A nurse is providing teaching to a client about total parenteral nutrition (TPN). Which of the following information should the nurse include?

A. Seizures: Seizures are not an indication for potassium chloride administration. While severe electrolyte imbalances can contribute to seizures, potassium replacement is specifically indicated for low potassium levels rather than seizure management.

B. Kidney transplant: Kidney transplant patients may require careful electrolyte monitoring, but potassium chloride is not automatically indicated unless hypokalemia is present. Administration is based on lab values, not transplant status alone.

C. Arrhythmia: Hypokalemia can cause cardiac arrhythmias due to altered myocardial excitability. Potassium chloride is administered to correct low potassium levels and help prevent or treat arrhythmias.

D. Endocarditis: Endocarditis is an infection of the heart valves and is treated with antibiotics. Potassium chloride does not play a role in treating bacterial infections or inflammation of the heart.

A. Nitroglycerin: Nitroglycerin is a vasodilator used to treat angina and does not have known interactions with vancomycin. Concurrent use does not increase the risk of vancomycin toxicity or adverse effects.

B. Furosemide: Furosemide is a loop diuretic that can be nephrotoxic and ototoxic, similar to vancomycin. Using both medications concurrently increases the risk of kidney damage and hearing loss, requiring careful monitoring of renal function and auditory status.

C. Calcium chloride: Calcium chloride is used for hypocalcemia and cardiac stabilization but does not interact directly with vancomycin. No enhanced toxicity or adverse reaction is expected when these drugs are administered together.

D. Morphine: Morphine is an opioid analgesic with no direct interaction with vancomycin. While both drugs may depress the central nervous system in different ways, morphine does not increase the risk of vancomycin-related nephrotoxicity or ototoxicity.
