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.
The Correct Answer is B
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.

Correct Answer is A
Explanation
The nurse should ask this question because the client is taking a chemical stimulant laxative, which can cause dehydration and electrolyte imbalance, especially in combination with medications for heart failure and osteoarthritis that may also affect fluid and electrolyte balance. The nurse should assess the client’s hydration status and risk of hypovolemia or hypotension.
Choice B. Timing of medication administration is wrong because it is not the priority question in this situation.
The nurse should ask this question later to determine if the client is taking the medications as prescribed and if there are any drug interactions or adverse effects.
Choice C. Previous effectiveness of laxatives is wrong because it is not relevant to the client’s current condition.
The nurse should ask this question later to evaluate the client’s bowel habits and history of constipation.
Choice D. The amount of fiber intake is wrong because it is not the priority question in this situation.
The nurse should ask this question later to educate the client about dietary measures to prevent constipation and promote bowel health.
Correct Answer is B
Explanation
Metoclopramide is a medication that increases muscle contractions in the upper digestive tract and speeds up the rate at which the stomach empties into the intestines. It is used to treat gastroparesis (slow stomach emptying) in people with diabetes, which can cause heartburn and stomach discomfort after meals.
Choice A is wrong because impaction is a condition where a large mass of dry, hard stool becomes stuck in the rectum and cannot be passed.
Metoclopramide does not treat impaction, but laxatives or enemas may be used instead.
Choice C is wrong because encopresis is a condition where a child over the age of 4 has involuntary bowel movements, usually due to chronic constipation.
Metoclopramide does not treat encopresis, but behavioral therapy, laxatives, or dietary changes may be used instead.
Choice D is wrong because metoclopramide is not used for clients requiring diagnostic procedures involving the stomach or intestines.
However, it may be used to prevent nausea and vomiting caused by chemotherapy or surgery.
