MULTIPLE CHOICE

144/90 mm Hg, and her mean arterial pressure (MAP) is 108 mm Hg. What is the cerebral perfusion
pressure (CPP)?

care, and reposition the patient to the left side. What is the best action by the nurse?

d. Suction the left nares until the drainage clears.

6. The nurse is caring for a patient who was hit on the head with a hammer. The patient was unconscious at

15. One hour later, the nurse assesses a GCS score of 3. What is the priority nursing action?

a. Stimulate the patient hourly.

b. Continue to monitor the patient.

c. Elevate the head of the bed.

d. Notify the physician immediately.

7. The nurse is caring for a patient with an ICP of 18 mm Hg and a GCS score of 3. Following the
administration of mannitol (Osmitrol), which assessment finding by the nurse requires further
action?


a. ICP of 10 mm Hg

b. CPP of 70 mm Hg

c. GCS score of 5

d. CVP of 2 mm


Hg
The nurse is caring for a mechanically ventilated patient with a brain injury. Arterial blood gas values
indicate a PaCO2 of 60 mm Hg. The nurse understands this value to have which effect on cerebral blood
flow?

a. Altered cerebral spinal fluid production and reabsorption

b. Decreased cerebral blood volume due to vessel constriction

c. Increased cerebral blood volume due to vessel dilation


d. No effect on cerebral blood flow (PaCO2 of 60 mm Hg is


normal)
8. The nurse assesses a patient with a skull fracture to have a Glasgow Coma Scale score of 3. Additional
vital signs assessed by the nurse include blood pressure 100/70 mm Hg, heart rate 55 beats/min, respiratory
rate 10 breaths/min, oxygen saturation (SpO2) 94% on oxygen at 3 L per nasal cannula. What is the priority
nursing action?

,a. Monitor the patients airway patency.

b. Elevate the head of the patients bed.

c. Increase supplemental oxygen delivery.

d. Support bony prominences with padding.

9. The nurse is caring for a patient who has a diminished level of consciousness and who is mechanically
ventilated. While performing endotracheal suctioning, the patient reaches up in an attempt to grab the
suction catheter. What is the best interpretation by the nurse?


a. The patient is exhibiting extension posturing.

b. The patient is exhibiting flexion posturing.

c. The patient is exhibiting purposeful movement.

d. The patient is withdrawing to stimulation.

10. The nurse is caring for a patient admitted to the ED following a fall from a 10-foot ladder. Upon
admission the nurse assesses the patient to be awake, alert, and moving all four extremities. The nurse also

b. Monitor airway patency.

c. Maintain neutral head position.

d. Apply a small nasal drip pad.

c. Maintain neutral head alignment and avoid extreme hip flexion.

d. Reduce ambient room temperature and administer antipyretics.
