Answer to Question 1
Correct Answer: 4
Rationale 1: Eating a larger meal in the evening usually causes sleeplessness.
Rationale 2: A MRI would not be ordered until other conditions were ruled out.
Rationale 3: Dieting can have an affect on sleep, but it would not be the best response in this case.
Rationale 4: Decreases in neurotransmitters signal the change from wakefulness to nonrapid eye movement (NREM) sleep. Late exercise increases adrenaline, and caffeine is a stimulant. Both of these factors could interrupt NREM sleep.

Answer to Question 2
Correct Answer: 4
Rationale 1: Increased levels of serotonin elevate mood, not energy levels.
Rationale 2: Though increased serotonin might improve sleep, there is no indication that increased serotonin reduces sleepwalking.
Rationale 3: SSRIs are serotonin reuptake inhibitors. Amphetamines, methylphenidate, and modafinil are stimulants.
Rationale 4: Cataplexy is a sudden loss of muscle strength manifesting as slurred speech, sagging of the jaw, head nodding, or even complete collapse of the body. Stimulants such as modafinil are not effective for cataplexy symptoms. Older therapies for cataplexy include antidepressants, such as TCAs or SSRIs.
