Patient Management Component

Part A

This part consists of multiple-choice type questions with one or more correct answers.

It is given in a 1½ hour examination session held during the afternoon of the second day.

Part A consists of an extended match examination. Questions may include

photographs of radiographs; or, casts and models; or, patients and a patient case history.

One or more responses may be correct and candidates are required to answer with the

most appropriate response or responses. Each question will require the candidate to

review the background information supplied and answer extended match questions.

Sample Questions :
Using the case history and photograph 1, answer the following question on the

answer score sheet.

Dental History:	Irregular visits due to anxiety.
Medical History: Significant Findings: Current Medication: Allergies:	Multiple allergies to medication.
Social/Family History: Significant Findings:	Smoker, 1 package/day for 35 years.
Clinical Examination: Significant Findings: Extraoral: Intraoral:	See Photograph 1 Slight, bilateral swelling of neck and throat. Rampant caries.

Photograph 1

Sample Question: 1 (Select ONE OR MORE correct answers.)
The most likely differential diagnosis (diagnoses) for the patient’s decrease in blood pressure,

pulse and respiration is (are)
