Pharmacological and Parenteral TherapiesQuestion 2306 of 2368

A client asks how a capsaicin cream applied to the skin helps relieve pain. What is the best response?

  1. It lowers fever and swelling by blocking prostaglandins.
  2. It constricts blood vessels so less blood reaches the area.
  3. It blocks the transmission of pain impulses from the skin.
  4. It acts in the spinal cord to stop release of neurotransmitters.
Show answer

Correct answer: It blocks the transmission of pain impulses from the skin.

Capsaicin applied to the skin blocks the transmission of pain impulses. Blocking prostaglandins is how NSAIDs work.
