Question 1

If the patient gags, the dental radiographer must:

Accepted Answer

If the patient gags, the dental radiographer must remove the film as quickly as possible to prevent the patient from vomiting or aspirating on the film. Waiting or discussing the issue may increase the patient's anxiety and discomfort.

Question 2

____ periapical films can be used to examine the edentulous arches.

Accepted Answer

Fourteen periapical films provide enough coverage to examine the edentulous arches. Eight films would only cover one arch, and twelve or eighteen films would be excessive.

Question 3

A developmental disability is a substantial impairment of mental or physical functioning that occurs before age ____ years and is of indefinite duration.

Accepted Answer

A developmental disability is a substantial impairment of mental or physical functioning that occurs before age 22 years and is of indefinite duration.

Question 4

When intraoral films are impossible to obtain, the radiographer should:

Accepted Answer

When intraoral films are impossible to obtain, the radiographer should resort to extraoral films to obtain the necessary diagnostic information. This may include panoramic or cephalometric radiographs. Skipping radiographs is not an option, and using local anesthetic on the patient's throat is unnecessary and potentially harmful. Using an intraoral digital film sensor may be an option, but it is not specified in the question whether this technology is available or not.

Question 5

The mixed occlusal and periapical examination consists of ____ size 4 films and ____ size 2 films.

Accepted Answer

The mixed occlusal and periapical examination typically consists of two size 4 films for occlusal views and four size 2 films for periapical views.

Question 6

The gag reflex is a(n) ____ effort, preceded by ____ of respiration.

Accepted Answer

The gag reflex is an involuntary effort,preceded by cessation of respiration.

Question 7

For a periapical examination in an edentulous patient, the film should be positioned so that approximately ____ of it extends beyond the edentulous ridge.

Accepted Answer

The film should extend approximately one-third beyond the edentulous ridge to ensure that the apices of the teeth are included in the radiograph.

Question 8

To help reduce the gag reflex:

Accepted Answer

Tactile stimuli, such as touching the tongue or soft palate with an instrument during a dental procedure, can trigger the gag reflex. By reducing such stimuli, the risk of gagging can be minimized. The other options are not effective in reducing the gag reflex. In fact, telling the patient to hold their breath may worsen the reflex, and distracting the patient or using the term "gagging" may increase anxiety and anticipation, leading to more gagging.

Question 9

If a person is blind or visually impaired, the dental radiographer must:

Accepted Answer

Since the person is visually impaired, clear verbal explanations should be provided to ensure understanding of the procedures being performed. Communicating using clear visual explanations may not be helpful for the individual. Gesturing to another person in the presence of the blind person may also not be helpful as they may not understand the meaning of the gesture. It is important to explain each procedure before performing it to ensure informed consent and comfort for the patient.

Question 10

Which film placement is most likely to elicit the gag reflex?

Accepted Answer

The maxillary molar film placement is most likely to elicit the gag reflex due to its proximity to the soft palate and posterior oral cavity, which are sensitive areas that can trigger the reflex.

Question 11

Which of the following suggestions are intended to help reduce the gag reflex?

Accepted Answer

Asking the patient to suspend an arm or leg in the air is a suggestion intended to help reduce the gag reflex;instructing the patient to breathe slowly through the nose is another;placing a small amount of table salt on the tip of the tongue is another;asking the patient to perform jumping jacks for 5 minutes in the treatment room is not a suggestion.

Question 12

Suggestions to avoid stimulating the gag reflex include:

Accepted Answer

Demonstrating film placement can help the patient understand the process and reduce anxiety, which may help in avoiding the gag reflex.

Question 13

Which of the following choices would represent the suggested film placement sequence for a patient who is likely to gag?
1) Anterior
2) Premolar
3) Molar

Accepted Answer

Starting with anterior films is recommended for patients who are likely to gag, as these areas are less likely to trigger the gag reflex.

Question 14

Size ____ film is typically used for the edentulous examination.

Accepted Answer

Size 2 film is typically used for the edentulous examination as it is large enough to capture a wide view of the upper and lower jaws, making it easier to detect any abnormalities, including bone loss or lesions. Size 0 and 1 films are too small and may not provide a clear picture, while size 4 films are too large and may be uncomfortable for the patient.

Question 15

In treating children with a primary or transitional dentition, the bisecting technique is preferred, because the small size of the mouth precludes the placement of a film beyond the apical regions of the teeth.

Accepted Answer

The bisecting technique is often used in children due to their smaller mouth size, which can make it difficult to place the film beyond the apical regions of the teeth, supporting both statements as true.

Question 16

A person with a physical disability may have problems with:
1) Vision
2) Hearing
3) Mobility

Accepted Answer

A person with a physical disability may have problems with vision, hearing, and mobility simultaneously. Therefore, all the options are correct.

Question 17

If the alveolar ridges of the patient are severely resorbed, the ____ technique is recommended for a periapical examination.

Accepted Answer

The bisecting technique is recommended for patients with severely resorbed alveolar ridges because it does not require the film to be placed parallel to the long axis of the tooth, which can be difficult in such cases.

Question 18

The gag reflex is elicited by stimulation of the sensitive tissues of the:

Accepted Answer

The answer of The gag reflex is elicited by stimulation...
