Which result indicates that a client with polycystic kidney disease (PKD) is achieving treatment goals?

A blood pressure reading of 128/63 mmHg indicates that the client's hypertension is well managed, which is a primary treatment goal for patients with polycystic kidney disease (PKD). Effective management of blood pressure is crucial in PKD, as hypertension is a common complication and can accelerate kidney damage. Maintaining blood pressure within a normal range is essential for reducing the risk of cardiovascular events and preserving kidney function over time.

In contrast, the other options reflect values that may signal ongoing issues or complications associated with PKD. For example, a creatinine level of 2.3 mg/dL suggests impaired kidney function, which is not desirable in managing PKD. Proteinuria at 2+ indicates the presence of protein in the urine, a sign of kidney impairment and not an achievement of treatment goals. Lastly, a sodium level of 132 mEq/L indicates hyponatremia, which can lead to further complications and is not aligned with the treatment objectives.
