Question 1 of 5
Which of the following statements best describes substance P?
Correct Answer: D
Rationale: Substance P is a neurotransmitter found in the brain and the dorsal horn of the spinal column, not just in the brain. It is associated with pain transmission and modulation. Substance P is known to cause inflammation, edema, and pain. While it plays a role in pain perception, it does not decrease a client's sensitivity to pain (
Choice
A), nor are its levels typically drawn before administering narcotic analgesics (
Choice
B). Although substance P is involved in pain control, it is not responsible for managing depression (
Choice
C).
Therefore, the correct statement is that substance P is found in the dorsal horn of the spinal column.
