A nurse is providing discharge dietary teaching to a client who has a new prescription for theophylline. Which of the following instructions should the nurse include?

Choice A Reason:
Meloxicam is incorrect. Meloxicam is a nonsteroidal anti-inflammatory drug (NSAID) used primarily for managing mild to moderate pain and inflammation. While it can provide relief for mild pain, it may not be potent enough to effectively manage severe pain, especially in cases of advanced cancer-related pain, where stronger analgesics are often necessary.
Choice B Reason:
Aspirin is incorrect. Aspirin, like meloxicam, is an NSAID used for mild to moderate pain relief and has anti-inflammatory properties. While it can be effective for certain types of pain, it's generally not the first choice for severe pain management, particularly in cases of advanced cancer-related pain where stronger opioids are typically required for adequate relief.
Choice C Reason:
Hydromorphone is correct. Hydromorphone is a potent opioid analgesic used to manage severe pain, especially in cancer-related pain or post-operative settings. In cases of severe pain, opioids like hydromorphone are commonly utilized due to their effectiveness in providing relief.
Choice D Reason:
Caldofor is incorrect. The term "Caldofor" does not appear to correspond to any recognized medication commonly used for pain relief. It's possible that this might be a misspelling or an unfamiliar or less common drug name. Without a specific drug identification, it's challenging to assess its suitability or effectiveness for managing severe pain associated with pancreatic cancer.

Choice A Reason:
Nausea is incorrect. Nausea is a common side effect of many medications, including antibiotics like amoxicillin. While it can be a side effect of an allergic reaction, it's also a general symptom that can occur due to various reasons, such as gastrointestinal upset or the direct effects of the antibiotic on the stomach lining. Nausea alone is less specific for indicating an allergic reaction compared to severe symptoms like laryngeal edema.
Choice B Reason:
Insomnia is incorrect. Insomnia, or difficulty sleeping, is not a typical manifestation of an allergic reaction to amoxicillin. Allergic reactions usually involve more immediate and visible symptoms such as skin rash, itching, swelling, difficulty breathing, or in severe cases, anaphylaxis. Insomnia is not a common symptom associated with allergic responses to antibiotics.
Choice C Reason:
Laryngeal edema is correct. Laryngeal edema, or swelling of the larynx, is a serious symptom of an allergic reaction known as anaphylaxis. This severe allergic reaction can be life-threatening due to its potential to obstruct the airway, leading to breathing difficulties.
Choice D Reason:
Cardiac dysrhythmia is incorrect. While medications can sometimes affect heart rhythms, cardiac dysrhythmia is not a common symptom of an allergic reaction to amoxicillin. Allergic reactions tend to manifest with more immediate symptoms like skin reactions, respiratory issues, or swelling rather than primarily affecting the heart rhythm.
