Questions to Ask About Neurological System Questions
Question 1 of 5
The intracranial pressure is decreased by:
Correct Answer: D
Rationale: Intracranial pressure (ICP) can be reduced by intravenous mannitol (an osmotic diuretic), placing the patient in a head-up position (to improve venous drainage), and hyperventilation (which reduces CO2 levels and causes cerebral vasoconstriction). All these methods are clinically used to manage elevated ICP.
Question 2 of 5
Area(s) in the visual cortex involved in colour vision include:
Correct Answer: D
Rationale: Area V8, also known as the colour centre, is specifically involved in colour vision. V1, V2, and V3 are involved in early visual processing but not exclusively in colour vision.
Question 3 of 5
The following are true about spectral sensitivity of the retina:
Correct Answer: D
Rationale: Scotopic sensitivity peaks at 500 nm, photopic at 555 nm, and a yellow background shifts sensitivity to 440 nm for a 25-Hz stimulus. All statements are correct.
Question 4 of 5
The client newly diagnosed with multiple sclerosis (MS) states, 'I don't understand how I got multiple sclerosis. Is it genetic?' On which statement should the nurse base the response?
Correct Answer: A
Rationale: MS has a genetic component that increases susceptibility, but environmental factors, such as viral infections, also play a significant role in its development.
Question 5 of 5
The right hand of a client with multiple sclerosis trembles severely whenever she attempts a voluntary action. She spills her coffee twice at lunch and cannot get her dress fastened securely. Which is the best legal documentation in nurses' notes of the chart for this client assessment?
Correct Answer: D
Rationale: Documenting the specific circumstances under which the tremor worsens provides a clear and accurate description of the client's condition.
