Medical Surgical Nursing: Neurological Disorders Practice Exam Study Guide
2026/2027
• This 200-question practice exam covers all core neurological nursing topics to help
you master Med-Surg Neuro concepts through active recall, with each question
featuring five options (A–E), a clearly highlighted correct answer, and a EXPERT
RATIONALE to reinforce your understanding.
• Use this guide by attempting each question independently before checking the
answer and EXPERT RATIONALE — spacing your review sessions and revisiting
missed questions will maximize retention and exam readiness.
SECTION 1: NEUROLOGICAL ANATOMY & PHYSIOLOGY
1. Which part of the brain is primarily responsible for coordinating voluntary
muscle movement and maintaining balance?
A. Cerebrum
B. Medulla oblongata
C. Hypothalamus
D. Cerebellum
E. Thalamus
Correct Answer: D. Cerebellum EXPERT RATIONALE: The cerebellum
coordinates voluntary movements, balance, and fine motor control. Damage to the
cerebellum results in ataxia, dysmetria, and intention tremors.
2. The blood-brain barrier (BBB) is primarily maintained by which of the
following cells?
,A. Microglia
B. Oligodendrocytes
C. Ependymal cells
D. Astrocytes
E. Schwann cells
Correct Answer: D. Astrocytes EXPERT RATIONALE: Astrocytes form the
structural and functional basis of the blood-brain barrier by surrounding capillary
endothelial cells with foot processes, regulating what substances enter the CNS.
3. Which cranial nerve is responsible for the gag reflex?
A. CN VII (Facial)
B. CN V (Trigeminal)
C. CN IX (Glossopharyngeal)
D. CN XI (Accessory)
E. CN XII (Hypoglossal)
Correct Answer: C. CN IX (Glossopharyngeal) EXPERT RATIONALE: CN IX
(Glossopharyngeal) along with CN X (Vagus) mediates the gag reflex. CN IX is the
afferent limb (sensory) and CN X is the efferent limb (motor).
4. Cerebrospinal fluid (CSF) is primarily produced by which structure?
A. Arachnoid villi
B. Dura mater
C. Pia mater
D. Choroid plexus
E. Corpus callosum
, Correct Answer: D. Choroid plexus EXPERT RATIONALE: The choroid plexus,
located in the ventricles of the brain, produces approximately 500 mL of CSF per
day, with about 150 mL circulating at any given time.
5. The primary motor cortex is located in which lobe of the brain?
A. Temporal lobe
B. Occipital lobe
C. Parietal lobe
D. Frontal lobe
E. Insular lobe
Correct Answer: D. Frontal lobe EXPERT RATIONALE: The primary motor
cortex is located in the precentral gyrus of the frontal lobe and controls voluntary
motor movement of the contralateral side of the body.
6. A nurse assesses a patient's pupillary response. Which cranial nerve
controls pupillary constriction?
A. CN II (Optic)
B. CN III (Oculomotor)
C. CN IV (Trochlear)
D. CN VI (Abducens)
E. CN V (Trigeminal)
Correct Answer: B. CN III (Oculomotor) EXPERT RATIONALE: CN III
(Oculomotor) controls pupillary constriction via the parasympathetic fibers. A blown
(dilated, nonreactive) pupil is a classic sign of CN III compression, often seen with
herniation.
, 7. Which area of the brain regulates temperature, hunger, thirst, and the
sleep-wake cycle?
A. Thalamus
B. Cerebellum
C. Basal ganglia
D. Hypothalamus
E. Amygdala
Correct Answer: D. Hypothalamus EXPERT RATIONALE: The hypothalamus
is the master regulator of homeostasis, controlling body temperature, hunger,
thirst, circadian rhythms, and the autonomic nervous system.
8. Normal intracranial pressure (ICP) in an adult at rest is:
A. 1–5 mmHg
B. 5–15 mmHg
C. 20–30 mmHg
D. 30–40 mmHg
E. 40–50 mmHg
Correct Answer: B. 5–15 mmHg EXPERT RATIONALE: Normal ICP ranges
from 5–15 mmHg. Values consistently above 20 mmHg are considered elevated and
require intervention to prevent secondary brain injury.
9. The Monro-Kellie doctrine states that an increase in one intracranial
component must be compensated by:
A. An increase in cerebral blood flow
B. A decrease in one or more of the other components
C. An increase in CSF production
