Final answer:
Theophylline, used for chronic bronchitis, can become toxic if levels are too high, with symptoms including tremors. Fatigue is too general to be indicative, and bradycardia isn't common with Theophylline toxicity. Not everyone will experience side effects or toxicity.
Step-by-step explanation:
Theophylline is a bronchodilator used in the treatment of chronic bronchitis and other lung diseases. It relaxes and opens air passages in the lungs, improving breathing. However, like any medication, it can have side effects, and toxicity may occur if the levels in the body are too high.
The most common symptoms of Theophylline toxicity include restlessness, nausea, vomiting, dehydration, and most importantly, tremors. Therefore, the answer to the student's question would be B. Tremors. Gastrointestinal symptoms are also common with toxicity and could manifest as abdominal discomfort rather than constipation. Regarding the other options, fatigue is too general and could be present in numerous conditions, whereas bradycardia (slow heart rate) is not typically seen in Theophylline toxicity. Instead, tachycardia (rapid heart rate) is more common.
Keeping track of how the medication affects a patient, including any signs of potential toxicity, is crucial. Any indication of toxicity needs immediate medical attention. However, it's equally important to remember that not everyone will experience side effects or toxicity, and Theophylline can be a valuable part of managing chronic bronchitis.
