The master gland controls the thyroid hormone by secreting

Correct Answer: C

Rationale: The pituitary secretes TSH e.g., stimulates thyroid unlike thyroxine, T3 (thyroid products), calcitonin (calcium). Nurses understand e.g., TSH tests for regulation, per endocrine.

Correct Answer: A

Rationale: The Quality and Safety Education for Nurses (QSEN) initiative defines key competencies to ensure nurses deliver safe, high-quality care, addressing modern healthcare demands. Evidence-based practice integrates the best research with clinical expertise, guiding decisions for effective outcomes. Client-centered care prioritizes individual needs and preferences, balancing advocacy with safety. Informatics leverages technology for accurate documentation and care evaluation, enhancing efficiency. Quality improvement drives ongoing assessment and refinement of practices, while teamwork and collaboration ensure coordinated care delivery. Safety minimizes risks, a core QSEN focus. Nursing certification, though valuable, isn't a QSEN competency, as it's an individual credential, not a universal standard. These standards collectively equip nurses to improve care quality and safety across settings, reflecting a comprehensive approach to professional development and patient well-being.

Correct Answer: B

Rationale: Nursing research's primary aim is to generate knowledge to guide practice, building a scientific foundation that informs and improves care delivery. This involves studying interventions like pain management techniques or outcomes, like recovery rates, to create evidence-based guidelines that enhance safety and effectiveness. Decreasing costs, while a potential byproduct, isn't the core focus; research prioritizes quality over economics. Delegating tasks relates to workflow, not research goals, and assisting physicians, though collaborative, isn't nursing's aim its focus is autonomous advancement. This knowledge generation refines assessment, planning, and intervention, ensuring nurses address client needs with precision. For example, research on pressure ulcer prevention shapes protocols, directly impacting practice. This purpose elevates nursing as a science-driven profession, distinct from mere support roles, fostering innovation and accountability in healthcare.

Correct Answer: C

Rationale: Critical appraisal in nursing research evaluates evidence quality and relevance post-literature review, ensuring findings guide practice effectively. Asking 'What were the results of each study?' identifies outcomes like reduced infection rates while 'Are the results valid and reliable?' assesses methodological rigor, checking biases or sample issues. 'Will the results improve client care?' gauges practical impact, linking evidence to real-world benefits. 'How many studies were found?' or 'Where were they conducted?' provide context but don't appraise quality. This process filters robust evidence like a study on hand hygiene reducing infections ensuring nurses apply trustworthy, applicable insights. It's a gatekeeper, preventing flawed data from skewing care, and aligns research with nursing's goal of enhancing patient outcomes through science, not just volume or geography.

Correct Answer: A

Rationale: Holistic care in nursing embraces the whole person mind, body, spirit requiring tailored approaches. Understanding and respecting each person's definition of health acknowledges their unique values, like viewing wellness as independence or spiritual peace, shaping care plans. Respecting responses to illness honors individual coping like stoicism or seeking support fostering trust. A standard health definition ignores this diversity, risking alienation, while calling health inactive contradicts its dynamic nature people actively pursue it. Holistic nursing uses models like the wellness wheel to integrate dimensions, ensuring care fits the client, not a mold. This flexibility enhances engagement, as when a nurse adapts teaching for a client valuing herbal remedies, strengthening outcomes by aligning with personal beliefs and experiences.
