DRC Patient Management & Special Populations 2

Question 1

At what age or developmental stage is it typically recommended to begin taking bitewing radiographs for a pediatric patient?

Accepted Answer

When proximal surfaces of primary posterior teeth can no longer be visually examined (approximately age 3–5)

Answer

When the first primary tooth erupts

Answer

Only after all permanent teeth have erupted

Answer

When the patient is old enough to cooperate fully, typically age 10

Question 2

A patient with a latex allergy presents for a radiographic examination. The MOST important consideration is:

Accepted Answer

Ensuring all gloves, barriers, and equipment covers are latex-free

Answer

Using only digital sensors to avoid chemical exposure from film processing

Answer

Scheduling the appointment at the end of the day to minimize cross-contamination

Answer

Reducing radiation exposure to minimize physiologic stress on an already compromised immune system

Question 3

Regarding dental radiographs for a patient with a cardiac pacemaker, which statement is MOST accurate?

Accepted Answer

Modern pacemakers are well-shielded and dental X-ray units do not significantly interfere with their function

Answer

Dental radiographs are absolutely contraindicated for all pacemaker patients

Answer

Exposure time must be reduced by half to prevent electromagnetic interference

Answer

Only panoramic radiographs are safe for pacemaker patients

Question 4

For a patient who is HIV positive, which radiation protection and infection control protocol is MOST appropriate?

Accepted Answer

Apply standard precautions identical to those used for all other patients

Answer

Use double lead aprons to provide additional whole-body protection

Answer

Limit radiographic exposure to bitewing radiographs only

Answer

Sterilize sensors with chemical immersion rather than heat after each use

Question 5

An 8-year-old child in the mixed dentition stage requires posterior periapical radiographs. Which receptor size is MOST appropriate?

Accepted Answer

Size 1

Answer

Size 0

Answer

Size 2

Answer

Size 4

Question 6

A patient reports that they are taking warfarin (an anticoagulant). Which radiographic consideration is MOST relevant?

Accepted Answer

No specific radiographic modification is needed; document the medication in the patient record

Answer

Use lower kVp to reduce tissue absorption

Answer

Use only bitewing radiographs to minimize the number of receptor insertions

Answer

Consult with the patient's physician about modifying the dose before the appointment

Question 7

When a patient with claustrophobia has difficulty tolerating intraoral receptor placement, the BEST initial approach is:

Accepted Answer

Use behavioral management techniques, discuss concerns, and consider extraoral imaging alternatives if needed

Answer

Inform the patient the procedure is brief and proceed as quickly as possible

Answer

Increase exposure time to ensure a diagnostic image on the first attempt and minimize insertions

Answer

Reschedule the appointment and refer the patient to a specialist for all future radiographs
