Nociceptors differ from other nerve receptors in the body in that they: a. adapt very little to continual pain response. b. inhibit the infiltration of neutrophils and eosinophils. c. play no role in the inflammatory response. d. transmit only the thermal stimuli. ANS: A Nociceptors are stimulated by mechanical, chemical, or thermal stimuli. Nociceptors differ from other nerve receptors in the body in that they adapt very little to the pain response. The body continues to experience pain until the stimulus is discontinued or therapy is initiated. This is a protective mechanism so that the body tissues being damaged will be removed from harm. Nociceptors usually initiate inflammatory responses near injured capillaries. As such, the response promotes infiltration of injured tissues with neutrophils and eosinophils. DIF: Cognitive Level: Remember/Knowledge REF: p. 54 OBJ: Discuss the physiology of pain and anxiety. TOP:Nursing Process Step: Assessment MSC: NCLEX Client Needs Category: Physiological Integrity 2. A postsurgical patient is on a ventilator in the critical care unit. The patient has been tolerating the ventilator well and has not required any sedation. On assessment, the nurse notes the patient is tachycardic and hypertensive with an increased respiratory rate of 28 breaths/min. The patient has been suctioned recently via the endotracheal tube, and the airway is clear. The patient responds appropriately to the nurse’s commands. The nurse should: a. assess the patient’s level of pain. b. decrease the ventilator rate. c. provide sedation as ordered. d. suction the patient again. ANS: A Pulse, respirations, and blood pressure frequently result from activation of the sympathetic nervous system by the pain stimulus. Because the patient is postoperative, the patient should be assessed for the presence of pain and need for pain medication. Decreasing the ventilator rate will not help in this situation. Providing sedation may calm the patient but will not solve the problem if the physiological changes are from pain. The patient has just been suctioned and the airway is clear. There is no need to suction again. DIF: Cognitive Level: Analyze/Analysis REF: p. 55 OBJ: Describe the positive and negative effects of pain and anxiety in critically ill patients.
