Which of the following can potentially threaten professional integrity?

The correct answer is truly related to professional integrity. Anxiety can lead to impaired judgment and decision-making, which may compromise a nurse's ability to provide safe, effective care. In high-pressure situations, such as those often encountered in healthcare settings, anxiety might cause a nurse to overlook critical details or become overly stressed, affecting their interactions with patients and their performance in clinical duties. This impact can challenge the adherence to professional standards and ethical guidelines that are essential for maintaining integrity in nursing practice.

Other factors present in the options may influence a nurse's performance but do not have the same direct and potential ramifications for professional integrity. Beneficence, for instance, is a fundamental ethical principle in nursing focused on promoting the well-being of patients, and it typically supports integrity rather than threatening it. A fast-paced environment can indeed create challenges for healthcare professionals, but it does not innately threaten integrity if the nurse is well-prepared and supported. Substance abuse presents a significant risk to a nurse's professional integrity, as it can severely impair judgment and behavior; however, anxiety, stemming from internal stressors rather than external maladaptive coping mechanisms, highlights a more subtle threat to maintaining the ethical standards expected in nursing practice.
