A. "I'll dial 911 if I still have pain after taking 3 nitroglycerin tablets 5 minutes apart.": While this reflects part of the correct sequence, waiting until all 3 doses are taken before seeking emergency help may delay life-saving treatment. Emergency services should be contacted sooner if the first dose is ineffective.
B. "I'll dial 911 if I still have pain after taking 4 nitroglycerin tablets over a 20-minute period.": This exceeds the recommended maximum of three sublingual nitroglycerin tablets within 15 minutes. Taking more than advised can increase the risk of hypotension and other complications.
C. "I'll dial 911 if 1 nitroglycerin tablet does not relieve my pain, and then take up to 2 more tablets 5 minutes apart while waiting.": This is the correct protocol. If chest pain persists after the first dose, the patient should immediately call 911 and may continue with up to two additional doses, each 5 minutes apart, while waiting for emergency responders.
D. "I'll dial 911 when I have pain and then take the nitroglycerin tablets.": Calling 911 immediately without trying the medication first may lead to unnecessary emergency activation. The recommended approach is to take the first dose, then call if pain persists after 5 minutes.

A. Avoid caffeine while taking this medication: Theophylline is a methylxanthine, similar in structure and effect to caffeine. Concurrent use can increase CNS stimulation and risk of side effects such as insomnia, tachycardia, and tremors. Avoiding caffeine helps prevent toxicity and unwanted stimulation.
B. Crush your extended-release tablet and mix it with apple sauce for easier consumption: Extended-release formulations should never be crushed, as this can lead to rapid absorption and potentially toxic drug levels. Theophylline has a narrow therapeutic index, and proper dosing is critical.
C. Take this medication as needed when you are not feeling well: Theophylline is a maintenance medication meant to be taken on a regular schedule. Taking it only as needed undermines its therapeutic effectiveness and can lead to inconsistent symptom control.
D. Consume a high-protein diet: While diet can influence drug metabolism, there is no routine recommendation for a high-protein diet with Theophylline. In fact, sudden dietary changes can alter its metabolism, requiring careful monitoring of serum drug levels.
