A patient with insulin dependency is moving to a high-altitude area to exercise. What must the patient know about glycemic control at high altitudes?

The selection that glucose monitors have problems with reliability at high altitude is correct because the atmospheric pressure and oxygen levels at high altitudes can impact the performance of some glucose monitoring devices. Certain types of glucose monitors may experience interference due to changes in the surrounding environment, which could lead to inaccurate readings. This is particularly crucial for individuals with insulin dependency, as they rely heavily on accurate monitoring to manage their blood glucose levels effectively and avoid complications.

Understanding the challenges with glucose monitoring at high altitudes can help patients take appropriate measures, such as being extra vigilant about checking their levels under various conditions and possibly adopting alternative monitoring strategies when necessary. This awareness can lead to better glycemic control and adjustments in insulin administration when required.
