NBDHE Professional Ethics and Law Questions and Answers

Question 1

A dental hygienist completes a prophylaxis on an adult patient. Without discussing it first, the hygienist applies a fluoride varnish, assuming the patient would want it. The patient later expresses they did not want the treatment. This action could be legally classified as which of the following?

Accepted Answer

Battery

Answer

Battery is the intentional, unconsented touching of another person. Applying a treatment without consent, even if it is not harmful, constitutes battery because it violates the patient's right to autonomy over their own body. Negligence involves a breach of the standard of care resulting in harm, which is different from unconsented contact.

Question 2

A dental hygienist is asked by the employing dentist to use an outdated and less effective method for sterilization because it is faster. The hygienist knows this method does not meet the current CDC standard of care and could risk patient safety. By refusing to comply, the hygienist is primarily upholding which ethical principle?

Accepted Answer

Non-maleficence

Answer

The principle of non-maleficence dictates the duty to 'do no harm.' Using a substandard sterilization method could directly harm patients by failing to prevent cross-contamination. By refusing, the hygienist prioritizes patient safety and upholds this fundamental principle. Autonomy relates to the patient's right to decide, Veracity to truthfulness, and Justice to fairness.

Question 3

Which of the following is a permissible disclosure of Protected Health Information (PHI) under the HIPAA Privacy Rule without requiring the patient's specific written authorization?

Accepted Answer

Submitting a claim with diagnostic codes to the patient's insurance company for payment.

Answer

The HIPAA Privacy Rule permits covered entities to use and disclose PHI without patient authorization for the purposes of Treatment, Payment, and healthcare Operations (TPO). Submitting a claim to an insurance company clearly falls under the 'Payment' category. All other options represent violations of patient confidentiality.

Question 4

A dental hygienist with a standard license is working in a state where the administration of local anesthesia is not within the dental hygiene scope of practice. The dentist, who is running behind schedule, directs the hygienist to administer an infiltration to the patient. What is the hygienist's most appropriate and legal course of action?

Accepted Answer

Inform the dentist that this task is outside the legal scope of practice and respectfully decline.

Answer

A dental hygienist is legally and ethically bound to practice only within their state-defined scope of practice. Performing a task outside this scope, even under a dentist's direction, is illegal and can result in disciplinary action against the hygienist's license. The primary responsibility is to adhere to the law, protecting both the patient and one's professional license.

Question 5

A patient asks the dental hygienist if a dark spot on their radiograph is a cavity. The hygienist sees clear evidence of incipient caries, but the dentist has a policy of 'watching' these spots without alarming the patient. The hygienist feels conflicted about not being fully truthful. This situation creates a conflict between which two ethical principles?

Accepted Answer

Veracity and Beneficence

Answer

This dilemma involves a conflict between Veracity (the duty to be truthful and honest with the patient about clinical findings) and a misguided sense of Beneficence (the dentist's belief that withholding information is 'doing good' for the patient by avoiding alarm). The hygienist must balance the duty to provide complete information with the perceived intent to act in the patient's best interest.
