Exam 3 Review Questions & Answers_ Latest 2026-2027.
1. A nurse is caring for a patient at risk for increased intracranial pressure
(ICP). Which ICP reading is considered within the normal range?
A. 20–25 mmHg
B. 5–8 mmHg
C. 10–15 mmHg
D. 25–30 mmHg
Correct Answer: C. 10–15 mmHg
Rationale: The study guide identifies normal ICP as 10–15 mmHg and notes that pressures
above 20 mmHg can impair cerebral circulation.
2. Which assessment finding is considered the earliest indication of increasing
ICP?
A. Papilledema
B. Bradycardia
C. Declining level of consciousness
D. Decerebrate posturing
Correct Answer: C. Declining level of consciousness
Rationale: A declining or changing LOC—such as restlessness, confusion, or
disorientation—is identified as the first sign of increasing ICP.
3. Which group of findings represents Cushing's triad?
A. Hypotension, tachycardia, and tachypnea
B. Severe hypertension, widened pulse pressure, and bradycardia
C. Bradycardia, hypotension, and fever
D. Hypertension, tachycardia, and narrowed pulse pressure
Correct Answer: B. Severe hypertension, widened pulse pressure, and bradycardia
Rationale: Cushing's triad is a late sign of severe ICP and consists of hypertension,
widening pulse pressure, and bradycardia.
4. Which position is most appropriate for a patient with increased ICP?
,A. Flat with the neck flexed
B. Trendelenburg with the head rotated
C. HOB elevated 30–45 degrees with the head midline and neutral
D. High Fowler's with the hips sharply flexed
Correct Answer: C. HOB elevated 30–45 degrees with the head midline and neutral
Rationale: Elevating the HOB and maintaining neutral head alignment promotes venous
drainage and helps reduce ICP.
5. Which nursing action should be avoided in a patient with increased ICP?
A. Clustering multiple care activities together
B. Maintaining a quiet environment
C. Using a stool softener
D. Keeping the head in neutral alignment
Correct Answer: A. Clustering multiple care activities together
Rationale: The materials specifically warn against clustering care because repeated
stimulation can increase ICP.
6. Why is mannitol administered to a patient with cerebral edema?
A. To increase CSF production
B. To stimulate acetylcholine receptors
C. To increase cerebral vasodilation
D. To draw fluid from cerebral tissue into the vascular space
Correct Answer: D. To draw fluid from cerebral tissue into the vascular space
Rationale: Mannitol is an osmotic diuretic that pulls fluid into the vascular space and
reduces cerebral edema and ICP.
7. Which finding best indicates that mannitol is producing the expected effect?
A. Decreased respiratory rate
B. Decreased temperature
C. Increased urinary output
D. Increased pulse pressure
Correct Answer: C. Increased urinary output
Rationale: Increased urine output reflects the osmotic diuretic action of mannitol.
, 8. A patient has a Glasgow Coma Scale score of 7. How should the nurse classify
this injury?
A. Mild
B. Moderate
C. Severe
D. Normal
Correct Answer: C. Severe
Rationale: A GCS score of 3–8 is classified as severe head injury and is associated with
coma.
9. Which change in Glasgow Coma Scale requires immediate notification of the
healthcare provider?
A. Increase from 13 to 14
B. Increase from 8 to 9
C. No change during two assessments
D. A change of 2 points
Correct Answer: D. A change of 2 points
Rationale: The Exam 3 study guide specifically states that a 2-point GCS change requires
immediate notification.
10. Which finding is most characteristic of an epidural hematoma?
A. Slow venous bleeding over several months
B. No alteration in consciousness
C. Bleeding within the brain tissue
D. An arterial bleed with a lucid interval
Correct Answer: D. An arterial bleed with a lucid interval
Rationale: Epidural hematoma is described as arterial bleeding between the dura and skull
and may produce a characteristic lucid interval.
11. Which statement correctly describes a subdural hematoma?
A. It is always caused by arterial bleeding.
B. It occurs only inside brain tissue.
C. It involves venous bleeding beneath the dura.
D. It cannot become chronic.
