How is the process of synaptic transmission best described?
 
  1. The conduction of action potentials that move rapidly from one neuron across the synapse to its target tissue
  2. When the nerve impulse reaches the terminal axon and enters the synaptic cleft
  3. The communication of the message from one cell to another utilizing neurotransmitters
  4. When a neurotransmitter is synthesized within a cell body, causing a contraction

Question 2

The client presents to the emergency department after a motor vehicle crash. Vital signs on admission are heart rate 56, respiratory rate 16, blood pressure 150/90, and temperature 97F.
 
  Which vital sign finding indicates a sympathetic nervous system response?
  1. Respiratory rate
  2. Temperature
  3. Blood pressure
  4. Heart rate

Answer to Question 1

Correct Answer: 3
Rationale 1: This is related, but it is an incomplete description of the process of synaptic transmission.
Rationale 2: This is related, but it is an incomplete description of the process of synaptic transmission.
Rationale 3: The communication of the message from one cell to another utilizing neurotransmitters is the best description of the process of synaptic transmission.
Rationale 4: This is related, but it is an incomplete description of the process of synaptic transmission.
Global Rationale: The communication of the message from one cell to another utilizing neurotransmitters is the best description of the process of synaptic transmission. All of the other choices are incomplete descriptions of the process of synaptic transmission.

Answer to Question 2

Correct Answer: 3
Rationale 1: A respiratory rate of 16 is within normal limits.
Rationale 2: A temperature of 97F is within normal limits.
Rationale 3: Elevated blood pressure is a response of the sympathetic nervous system's fight-or-flight response.
Rationale 4: The heart rate of 56, while decreased, is a response of the parasympathetic nervous system.
Global Rationale: Elevated blood pressure is a response of the sympathetic nervous system's fight-or-flight response. The respiratory rate and temperature are within normal limits. The heart rate of 56, while decreased, is a response of the parasympathetic nervous system.
