Using the Glasgow Coma Scale, the nurse notes that the client Rationale: The client has a score of 6 (eye opening to pain=2; ver-

A. Unequal pupil size
A client is at risk for Increased intracranial pressure (ICP). Which
finding is priority for the nurse to monitor?
Rationale: Increasing ICP causes unequal pupils as a result of
pressure on the third cranial nerve. Increasing ICP causes an
A. Unequal pupil size
increase in systolic BP, which reflects the additional pressure
B. Decreasing systolic blood pressure

body temperature from hypothalamic damage.
Which respiratory pattern indicates increasing ICP in the brain A. Slow, irregular respirations
stem?
Rationale: Neural control of respiration takes place in the brain
A. Slow, irregular respirations stem. Deterioration and pressure produce slow and irregular

C. Encourage the client to take deep breaths to hyperventilate
Rationale: Normal ICP is 15mmHg or less for 15 to 30 seconds or
A client has an increased ICP of 20mmHg. The nurse should: longer. Hyperventilation causes vasoconstriction, which reduces
cerebrospinal fluid and blood volume, two important factors for
A. Give the client a warming blanket reducing a sustained ICP of 20mmHg. A cooling blanket is used
B. Administer low-dose barbiturates to control the elevation of temperature because a fever increases
C. Encourage the client to take deep breaths to hyperventilate the metabolic rate, which in turn increases ICP. High doses of bar-

demands. Fluid volume and inotropic drugs are used to maintain
cerebral perfusion by supporting the cardiac output and keeping
the cerebral perfusion pressure >80mmHg.
The nurse is assessing a client with increasing ICP. The nurse D. Decrease in the level of consciousness (LOC)
should notify the healthcare provider about which early change in
the client's condition?
Rationale: A decrease in the client's LOC is an early indicator of
deterioration of the client's neurological status. Changes in LOC,
A. Widening pulse pressure
such as restlessness and irritability, may be subtle. Widening of

D. Decrease in the level of consciousness (LOC)
Which activity should the nurse encourage the client to avoid when
C. Coughing
there is a risk for increased ICP?
Rationale: Coughing is contraindicated for a client at risk for in-
A. Deep breathing
creased ICP because coughing increases ICP. Deep breathing

The nurse is assessing a client for decerebrate posturing. The D. Back arched and rigid extension of all four extremities
nurse should assess the client for:
Rationale: Decerebrate posturing occurs in clients with damage
A. Internal rotation and adduction of the arms with flexion of the to the upper brain stem, midbrain, or pons and is demonstrated
