The nurse is reviewing the literature to identify evidence-based practice research that supports a new procedure using a new product when changing the central line catheter dressing. Which research article would best support the nurse's proposal to change the procedure?
The review-of-literature article that cited ambiguous statistics about the product.
The article in which the study was conducted by the manufacturer of the product used.
The research article included 10 subjects participating in the study.
The review-of-literature article that cited numerous studies supporting the product
The Correct Answer is D
Evidence-based practice (EBP) relies on the hierarchical synthesis of clinical research to validate procedural changes and improve patient outcomes. Systematic reviews and meta-analyses occupy the highest levels of the evidence pyramid, providing a rigorous evaluation of multiple studies. This approach minimizes sampling bias and ensures that nursing interventions are grounded in statistically significant, reproducible scientific data.
Rationale:
A. Ambiguous statistics indicate a lack of statistical significance or clarity in the research findings, making the data unreliable for clinical application. Evidence used to change hospital policy must demonstrate internal validity and clear, consistent results to ensure patient safety. Articles with vague or conflicting data cannot justify a shift in standardized protocols.
B. Research conducted by the manufacturer presents a significant conflict of interest, which can compromise the objectivity of the study results. Independent, peer-reviewed research is necessary to eliminate commercial bias and ensure the product’s efficacy is evaluated neutrally. Trustworthy EBP requires findings that are free from financial influence or industry-driven motives.
C. A study with only 10 subjects has an inadequate sample size, which severely limits the generalizability of the findings to a broader population. Small cohorts lack the statistical power required to prove that results are not due to mere chance. For central line care, robust data from large, multi-center trials are essential to mitigate clinical risks.
D. A review-of-literature that synthesizes numerous studies represents a systematic approach to evidence, offering the strongest support for a new procedure. These articles aggregate diverse data points to confirm the clinical efficacy and safety of a product across various settings. This high-level evidence provides the necessary scientific justification for modifying nursing practice and improving infection control.

Correct Answer is ["B","C","D"]
Explanation
Interprofessional collaboration involves shared decision-making and synergistic influence among diverse practitioners. It requires mutual respect to optimize patient outcomes and address complex healthcare delivery systems through integrated clinical expertise and unified goals.
Rationale:
A. Restricting leadership roles to a single profession inhibits the collaborative spirit. Interprofessional teams should rotate the facilitator role to ensure all disciplines have equal representation and influence during clinical coordination meetings.
B. Effective teams must acknowledge expertise inherent in various disciplines. Valuing the unique professional contributions of each member fosters trust and ensures that specific clinical knowledge is utilized for comprehensive patient care plans.
C. Promoting active involvement ensures that diverse perspectives are applied to problem-solving. When staff feel empowered to offer solutions, it improves organizational efficiency and enhances the overall quality of the healthcare environment.
D. Managers must foster a supportive culture that encourages professional development. An inclusive environment minimizes hierarchical barriers, allowing junior and senior staff from different departments to engage in meaningful, non-threatening clinical dialogue.
E. Effective collaboration relies on assertive, not aggressive communication, which creates hostility. Open and respectful dialogue is necessary to prevent medical errors and ensure that information is exchanged accurately among the interprofessional team.
Correct Answer is A
Explanation
Autonomic dysreflexia is a life-threatening neurological emergency occurring in spinal cord injuries at T-6 or above. It involves uninhibited sympathetic discharge triggered by noxious stimuli, causing extreme hypertension and potential cerebral hemorrhage. Immediate nursing intervention focuses on elevating the head and removing the triggering stimulus, such as a distended bladder.
Rationale:
A. This client is the priority due to the risk of status epilepticus or stroke from hypertensive crisis. Autonomic dysreflexia requires immediate vasodilation and assessment of the urinary or bowel systems. The nurse must act fast to prevent permanent neurological damage or sudden cardiovascular collapse.
B. Huntington's disease involves progressive neurodegeneration characterized by chorea, which are involuntary, jerky movements. While these symptoms are distressing and increase metabolic demands, they are expected findings in the middle stages of the disease. This client does not require immediate, life-saving stabilization over others.
C. Guillain-Barre syndrome involves demyelination causing ascending weakness, which is currently only at the knees. While the nurse must monitor for respiratory failure, the paralysis has not yet reached the diaphragm or intercostal muscles. This client is stable but requires frequent neurological checks throughout the shift.
D. The "pill-rolling" tremor is a classic, rhythmic resting tremor associated with dopamine depletion in the basal ganglia. It is a hallmark sign of Parkinson's disease and does not indicate acute physiological distress. This client’s needs are chronic in nature and do not take priority over emergency conditions.
