Question 2
Regular
Which cranial nerve supplies most of the organs in the thoracic and abdominal cavities and carries motor fibers to glands that produce digestive juices and other secretions?
Correct!
Incorrect
The correct answer is: D
Rationale
D: Vagus nerve. The vagus nerve is essential for autonomic control, innervating most thoracic and abdominal organs, and facilitating motor functions for glands that secrete digestive juices and other substances.
A: Somatic motor nerve. This type of nerve primarily regulates voluntary movements of skeletal muscles, lacking the autonomic functions required for organ and glandular innervation in the thoracic and abdominal cavities.
B: Visceral sensory nerve. This nerve type transmits sensory information from internal organs to the central nervous system, but does not provide motor fibers or innervate glands in the thoracic and abdominal areas.
C: Abducens nerve. Primarily responsible for eye movement, this cranial nerve does not play a role in supplying organs or glands in the thoracic or abdominal cavities.

Question 5
Regular
Which sign is the cardinal sign of increased intracranial pressure in a patient who has sustained a brain injury?
Correct!
Incorrect
The correct answer is: D
Rationale
Decrease in the level of consciousness. This sign indicates impaired brain function due to increased intracranial pressure, leading to altered mental status and responsiveness following a brain injury, reflecting severity.
A: Pupil changes. While changes in pupils can indicate pressure effects, they are not as definitive as altered consciousness in demonstrating severe intracranial pressure impacts on brain function.
B: Ipsilateral paralysis. This symptom may suggest localized brain damage but does not universally indicate increased intracranial pressure, as it pertains to specific areas rather than global brain function.
C: Vomiting. Although vomiting can occur with increased intracranial pressure, it is a nonspecific symptom that can arise from various causes, lacking the direct correlation to consciousness level.

Question 6
Regular
The nurse is aware that when assessing a patient by the FOUR score coma scale, the patient is assessed in four categories: eye response, brainstem reflexes, motor response, and respiration. In which manner are these results reported?
Correct!
Incorrect
The correct answer is: C
Rationale
The results are reported as individual scores in each category. Each category of the FOUR score coma scale provides specific insights into the patient's neurological status, allowing for a detailed assessment of their condition and response mechanisms. This individual reporting supports targeted interventions and monitoring of patient progress effectively.
A: As a sum of the scores of the four categories. Summing the scores does not capture the distinct contributions of each assessment area, which are crucial for comprehensive evaluation.
B: As part of the Glasgow Coma Scale. The FOUR score coma scale is a separate assessment tool, distinct from the Glasgow Coma Scale, focusing on different criteria and scoring methodology.
D: As progressive scores during a 24-hour period. Reporting progressive scores would imply continuous tracking over time rather than the immediate assessment of individual responses within the four categories.

Question 23
Regular
The nurse is aware that the drug t-PA a tissue plasminogen activator, must be given within how many hours of the onset of symptoms to have maximum benefit?
Correct!
Incorrect
The correct answer is: A
Rationale
t-PA must be administered within 3 hours of symptom onset for optimal effectiveness. This time frame is critical as it significantly improves outcomes in patients experiencing acute ischemic strokes by facilitating clot dissolution.
B: 4 hours. While 4 hours is a common threshold for some treatments, t-PA specifically requires administration within the narrower window of 3 hours to maximize patient benefits.
C: 6 hours. Administering t-PA after 6 hours diminishes its efficacy in dissolving clots, leading to poorer recovery outcomes and increased risks of complications for the patient.
D: 8 hours. A delay of 8 hours far exceeds the recommended window for t-PA, rendering it ineffective and increasing the chances of long-term disability from a stroke.

A ___ is a diagnostic procedure used to identify lesions by observing the flow of radiopaque dye through the subarachnoid space.
Correct!
Incorrect
The correct answer is: MYELOGRAM
Rationale
A myelogram is a diagnostic procedure used to identify lesions by observing the flow of radiopaque dye through the subarachnoid space. This technique allows visualization of the spinal cord and nerve roots, aiding in the detection of abnormalities such as tumors or herniated discs through imaging that showcases the distribution of the dye within the cerebrospinal fluid.
A: CT scan. This imaging technique does not specifically involve the use of radiopaque dye in the subarachnoid space, focusing instead on cross-sectional views of body structures.
B: MRI. Magnetic resonance imaging utilizes magnetic fields and radio waves rather than radiopaque dyes, making it unsuitable for directly observing the flow through the subarachnoid space.
C: X-ray. Standard X-rays provide limited detail regarding soft tissues and fluid movement, lacking the specificity necessary to visualize lesions in the subarachnoid space effectively.

Question 43
Calculation(ans only)
The nurse explains to a patient and family that the triad of signs of Parkinson disease is: ___, rigidity, and bradykinesia.
Correct!
Incorrect
The correct answer is: TREMOR
Rationale
Tremor. The triad of signs characteristic of Parkinson's disease includes tremor, rigidity, and bradykinesia, which collectively help in diagnosing this neurodegenerative disorder and understanding its motor symptoms.
B: Stiffness Stiffness specifically describes a sensation rather than a measurable clinical sign, failing to encompass the rhythmic oscillations indicated by tremor, which are essential in Parkinson's diagnosis.
C: Dizziness Dizziness does not relate to the core motor symptoms of Parkinson's disease and instead pertains to balance issues, which are not part of the classic triad of signs.
D: Weakness Weakness may occur in various conditions, but it does not specifically identify the hallmark signs of Parkinson's disease, which focus on tremor, rigidity, and bradykinesia.

Question 44
Calculation(ans only)
Involuntary rhythmic movement of the eyes, with oscillations that may be horizontal, vertical, or mixed movements, is called ___
Correct!
Incorrect
The correct answer is: NYSTAGMUS
Rationale
Nystagmus.
Nystagmus refers to the involuntary, rhythmic oscillations of the eyes characterized by horizontal, vertical, or mixed movements. This phenomenon can occur during various conditions, including vestibular disorders, and often indicates underlying neurological or physiological issues that affect visual stability and coordination.
A: strabismus. Strabismus involves misalignment of the eyes rather than the rhythmic movement associated with nystagmus. It primarily affects binocular vision and is not characterized by involuntary oscillations.
B: saccades. Saccades represent rapid eye movements that shift focus between points instead of the continuous oscillatory motion seen in nystagmus. They are voluntary and not rhythmic.
C: amblyopia. Amblyopia, or "lazy eye," is a visual developmental disorder where one eye fails to achieve normal vision, lacking the rhythmic movement characteristic of nystagmus. This condition involves reduced visual acuity rather than eye oscillations.

Question 45
Calculation(ans only)
The waxy substance that covers the neuron fibers and increases the rate of transmission of impulses is the ___
Correct!
Incorrect
The correct answer is: MYELIN
Rationale
Myelin.
Myelin serves as an insulating layer around neuron fibers, significantly enhancing the speed of electrical impulse transmission. This fatty substance facilitates rapid communication between neurons, which is crucial for efficient nervous system function. Its presence is vital for maintaining the overall health and performance of the nervous system, allowing for quick reflexes and coordinated movements.
A: axon Sheath does not specifically refer to the fatty insulation that speeds up impulse transmission; it denotes the overall structure of the neuron.
B: dendrite While dendrites receive signals from other neurons, they do not play a role in insulating or speeding up the impulse transmission process.
C: synapse The synapse is the junction between neurons where signals are transmitted, but it does not involve the insulating properties necessary for faster impulse conduction.
