Question number 4:


A client has a history of herpes simplex infection. As a nurse you know that the client is at risk of developing Bell’s palsy. Which of the following information should the nurse includes in giving the health teaching?

“To prevent Bell’s palsy, do facial exercises regularly”
“You should call the doctor if pain or herpes lesions occur near the ear”
“You should take antiviral agents to prevent development of Bell’s palsy”
“Medications to treat Bell’s palsy work only if started before paralysis onset.”

So lets go through these answer options one by one.
In option A. “To prevent Bell’s palsy, do facial exercises regularly” - Facial exercises do not prevent bells palsy.
In option B. “You should call the doctor if pain or herpes lesions occur near the ear.” Bells palsy us caused by a virus, such as the herpes simplex so this option is correct and they should call their doctor, because pain or herpes lesions near the ear may indicated the onset of Bell’s palsy.
In option C. “You should take antiviral agents to prevent development of Bell’s palsy”
Corticosteroids therapy not antivirals will be most effective in reducing the symptoms if started before paralysis is complete but will still be somewhat effective when started later.
And option D. “Medications to treat Bell’s palsy work only if started before paralysis onset.” This is not true… they are still effective if taken after the paralysis has already taken place.
Making the final & correct answer option B.
