The patient receives morphine for pain. He asks the nurse how it works to relieve pain. What is the best response by the nurse?
 
  1. It inhibits the primary pain neurotransmitters in your brain.
  2. It stimulates the receptors that secrete endorphins in your brain.
  3. It stimulates a receptor in your brain that induces pleasure.
  4. It promotes the primary pleasure neurotransmitters in your brain.

Question 2

The patient has intractable pain, and the physician has proposed a nerve block. The nurse plans to teach the patient about nerve blocks. Which statement would be included in the best plan of the nurse?
 
  1. A nerve block depresses the activity of the sympathetic nervous system.
  2. A nerve block enhances the effect of most of the endogenous opioids.
  3. A nerve block modifies sensory information being sent to the spinal cord.
  4. A nerve block stops pain transmission along the nerve to stop the pain.

Answer to Question 1

Correct Answer: 3
Rationale: Opioids exert their actions by interacting with the mu and kappa receptors in the brain. Drugs that stimulate these receptors are opioid agonists. Opioids do not promote release of the pleasurable neurotransmitters. Opioids do not promote secretion of endorphins. Opioids do not inhibit neurotransmitters responsible for pain.

Answer to Question 2

Correct Answer: 4
Rationale: Nerve blocks are accomplished by injection of alcohol or another neurotoxic substance into neurons. This blocks nerve transmission and has the potential to provide total pain relief. A nerve block does not enhance the effect of endogenous opioids. A nerve block does not modify sensory information sent to the spinal cord. A nerve block does not depress the activity of the sympathetic nervous system.

Both answers were spot on, thank you once again
