Certified Emergency Nurse (CEN) Practice Test

Question: 1 / 400

Which of the following is a symptom of mild hypoglycemia?

Severe confusion

Seizures

Tachycardia and sweating

Mild hypoglycemia typically presents with symptoms that are the body’s response to low blood sugar levels. Tachycardia, which is an increased heart rate, and sweating are both part of the adrenergic response caused by the release of catecholamines when blood sugar is low. These symptoms serve as warning signals indicating that glucose levels are dropping and the body needs to take action, such as ingesting fast-acting carbohydrates.

In contrast, severe confusion, seizures, and coma are symptoms often associated with more profound hypoglycemia, reflecting a significant decrease in brain glucose availability and requiring immediate medical intervention. These more serious symptoms do not manifest in mild cases and indicate a greater severity of hypoglycemia that goes beyond the symptoms typically experienced when blood glucose levels are slightly low.
