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?

A. "You should take this medication on an empty stomach:"
Bumetanide can be taken with or without food. It is not necessary to take it on an empty stomach.
B. "You should monitor for hearing difficulties:"
This is the correct answer. Loop diuretics, including bumetanide, are associated with ototoxicity, which can lead to hearing difficulties or hearing loss. Clients should be instructed to report any changes in hearing.
C. "You should decrease your intake of foods high in potassium:"
Bumetanide can cause potassium loss, but instructing the client to decrease potassium intake may not be appropriate without knowing the client's specific potassium levels. Monitoring potassium levels and adjusting the diet or prescribing supplements as needed would be a more individualized approach.
D. "You should take the medication at bedtime:"
Bumetanide is often prescribed in the morning to avoid disrupting sleep with increased urination during the night. Taking it at bedtime is not a typical recommendation.

A. Acetaminophen: This is a common pain reliever and fever reducer. Acetaminophen is often used alongside other medications, including opioids like morphine, to manage pain more effectively. It's typically safe to use with morphine and is not an immediate concern for clarification.

B. Insulin glargine: Insulin glargine is a long-acting insulin used to control blood sugar levels in individuals with diabetes. While it's important to monitor blood sugar levels in patients receiving opioids, especially if they have diabetes, insulin glargine itself doesn't directly interact with morphine or the PCA pump.

C. Ondansetron: Ondansetron is an anti-nausea medication commonly used to prevent nausea and vomiting, particularly associated with chemotherapy or surgery. Patients receiving morphine, especially those with cancer, may also be prone to nausea. Ondansetron helps manage this side effect and does not typically interact adversely with morphine.

D. Naloxone: Naloxone is an opioid antagonist used to rapidly reverse the effects of opioid overdose, including respiratory depression, caused by drugs like morphine. It's administered in emergency situations to counteract the potentially life-threatening effects of opioids. While naloxone is critical for opioid safety, its presence on the medication list requires clear understanding and specific instructions regarding its use, dosage, and administration protocols in case of opioid-related emergencies.
