DANB DANB Patient Medical History & Infection Risk Assessment

Question 1

Why is obtaining a thorough medical history essential from an infection control perspective?

Accepted Answer

It helps identify patients with conditions that may increase infection risk or require special precautions

Answer

A thorough medical history identifies patients with conditions such as immunosuppression, bloodborne infections, or antibiotic requirements that require modified infection control or treatment protocols.

Question 2

Under Standard Precautions, blood and body fluid precautions apply to:

Accepted Answer

All patients regardless of known or unknown infection status

Answer

Standard Precautions require treating all patients as potentially infectious regardless of their known diagnosis, because many infections are asymptomatic or undiagnosed.

Question 3

A patient with an active oral herpes (HSV) lesion presents for a routine cleaning. What is the appropriate infection control response?

Accepted Answer

Postpone elective procedures until the lesion resolves; if urgent, use additional barrier precautions

Elective dental procedures should be postponed when a patient has an active HSV lesion due to the high risk of transmission; urgent care should proceed with enhanced barrier precautions.

Question 4

Which of the following medical conditions requires an antibiotic prophylaxis consultation with the patient's physician before invasive dental procedures?

Accepted Answer

Certain cardiac conditions at risk for infective endocarditis

Answer

Patients with certain cardiac conditions (such as prosthetic heart valves or a history of infective endocarditis) may require antibiotic prophylaxis before invasive dental procedures per AHA guidelines.

Question 5

A hepatitis B surface antigen (HBsAg)-positive patient presents for dental treatment. The appropriate response is:

Accepted Answer
