A client is inquiring about sleep-related movement disorders. Which of the following conditions involves grinding of the teeth during sleep and is often associated with stress and anxiety?

Choice A rationale:

Restless legs syndrome (RLS). RLS is characterized by an irresistible urge to move the legs due to uncomfortable sensations. It is not associated with grinding of the teeth.

Choice B rationale:

Sleep-related rhythmic movement disorder (SRMD). SRMD involves repetitive and rhythmic movements during sleep, such as head banging or body rocking. It does not involve teeth grinding.

Choice C rationale:

Bruxism. This is the correct choice. Bruxism is the involuntary grinding or clenching of the teeth during sleep. It is often associated with stress, anxiety, and dental conditions. Treatment may involve the use of mouthguards to protect the teeth.

Choice D rationale:

Periodic limb movement disorder (PLMD). PLMD is characterized by repetitive limb movements during sleep, often involving the legs. It is not associated with teeth grinding.

Choice A rationale:

Excessive daytime sleepiness is a common consequence of insomnia. This question aims to assess whether the client experiences daytime impairment due to poor sleep initiation or maintenance. Inquiring about excessive daytime sleepiness is crucial because it reflects the potential impact of insomnia on the client's daily functioning.

Choice B rationale:

Asking about whether the client sleeps for more than 9 hours a night is not directly related to insomnia. While prolonged sleep can be seen in certain conditions like hypersomnolence, it doesn't address the core symptom of difficulty initiating or maintaining sleep associated with insomnia.

Choice C rationale:

Inquiring about abnormal respiratory patterns during sleep is relevant for sleep disorders like sleep apnea, which can cause disruptions in sleep due to breathing difficulties. However, this question is not specific to the symptoms of insomnia, which involve difficulties falling asleep or staying asleep.

Choice D rationale:

Asking about falling asleep at inappropriate times during the day is more aligned with narcolepsy, a disorder characterized by sudden and uncontrollable episodes of falling asleep. While some individuals with insomnia might experience daytime sleepiness, it's not a defining feature of the disorder.
