Neurological Assessment NCLEX Questions Questions
Question 1 of 5
A pool of presynaptic neurons innervate the dendrites of a postsynaptic neuron. Electrical signals are transferred from the dendrites to the soma of the postsynaptic neuron by which process?
Correct Answer: D
Rationale: Electrotonic conduction transfers signals in dendrites, which lack sufficient voltage-gated channels for action potentials. TMP13 pp. 590-591
Question 2 of 5
The sensation of temperature is signaled mainly by warm and cold receptors whose sensory fibers travel in association with the sensory fibers carrying pain signals. Which statement best characterizes the transmission of signals from warm receptors?
Correct Answer: B
Rationale: Warm receptor signals travel via slow-conducting type C fibers. TMP13 p. 630
Question 3 of 5
An 85-year-old woman visits the ophthalmologist because of difficulty seeing. The patient is given an eye examination, and bifocal lenses are prescribed. The physician notes that the lenses of her eyes are clear. The woman sees well with her new prescription glasses. Which of the following best describes the most likely vision problem in this woman?
Correct Answer: D
Rationale: Presbyopia, loss of lens elasticity with age, requires bifocals for near/far vision. TMP13 p. 640
Question 4 of 5
Which of the following best describes the electrical response of the rods to light?
Correct Answer: D
Rationale: Light causes rod hyperpolarization by closing sodium channels. TMP13 p. 651
Question 5 of 5
Which sensory system has the smallest range of intensity discrimination?
Correct Answer: C
Rationale: Olfaction has a narrow intensity range (10-50 times threshold) compared to other systems. TMP13 p. 690
