Correct Answer: B

Rationale: Patients prescribed carbidopa-levodopa should be informed that it may take several weeks for the medication to reach its full therapeutic effectiveness in managing Parkinson's disease symptoms. This delayed onset of action is important for patients to be aware of to prevent premature discontinuation of the medication due to perceived lack of efficacy.

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: The priority for a nurse working on an inpatient medical-surgical unit is to ensure client safety. This is crucial as errors in hospital care can lead to preventable deaths. While attending to holistic client needs and providing client-focused care are important aspects of nursing, ensuring client safety takes precedence to prevent harm and promote positive patient outcomes.

Correct Answer: B

Rationale: Clients with a history of heart failure generally have negative findings, such as shortness of breath. The nurse needs to determine whether the client's activity is the same or worse, or whether the client identifies a decrease in activity level. Trouble breathing, chest pain, breathlessness at night & peripheral edema are symptoms of heart failure, but do not provide data that can determine the extent of the client's heart failure.

Correct Answer: A

Rationale: Depression can occur in clients with heart failure, especially in older adults. When a client expresses thoughts of being a burden and death, it is crucial for the nurse to address these concerns. Offering to talk more about the client's feelings provides an opportunity for open communication and a deeper understanding of the client's emotions. Open-ended questions like the one in choice A encourage the client to express themselves freely, leading to better assessment and client-centered care. Choices B and C fail to address the client's emotional distress directly, and choice D diverts the focus without addressing the client's immediate concerns.
