Free TX-DJA Practice Questions

Question 1

An impacted mandibular third molar is scheduled for extraction. The patient signs a generic consent form, but the dentist never discusses the material risk of inferior alveolar nerve injury or reasonable alternatives. The patient asks no questions. The signed form is:

Accepted Answer

Insufficient because a signature does not replace disclosure of material risks and alternatives

Answer

Sufficient unless the patient specifically requests an explanation of risks and alternatives

Answer

Sufficient because nerve injury is a recognized complication of the procedure

Answer

Insufficient only if the patient later experiences permanent numbness

Question 2

Diagnostic radiographs have already been prescribed for an established patient. A properly registered dental assistant has current radiology authorization; the dentist remains responsible for the practice but is off-site. Under Texas supervision rules, the assistant:

Accepted Answer

May expose the radiographs under general supervision if all radiography requirements are met

Answer

Must postpone the radiographs because every delegated duty requires direct supervision

Answer

May position the receptor, but may not expose it until the dentist is physically present somewhere in the dental office

Answer

May independently select and expose whatever images appear clinically useful

Question 3

At the last visit, a patient was 10 years old. Six years later, the patient is now 16. For an ordinary dental record, not a customized orthodontic-device record, the practice must retain it until at least:

Accepted Answer

The patient's 21st birthday

Answer

Five years after the last treatment date

Answer

The patient's 18th birthday

Answer

Seven years after the last treatment date

Question 4

A dentist has reviewed the patient's monitoring-program history and is treating uncomplicated acute post-extraction pain. The patient is not receiving cancer, hospice, palliative, or end-of-life care. Which prescription stays within both the Texas 10-day ceiling and the no-refill rule?

Accepted Answer

24 tablets, one every 8 hours as needed, with no refill

Answer

20 tablets, one every 6 hours as needed, with one refill

Answer

42 tablets, one every 6 hours as needed, with no refill

Answer

36 tablets, one every 8 hours as needed, with no refill

Question 5

Intended moderate sedation has drifted: the patient is not easily aroused, responds purposefully only after repeated painful stimulation, may require airway intervention, and has inadequate spontaneous ventilation. The achieved depth is:

Accepted Answer

Deep sedation

Answer

Moderate sedation

Answer

Minimal sedation

Answer

General anesthesia

Question 6

Through teledentistry, a dentist plans to supervise six non-dentist health professionals at the same time while they collect digital oral images solely for screening and assessment. Before the session begins, the dentist must:

Accepted Answer

Reduce the number under simultaneous supervision to five; image collection may continue

Answer

Keep all six only if every image is reviewed in real time

Answer

Reduce the team to four because the supervising dentist counts toward the five-person limit

Answer

Cancel delegated imaging because only dentists and hygienists may capture screening images

Question 7

A sterilizer's time, temperature, and pressure readings are normal, and its internal and external chemical indicators changed appropriately. The biological spore test is positive. Select the proper next step.

Accepted Answer

Remove the sterilizer from service, review operating procedures, repeat the biological test immediately with the same cycle parameters, and return it only after satisfactory verification

Answer

Continue routine use and repeat biological monitoring at the next scheduled interval because the other indicators were normal

Answer

Run an empty cycle with a new chemical indicator and resume use if the indicator changes

Answer

Quarantine implantable items only, but continue processing other instruments while awaiting a repeat spore test

Question 8

At the close of a two-year renewal period, a direct-care Texas dentist has 24 continuing-education hours, including 16 clinical or technical hours and 4 pain-management hours. All 4 pain-management hours were completed in year one. How should the renewal be evaluated?

Accepted Answer

Not compliant because two pain-management hours are required in each year

Answer

Compliant because four pain-management hours were completed during the biennium

Answer

Compliant if the jurisprudence assessment was also completed during the period

Answer

Deficient only by two clinical hours, with no pain-management shortfall

Question 9

STOP-BANG yields six positive findings. The patient asks the dentist to diagnose obstructive sleep apnea and fabricate an oral appliance without involving a physician. The dentist should:

Accepted Answer

Explain that the score indicates high screening risk, not a diagnosis, and coordinate appliance treatment with a licensed physician

Answer

Diagnose obstructive sleep apnea because a score of five or more is sufficiently specific to establish the disorder without medical consultation

Answer

Fabricate the appliance now because dentists may treat high-risk screening results independently, then refer if symptoms persist

Answer

Repeat STOP-BANG after a trial of appliance therapy and use the later score to confirm the diagnosis

Question 10

A patient repeatedly misses appointments and has an unpaid balance. The dentist elects to end nonemergency care. Select the termination plan that meets Texas continuity-of-care requirements.

Accepted Answer

Send at least 30 days' written notice by hand or certified mail, explain ongoing needs and record access, recommend another dentist, and remain available for emergencies for up to 30 days

Answer

Send written notice immediately, end emergency coverage at once, and withhold record copies until both the copying charge and treatment balance are paid

Answer

Send 15 days' notice by certified mail, provide referral and record instructions, and remain available for emergencies only until the notice date

Answer

Continue elective treatment and emergency coverage until another dentist formally accepts the patient, regardless of future missed appointments or nonpayment
