Which assessment finding is reflective of the parasympathetic nervous system?

1. Frequent bowel movements
2. Elevated liver enzymes
3. Pupils 8 mm and equal
4. Decreased urine output

Question 2

Which statement explains how autonomic drugs affect synaptic transmission?

1. Drugs are frequently given to correct autonomic dysfunction.
2. Drugs used to prevent the normal destruction of the neurotransmitter cause the neurotransmitter to remain in the synapse for a longer period of time.
3. Drugs influence the release of neurotransmitters at the postganglionic site.
4. Drugs that decrease the degree of neurotransmitter synthesis stimulate autonomic responses.

Answer to Question 1

Correct Answer: 1
Rationale 1: Increased peristalsis causing frequent bowel movements is a response of the parasympathetic nervous system.
Rationale 2: Elevated liver enzymes are a sympathetic nervous system response.
Rationale 3: Pupils 8 mm and equal is a sympathetic nervous system response.
Rationale 4: A decrease in urine output is a sympathetic nervous system response.
Global Rationale: Increased peristalsis causing frequent bowel movements is a response of the parasympathetic nervous system. Elevated liver enzymes, pupils 8 mm and equal, and a decrease in urine output are all sympathetic nervous system responses.

Answer to Question 2

Correct Answer: 2
Rationale 1: This is not true; most drugs are used to treat disorders of target organs.
Rationale 2: This is true; these drugs stimulate autonomic responses.
Rationale 3: This is not true; drugs influencing the release of neurotransmitters occurs at the preganglionic site.
Rationale 4: This is not true; drugs that decrease the degree of neurotransmitter synthesis inhibit autonomic responses.
Global Rationale: Drugs used to prevent the normal destruction of the neurotransmitter cause the neurotransmitter to remain in the synapse for a longer period of time is a true statement. The other statements are all false.
