Answer to Question 1

ANS: A
A benzodiazepine (diazepam) is used to relive muscle spasm and spasticity.
Lorazepam's primary indication is as an antianxiety medication or to manage status epileptics.
Estazolam is used primarily to manage sleep disturbances.
Clonazepam is used primarily to manage panic disorders.

Answer to Question 2

ANS: B
The ability of benzodiazepines to depress central nervous system function is low. Because of their high lipid solubility, benzodiazepines readily cross the blood-brain barrier to reach sites in the central nervous system.
Benzodiazepines readily cross the blood-brain barrier.
Benzodiazepines are highly lipid soluble.
Benzodiazepines do not have more difficulty affecting the central nervous system than barbiturates do.
