Which of the following is a practical obstacle to maintaining confidentiality?

Correct Answer: B

Rationale: The correct answer is 'Information about patients is increasingly stored on large electronic databases which may not be secure.' This is a practical obstacle because the potential lack of absolute security in storing patient information on electronic databases can lead to breaches of confidentiality, unlike the number of professionals involved or approved research, which are managed under ethical guidelines.

Correct Answer: C

Rationale: In certain situations, it may be necessary to override the truth-telling principle for valid reasons. One such reason is when patients do not wish to know the truth, especially if the news is bad. Respecting the autonomy and emotional well-being of patients is crucial, and if they explicitly express their preference to not be informed about negative outcomes, it may be ethically justifiable to withhold the truth.

Correct Answer: C

Rationale: Monitoring the client as warranted by their condition and as ordered is a key way to prevent assessment errors, ensuring timely and appropriate care.

Correct Answer: C

Rationale: Wasted time is an outcome, not an unethical behavior; the others are consequences of unethical actions, not behaviors themselves.

Correct Answer: D

Rationale: Prediabetes increases the risk of type 2 diabetes, not type 1, which is an autoimmune condition unrelated to prediabetes.
