When caring for a client with a femoral venous catheter, it is essential for the nurse to:

Correct Answer: B

Rationale: A femoral venous catheter, inserted into a large vein, poses a high infection risk if not handled properly. Maintaining sterile technique during care prevents introducing pathogens, which could lead to bloodstream infections, a serious complication. Irrigating with saline isn't standard unless ordered, as it risks dislodging clots or causing fluid overload. Assessing dressings for bleeding is important but secondary to infection prevention, as sterile technique addresses the root cause of complications. Limiting mobility reduces dislodgement risk but isn't the primary focus compared to infection control. Sterile technique aligns with evidence-based practice to ensure patient safety and catheter functionality.

Correct Answer: C

Rationale: Albuminuria (protein loss in urine) reduces plasma albumin, lowering colloid oncotic pressure, which normally keeps fluid in vessels. This imbalance lets fluid leak into tissues, causing edema. Hydrostatic pressures and tissue osmotic pressure play lesser roles. Nurses manage this with albumin infusions, addressing the root cause to reduce swelling and support circulation.

Correct Answer: B

Rationale: Sister Callista Roy's Adaptation Model posits that individuals are adaptive systems interacting with a changing environment, where managing stressors fosters health and change. Nurses, per Roy, facilitate adaptation by manipulating environmental stimuli, aligning with the question's focus on stressor manipulation. Dorothea Orem's Self-Care Deficit Theory emphasizes self-care abilities, not stressor adaptation as a change mechanism. Imogene King's Goal Attainment Theory focuses on nurse-patient interactions to achieve health goals, not specifically stressor manipulation. Virginia Henderson's model defines nursing through 14 basic needs, prioritizing care assistance over adaptation to stressors. Roy's theory uniquely ties adaptation and stressor management to fostering change, as patients adjust to physical, emotional, or social challenges, making her the theorist best matching this description.

Correct Answer: B

Rationale: Nursing's code of ethics, like the ANA's, defines principles autonomy, beneficence, justice, nonmaleficence guiding how nurses deliver care. It shapes professional conduct, ensuring respect for patient rights, dignity, and needs (e.g., informed consent). Improving self-health care applies to nurses personally but isn't the code's focus, which prioritizes clients. Ensuring identical care misinterprets ethics; it promotes fairness, not uniformity, as care varies by patient. Protecting clients from harm is an outcome of ethical practice (nonmaleficence), but the code's broader purpose is defining care principles, not just safety. These principles provide a moral framework, enabling nurses to navigate complex decisions, uphold trust, and maintain professionalism, making this the most comprehensive description of the code's role.

Correct Answer: B

Rationale: Good communication and critical thinking are paramount for accurate client information. Communication asking clear questions, listening elicits reliable responses (e.g., pain details), while critical thinking interprets them (e.g., linking symptoms), ensuring precision. Teaching and assessment are roles, not skills for extraction; teaching informs, not gathers. Cognitive skills and teaching experience overlap with critical thinking but miss communication's primacy experience aids, doesn't define. Psychomotor skills (e.g., measuring BP) collect objective data, not client perceptions. Together, communication and critical thinking unlock subjective insights, vital for a thorough, accurate assessment in nursing.
