What is a crucial parameter for the home care nurse to monitor during visits with a client on parenteral nutrition?

Monitoring glucose levels is crucial for a home care nurse visiting a client on parenteral nutrition because these patients are at risk for hyperglycemia or hypoglycemia due to the high concentrations of carbohydrates in their nutritional formulas. Parenteral nutrition involves the intravenous administration of nutrition, which typically includes glucose, amino acids, lipids, minerals, and vitamins. Since this route bypasses the normal digestive system, patients may not have the same regulatory controls over glucose metabolism as those who eat normally.

Elevated glucose levels can lead to complications such as osmotic diuresis, dehydration, and increased risk of infection, while low glucose levels can result in hypoglycemic symptoms such as confusion, sweating, and even loss of consciousness. Regular monitoring helps to ensure that glucose levels are maintained within a safe range and allows for timely interventions should levels become abnormal.

While weight, temperature, and blood pressure are all important parameters in the overall assessment of a patient’s health, glucose levels take precedence in the context of parenteral nutrition due to the direct impact on the patient's metabolic state and the potential for acute complications.
