A patient states that many of his friends told him to ask for Valium or Ativan to help him sleep while hospitalized. The nurse knows that nonbenzodiazepines (such as Ambien) are often preferred over benzodiazepines (Ativan or Valium). Why is this?
1) Benzodiazepines are eliminated from the body faster than are nonbenzodiazepines, so they do not provide a full night of sleep. 2) Nonbenzodiazepines cause daytime sleepiness, allowing people to rest throughout the day. 3) Benzodiazepines produce daytime sleepiness and alter the sleep cycle. 4) Nonbenzodiazepines linger in the body longer than do benzodiazepines.
