Example of Dental Hygiene Exam Independent Questions: Pick the best answer for each

During the treatment of Mr. Brown, 55 years old, the dental hygienist notices a suspicious lesion on his tongue. What is the next best step?

a. Proceed with the planned treatment without addressing the lesion.

b. Advise Mr. Brown to monitor the lesion and return if it changes.

c. Immediately refer Mr. Brown to an oral surgeon for further evaluation.

d. Document the finding and continue with the dental hygiene care plan.

Rational:
C: Immediately refer Mr. Brown to an oral surgeon for further evaluation, because any suspicious lesion, especially in a 55-year-old, requires prompt specialist assessment to rule out serious conditions.

After reviewing the health history of Sarah, a 22-year-old patient, it’s noted that she is currently pregnant. Which consideration is most important for her dental hygiene care plan?

a. Avoid all dental treatments until after the pregnancy.

b. Schedule appointments during her second trimester.

c. Use only natural cleaning agents during her treatments.

d. Double the length of her dental hygiene appointments.

Rational:
C: Schedule appointments during her second trimester, as this period is generally considered the safest time to provide dental care for pregnant patients.

The dental radiograph of Emily, 18 years old, shows that she has impacted wisdom teeth. What is the most appropriate action?

a. Schedule her for immediate extraction of the wisdom teeth.

b. Monitor the situation and reassess in six months.

c. Recommend a soft diet to prevent discomfort.

d. Apply topical fluoride to the adjacent teeth as a preventive measure.

Rational:
B: Monitor the situation and reassess in six months, because impacted wisdom teeth may not always require immediate extraction and can be observed for changes or symptoms.

After a dental cleaning, John, 40 years old, reports excessive sensitivity. Which of the following is the best immediate action?

a. Prescribe a high-dose pain reliever.

b. Schedule him for a follow-up in one week without taking any immediate action.

c. Advise him to avoid hot and cold foods.

d. Apply a desensitizing agent to the affected areas.

Rational:
D: Apply a desensitizing agent to the affected areas, because it directly addresses the sensitivity issue by creating a barrier over the sensitive spots, providing immediate relief.

A dental hygienist needs to evaluate the progress of oral hygiene instruction given to a 10-year-old child. Which method is most effective?

a. Check for plaque removal efficiency at the next visit.

b. Send home a quiz on oral health practices for the child to complete.

c. Review the number of new cavities at the next check-up.

D. Ask the child to demonstrate their brushing technique.

Rational:
D. Asking the child to demonstrate their brushing technique, is most effective because it directly assesses the child’s understanding and application of the oral hygiene instructions given.

Mrs. Lee, 60 years old, complains of dry mouth during her dental visit. Which condition is she at risk for due to xerostomia?

a. Accelerated orthodontic movement.

b. Increased incidence of dental caries.

c. Excessive production of saliva.

d. Enhanced taste sensation.

Rational:
B. Increased incidence of dental caries, because dry mouth (xerostomia) reduces saliva, which normally helps protect teeth from decay by washing away food particles and neutralizing acids.

Example Dental Hygiene Exam Case Questions:

CASE STUDY: Mrs. Thompson

Client Profile:
Mrs. Thompson, a 45-year-old woman and is a manager, leading a busy lifestyle due to her job nature. She expresses concern about her oral health as she has been experiencing sensitivity to hot and cold beverages.

Chief Concern:
Mrs. Thompson reports sensitivity and occasional discomfort in her lower left molar region. She also mentions a recent increase in gum bleeding during brushing.

Health History:
Mrs. Thompson has been diagnosed with Type 2 diabetes, which is currently managed with oral hypoglycemics. She notes her diet is high in sugary snacks due to her busy schedule and often forgets to take her medication on time.

Dental History:
Mrs. Thompson admits to an inconsistent oral hygiene routine, primarily due to her busy work schedule. She last visited a dentist over a year ago for a routine cleaning.

Intraoral Assessment:
Examination reveals generalized mild gingival inflammation and plaque accumulation, especially around the lower molars. Probing depths range from 2 to 4 mm in the lower left molar region, with noticeable recession and sensitivity noted upon examination.

Questions: Pick the best answer for each

What is the primary factor the dental hygienist should consider when planning Mrs. Thompson’s treatment?

a. Her preference for dental appointment times.
b. Her Type 2 diabetes management.
c. Her job as a manager.
d. Her favorite sugary snacks.

Rational:
B: Type 2 diabetes significantly impacts oral health and can affect the healing process, the risk of infections, and the management of periodontal disease. Therefore, a dental hygienist must prioritize understanding and integrating a patient’s diabetes management into their treatment planning to ensure safe, effective care, and tailor preventive strategies accordingly.
How should the dental hygienist assist Mrs. Thompson in managing her sensitivity and gum bleeding?

a. Suggest switching to a soft-bristled toothbrush and sensitivity toothpaste.
b. Recommend immediate surgical intervention.
c. Advise ceasing all consumption of sugary snacks immediately.
d. Prescribe antibiotics for her gingival inflammation.

Rational:
A: Suggest switching to a soft-bristled toothbrush and sensitivity toothpaste. Switching to a soft-bristled toothbrush and sensitivity toothpaste is often the first line of approach to manage sensitivity and gum bleeding without immediate invasive procedures. This recommendation addresses the symptoms by reducing mechanical irritation from brushing and protects against sensitivity, potentially improving oral hygiene practices without the side effects associated with more aggressive treatments.
Which intervention would likely be most effective in improving Mrs. Thompson’s oral health long-term?

a. Setting up a strict dietary plan to eliminate sugar.
b. Collaborating on a manageable oral hygiene routine that fits her schedule.
c. Advising her to change her profession to reduce sedentary behavior.
d. Implementing frequent professional dental cleanings without addressing her home care routine.

Rational:
B: collaborating on a manageable oral hygiene routine that fits her schedule, would likely be most effective because it addresses the root of her oral health issues—her inconsistent oral hygiene—while considering her busy lifestyle for sustainable improvement.
Considering Mrs. Thompson’s health history, which complication is most crucial to monitor during her dental treatment?

a. Immediate allergic reactions to dental materials.
b. The likelihood of her forgetting dental appointments.
c. Increased risk of tooth decay due to her job.
d. Potential for rapid progression of periodontal disease due to her diabetes

Rational:
D: Potential for rapid progression of periodontal disease due to her diabetes, because poorly controlled diabetes can significantly impair wound healing and increase susceptibility to infections, making periodontal disease management critical.

To sum up, you can ace the dental hygiene board exam by understanding its format, focusing on important competencies and patient types in your studies. Let these tips shape your study strategy and take on the exam confidently, equipped for success becoming a Dental Hygienist. Best of luck!
