What is the recommended action if a patient with preeclampsia has a urine output of less than 30 mL/hr?

In the context of managing a patient with preeclampsia, a urine output of less than 30 mL/hr is a critical sign that may indicate worsening renal function, fluid overload, or other complications. This low output is a serious concern, as it can reflect the severity of the patient's condition and the potential for progression to more severe forms of preeclampsia or even eclampsia.

Alerting the physician is essential because they may need to evaluate the patient promptly, adjust the management plan, and potentially initiate interventions that could be life-saving for both the mother and fetus. The physician can determine whether further diagnostics, medications, or possible delivery is necessary based on a comprehensive assessment of the patient’s status.

The other options, while potentially relevant in different scenarios, do not address the immediate need for medical oversight. Increasing intravenous fluids could worsen fluid overload if the kidneys are not functioning adequately. Checking blood glucose levels does not directly relate to the assessment of renal function in this context. Administering diuretics without a physician's guidance could be harmful, especially in preeclampsia, which may complicate fluid balance and lead to further issues. Thus, notifying the physician is the appropriate and most critical action in this scenario
