A nurse is caring for a client admitted with a diagnosis of acute kidney injury. The client asks the nurse, "Are my kidneys failing and will I need a kidney transplant?" The nurse should respond to the client with which of the following statements?

A. Client develops petechiae on the arms, legs, and abdomen: Petechiae can indicate thrombocytopenia, which may be a complication of heparin therapy but is not an urgent concern unless severe or associated with bleeding.

B. Health care provider orders Coumadin 2.5 mg P.O. to begin today: Coumadin (warfarin) is often initiated as a bridge therapy or overlap with heparin therapy in pulmonary embolism management. This order is not necessarily inappropriate and may be part of the treatment plan.

C. Client develops slight ecchymosis at the venipuncture site: Ecchymosis at the venipuncture site can occur due to minor trauma during the insertion of IV lines or blood draws and is not necessarily indicative of a complication requiring immediate notification of the healthcare provider.

D. Client's partial thromboplastin time (PTT) is 70 seconds and the control is 25-40 seconds: A significantly elevated PTT indicates a potential overdose of heparin, putting the client at risk of bleeding complications. This finding warrants immediate notification of the healthcare provider for further evaluation and possible adjustment of heparin therapy.

A. Poorly coordinated care and nosocomial infections are examples of errors: Poorly coordinated care, such as miscommunication between healthcare providers or lack of continuity in care, and nosocomial infections (infections acquired in the healthcare setting) are examples of errors that can compromise patient safety and contribute to adverse events.

B. Handoff errors are not causes of adverse events: Handoff errors, including miscommunication during transitions of care, are significant contributors to adverse events in healthcare settings. Improper handoffs can lead to misunderstandings, delays in treatment, and errors in medication administration.

C. Medication errors are intentional: Medication errors are unintended and can occur due to various factors, including human error, system failures, and communication breakdowns. They are not intentional acts.

D. As many as 10% of medication errors are preventable: Medication errors are often preventable with the implementation of safety measures such as barcode scanning, medication reconciliation, and standardized protocols. The percentage of preventable medication errors may vary depending on the healthcare setting and the effectiveness of safety initiatives.
