The nurse educator is reviewing the process of pain transmission. Students should place these steps in which sequence?
 
  1. Substance P continues pain message.
 
  2. A and C fibers transmit the pain signal.
 
  3. Nociceptors are stimulated.
 
  4. Pain impulses reach the spinal cord.
 
  5. Pain impulses reach the brain.

Question 2

The physician orders pentoxifylline (Trental) for the patient with peripheral vascular disease. The nurse has completed medication education and determines that learning has occurred when the patient makes which statement(s)?
 
  1. It makes my red blood cells (RBCs) squishy so they can go into the little blood vessels.
  2. It decreases my platelets so my blood is less likely to clot.
  3. It decreases the stickiness of my blood.
  4. It changes how my liver makes clotting factors.
  5. It destroys clotting factors.

Answer to Question 1

3,2,4,1,5

Global Rationale: The order of pain transmission is stimulation of the nociceptors, transmission of pain signal by A and C fibers to the spinal cord, continuation of the pain message by substance P, and pain impulses reach the brain.

Answer to Question 2

1,2,3
Rationale 1: Pentoxifylline (Trental) acts on red blood cells (RBCs) to reduce their viscosity and increase their flexibility to allow them to enter partially occluded vessels.
Rationale 2: Pentoxifylline (Trental) also has antiplatelet action.
Rationale 3: Pentoxifylline (Trental) decreases the viscosity or stickiness of blood.
Rationale 4: Pentoxifylline (Trental) does not interfere with the manufacture of clotting factors in the liver.
Rationale 5: Pentoxifylline (Trental) does not destroy clotting factors.
Global Rationale: Pentoxifylline (Trental) acts on red blood cells (RBCs) to reduce their viscosity and increase their flexibility to allow them to enter partially occluded vessels. Pentoxifylline (Trental) also has antiplatelet action. Pentoxifylline (Trental) decreases the viscosity or stickiness of blood. Pentoxifylline (Trental) does not destroy clotting factors. Pentoxifylline (Trental) does not interfere with the manufacture of clotting factors in the liver.
