NURS 83PL Study Guide - Quiz Guide: Opioid Antagonist, Dextropropoxyphene, Methadone
Document Summary
The nursing instructor teaches the nursing students about neural mechanisms of pain. Substance p modifies sensory information in the spinal cord. Substance p is also known as an endogenous opioid. Substance p stimulates pain receptors in the spinal cord. Substance p controls which pain signals reach the brain: a patient, addicted to heroin, is being treated for opioid dependence. The patient asks how this will help because methadone (dolophine) is another opioid. "methadone (dolophine) will make you really sick if you use heroin. " "methadone (dolophine) does not cause euphoria like heroin does. " "methadone (dolophine) causes you to have an allergy to heroin. : a nurse is providing community education on the increase in heroin use. Heroin is not as dangerous as oxycodone: the patient has a patient-controlled analgesia (pca) pump following surgery. The nurse keeps naloxone (narcan) in the patient"s room as per protocol. Naloxone (narcan) enhances the effect of the opioid in the patient-controlled analgesia (pca) pump and increases analgesia.
