A nurse is teaching a client about skin cancer prevention. Which of the following statements by the client indicates an understanding of the teaching?

Rationale:

A. Fibrinogen level: Fibrinogen is a clotting factor that can reflect coagulation activity, but it is not used to monitor warfarin therapy. It is more relevant in conditions like DIC or liver disease, not for warfarin dose adjustments.

B. aPTT: Activated partial thromboplastin time (aPTT) is used to monitor heparin therapy. Warfarin, which affects the extrinsic pathway of coagulation, does not significantly impact aPTT levels.

C. INR: The international normalized ratio (INR) is the standard test used to monitor warfarin therapy. It reflects the effect of warfarin on prothrombin time and guides safe and effective dosing to maintain therapeutic anticoagulation.

D. Platelet count: While platelet count helps evaluate bleeding risk and detect thrombocytopenia, it is not used to guide warfarin dosing. Warfarin works by inhibiting vitamin K–dependent clotting factors, not by affecting platelet production.

Rationale:

A. Identify possible precipitating factors related to the infections: The first step in addressing a quality or safety concern is to assess the situation and collect data. Identifying contributing factors helps guide appropriate interventions and ensures that any subsequent actions are targeted and evidence-based.

B. Meet with providers to discuss measures to decrease the infections: Collaborating with providers is essential for implementing effective solutions, but this step should follow a thorough assessment. Without identifying root causes first, discussions may be unfocused or ineffective in reducing infection rates.

C. Schedule nursing staff training for infection control procedures: Training is a critical part of reducing catheter-associated infections, especially if staff knowledge gaps are discovered. However, education should be informed by a needs assessment and data on what factors are contributing to the infections.

D. Revise the current policy for catheter care: Policy revision may be necessary if current guidelines are outdated or inadequate. However, revising policy prematurely, without understanding the source of the problem, may lead to unnecessary or ineffective changes.
