ATI Neurological System Questions Questions
Question 1 of 5
Nerve cells form long projections called ________.
Correct Answer: B
Rationale: The correct answer is B: axons. Nerve cells form long projections called axons to transmit electrical impulses away from the cell body. Axons are essential for communicating signals between different parts of the nervous system. Soma (A) refers to the cell body of the neuron, dendrites (C) are short, branched extensions that receive signals, and synapses (D) are the junctions where neurons communicate with each other, not the long projections themselves. Therefore, axons are the correct choice for the long projections formed by nerve cells.
Question 2 of 5
A patient has a severed spinal nerve as a result of trauma. Which statement is true in this situation?
Correct Answer: C
Rationale: Rationale for Correct Answer (C): When a spinal nerve is severed, adjacent spinal nerves can compensate and continue to carry sensations for the dermatome served by the severed nerve. This is possible due to the concept of dermatomes overlapping and the redundancy in sensory innervation. Therefore, the patient may still experience sensation in the affected area despite the specific nerve being severed. Summary of Incorrect Choices: A: Incorrect. Even if there are 31 pairs of spinal nerves, severing one nerve can still have a significant impact on sensory and motor functions depending on the location and severity of the injury. B: Incorrect. Sensory loss would occur in the dermatome served by the severed nerve, but adjacent nerves can still carry sensations. D: Incorrect. Spinal nerves have both sensory and motor components, so severing a spinal nerve can affect both sensory and motor functions, not just motor function.
Question 3 of 5
A patient with blindness related to a functional neurological (conversion) disorder says, All the doctors and nurses in this hospital stop by often to check on me. Too bad people outside the hospital don't find me interesting. Which nursing diagnosis is most relevant?
Correct Answer: B
Rationale: The correct answer is B: Chronic low self-esteem. The patient's statement reflects a negative self-perception and feelings of inadequacy, indicating low self-esteem. Social isolation (A) would imply a lack of social interactions, which is not indicated in the scenario. Interrupted family processes (C) would involve disruptions in family relationships, which are not mentioned. Ineffective health maintenance (D) pertains to the inability to manage health conditions, which is not relevant to the patient's statement. Chronic low self-esteem best aligns with the patient's expressed feelings of being uninteresting and not valued by others.
Question 4 of 5
A nurse counseling a patient diagnosed with dissociative identity disorder (DID) should understand that the assessment of highest priority is:
Correct Answer: A
Rationale: The correct answer is A: risk for self-harm. In patients with DID, the primary concern is ensuring their safety due to the high risk of self-harm or suicide. Assessing this risk is crucial for immediate intervention to prevent harm. Choice B, cognitive functioning, may be important but is secondary to ensuring patient safety. Choice C, identification of drug abuse, is relevant but not as urgent as addressing the risk for self-harm. Choice D, readiness to reestablish identity or memory, is important but not as critical as ensuring the patient's safety. Therefore, assessing the risk for self-harm takes precedence in the care of a patient with DID.
