A client diagnosed with narcolepsy, sleepwalking, and cataplexy is prescribed a selective serotonin reuptake inhibitor (SSRI). Which explanation regarding this medication is the most accurate?
1. It lowers levels of serotonin, thereby increasing serotonin and elevating energy levels.
2. It helps with sleepwalking because the increase in serotonin allows the client a deeper sleep.
3. It decreased sleepiness, as SSRIs are stimulants, which will help the client maintain wakefulness.
4. It decreased episodes of slurred speech, sagging of the jaw, and head nodding.
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.
