8. A dental professional MUST have knowledge of the anatomic aspects of the spaces of the head and neck when examining a patient BECAUSE these spaces can be involved in infections arising in dental tissue.
a. Both the statement and the reason are correct and related.
b. Both the statement and the reason are correct but NOT related.
c. The statement is correct, but the reason is NOT.
d. The statement is NOT correct, but the reason is correct.
e. NEITHER the statement NOR the reason is correct.
ANS: A
Feedback
A The statement is correct. Dental professionals MUST know the anatomic aspects of the spaces because this allows the dental professional to form a three-dimensional view of the head and neck anatomy, and it also will permit the dental professional to identify and understand possible infections occurring within the head and neck. The reason is also correct because these spaces communicate with each other directly, as well as through their blood and lymph vessels. In addition, the statement and the reason are related. Both relate to the spaces, the role of the spaces, and the importance of considering these spaces during the patient examination.
B The statement and the reason are correct and they are related. Dental professionals MUST know the anatomic aspects of the spaces because this allows them to form a three-dimensional view of the head and neck anatomy and permits them to identify and understand possible infections occurring within the head and neck. Also, these spaces communicate with each other directly, as well as through their blood and lymph vessels.
