Extract:
A child with a head injury is at risk for increased intracranial pressure (ICP).
Question 1 of 5
Which change in status would alert the nurse to believe an increase in ICP has occurred?
Correct Answer: B
Rationale: The correct answer is B because increased diastolic pressure with narrowing pulse pressure is a classic sign of increased intracranial pressure (ICP). When ICP rises, it can lead to cerebral edema, causing a decrease in compliance within the cranial vault. This results in an increase in diastolic blood pressure due to the brain's inability to compensate for the increased pressure. The narrowing pulse pressure occurs because the increased diastolic pressure compensates for the decreased systolic pressure. Confusion and altered mental status (
A) can be seen with increased ICP but are not specific indicators. Irregular, rapid heartbeat (
C) and rapid, shallow breathing (
D) are not direct signs of increased ICP.
