shell electrons shifting to an inner vacancy?
A. Compton effect
B. Photoelectric effect
C. Thompson scattering
D. Coherent scattering: B. Photoelectric effect occurs when an inner shell electron is ejected and low level energy is
generated when an outer shell electron shifts to an inner vacancy.
A. Compton effect results from an incident electron ejecting an outer shell electron.
C. Thomson scattering occurs when an incident electron passes near an outer shell

electron causing vibration and ionization.
D. Coherent scattering is another name for Thomson scattering.
5. Craniofacial malformations that might cause malocclusions are seen in all of the following conditions
EXCEPT one.
A. Fetal alcohol syndrome
B. Bell's palsy
C. Cretinism
D. Down syndrome
E. Bilateral cleft lip and palate: B. Bell's palsy involves paralysis in muscles after bone formation is completed.
A. FAS involves multiple malformations and malocclusions.
C. Cretinism causes malformation in the eye spacing and jaw structure.
D. Down syndrome causes craniofacial malformation with malocclusions.
E. Bilateral cleft lip and palate create major developmental malformations of the palate and alveolar bone that can
cause malocclusion.
6. Which of the following radiographic projections would be MOST helpful in imaging the maxillary sinus?
A. Cephalometric
B. Lateral oblique mandible
C. Posterior-anterior skull
D. Transcranial
E. Waters' projection: E. The Waters' projection is used to image the maxillary sinuses.
A. The cephalometric projection is better used for orthodontic and facial reconstruc- tion.
B. The lateral oblique mandible projection images the mandible from the canine posteriorly to the body and ramus.
C. The posterior-anterior projection is better used to image changes in the cranial bones.
D.The transcranial projection is better used to image the temporomandibular joint.
7. A 42-year-old woman on no medications and with no significant past med- ical history is scheduled for
comprehensive dental hygiene care. Initially, she has no complaints about her health and her vital signs are within
normal limits. After you explain the procedure she will undergo and initiate the dental hygiene intervention, the
woman begins to complain of "feeling faint."
Questions 7-11 refer to this situation.:
, ••COMPREHENSIVE NBDHE: SHORT-FORM *100%
!
8. Q*7 : The initial emergency management for this woman should be
A. Recline the dental chair to the Trendelenburg position
B. Recheck vital signs to see if they are still normal
C. Give the woman a sugar-containing drink
D. Call in the dental office staff: A. Reclining in the chair will often abort a near syncopal episode and should be
the first thing done for this woman.
B. This should be done once the woman is reclined.
C. This is not indicated unless you have reason to believe that the woman is hypoglycemic.
D. Office staff may be alerted, but the chair should be reclined first.
9. Q*8 : In spite of the above treatment, the woman becomes very pale and loses consciousness. What is the
next step that must be initiated?
A. Place a bite block in the woman's mouth
B. Assess the airway and open the airway if necessary
C. Move the woman from the dental chair to the floor
D. Activate the emergency medical system (EMS): B. While the woman is re- clined, the airway may became
blocked so this is the first thing to be done. Based on the situation described, the most likely diagnosis in this woman is
syncope due to psychogenic factors.
A. This should not be done. It can cause harm.
C. No. The woman will benefit by remaining in the chair where the head will be lower than the legs, thus increasing
blood flow to the brain.
D. If there is any suspicion that the woman is suffering a major respiratory or cardiac event, the EMS should be
activated.
10. Q*9 : During the loss of consciousness all the following signs may be noted EXCEPT one. Which is the
EXCEPTION?
A. Weak pulse
B. Flaccid muscles
C. Shallow respirations
D. "Fruity" breath odor: D. "Fruity" breath odor is associated with diabetic emer- gency (hyperglycemia).
***A weak pulse, flaccid muscles, and shallow respirations may be seen in syncope.
11.Q*10: As this woman regains consciousness, what is she MOST likely to experience?
A. Her pulse rate and blood pressure return to normal
B. She should be walked out of the room as soon as possible to avoid

recurrence of this event
C. She will feel very sleepy: A. After syncopal episode, vital signs return to normal.
B. The woman should stay in a reclined position for several minutes to avoid a recurrence of this event.
C. This woman should not feel tired after she recovers. Post-seizure patients may feel sleepy
12.Q*11 : Once this woman states she is feeling fine, what should the dental hygienist do?
A. Discharge client from your care and allow her to go home
B. Transport her to the nearest hospital for evaluation
C. Encourage her to be evaluated by her primary care physician as soon as possible: Once vital signs are normal
and the woman feels well, she may go home. No need for medical assistance unless the woman does not recover fully or
there are other signs or symptoms that make you feel it was more serious than just a syncopal episode.
13.Of the descriptions below, what is MOST characteristic of the atrioventric- ular (AV) valve of the heart?
A. Has two flaps
B. Is also called the mitral valve
C. Is located between the right atrium and the right ventricle
D. Is located between the left atrium and the left ventricle: C. This one-way valve is located between the right atrium
and the right ventricle.
A. The AV valve has three flaps.
B. The bicuspid valve is also called the mitral valve.
D. The bicuspid valve is located between these two heart valves.
14.When an antifungal ointment is applied before a culture is taken to areas of angular cheilitis, which of the
following diagnostic categories is being used?
A. Therapeutic
B. Clinical
C. Laboratory
D. Differential
E. Historical: A. Therapeutic diagnosis involves use of a medication to see if the suspected condition resolves.
B. Clinical diagnosis is made based upon the clinical picture.
C. Laboratory diagnosis is based upon laboratory tests.
D. Differential diagnosis may involve multiple comparative factors.
