Questions to Ask About Neurological System Questions
Question 1 of 5
Which of these statements about the peripheral nervous system is correct?
Correct Answer: D
Rationale: The correct answer is D because the peripheral nerves carry sensory input to the central nervous system by afferent fibers and motor commands away from the central nervous system by efferent fibers. This is known as the afferent-efferent division of the peripheral nervous system. Choice A is incorrect because cranial nerves (CNs) enter the brain directly, not through the spinal cord. Choice B is incorrect because efferent fibers carry motor commands away from the central nervous system, not sensory input. Choice C is incorrect because peripheral nerves are outside the central nervous system and do not carry impulses through motor fibers; instead, they carry motor commands through efferent fibers.
Question 2 of 5
A person comes to the clinic reporting, I wear a scarf across my lower face when I go out but because of my ugly appearance. Assessment reveals an average appearance with no actual disfigurement. Which problem is most likely?
Correct Answer: B
Rationale: The correct answer is B: Body dysmorphic disorder. This individual's distorted belief about their appearance despite no actual disfigurement aligns with the symptoms of body dysmorphic disorder. People with this disorder obsess over perceived flaws in their appearance. Incorrect choices: A: Dissociative identity disorder involves multiple distinct personality states, not related to body image. C: Pseudocyesis is a false belief of being pregnant, unrelated to body image. D: Malingering involves feigning symptoms for external gain, not related to distorted body image perceptions.
Question 3 of 5
What does an abnormal finding in the assessment of cranial nerve VII (Facial nerve) indicate?
Correct Answer: A
Rationale: Facial asymmetry or difficulty with facial expressions indicates dysfunction of cranial nerve VII (Facial nerve). Clear facial movements, normal taste sensation, and equal pupils are normal findings.
Question 4 of 5
A patient exhibits sudden, severe headache and neck stiffness. What should the nurse do first?
Correct Answer: A
Rationale: Sudden, severe headache and neck stiffness may indicate meningitis. A neurologic assessment and evaluation for meningeal irritation are critical. Blood pressure, glucose levels, and throat inspection are secondary.
Question 5 of 5
When assessing a patient's level of consciousness, which response would indicate a decreased level of consciousness?
Correct Answer: A
Rationale: A drowsy patient who can be easily aroused indicates a decreased level of consciousness. Alertness, quick responses, and full wakefulness are normal findings.
