What are the signs of hypoglycemia in a dental patient and how should the nurse respond?

• A. High blood sugar symptoms
• B. Nausea only
• C. Sudden sweating, tremor, hunger, dizziness, and pallor
• D. Dizziness only

Answer: (C)

Recognising hypoglycemia relies on the classic autonomic warning signs that appear when blood glucose falls: sudden sweating, tremor, hunger, dizziness and pallor. In a dental patient these signs are a red flag that help you act quickly before confusion or loss of consciousness develops.

The best response is to stop any procedure if needed and assess the patient's awareness and ability to swallow. If they are conscious and able to swallow, give fast-acting carbohydrates right away—such as a glucose gel, glucose tablet, or a sugary drink—about 15-20 grams. After about 10 to 15 minutes, reassess symptoms and, if necessary, provide another 15-20 grams. If the patient’s symptoms improve, offer a small snack and ensure they are accompanied home or monitored until stable.

If the patient is unconscious or cannot swallow, do not give anything by mouth. Call emergency services immediately and follow local protocol—position the patient safely, monitor airway and breathing, and administer glucose by trained staff if available (such as a glucagon kit) according to the clinic’s emergency protocol. Once stabilized, document the episode and review the patient’s diabetes plan with the team.

Why this fits: those signs specifically point to hypoglycemia rather than hyperglycemia or nonspecific symptoms. Other options describe high blood sugar or vague symptoms that don’t match the acute warning signs of a hypoglycemic event.
