Which is a potential consequence of drug or alcohol abuse by nurses?

Engaging in drug or alcohol abuse can significantly impair a nurse's ability to perform their duties safely and effectively. One of the most serious consequences of such substance abuse is the potential for license revocation. This occurs because nurses have a legal and ethical obligation to provide safe and competent care to their patients. When substance abuse affects their professional conduct, it can lead to disciplinary actions by the nursing board, including loss of licensure.

Additionally, there are legal repercussions that may follow substance abuse, such as criminal charges depending on the severity of the substance use, especially if it leads to harm to patients or if illicit substances are involved. Factoring in the impact on the work environment, such actions can deeply undermine a nurse's credibility and trustworthiness, ultimately jeopardizing their career.

The other options suggest beneficial outcomes or positive improvements, which are not associated with drug or alcohol abuse. The consequences of such behaviors are negative, affecting not only the nurse but also patients, colleagues, and the healthcare institution as a whole.
