Question 1

A patient taking warfarin should NOT receive which pain medication without physician consultation?

Accepted Answer

Aspirin

Answer

Aspirin has antiplatelet properties that enhance warfarin's anticoagulant effect, significantly increasing the risk of excessive bleeding.

Question 2

Which medication is the drug of choice for treating anaphylaxis in the dental office?

Accepted Answer

Epinephrine 1:1,000

Answer

Epinephrine 1:1,000 is the first-line treatment for anaphylaxis because it rapidly constricts blood vessels, reverses bronchospasm, and counteracts the life-threatening allergic response.

Question 3

What is the maximum recommended daily dose of acetaminophen for a healthy adult?

Accepted Answer

4,000 mg

Answer

The maximum recommended dose of acetaminophen for adults is 4,000 mg per day; exceeding this limit poses a risk of serious hepatotoxicity.

Question 4

Which drug is used during a dental emergency to relieve chest pain caused by angina?

Accepted Answer

Nitroglycerin

Answer

Nitroglycerin is a coronary vasodilator used sublingually to relieve angina by increasing blood flow to the heart muscle.

Question 5

Patients taking monoamine oxidase inhibitors (MAOIs) should avoid which component of local anesthetic solutions?

Accepted Answer

All vasoconstrictors

Answer

MAOIs inhibit the breakdown of catecholamines, so combining them with any vasoconstrictor (epinephrine, levonordefrin) can precipitate a dangerous hypertensive crisis.
