure within the skull.
D. Lethargy:
This is the correct answer. Lethargy, or excessive drowsiness or fatigue, can be an early manifestation of increased intracranial pressure. As pressure increases within the skull, it can lead to alterations in consciousness ranging from lethargy to coma. Monitoring the client for changes in level of consciousness, including lethargy, is important for early detection of increased intracranial pressure.
Correct Answer is C
Explanation
A. Check the client for a fecal impaction.
This intervention is important for managing autonomic dysreflexia because a fecal impaction can trigger autonomic dysreflexia by causing rectal distention. However, it is not the first action the nurse should take. Promptly addressing the immediate cause of autonomic dysreflexia is crucial to prevent complications.
B. Ensure the room temperature is warm.
This intervention is important for maintaining the client's comfort and preventing temperature-related complications. However, it is not the first action the nurse should take when suspecting autonomic dysreflexia. Immediate interventions to address the underlying cause of autonomic dysreflexia are necessary to prevent serious complications such as stroke or seizure.
C. Check the client's bladder for distention.
This is the correct action to take first. Bladder distention is one of the most common triggers of autonomic dysreflexia in individuals with spinal cord injuries. A distended bladder stimulates autonomic reflexes, leading to a sudden increase in blood pressure. Therefore, the nurse should assess the client's bladder for distention and initiate appropriate interventions such as catheterization to relieve urinary retention.
D. Raise the head of the bed.
While elevating the head of the bed can help reduce blood pressure in some situations, it is not the first action the nurse should take when suspecting autonomic dysreflexia. Elevating the head of the bed may exacerbate autonomic dysreflexia by increasing venous return and blood pressure. Therefore, addressing the underlying cause of autonomic dysreflexia, such as bladder distention, takes priority.
