Neurological System Assessment Questions Questions
Question 1 of 5
A patient opens the eyes to painful stimuli, makes incomprehensible sounds, and withdraws from pain. What should the nurse calculate this patient's Glasgow Coma Scale score to be?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
Which of the following is not a target of a sympathetic preganglionic fiber?
Correct Answer: A
Rationale: The correct answer is A: intermural ganglion. Sympathetic preganglionic fibers innervate the chain ganglia, collateral ganglia, and adrenal gland, but not the intermural ganglia. Chain ganglia are located along the spinal cord, collateral ganglia are located outside the spinal cord, and the adrenal gland receives direct innervation from sympathetic preganglionic fibers. Intermural ganglia are not typically targeted by sympathetic preganglionic fibers in the autonomic nervous system.
Question 3 of 5
Which kind of drug would have anti-anxiety effects?
Correct Answer: D
Rationale: The correct answer is D: α-blocker. α-blockers work by blocking the α-adrenergic receptors, leading to vasodilation and decreased sympathetic activity, which helps reduce anxiety symptoms. Nicotinic agonists (A) and muscarinic agonists (C) do not directly affect anxiety levels. Anticholinergics (B) can actually worsen anxiety symptoms by blocking the parasympathetic nervous system. Therefore, α-blockers are the most suitable choice for producing anti-anxiety effects.
Question 4 of 5
Which of these is true of the Sabin but NOT the Salk polio vaccine?
Correct Answer: C
Rationale: The correct answer is C because the Sabin polio vaccine is an oral live attenuated vaccine that mimics the natural route of poliovirus infection, providing better immunity in the intestines. The Salk vaccine, on the other hand, is an inactivated vaccine given through injection. Choices A, B, and D are incorrect as the Sabin vaccine actually requires multiple doses, is not currently administered in the US, and is not an inactivated vaccine.
Question 5 of 5
A patient with a lack of oxygen to his heart will have pain in his chest and possibly in the shoulder, arms, or jaw. The nurse knows that the best explanation why this occurs is which one of these statements?
Correct Answer: C
Rationale: The correct answer is C because the sensory cortex does not have the ability to localize pain in the heart, leading to referred pain in other areas like the shoulder, arms, or jaw. This phenomenon is known as referred pain, where the brain misinterprets the source of pain. Choices A, B, and D are incorrect because the issue lies with the brain's interpretation of the pain location, not with sensory cortex discrimination, decreased oxygen supply to the affected areas, or lesions in the dorsal root. Therefore, C is the best explanation for why the patient experiences pain in the chest, shoulder, arms, or jaw when there is a lack of oxygen to the heart.
