The autonomic nervous system includes any of the following EXCEPT:

Which treatment modality should a nurse recommend to help a patient diagnosed with somatic symptom disorder cope more effectively?
- A. Flooding
- B. Relaxation
- C. Response prevention
- D. Systematic desensitization
Correct Answer: B
Rationale: The correct answer is B: Relaxation. For a patient with somatic symptom disorder, relaxation techniques can help reduce anxiety and physical symptoms associated with the disorder. Relaxation promotes a sense of calm, reduces stress, and can improve coping skills. Flooding (A) involves exposing a patient to a feared stimulus in a sudden and intense manner, which can exacerbate symptoms in somatic symptom disorder. Response prevention (C) is used in treating obsessive-compulsive disorder, not somatic symptom disorder. Systematic desensitization (D) is a technique used for phobias, not somatic symptom disorder.
Acetylcholine is a neurotransmitter that provides for communication between muscles and nerves. When there is a problem with the interaction between acetylcholine and the acetylcholine receptor sites on the muscles, which condition(s) can occur?
- A. Myasthenia gravis
- B. Botulism
- C. Multiple sclerosis
- D. A and B
Correct Answer: D
Rationale: Myasthenia gravis and botulism are conditions that result from impaired acetylcholine function. Myasthenia gravis is an autoimmune disorder that blocks acetylcholine receptors, while botulism prevents acetylcholine release. Multiple sclerosis affects the myelin sheath, not acetylcholine. Understanding these conditions highlights the importance of acetylcholine in neuromuscular communication.
