Feedback:
Answer A. Therapeutic theophylline levels should be
between 10 and 20 mcg/mL. A level between 0.5 and 5
mcg/mL would be low and would not produce a therapeutic
effect. Levels between 25 and 50 mcg/mL would be too high
and could cause serious adverse effects.

Question 3
2 out of 2 points
The nurse is caring for a patient who is receiving
intravenous
theophylline. The patient complains of headache and nausea.
The nurse will contact the provider to
Answer
s: a.
change the medication to an oral
theophylline.
b.
suggest an alternative methylxanthine
medication.
c.
obtain an order for a serum
theophylline level.
d.
request an order for an analgesic
medication.
Response
Feedback Answer C. Theophylline has a narrow therapeutic index and a
: risk for severe symptoms with toxic levels. When patients report
symptoms of theophylline adverse effects, a serum drug level
should be obtained. Giving an oral theophylline would only
compound the problem if the patient has a toxic drug level.
Analgesics may be used, but only after toxicity is ruled out.
Adding a different methylxanthine will compound the symptoms
and will likely result in drug interaction or unwanted synergism.
