A nurse is caring for a client who is taking lithium and reports starting a new exercise program. The nurse should assess the client for which of the following electrolyte imbalances?

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:
Increase in serum glucose is incorrect. Desmopressin, which is a synthetic form of vasopressin, primarily affects water reabsorption in the kidneys and doesn't directly impact glucose levels. Therefore, an increase in serum glucose wouldn't be an expected therapeutic response to desmopressin for diabetes insipidus.
Choice B Reason:
Decrease in blood pressure is incorrect. Desmopressin is primarily used for its antidiuretic effect, concentrating urine by increasing water reabsorption in the kidneys. It typically doesn't have a significant impact on blood pressure. Therefore, a decrease in blood pressure wouldn't typically be an anticipated therapeutic response to desmopressin in this context.
Choice C Reason:
Decrease in urine output is correct. Desmopressin is a synthetic form of vasopressin (antidiuretic hormone) used to treat diabetes insipidus, a condition characterized by excessive urination and extreme thirst due to the inability to concentrate urine. The primary goal of desmopressin is to reduce urine output by increasing water reabsorption in the kidneys, thereby decreasing excessive urination. Therefore, a decrease in urine output would indicate a therapeutic response to the medication in this context.
Choice D Reason:
Increase in WBC count is incorrect. Desmopressin's action is centered on affecting kidney function by regulating water reabsorption and does not involve changes in white blood cell count. Consequently, an increase in WBC count wouldn't be an expected therapeutic response to desmopressin for diabetes insipidus.
