NUR 230 Exam 4 Success Guide 2026 | Verified Questions &
Answers | Graded A+
1. Describe how medications can help in managing increased intracranial
pressure (ICP).
Medications can reduce ICP by decreasing fluid volume or
improving cerebral blood flow.
Medications only treat symptoms of ICP without addressing the cause.
Medications can increase ICP by promoting fluid retention.
Medications have no effect on ICP.
2. Describe the relationship between sudden loss of consciousness and
respiratory patterns in a clinical setting.
Respiratory patterns are unrelated to loss of consciousness.
Unusual respiratory patterns are a sign of dehydration.
Loss of consciousness only affects heart rate, not respiration.
Sudden loss of consciousness can lead to unusual respiratory
patterns due to impaired brain function.
3. Describe how changes in PCO2 and PO2 levels can affect vasodilation
during increased intracranial pressure.
Decreased levels of PCO2 cause vasodilation, while increased levels
of PO2 inhibit it.
Vasodilation is only affected by changes in PO2 levels.
Increased levels of PCO2 lead to vasodilation, while decreased
levels of PO2 can also contribute to this effect.
Constant levels of PCO2 and PO2 have no effect on vasodilation.
,4. What is the primary imaging technique used to diagnose a stroke?
MRI
CT scan
X-ray
Ultrasound
5. A patient suffering from a stroke should be positioned
in the supine position.
in the Trendelenburg position.
upright.
with the head slightly elevated.
6. What is the relationship between PCO2 levels and vasodilation in the context
of increased intracranial pressure?
variable
increased
decreased
constant
7. What are two tests commonly used to evaluate proprioception and
cerebellar function?
Mini-Mental State Examination and gait analysis
Romberg test and finger-to-nose test
Glasgow Coma Scale and cranial nerve assessment
CT scan and MRI
,8. What life-threatening condition can occur if an increase in intracranial
pressure (ICP) is significant enough?
Migraine
Herniation
Amnesia
Seizure
Visual disturbances
9. A patient receiving fibrinolytic therapy has a systolic blood pressure of 185
mmHg. What action should the healthcare provider take?
Administer antihypertensive medication to lower blood pressure.
Prepare for immediate surgery.
Increase the dosage of fibrinolytic therapy.
Continue monitoring without intervention.
10. If the volume of one of the 3 components of the cranium increases, the
volume of the others must decrease to maintain normal pressures in the
cavity. This is known as
Cushing's Triad
Starling's law
Pascal's law
Monro-Kellie hypothesis
11. The most likely group of people to suffer a traumatic brain injury are
Men between the ages of 15 and 24
, Women between the ages of 15 and 24
Men between the ages of 25 and 34
Women between the ages of 25 and 34
12. What is the typical symptom associated with a subarachnoid hemorrhagic
stroke?
Loss of consciousness
Numbness in the limbs
Sudden severe headache
Visual disturbances
13. What should the nurse do to prepare a patient for a lumbar puncture?
Sedate the patient with medication
Position the patient in a lateral recumbent position with the hips,
knees and neck flexed
Assess the patient for stroke before procedure
Withhold caffeine for 8 hours
14. If a patient exhibits signs of increased intracranial pressure before a lumbar
puncture, what should the nurse do?
Reassure the patient that everything is fine.
Proceed with the lumbar puncture as planned.
Administer pain medication before the procedure.
Notify the physician and delay the procedure.
