Which signs are commonly associated with hypoglycemia in a patient with diabetes?

• A. Slow pulse rate and low blood pressure
• B. Irritability, anxiety, confusion, and dizziness
• C. Flushing, anger, and forgetfulness
• D. Sleepiness, edema, and sluggishness

Answer: (B)

When blood glucose falls, the brain and autonomic nervous system respond in ways that produce both mood/mental changes and physical sensations. Irritability and anxiety arise from autonomic warning signals, while confusion and dizziness reflect the brain not getting enough glucose to function properly. This combination—irritability, anxiety, confusion, and dizziness—fits the pattern of hypoglycemia in a person with diabetes, because it covers both the nervous-system activation and the neuroglycopenic impact of low glucose.

Other options describe signs that aren’t typical for hypoglycemia. Slow pulse rate and low blood pressure aren’t the usual early responses and can point to other issues; flushing, anger, and forgetfulness aren’t the classic cluster seen with hypoglycemia; sleepiness with edema isn’t a characteristic pattern of low glucose.
