Exam 2 Comprehensive Study Notes on EBP, Nursing Process, and Prioritization

Evidence-Based Practice in Nursing

• Definition and Core Purpose:

  • Evidence-Based Practice (EBP) is a systematic approach to clinical practice that integrates the best available scientific evidence with clinical expertise and patient values to deliver high-quality care.

  • Chart audits are regularly performed by specialized personnel to review patient care records, ensuring clinical practices adhere to current evidence-based guidelines.

• Primary Goals of Evidence-Based Practice:

  • Increases patient satisfaction with care received.

  • Improves overall health outcomes and long-term patient well-being.

  • Achieves optimal clinical outcomes through proven interventions.

  • Generates positive financial impacts by reducing care costs, maximizing facility revenue, and supporting staff raises.

• Dynamic Nature of Evidence:

  • Infection control guidelines implemented during the COVID-19 pandemic serve as a prime example of EBP evolution.

  • As understanding of the disease process updated over time, facility infection control protocols were continuously adapted to align with emerging data.

The Nursing Process (ADPIE)

• Sequential Framework:

  • The nursing process is a structured, five-step clinical decision-making tool used to identify patient health problems, deliver targeted care, and evaluate outcomes.

  • The core steps follow the acronym ADPIE:

    • A - Assessment

    • D - Diagnosis (or Analysis)

    • P - Planning

    • I - Implementation

    • E - Evaluation

  • The framework serves as the standard methodology for solving clinical problems and answering nursing examination questions.

• Evolving Focus on Clinical Judgment:

  • Regulatory bodies, such as the Alabama Board of Nursing, are shifting emphasis toward integrating clinical judgment skills directly into the ADPIE structure.

  • While ADPIE remains the foundational process, emphasis is placed on immediate clinical decision-making in emergency situations.

  • In acute situations (e.g., a patient coding), the process transitions into immediate clinical action rather than a rigid step-by-step review.

Data Collection and Health Assessment

• Assessment Overview:

  • Assessment is the initial, continuous, and systematic collection of patient data throughout a facility stay.

  • In examination questions, assessment is always the mandatory first step before executing interventions.

  • Broad assessment targets include vital signs, heart sounds, lung sounds, surgical dressings, cough characteristics, and sudden changes in clinical condition.

• Information Sources:

  • Direct patient statements regarding their feelings, symptoms, or discomfort.

  • Physical nursing assessment findings.

  • Review of electronic medical records (EMR).

• Data Types:

  • Objective Data: Measurable, verifiable clinical facts that remain unaltered by personal feelings or perceptions.

    • Laboratory values.

    • Vital signs (e.g., blood pressure, heart rate, temperature, respiratory rate).

    • Physical assessment findings (e.g., presence of a barrel chest, nail bed color, lung auscultation).

  • Subjective Data: Information reported directly by the patient regarding personal feelings, perceptions, or symptoms.

    • Pain scores.

    • Reports of nausea, numbness, or gas.

    • Statements regarding emotional distress or anxiety.

• Types of Nursing Assessments:

  • Initial Admission Assessment: Comprehensive baseline evaluation completed upon admission to a facility.

  • Full Head-to-Toe Assessment: Systematic physical check covering all major body systems.

  • Focused Assessment: Targeted evaluation centered on a specific body system (e.g., abdominal or respiratory); used primarily in specialty units or during acute deterioration.

• Data Clustering:

  • Nurses organize collected assessment data into clusters to identify underlying problems.

  • Example Cluster: A patient presenting with a distended abdomen, fever, cough, thick sputum, gas, and hard passed stool requires data synthesis to differentiate between respiratory pathology (cough, thick sputum, fever) and gastrointestinal/abdominal pathology (distended abdomen, gas, hard stool, bowel blockage, or constipation).

Nursing Diagnoses vs. Medical Diagnoses

• Scope of Practice Differences:

  • Medical Diagnosis:

    • Identifies a specific disease process or medical condition.

    • Must be formally established by a physician or an Advanced Practice Registered Nurse (APRN).

    • Takes clinical priority over nursing diagnoses.

  • Nursing Diagnosis / Analysis:

    • Identifies the patient's physical, emotional, or physiological response to a health condition or life process.

    • Formulated by registered nurses to direct independent nursing interventions.

    • Modern Electronic Health Record (EHR) systems automatically suggest nursing diagnoses based on documented objective/subjective assessment data.

    • Standardized care plans and concept maps (visual representations with a core problem surrounded by descriptive details) are formulated using resources such as NANDA-I guidelines or digital resources.

• Diagnostic Categories:

  • Actual Diagnosis: Addresses an active, currently existing patient problem.

  • Potential / Risk Diagnosis: Identifies clinical conditions the patient has a high probability of developing.

• Common Standardized Nursing Diagnoses:

  • Impaired Gas Exchange (or Altered Gas Exchange): Assigned when patients present with shortness of breath, hypoxia, or ineffective breathing patterns.

