Correct Answer: D

Rationale: The priority action for the nurse is to assess the client's mental status and level of consciousness. This assessment helps determine if the decreased respiratory rate is affecting the client's oxygenation. By evaluating the client's mental status and level of consciousness, the nurse can promptly identify any signs of respiratory distress or hypoxia, allowing for timely intervention and appropriate adjustments to the oxygen therapy or other treatments.

Correct Answer: D

Rationale: Obtaining information about a client's occupation and hobbies is crucial when assessing respiratory status as many respiratory problems can result from chronic exposure to inhalation irritants related to these activities. Understanding the client's potential exposure can help the healthcare professional identify risk factors and provide appropriate interventions to promote respiratory health.

Correct Answer: D

Rationale: The correct first intervention for a client experiencing hypoglycemia is administering 15-20 grams of fast-acting carbohydrate orally. If the client is conscious and able to swallow, providing quick-acting carbohydrates helps raise blood glucose levels rapidly and effectively. This approach is preferred over other options like administering insulin, dextrose solution intravenously, or glucagon, which are not the initial interventions for hypoglycemia.

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.
