Health Assessment Neurological System Questions Questions
Question 1 of 5
The 'synaptic cleft' of a neuromuscular junction is
Correct Answer: D
Rationale: The synaptic cleft is the narrow space between the presynaptic neuron and the postsynaptic muscle cell. It is where neurotransmitters are released and diffuse to bind receptors on the muscle cell, initiating muscle contraction. This structure is essential for signal transmission at the neuromuscular junction.
Question 2 of 5
There are _____ ventricles in the brain.
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
The nurse is caring for an individual with a head injury and notes unequal pupils. Which term should the nurse use to document this finding?
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
A patient who is severely brain damaged has decerebrate posturing with extended extremities. In which area of the brain should the nurse suspect the patient has sustained damage?
Correct Answer: B
Rationale: Decerebrate posturing, characterized by extended extremities, indicates damage to the brainstem, particularly the midbrain or pons. The cerebrum, cerebellum, and hypothalamus are not directly associated with this type of posturing. Recognizing decerebrate posturing is critical for assessing the severity of brain injury.
Question 5 of 5
The neuron cell is made up of which of the following parts?
Correct Answer: D
Rationale: A neuron consists of an axon, which transmits signals away from the cell body; dendrites, which receive signals; and a nucleus, which contains genetic material. All these parts work together to enable the neuron to communicate effectively. This comprehensive structure allows neurons to perform their critical role in the nervous system.
