NSG3160 | NSG3160 Health Assessment Exam 3
Version 1 Questions with Correct Answers and
Expert Explanation for All Question
1. When assessing the Glasgow Coma Scale (GCS), which three components are
evaluated to determine a patient’s neurological status?
A. Eye opening, verbal response, and motor response
B. Blood pressure, heart rate, and respiratory rate
C. Pupillary reaction, gait, and reflex intensity
D. Mental status, cranial nerve function, and sensory perception
Correct Answer: A
Expert Explanation: The Glasgow Coma Scale is a standardized tool used to assess
a patient’s level of consciousness by evaluating three specific responses. These
categories include eye opening, verbal response, and motor response, which are
each assigned a numerical score. A total score of 15 indicates full consciousness,
while a score of 3 represents the lowest possible functional level. Nurses use this
scale to provide objective data regarding neurological changes over time in acute
care settings. This assessment is critical for identifying early signs of brain injury or
deteriorating neurological function.
,2. A nurse asks a patient to stick out their tongue and move it from side to side. Which
cranial nerve is being assessed?
A. Cranial Nerve IX (Glossopharyngeal)
B. Cranial Nerve X (Vagus)
C. Cranial Nerve XII (Hypoglossal)
D. Cranial Nerve XI (Spinal Accessory)
Correct Answer: C
Expert Explanation: Cranial Nerve XII, the hypoglossal nerve, is primarily
responsible for controlling the motor functions of the tongue. To assess this nerve,
the nurse observes the tongue for symmetry, tremors, and the ability to move
against resistance. If the tongue deviates to one side when protruded, it may
indicate a lesion or damage to that specific nerve. This assessment is vital for
ensuring the patient can safely clear their airway and manipulate food during
swallowing. Monitoring the hypoglossal nerve helps detect neurological deficits that
could lead to significant speech or nutritional complications.
3. Which assessment technique is most appropriate for testing a patient’s cerebellar
function and coordination?
A. Checking the deep tendon reflexes at the patella
B. Performing the finger-to-nose test
,C. Testing the patient’s ability to identify a smell
D. Assessing the patient’s level of orientation
Correct Answer: B
Expert Explanation: The cerebellum is the part of the brain responsible for
voluntary motor coordination, equilibrium, and muscle tone. The finger-to-nose test
requires the patient to touch the nurse’s finger and then their own nose repeatedly
and accurately. Smooth and coordinated movements suggest that the cerebellum is
functioning correctly without impairment. Inability to perform this task may
indicate cerebellar ataxia or the presence of lesions in the posterior fossa. Nurses
utilize this coordination check to evaluate for potential neurological damage caused
by stroke or alcohol toxicity.
4. During a neurological exam, the nurse notes the patient exhibits decerebrate
posturing. What does this finding typically indicate?
A. A lesion in the cerebral cortex
B. A localized spinal cord injury
C. A normal response to painful stimuli
D. Injury to the midbrain or brainstem
Correct Answer: D
, Expert Explanation: Decerebrate posturing is characterized by the stiff extension
of the arms and legs, with toes pointed downward and the head arched back. This
specific positioning usually indicates severe damage to the upper brainstem or
midbrain area. It is considered a more ominous sign than decorticate posturing
because it suggests deeper neurological involvement. Prompt recognition of this
abnormal motor response is essential for the nurse to initiate emergency
interventions and stabilize the patient. Ongoing monitoring for changes in posturing
helps clinical teams evaluate the progression or resolution of increased intracranial
pressure.
5. Which cranial nerve is responsible for the sensation of the face and the motor
function of the muscles of mastication?
A. Cranial Nerve III (Oculomotor)
B. Cranial Nerve V (Trigeminal)
C. Cranial Nerve VII (Facial)
D. Cranial Nerve IX (Glossopharyngeal)
Correct Answer: B
Expert Explanation: Cranial Nerve V, the trigeminal nerve, has both sensory and
motor components that serve the facial structures. The sensory portion allows for
the perception of touch, pain, and temperature across the forehead, cheeks, and jaw.
