Review of Systems Neurological Questions Questions
Question 1 of 5
What is the relationship between dorso-ventral patterning of the neural tube and patterning of the somites?
Correct Answer: C
Rationale: Dorso-ventral patterning of the neural tube and somites is regulated by opposing gradients of Sonic hedgehog (Shh) from the notochord and floorplate (ventralizing signals) and BMPs from the dorsal neural tube (dorsalizing signals). These signals coordinate the development of both structures, ensuring proper alignment and function of the nervous system and musculoskeletal system.
Question 2 of 5
A client is admitted with a head injury. To monitor hypothalamic function, the nurse should monitor what parameters?
Correct Answer: A
Rationale: The hypothalamus regulates body temperature and fluid balance, making temperature and urinary output key parameters to monitor in head injury patients. Hypothalamic dysfunction can lead to disorders like diabetes insipidus or syndrome of inappropriate antidiuretic hormone (SIADH), affecting fluid balance and temperature regulation.
Question 3 of 5
The nurse is explaining the transmission of nerve impulses to a patient with a spinal cord injury. What should the nurse explain as the structure that carries nerve impulses at synapses?
Correct Answer: D
Rationale: Neurotransmitters are chemicals released at the synaptic end bulb of a neuron that carry nerve impulses across the synapse to the next neuron. The cell membrane and depolarizations are involved in the electrical aspect of impulse transmission, while Schwann cells form the myelin sheath. Neurotransmitters are key to understanding synaptic communication.
Question 4 of 5
The nurse is preparing a patient for an electroencephalogram (EEG). What information should be given to the patient?
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 of 5
The nurse is preparing to conduct a Romberg test with a patient. For how many seconds should the nurse explain to the patient that the position will need to be held?
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
