A nurse is reviewing the medication administration record for a client who has cancer and is receiving morphine via a PCA pump. Which of the following prescriptions should the nurse clarify with the provider?

Choice A Reason:
"Limit your sodium intake." Is incorrect. Sodium restriction might be appropriate for some cardiovascular or renal conditions, but it is not specifically related to theophylline use.
Choice B Reason:
"Restrict milk products." is incorrect. Restricting milk products is not a necessary dietary consideration for theophylline. However, consuming high-fat dairy products may delay the absorption of theophylline, potentially affecting its effectiveness.
Choice C Reason:
"Avoid caffeinated beverages." Is correct. Theophylline is a bronchodilator used to treat respiratory conditions like asthma or chronic obstructive pulmonary disease (COPD). It belongs to the class of methylxanthine medications and acts similarly to caffeine. Consuming additional caffeine through beverages like coffee, tea, or certain sodas can increase the risk of adverse effects associated with theophylline, such as increased heart rate or nervousness. Hence, avoiding caffeinated beverages is advisable to minimize the risk of exacerbating these effects.
Choice D Reason:
"Take the medication with meals." Taking theophylline with or without meals is typically acceptable, but it's essential to maintain consistency in timing and avoid significant changes in dietary habits that might affect its absorption or metabolism.

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.
