,NSG 121 Exam 4 Health Assessment Questions And Answers
2026/2027 HERZING UNIVERSITY
Q1. Which structures make up the central nervous system?
A) Brain and spinal cord
B) Cranial nerves and spinal nerves
C) Autonomic and somatic nerves
D) Sensory receptors and peripheral nerves
Correct Answer: A) Brain and spinal cord
Rationale: The central nervous system consists of the brain and spinal cord.
The peripheral nervous system includes structures outside the brain and
spinal cord.
Q2. Which division of the peripheral nervous system controls
voluntary skeletal muscle movement?
A) Parasympathetic nervous system
B) Sympathetic nervous system
C) Somatic nervous system
D) Autonomic nervous system
Correct Answer: C) Somatic nervous system
Rationale: The somatic nervous system controls voluntary skeletal muscle
activity, while the autonomic nervous system regulates involuntary
functions.
Q3. Which function is most strongly associated with the frontal
lobe?
A) Visual interpretation only
B) Voluntary motor control, judgment, and aspects of language
C) Primary interpretation of hearing
D) Coordination of equilibrium and posture
Correct Answer: B) Voluntary motor control, judgment, and aspects of
language
Rationale: The frontal lobe contributes to voluntary motor function,
executive functions such as judgment and reasoning, personality, and
language.
, Q4. Damage to the parietal lobe is most likely to affect which
function?
A) Interpretation of sensory information such as touch and pressure
B) Regulation of heart rate
C) Production of cerebrospinal fluid
D) Maintenance of blood glucose
Correct Answer: A) Interpretation of sensory information such as touch and
pressure
Rationale: The parietal lobe processes and interprets several forms of
sensory information, including touch, pressure, pain, and spatial awareness.
Q5. Which brain structure coordinates movement, balance, and
posture?
A) Frontal lobe
B) Cerebellum
C) Medulla
D) Temporal lobe
Correct Answer: B) Cerebellum
Rationale: The cerebellum coordinates voluntary movement and
contributes to balance, posture, and motor precision.
Q6. Which function is most closely associated with the brainstem?
A) Complex mathematical reasoning
B) Voluntary writing
C) Regulation of essential functions such as respiration and cardiac activity
D) Storage of long-term memories only
Correct Answer: C) Regulation of essential functions such as respiration and
cardiac activity
Rationale: The brainstem contains structures involved in maintaining vital
functions, including respiratory and cardiovascular regulation.
Q7. What is a primary function of the spinal cord?
A) Producing hormones
B) Transmitting neural information between the brain and the body
C) Producing red blood cells
D) Controlling digestion independently of the brain
