Answer to Question 1

D
Because of decreased liver size and function in older adults, the half-life of benzodiazepines is markedly lengthened. Benzodiazepines with long half-lives are unsuitable for older adults.

Answer to Question 2

A
Selective serotonin reuptake inhibitors (SSRIs) are approved for panic disorder and might be the most effective and safest agents for prophylaxis and long-term treatment. Benzodiazepines are effective during a panic attack but should not be used for long-term treatment because of the abuse and dependence potentials. It's important that the nurse show compassion for the patient's distress. Meditation may help overall, but not during panic attacks.
