A client receiving TPN requires monitoring for which potential complication?

Monitoring for electrolyte imbalance is crucial for a client receiving total parenteral nutrition (TPN) due to the composition of TPN solutions, which can significantly affect the body’s electrolyte levels. TPN solutions typically contain various concentrations of electrolytes such as sodium, potassium, magnesium, calcium, and phosphorus. If these electrolytes are not adequately monitored and adjusted, the client is at risk of developing imbalances, which can lead to serious complications such as cardiac arrhythmias, muscle weakness, and neurological issues.

While excessive weight loss, medication interactions, and infection risk are valid concerns in patients receiving TPN, electrolyte imbalances are more directly associated with the administration of TPN due to the potential for rapid shifts in electrolyte levels. Consequently, vigilant monitoring of blood chemistries is essential to ensure the client's safety and to maintain homeostasis during TPN therapy.
