Question 1 of 1
1. Question
A client has begun therapy with theophylline (Theo-24). A nurse plans to teach the client to limit the intake of which of the following while taking this medication?
Correct
Answer & Rationale:
Option 1 is Correct
Rationale: Theophylline (Theo-24) is a methylxanthine bronchodilator. The nurse teaches the client to limit the intake of xanthine-containing foods while taking this medication. These foods include coffee, cola, and chocolate.
Test-Taking Strategy: Use the process of elimination. Recall that theophylline is a xanthine bronchodilator and that intake of excessive amounts of foods naturally high in xanthines should be curtailed. Also recalling that these medications cause cardiac and central nervous system stimulation will direct you to option 1. Review the foods naturally high in xanthines if you had difficulty with this question.
