A client with a diagnosis of depression has been prescribed a medication that ultimately increases the levels of the neurotransmitter serotonin between neurons.
 
  Which of the following processes will accompany the actions of the neurotransmitter in a chemical synapse?
  A)
  Two-way communication between neurons is permitted in contrast to the one-way communication in electrical synapses.
  B)
  Communication between a neuron and the single neuron it is connected with will be facilitated.
  C)
  The neurotransmitter will cross gap junctions more readily.
  D)
  More neurotransmitters will cross the synaptic cleft and bond with postsynaptic receptors.

Question 2

A mother is placing her child into the bathtub. The child immediately jumps out of the tub and begins to cry, stating his feet are burning.
 
  The nurse in the emergency department knows that the child's response is based on which of the following pathophysiological principles listed below?
  A)
  Children react much quicker to contact with hot water than adults.
  B)
  The tactile sensation occurs well in advance of the burning sensation. The local withdrawal reflex reacts first.
  C)
  It takes a long time for thermal signals to be processed before the brain can send a signal through the spinal cord and tell the foot to withdraw.
  D)
  The thermal processing center is located on the rapid conducting anterolateral system on the same side of the brain as the injury.

Answer to Question 1

Ans:
D

Feedback:

In chemical synapses, neurotransmitters cross the synaptic cleft and bond with postsynaptic receptors to facilitate communication between neurons. This communication is one way, not two way, and each neuron has synaptic connections with thousands of other neurons. Gap junctions are associated with electrical synapses, not chemical synapses.

Answer to Question 2

Ans:
B

Feedback:

If a person places a foot in a tub of hot water, the tactile sensation occurs well in advance of the burning sensation. The foot has been removed from the hot water by the local withdrawal reflex well before the excessive heat is perceived by the forebrain. All other responses are incorrect.
