What is the priority nursing intervention for a patient during the immediate post-operative period?

Correct Answer: B

Rationale: Immediately post-op, airway patency is critical due to anesthesia's respiratory depression or obstruction risks (e.g., secretions). Hypoxia can kill in minutes, outranking hemorrhage (next priority), intake/output, or vitals monitoring. Nurses ensure breathing via positioning or suctioning, securing oxygenation foundational to all recovery processes, preventing rapid deterioration in this vulnerable phase.

Correct Answer: D

Rationale: Competence in nursing interventions requires knowledge (understanding theory and evidence), function (applying that knowledge practically), and specific skills (technical abilities like IV insertion). These three areas ensure a nurse can deliver safe, effective care tailored to patient needs. Leadership anatomy and skills is nonsensical leadership matters, but anatomy isn't a relevant term here, and it's not a trio with skills alone. Experience, advanced education, and skills include valuable elements, but experience isn't a core competency area; it enhances the trio, while advanced education overlaps with knowledge. Skills, leadership, and function mix unrelated concepts leadership is broader than intervention execution. Knowledge, function, and specific skills form a cohesive framework: knowing what to do, how to do it, and performing it proficiently, aligning with nursing standards for competent practice across diverse scenarios.

Correct Answer: B

Rationale: Maslow's hierarchy ranks physiological needs air, water, food as the most basic, essential for survival. Without these, higher needs (e.g., esteem) can't be met e.g., a hypoxic patient prioritizes breathing over relationships. Physical and psychological isn't a Maslow tier; it's vague, blending levels. Self-actualization, the top, involves fulfillment, reliant on all prior needs. Love and belonging, third-tier, depends on physiological and safety stability. In nursing, physiological needs like oxygen take precedence (e.g., stabilizing vitals before counseling), reflecting Maslow's logic: survival underpins all else, making this the most basic need driving care priorities.

Correct Answer: D

Rationale: The oxygen reservoir bag in a partial re-breathing mask stores oxygen, allowing the client to re-breathe the first third of exhaled air rich in oxygen, low in CO2 mixed with supplemental O2. This boosts FiO2 (40-60%) cost-effectively, ideal for moderate hypoxia (e.g., pneumonia). Encouraging CO2 re-breathing risks hypercapnia, opposite to intent. Reducing FiO2 contradicts the mask's purpose enhancing oxygen delivery. Precise FiO2 control fits non-rebreathing masks, not partial, which varies slightly. The re-breathing mechanism optimizes oxygen use, making this the correct function per respiratory care standards.

Correct Answer: D

Rationale: All listed are part of Maslow's hierarchy, addressing different levels of human needs.
