Final answer:
The most common and possibly devastating effect of peripheral total parenteral nutrition (PPN) is electrolyte imbalance, which can lead to serious health complications. For example, malnutrition can cause hypophosphatemia and hyperphosphatemia, disrupting normal bodily functions. It is crucial to closely monitor and manage electrolyte levels in PPN patients.
Step-by-step explanation:
The most common and possibly devastating effect of peripheral total parenteral nutrition (PPN) is electrolyte imbalance. When receiving PPN, patients may experience imbalances in important electrolytes such as sodium, potassium, and phosphate, which can have serious effects on the body. For example, malnutrition, which is a common cause of the need for PPN, can lead to hypophosphatemia (low phosphate levels) and hyperphosphatemia (high phosphate levels). Both conditions can disrupt normal bodily functions and negatively impact patient health. Overall, it is essential to closely monitor and manage electrolyte levels in patients receiving PPN to prevent complications and ensure optimal nutrition.
