Introduction to Medical-Surgical Nursing  Definition: The practice of nursing that focuses on the care of adults with acute and chronic illnesses across the lifespan, often in hospital settings, but also in ambulatory care, community health, and long-term care. It involves integrating knowledge from various fields (pharmacology, pathophysiology, psychology) to provide holistic, patient-centered care.  Role and Scope of the Medical-Surgical Nurse: o Care Provider: Direct patient care, assessment, planning, implementing, and evaluating nursing interventions. o Advocate: Protecting patient rights and ensuring their needs are met. o Educator: Providing health teaching to patients and families regarding illness, medications, procedures, and self-care. o Communicator: Effective communication with patients, families, and the interprofessional healthcare team. o Manager/Coordinator of Care: Prioritizing care, delegating tasks appropriately, coordinating services. o Researcher: Participating in evidence-based practice and contributing to nursing knowledge.  Interprofessional Collaboration: o Definition: Working with other healthcare professionals (physicians, pharmacists, dietitians, physical therapists, social workers, etc.) to achieve optimal patient outcomes. o Key Principles: Mutual respect, clear communication, shared decision-making, understanding of each team member's role.  Ethical and Legal Considerations in Nursing Practice: o Ethics:  Autonomy: Patient's right to make decisions about their own care.  Beneficence: Doing good for the patient.  Non-maleficence: Avoiding harm.  Justice: Fair and equitable distribution of resources and care.  Fidelity: Keeping promises.  Veracity: Telling the truth.  Confidentiality: Protecting patient information (e.g., HIPAA in the US). o Legal:  Scope of Practice: Defined by nurse practice acts in each state/country.  Standards of Care: What a reasonably prudent nurse would do in similar circumstances.  Informed Consent: Patient must be given adequate information about treatment options, risks, benefits, and alternatives before agreeing to a procedure or treatment. Nurse's role is to witness the patient's signature and ensure they appear to understand, not to provide the primary explanation.  Patient Rights: Right to privacy, respectful care, information, refusal of treatment, etc.  Documentation: Legal record of care; must be accurate, timely, factual, and complete.  Malpractice/Negligence: Failure to act as a reasonably prudent nurse, resulting in patient harm.  Quality and Safety in Nursing (e.g., QSEN Competencies, Patient Safety Initiatives): o QSEN (Quality and Safety Education for Nurses) Competencies:  Patient-Centered Care  Teamwork and Collaboration  Evidence-Based Practice (EBP)  Quality Improvement (QI)  Safety  Informatics o Patient Safety Initiatives:  Medication reconciliation  Hand hygiene  Fall prevention  Prevention of healthcare-associated infections (HAIs)  Time-outs before procedures  Use of technology (e.g., bar-code scanning for medication administration) II. Health Assessment and Clinical Judgment  Comprehensive Health History Taking: o Biographical Data: Name, age, gender, occupation, etc. o Chief Complaint (CC): Reason for seeking care, in patient's own words. o History of Present Illness (HPI): PQRST (Provoking/Palliating factors, Quality, Region/Radiation, Severity, Timing) or OLDCARTS (Onset, Location, Duration, Characteristics, Aggravating factors, Relieving factors, Treatment, Severity). o Past Medical History (PMH): Childhood illnesses, adult illnesses, hospitalizations, surgeries, accidents, immunizations, allergies, current medications. o Family History (FH): Genetic predispositions, communicable diseases. o Social History (SH): Lifestyle (smoking, alcohol, drug use), diet, exercise, support systems, spiritual/cultural beliefs. o Review of Systems (ROS): Subjective data reported by the patient for each body system.  Physical Assessment Techniques: o Inspection: Careful observation of appearance, symmetry, movement, skin characteristics. o Palpation: Using touch to assess texture, temperature, moisture, masses, tenderness, organ size. o Percussion: Tapping on body surfaces to produce sounds (resonance, dullness, flatness, tympany) that indicate underlying tissue density. o Auscultation: Listening with a stethoscope to internal body sounds (heart, lung, bowel sounds).  Development of Clinical Judgment and Critical Thinking: o Clinical Judgment: The observed outcome of critical thinking and decision-making. It's an iterative process of noticing, interpreting, responding, and reflecting in clinical practice. o Critical Thinking: A systematic process of assessing, analyzing, and synthesizing information to solve problems or make decisions. Essential for effective nursing care. o Nursing Process (ADPIE):  Assessment: Gathering subjective and objective data.  Diagnosis: Analyzing data to identify patient problems (nursing diagnoses).  Planning: Setting patient goals and expected outcomes, developing interventions.  Implementation: Carrying out interventions.  Evaluation: Determining if goals were met and revising the plan as needed. III. Pharmacology Review (General Principles)  Principles of Pharmacokinetics: How the body acts on the drug. o Absorption: Movement of drug from site of administration into bloodstream. Factors: route, drug form, blood flow, GI motility, food. o Distribution: Movement of drug from bloodstream to tissues and organs. Factors: blood flow, protein binding, blood-brain barrier. o Metabolism (Biotransformation): Chemical alteration of drug by body, primarily in the liver. Converts drugs into active/inactive metabolites, or more water-soluble forms for excretion. First-pass effect. o Excretion: Elimination of drugs from the body, primarily by kidneys (urine), also liver (bile), lungs, skin, sweat, breast milk.  Principles of Pharmacodynamics: How the drug acts on the body. o Mechanism of Action: How a drug produces its therapeutic effect (e.g., binding to receptors, inhibiting enzymes). o Therapeutic Effect: The desired primary effect. o Side Effects: Undesirable, often predictable, mild responses. o Adverse Effects: More severe, harmful, unintended responses. o Toxic Effects: Harmful effects resulting from drug accumulation above therapeutic level. o Drug Interactions: Synergistic, antagonistic, additive effects.  Medication Administration Principles and Safety: o Five Rights of Medication Administration (plus additional "rights"): 1. Right Patient 2. Right Drug 3. Right Dose 4. Right Route 5. Right Time Additional Rights: Right Documentation, Right Reason, Right Assessment, Right Response/Evaluation, Right to Refuse. o Dosage Calculations: Essential skill to ensure accurate medication delivery. o Safe Handling and Storage: Especially for controlled substances and hazardous medications. o Patient Education: Explaining drug purpose, dose, schedule, side effects to watch for. o Medication Reconciliation: Process of comparing a patient's medication orders to all of the medications that the patient has been taking. Done at admission, transfer, and discharge. IV. Pain Management  Physiology of Pain: o Transduction: Noxious stimuli convert to electrical energy at the peripheral nerve endings. o Transmission: Pain impulse moves from periphery to spinal cord, then to the brain. o Perception: Conscious awareness of pain in the brain. o Modulation: Descending pain pathways from the brainstem
