BSL must be measured in patients with which of the following conditions?

Blood Glucose Level (BSL) measurement is a crucial step in assessing patients with certain conditions due to the potential impact of glucose levels on their overall health status. Patients with an altered conscious state, a history of diabetes, or those experiencing undifferentiated acute illness may have fluctuations in their blood glucose levels that need to be addressed.

When a patient presents with an altered conscious state, there is a significant concern for hypoglycemia (low blood sugar) or hyperglycemia (high blood sugar), especially in individuals with diabetes. Quick assessment of BSL helps determine if the altered consciousness is due to a glucose-related issue, allowing for timely intervention if needed.

For patients with a history of diabetes, regular monitoring of blood sugar levels is vital, especially when they present with symptoms of illness or altered consciousness. It aids in distinguishing between different causes of their symptoms and guides appropriate treatment.

In cases of medical patients with an undifferentiated acute illness, BSL measurement is equally important. These patients may present with a range of symptoms that do not clearly indicate a diagnosis, and glucose levels can provide critical insights into their metabolic state, helping triage and management decisions.

The other options do include various clinical scenarios that may require medical attention, but they
