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. 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.

A. Infiltration:
Infiltration refers to the inadvertent administration of a non-vesicant solution into the surrounding tissue. It is characterized by swelling, pallor, and coolness at the infusion site, but redness and inflammation along the vein are not typical signs of infiltration.
B. Extravasation:
Extravasation occurs when a vesicant solution (a substance that can cause tissue damage) infiltrates into the surrounding tissue. It can cause tissue damage and necrosis. While inflammation is a concern with extravasation, it is not the primary sign, and redness may occur later.
C. Venous spasm:
Venous spasm involves the constriction of the blood vessel, leading to decreased blood flow. It is not typically associated with redness and inflammation along the vein.
D. Phlebitis:
This is the correct answer. Phlebitis refers to inflammation of a vein, and it is characterized by redness, warmth, and tenderness along the course of the vein. Phlebitis can be caused by various factors, including irritants in the infused solution, mechanical trauma, or infection.
