Question 1

A patient with poorly controlled type 2 diabetes presents for dental anesthesia. Which blood glucose range is generally considered acceptable for proceeding with elective sedation?

Accepted Answer

70–180 mg/dL

Answer

A fasting blood glucose of 70–180 mg/dL is generally accepted as safe for elective dental procedures under sedation.

Question 2

Which systemic condition most significantly increases the risk of laryngospasm during dental sedation due to airway hyperreactivity?

Accepted Answer

Asthma

Answer

Asthma causes bronchial hyperreactivity, significantly raising the risk of laryngospasm and bronchospasm during sedation.

Question 3

A patient on warfarin for atrial fibrillation has an INR of 3.8 on the day of the procedure. What is the most appropriate action?

Accepted Answer

Postpone and consult with the patient's physician

Answer

An INR of 3.8 is supratherapeutic and poses significant bleeding risk; the procedure should be postponed pending physician guidance.

Question 4

During sedation, a patient with a known pheochromocytoma develops a sudden spike in blood pressure to 220/130 mmHg. Which drug is most appropriate for acute management?

Accepted Answer

Phentolamine IV

Answer

Phentolamine, an alpha-adrenergic blocker, is the drug of choice for hypertensive crises caused by catecholamine excess from pheochromocytoma.

Question 5

A patient with end-stage renal disease on hemodialysis is scheduled for sedation. Which opioid is MOST SAFELY used due to inactive metabolites?

Accepted Answer

Fentanyl

Answer

Fentanyl is preferred in renal failure because its metabolites are inactive and do not accumulate to cause toxicity.
