A nurse is reviewing a client's laboratory results before administering furosemide 40 mg IV bolus. For which of the following values should the nurse withhold the medication and contact the provider?

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:
BUN 15 mg/dL (blood urea nitrogen) is incorrect. An elevated BUN level can indicate kidney dysfunction or dehydration, but it's not typically associated with azathioprine's adverse effects. Azathioprine is known to affect bone marrow, leading to decreased blood cell counts, rather than directly impacting kidney function.
Choice B Reason:
WBC 3,000/mm³ (low white blood cell count) is correct. Azathioprine is an immunosuppressive medication used to treat various conditions, including rheumatoid arthritis. One of its known adverse effects is bone marrow suppression, which can lead to decreased production of blood cells, including white blood cells (WBCs). A low WBC count (leukopenia) can increase the risk of infections due to compromised immune function, making it an important adverse effect to monitor in individuals taking azathioprine.
Choice C Reason:
Hct 45% (hematocrit) is incorrect. A hematocrit of 45% is within the normal range for both men and women. Azathioprine adverse effects usually manifest as blood cell-related issues (such as leukopenia) rather than directly impacting hematocrit levels.
Choice D Reason:
Platelets 250,000/mm³: Platelets within the range of 150,000 to 400,000/mm³ are considered normal. Azathioprine typically affects white blood cells more prominently than platelet counts.
