The nurse explains that Russell traction is a type of skin traction that:
 
  a. Subluxates the tibia
  b. Does not interfere with range of motion
  c. Prevents the knee from flexing
  d. Supplies continuous pull in two directions

Question 2

The brain is divided into two sections, called hemispheres. The hemispheres behave in a particular fashion in sending messages to the body. How do the hemispheres communicate information to the body?
 
  1. The hemispheres relay messages in a direct route.
   2. The hemispheres relay messages in a random fashion.
   3. The hemispheres relay messages in a contralateral fashion.
   4. The hemispheres relay messages in a unilateral route.

Answer to Question 1

D
Russell traction is skin traction (similar to Buck's traction) with a sling positioned under the knee, which prevents subluxation of the tibia. Although the traction interferes with full range of motion, the patient can change position without disrupting the continuous pull in two directions.

1. The hemispheres relay messages in a contralateral fashion.
2. The hemispheres relay messages in a contralateral fashion.
3. The hemispheres relay messages in a contralateral fashion. The right hemisphere sends messages to the left side of the body, and the left hemisphere sends messages to the right side of the body.
4. The hemispheres relay messages in a contralateral fashion.
