Which nursing assessment is most appropriate for a patient receiving continuous insulin therapy?

The most appropriate nursing assessment for a patient receiving continuous insulin therapy is regular blood glucose checks. This is crucial because insulin therapy is primarily utilized to manage blood glucose levels in patients with diabetes. Continuous insulin administration can significantly lower blood glucose, and this can lead to hypoglycemia if not monitored closely. Therefore, performing regular blood glucose checks allows healthcare providers to ensure that the patient's levels remain within a safe range, allowing for timely adjustments in insulin dosage as necessary.

Daily weight measurements can be important for monitoring fluid balance and nutritional status but are not as directly relevant to the immediate effects of insulin therapy. Blood pressure monitoring is generally important for overall health assessment but does not specifically relate to the effects of insulin. Monitoring serum calcium levels is typically relevant in other contexts, such as certain endocrine disorders or kidney function, rather than in the management of insulin therapy. Thus, regular blood glucose checks stand out as the essential assessment in this scenario.
