NURS 611 EXAM 2 Questions with Answers Provided Test Prep Chapter 16: Pain, Temperature Regulation, Sleep, and Sensory Function MULTIPLE CHOICE 1. Pricking one’s finger with a needle would cause... minimal pain, whereas experiencing abdominal surgery would produce more pain. This distinction is an example of which pain theory? a. Gate control theory c. Specificity theory b. Intensity theory d. Pattern theory ANS: C According to the specificity theory, a direct relationship exists between the intensity of pain and the extent of tissue injury. The remaining options are not related to the intensity of perceived pain. PTS: 1 REF: Page 485 2. Which pain theory proposes that a balance of impulses conducted from the spinal cord to the higher centers in the central nervous system (CNS) modulates the transmission of pain? a. GCT c. Specificity theory b. Pattern theory d. Neuromatrix theory ANS: A Only the gate control theory (GCT) explains that a balance of impulses conducted to the spinal cord, where cells in the substantia gelatinosa function as a spinal gate, regulates pain transmission to higher centers in the CNS. PTS: 1 REF: Page 485 6. Which spinal tract carries the most nociceptive information? a. Archeospinothalamic c. Dorsal spinothalamic b. Paleospinothalamic d. Lateral spinothalamic ANS: D Most nociceptive information travels by means of ascending columns in the lateral spinothalamic tract (also called the anterolateral funiculus). The other tract options do not carry the most nociceptive information. PTS: 1 REF: Page 487 7. The major relay station of sensory information is located in the: a. Basal ganglia c. Thalamus b. Midbrain d. Hypothalamus ANS: C Although the organization of all of the ascending tracts is complex, the principal target for nociceptive afferents is the thalamus, which, in general, is the major relay station of sensory information. The remaining options do not fulfill this objective. PTS: 1 REF: Page 487 8. Where in the CNS does a person’s learned pain response occur? a. Cerebral cortex c. Thalamus b. Frontal lobe d. Limbic system ANS: A The cognitive-evaluative system overlies the individual’s learned behavior concerning the experience of pain and can modulate the perception of pain and is mediated only through the cerebral cortex. PTS: 1 REF: Page 487 10. What part of the brain provides the emotional response to pain? a. Limbic system c. Thalamus b. Parietal lobe d. Hypothalamus ANS: A The limbic and reticular tracts are involved in alerting the body to danger, initiating arousal of the organism, and emotionally processing the perceived afferent signals, not just as stimuli, but also as pain. The remaining options do not fulfill this objective. PTS: 1 REF: Page 487 [Show More]
