Which is considered the main relay station for sensory information related to pain?
 
  1. Cerebral cortex
   2. Limbic system
   3. Thalamus
   4. Reticular system

Question 2

The condition where serum sodium is below normal levels, resulting in fluid loss characterized by a proportionately greater loss of sodium than water, is:
 
  1. Isotonic dehydration.
   2. Hypotonic dehydration.
   3. Hydrostatic pressure.
   4. Osmotic pressure.

Answer to Question 1

3
Rationale:
1. The cerebral cortex is the second step in processing pain stimuli.
2. The transmission of pain moves through the limbic system after the thalamus.
3. The thalamus is the main relay station for sensory information. Pain information is then transmitted to the cerebral cortex as well as the reticular and limbic system for the processing and interpretation of pain.
4. Transmission of pain impulses occurs in the reticular system after traveling though the thalamus as the main relay station.

Answer to Question 2

2
Rationale:
1. This occurs when fluid loss is not balanced by intake, and the losses of water and sodium are in proportion.
2. This occurs when fluid loss is characterized by a proportionately greater loss of sodium than water. Serum sodium is below normal levels.
3. This occurs when extracellular fluid volume excess occurs; the increased fluid volume in the vascular compartment congests the veins.
4. This occurs when much of the osmotic pressure that pulls fluid into the capillaries is due to the presence of albumin and other plasma proteins made by the liver.
