The client is 34 years old and has recently started taking theophylline.
The nurse knows that medication teaching has been successful when the client agrees to what activity?

Eating foods high in potassium.

Avoiding beverages that contain caffeine.

Taking the medication on an empty stomach.

Limiting fluid intake to 1,000 mL a day.

Answer and Explanation

The Correct Answer is B

Theophylline is a bronchodilator that is used to treat asthma and COPD.

It works by relaxing the smooth muscles of the airways and increasing airflow to the lungs.

However, theophylline has a narrow therapeutic range and can cause side effects such as nausea, vomiting, insomnia, tremors, and cardiac arrhythmias if the blood level is too high.

Caffeine is a stimulant that can increase the effects of theophylline and raise the risk of toxicity.

Therefore, patients taking theophylline should avoid caffeine-containing beverages such as coffee, tea, cola, and energy drinks.

Choice A is wrong because eating foods high in potassium has no effect on theophylline metabolism or action.

Potassium is an electrolyte that is important for nerve and muscle function, but it does not interact with theophylline.

Choice C is wrong because taking the medication on an empty stomach can increase the absorption of theophylline and cause gastric irritation.

Theophylline should be taken with food or milk to reduce stomach upset and prevent fluctuations in blood levels.

Choice D is wrong because limiting fluid intake to 1,000 mL a day can cause dehydration and increase the concentration of theophylline in the blood.

Choice C is wrong because teriparatide does not increase serum phosphorus, but decreases it.
