When providing teaching for a patient who is prescribed a selective serotonin reuptake inhibitor (SSRI), which statement will the nurse include?
The SSRI will work faster than the older tricyclic antidepressants.
The SSRI will have an immediate beneficial effect on the patient’s depression symptoms.
The SSRI will not work well for severe cases of depression.

The SSRI may take several weeks to have a beneficial effect\
It may take several weeks to see the therapeutic effects of SSRIs.

Benzodiazepines (Zepam or Zolam)
A patient is prescribed an anorexiant. Which statement will the nurse include in patient teaching?
“Take the medication with your evening meal.”
“You will need to take this drug for at least 2 years.”
“If you develop a dry mouth, stop taking the drug immediately.”
“Avoid intake of caffeine.”
“Avoid intake of caffeine.”
Caffeine in any form must be avoided by patients taking anorexiants. These medications should be taken in the morning to prevent interference with sleep. The drugs are taken on a short-term basis. Dry mouth frequently develops and can be managed by sucking ice chips and keeping a bottle of water nearby at all times. These drugs should not be abruptly stopped as a rebound increase of appetite may develop.
Cause sleep, much more potent effect on CNS than sedatives
