Which of the following nursing instructions is most helpful to a client experiencing mild seasonal affective disorder symptoms?
- A. Use sunglasses when exposed to sunlight.
- B. Install skylights.
- C. Sleep in a darkened room.
- D. Stay indoors during the winter time.
Correct Answer: B

The nurse has been working with a client who has difficulty controlling mood. The client continues to experience anger outbursts, which makes it difficult to maintain employment. When explaining this dysfunction to the client's family members, which area of the brain does the nurse identify as being the site for mood generation?
- A. The central nervous system
- B. The autonomic nervous system
- C. The limbic system
- D. The peripheral nervous system
Correct Answer: C
Rationale: The limbic system is responsible for mood generation, as it regulates emotions and related behaviors. The central nervous system includes the brain and spinal cord but is too broad to specifically address mood. The autonomic nervous system controls involuntary functions like heart rate, not mood. The peripheral nervous system handles sensory and motor functions outside the central nervous system.

- A. I have gained 25 lb in the last year.
- B. I feel that I am so sleepy all of the time.
- C. No one cares about me. I just want to die.
- D. I have a difficult time concentrating.

The nurse is completing a medication history for a client diagnosed with bipolar disorder. When assessing the medications, which medication classification is noted as an adjunct to lithium therapy?
- A. Antidiabetics
- B. Antihypertensives
- C. Anticonvulsants
- D. Antianginals
Correct Answer: C
Rationale: Anticonvulsant therapy may be co-prescribed for a brief period to sedate the client and relieve bizarre thought processes faster than monotherapy with lithium. Anticonvulsants enhance the action of gamma-aminobutyric acid (GABA) in much the same way that benzodiazepines reduce anxiety and they are believed to inhibit glutamate.
Anticonvulsants enhance which neurotransmitter in clients diagnosed with bipolar disorder?
- A. Serotonin
- B. Dopamine
- C. GABA
- D. Acetylcholine
Correct Answer: C
Rationale: Anticonvulsants may achieve their therapeutic effects by enhancing the action of GABA in much the same way that benzodiazepines reduce anxiety. Anticonvulsants do not enhance serotonin, dopamine, or acetylcholine.
