Correct Answer: C

Rationale: The most likely action by the nurse that would have prevented the negative outcome is providing more appropriate supervision of the UAP. Supervision is essential in delegation as it involves directing, evaluating, and following up on delegated tasks. By providing adequate supervision, the nurse can ensure that tasks are performed correctly and promptly identify any issues or abnormalities, such as a significant change in vital signs or the client's mental status. This proactive approach can help prevent adverse outcomes and enhance patient safety.

Correct Answer: B

Rationale: If the drainage from the chest tube decreases significantly, it may indicate a blockage by a clot, potentially leading to cardiac tamponade. The nurse's priority action should be to notify the healthcare provider immediately for further evaluation and intervention. Increasing suction, re-positioning the chest tube, or disassembling the tubing independently are not appropriate actions without healthcare provider guidance in this situation.

Correct Answer: D

Rationale: Seizure activity lasting longer than 5 minutes requires immediate intervention as it can lead to status epilepticus, a medical emergency.

Correct Answer: D

Rationale: The Institute of Medicine (IOM) report 'Health Professions Education: A Bridge to Quality' outlines five core competencies that healthcare providers should possess. These competencies include collaborating with an interdisciplinary team, implementing evidence-based care, providing family-focused care, using informatics in practice, and focusing on patient-centered care. Therefore, to ensure that nurses are practicing at their highest levels of competency as per the IOM report, the nurse manager should assess all of these areas.

Correct Answer: A

Rationale: The sound described is an S3 heart sound, which can indicate heart failure. The next appropriate action for the provider is to listen to the client's lung sounds. Lung sounds can provide additional information about the client's condition, especially when abnormal heart sounds are present. Calling the Rapid Response Team is not warranted based solely on the heart sound assessment. Having the client sit upright is not directly related to addressing the abnormal heart sound.
