Neurological System Assessment Questions Questions
Question 1 of 5
How does lateral inhibition work to specify individual neurons in the neural epithelium of invertebrates and vertebrates?
Correct Answer: A
Rationale: Lateral inhibition involves the Delta-Notch signaling pathway, where one cell in a cluster of prospective neurons becomes dominant by expressing higher levels of Delta. This cell inhibits its neighbors from adopting a neuronal fate through Notch signaling, ensuring that only a subset of cells differentiate into neurons. This mechanism is crucial for creating the precise pattern of neuronal distribution in the developing nervous system.
Question 2 of 5
A nurse is preparing a client for an MRI. Which factor would exclude the client from the test?
Correct Answer: B
Rationale: A cardiac pacemaker is a contraindication for MRI due to the strong magnetic fields, which can interfere with the device's function and pose a risk to the patient. Other contraindications include metallic implants or foreign bodies. Claustrophobia and jewelry are not absolute contraindications but may require special considerations.
Question 3 of 5
The nurse is reviewing the vital sign measurements for a patient with a neurological problem. When analyzing these measurements, what should the nurse recall as the part of the brain that regulates heart rate and blood pressure?
Correct Answer: A
Rationale: The medulla oblongata, located in the brainstem, contains cardiac and vasomotor centers that regulate heart rate and blood pressure. The cerebrum is responsible for higher cognitive functions, the cerebellum for coordination, and the hypothalamus for maintaining homeostasis. The medulla's role in vital functions makes it critical in neurological assessments.
Question 4 of 5
The nurse is caring for a patient who has impaired functioning of the left glossopharyngeal (IX) nerve and the vagus (X) nerve. What intervention should the nurse plan to maintain the patient's safety while diagnostic testing is being completed?
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 of 5
A patient opens the eyes to painful stimuli, makes incomprehensible sounds, and withdraws from pain. What should the nurse calculate this patient's Glasgow Coma Scale score to be?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
