Lethargy
A nurse working on a medical-surgical floor walks into a patient's room to find the patient with an altered level of consciousness (LOC). Which of the following actions would be the first priority?
Maintenance of a patent airway
The most frequently administered hyperosmotic agent used to reduce cerebral edema before intracranial surgery is
Mannitol

Rising blood pressure and bradycardia
A client is receiving hypothermic treatment for uncontrolled fever related to increased intracranial pressure (ICP). Which assessment finding requires immediate intervention?
Shivering
A client with increased intracranial pressure has a cerebral perfusion pressure (CPP) of 40 mm Hg. How should the nurse interpret the CPP value?
The CPP is low.Explanation: The normal CPP is 70 to 100 mm Hg.
During assessment of an unconscious patient, the nurse notes "fixed, dilated pupils" and understands that brain injury is at the level of the midbrain.
True
The earliest sign of increasing ICP is a change in LOC.
True
Which method is used to help reduce intracranial pressure?
Using a cervical collar
A client with a traumatic brain injury has developed increased intracranial pressure resulting in diabetes insipidus. The expected treatment would consist of which of the following?
Vasopressin therapy
Which finding indicates increasing intracranial pressure (ICP) in the client who has sustained a head injury?
Widened pulse pressure
A nurse is monitoring a client for increasing intracranial pressure (ICP). Early signs of increased ICP include:
diminished responsiveness.
For a client with suspected increased intracranial pressure (ICP), an appropriate respiratory goal is to?
promote carbon dioxide elimination
The nurse is caring for a client immediately after supratentorial intracranial surgery. The nurse performs the appropriate action by placing the patient in the
supine position with the head slightly elevated.
A nurse is assessing a client who has been in a motor vehicle collision. The client directly and accurately answers questions. The nurse notes a contusion to the client's forehead; the client reports a headache. Assessing the client's pupils, what reaction would confirm increasing intracranial pressure?
unequal response
A client suffered a closed head injury in a motor vehicle collision, and an ICP monitor was inserted. In the occurrence of increased ICP, what physiologic function contributes to the increase in intracranial pressure?
vasodilation
A client with a head injury is being monitored for increased intracranial pressure (ICP). His blood pressure is 90/60 mm Hg and the ICP is 18 mm Hg; therefore his cerebral perfusion pressure (CPP) is:
52 mm Hg. 60x2= 120 120 +90 =210 210/ 3= 70 mm hg (map) 70-18 = 52 mmhg (MAP- ICP = CPP
A patient is admitted to the hospital with an ICP reading of 20 mm Hg and a mean arterial pressure of 90 mm Hg. What would the nurse calculate the CPP to be?
70 mm Hg
A client with a traumatic brain injury is showing early signs of increasing intracranial pressure (ICP). While planning care for this client, what would be the priority expected outcome?
Airway
Which is a late sign of increased intracranial pressure (ICP)?
Altered respiratory patterns
refers to the brain's ability to change the diameter of its blood vessels to maintain a constant cerebral blood flow during alterations in systemic blood pressure
Autoregulation
When caring for a client who is post-intracranial surgery what is the most important parameter to monitor?
Body temperature
A client with a traumatic brain injury has developed increased intracranial pressure resulting in diabetes insipidus. While assessing the client, the nurse expects which of the following findings?
Excessive urine output and decreased urine osmolality
A patient has a severe neurologic impairment from a head trauma. What does the nurse recognize is the type of posturing that occurs with the most severe neurologic impairment?
Flaccid
The nurse is caring for a patient postoperatively after intracranial surgery for the treatment of a subdural hematoma. The nurse observes an increase in the patient's blood pressure from the baseline and a decrease in the heart rate from 86 to 54. The patient has crackles in the bases of the lungs. What does the nurse suspect is occurring?
Increased ICP
The nurse is caring for a client with a ventriculostomy. Which assessment finding demonstrates effectiveness of the ventriculostomy?
Increased ICP is 12 mm Hg.
Nursing intervention when caring for a patient with ICP is to maintain the head of the bed at 30 degrees and maintain alignment of the head.