  • Risk for Falls: High-frequency diagnosis applicable to elderly patients, post-surgical patients, or any individual receiving new sedating medications/hypnotics causing confusion or drowsiness.

  • Impaired Skin Integrity (or Risk for Impaired Skin Integrity): Assigned to patients with surgical wounds, immobility, or tissue exposure to moisture from urinary or bowel incontinence.

Formulating SMART Patient Goals

• SMART Goal Criteria:

  • S - Specific: Plainly states the exact patient outcome expected.

  • M - Measurable: Includes quantifiable parameters (e.g., specific vital sign values or pain scale numbers).

  • A - Attainable: Achievable given the patient's medical condition and baseline abilities.

  • R - Realistic: Practical target appropriate for the care setting and patient capabilities.

  • T - Timely: Assigned a clear time boundary for re-evaluation.

• Clinical Realism in Goal Setting:

  • Unrealistic Goal: Expecting a patient with paralysis secondary to a swimming pool spinal injury to walk to the bathroom within $2\,\text{days}$ during a $2\,\text{week}$ hospital stay prior to acute rehabilitation.

  • Appropriate Goal Modifications: Setting short-term and long-term goals that adapt dynamically as the patient's clinical status changes or recovers.

Clinical Application Scenarios

• Scenario 1: Respiratory Distress (Ms. Smith):

  • Assessment:

    • Subjective: Patient states, "I feel like I can't catch my breath."

    • Objective: Respiratory rate of $30\,\text{breaths/min}$, baseline $O_2$ saturation of $88\%$ (or $89\%$ documented), medical diagnosis of pneumonia.

  • Diagnosis / Analysis:

    • Nursing Diagnosis: Impaired Gas Exchange related to pneumonia.

    • Pathophysiological effect: Inability to breathe generates anxiety, which increases respiratory rate and worsens gas exchange impairment.

  • Planning (SMART Goal):

    • The patient will maintain an $O_2$ saturation of at least $94\%$ on supplemental oxygen within the designated care shift.

  • Implementation:

    • Positioning: Immediately adjust bed to High Fowler's position at a $90^\circ$ angle to maximize lung expansion.

    • Oxygen Therapy: Administer supplemental oxygen at $2\,\text{L}$ per protocol. (Note: Oxygen is legally classified as a medication requiring a physician's order; standard PRN standing orders allow immediate initiation of $2\,\text{L}$, followed by prompt physician notification).

    • Patient Coaching: Instruct patient on deep breathing, coughing exercises, and relaxation techniques to lessen anxiety.

    • Monitoring & Interdisciplinary Care: Continuously monitor respiratory status and coordinate with Respiratory Therapy.

  • Evaluation:

    • Reassess oxygen saturation. Value is recorded at $95\%$.

    • Conclusion: Goal met ($95\% \ge 94\%$); document improvement in EHR.

• Scenario 2: Post-Surgical Acute Pain Management:

  • Assessment: Patient reports acute post-surgical incision pain rated at $8/10$ on the pain scale.

  • Diagnosis: Acute Pain related to surgical tissue trauma.

  • Planning:

    • Unrealistic Goal: Pain reduction to $0/10$ within $30\,\text{minutes}$ post-surgery.

    • SMART Goal: Pain scale reduction to $3/10$ or lower within $1\,\text{hour}$ of intervention.

  • Implementation: Administer prescribed analgesic pain medication as ordered.

  • Evaluation:

    • Reassess pain score $30\,\text{minutes}$ post-administration.

    • Met Outcome: Pain reduced to $2/10$ ($2/10 \le 3/10$); document effective response.

    • Unmet Outcome Comparison: If pain score remained at $4/10$ an hour post-administration (e.g., after giving Tylenol), intervention is deemed ineffective, requiring physician notification for revised medication orders.

• Scenario 3: Elevated Blood Pressure Intervention:

  • Assessment: Measure baseline elevated blood pressure.

  • Implementation: Administer prescribed antihypertensive medication.

  • Evaluation: Recheck blood pressure $30\,\text{minutes}$ post-administration to confirm therapeutic reduction.

Prioritization Frameworks for Clinical Decision-Making

• Prioritization Hierarchy:

  1. Airway, Breathing, Circulation (ABCs): Respiratory and airway issues almost always take immediate clinical precedence over other concerns.

  2. Safety and Risk Mitigation: Fall prevention and injury protection.

  3. Acute vs. Chronic Problems:

     • Acute Issues: New-onset problems require immediate action.

     • Chronic Issues: Pre-existing baseline conditions (e.g., chronic back pain common among healthcare workers) are secondary to acute changes.

  4. Unstable vs. Stable: Unstable patient states take priority over stable clinical presentations.

  5. Actual vs. Risk Problems: Active physical issues take precedence over potential "risk for" diagnoses.

• Core Decision Question:

  • When prioritizing care, continually evaluate: "What is the greatest immediate threat to the patient's life?"
