Which of the following actions can lead to a nursing license suspension in Florida?

Engaging in substance abuse while on duty is a serious violation of nursing laws and standards. This behavior directly compromises patient safety and undermines the integrity of the nursing profession. In Florida, nurses are subject to strict regulations that prohibit any form of substance abuse, as it affects their ability to perform their duties competently and safely. If a nurse is found to be under the influence of drugs or alcohol while caring for patients, it can lead to disciplinary actions, including the suspension or revocation of their nursing license, due to the high risk it poses to patient care.

In contrast, inadvertently missing a medication dose, while it is certainly a mistake that can happen, does not carry the same level of negligence or intent that substance abuse does. Similarly, taking an extended lunch break, while potentially unprofessional or against workplace policy, typically wouldn't result in such severe consequences unless it was part of a pattern of behavior that indicates a lack of responsibility. Updating patient records late, while important to address for continuity of care, also does not pose an immediate risk to patient safety like substance abuse does. Thus, engaging in substance abuse stands out as the action most likely to lead to suspension of a nursing license in Florida.
