To implement nursing care interventions the nurse must be competent in three areas which are:

Correct Answer: D

Rationale: Competent intervention requires knowledge (theory, e.g., drug effects), function (practical application, e.g., administration), and specific skills (techniques, e.g., injections). This trio ensures safe, effective care e.g., giving antibiotics demands understanding, execution, and precision. Leadership, autonomy, and skills mix role traits with ability, missing function's practical focus leadership coordinates, not implements. Experience, advanced education, and skills enhance competence, but experience isn't a core area; it builds on knowledge, while education overlaps. Skills, leadership, and finances are disjointed finances aren't clinical, and leadership is broader. Knowledge, function, and skills form a cohesive base, enabling nurses to act proficiently across scenarios, aligning with standards for intervention delivery.
