Nursing Fundamentals

Dose Calculation

  • Understanding the principles of dosage calculations, including metric conversions and dosage forms.

  • Importance of accurate calculations to prevent medication errors.

  • Common formulas used in dose calculations, such as dimensional analysis and ratio-proportion methods.

  • Case study example: Calculating the correct dose for a pediatric patient based on weight.

  • Tools and resources for ensuring accurate dose calculations, including calculators and reference guides.

  • 1mg = 1000 mcg 1g = 1000 mg 1kg = 1000 g 1kg = 2.2 lbs

Medication Administration

  • the medication administration process, including the five rights: right patient, right drug, right dose, right route, right time.

  • Special considerations for administering medications via G-Tube including preparation and patient positioning.

  • interventions:

  • elevate the clients head of the bed to avoid aspiration

  • verify tube placement

  • Guidelines:

  • use liquid forms, if not available crush meds if appropriate

  • no sublingual meds

  • administer each med separately + do not mix meds with enteral feedings

  • flush tubing before and after 15-30 mL & flush with another 30-60 mL after instilling all meds

  • Safety protocols to follow during medication administration to minimize risks.

  • Case study example: Managing a patient with multiple medications and potential interactions.

  • Subcutaneous: Heparin/ Insulin (3/8 - 5/8 inch, 25-27 gauge needle or 28- 31 gauge insulin syringe - average size 45-90 angle - obese 90 angle

  • Intramuscular: needle size 18-25 gauge, 5/8-1.5 inch long, 90 angle, use a z-track method

  • Parental: use a tuberculin syringe solution less than 0.5 mL

  • Intradermal: fine-gauge needle 25-27 gauge, 5-15 angle, insert with the bevel up

Infection Control and Hygiene

  • Key principles of infection control, including hand hygiene, use of personal protective equipment (PPE), and sterilization techniques.

  • Understanding the chain of infection and strategies to break it.

  • Importance of maintaining hygiene in patient care to prevent healthcare-associated infections (HAIs).

  • Overview of sterile technique and its application in clinical settings.

  • Case study example: Managing a patient with a surgical wound and preventing infection.

  • Infection: risks- age (immature immune system, decrease in functions), impaired circulation and oxygenation

  • pus, pain, redness, fever chills, odor, increased pule/respirations, high WBC

  • Interventions- aseptic technique, optimal nutrition, adequate rest

Patient Assessment and Safety

Health Assessment Techniques

  • Differences between focused and comprehensive health assessments and when to use each.

  • Key components of a head-to-toe assessment, including vital signs, skin assessment, and neurological checks.

  • Techniques for conducting a thorough pain assessment, including the use of pain scales and patient interviews.

  • Importance of pulse assessment and understanding normal vs. abnormal findings.

  • Case study example: Assessing a patient with chronic pain and developing a care plan.

Prioritization and Delegation

  • Strategies for prioritizing patient care based on urgency and patient needs.

  • Understanding the role of delegation in nursing practice and when it is appropriate to delegate tasks.

  • do NOT delegate what you cannot EAT: evaluate, assess, and teach

  • you can delegate 2nd assessments, unstable patients

  • Five rights of Delegation:

  • task, circumstance, person, direction/communication, supervision/evaluation

  • Importance of collaboration with healthcare team members to ensure patient safety.

  • Ethical considerations in prioritization and delegation, including patient advocacy.

  • Prioritization:

  • safety, nursing process (ADPIE), patient needs, ABCs- airway, breathing, circulation, unstable, stable

  • assess first unless indicated

  • Case study example: Managing a busy unit and prioritizing care for multiple patients.

Professional Practice and Ethics

Professionalism and Advocacy

  • Definition of professionalism in nursing and its impact on patient care.

  • Key elements of patient advocacy and the nurse's role in supporting patients' rights and needs.

  • Importance of cultural competence in providing equitable care to diverse populations.

  • Case study example: Advocating for a patient with limited English proficiency.

Legal and Ethical Considerations

  • Overview of healthcare laws that impact nursing practice, including patient privacy and informed consent.

  • Responsibility- respect obligations

  • Accountability- setting out to accomplish the things you said you would do, willingness to accept responsibility for actions

  • Confidentiality- state of being kept secret or private

  • Autonomy- right to make one's own decisions

  • Beneficence- goodness for others without self interest

  • Fidelity- fulfillment of promises

  • Justice- fairness in delivery

  • Nonmaleficence- duty to do no harm

  • veracity- tell the truth

  • Negligence- failure to exercise appropriate care expected to be exercised in similar circumstances

  • Strategies for navigating ethical dilemmas in clinical practice.

  • Case study example: Addressing a conflict between patient autonomy and medical advice.

Pressure Ulcers/Wounds

serous drainage- watery and clear, lightly yellow

sanguineous drainage- thick and reddish, brighter drainage

serosanguineous drainage: both serum and blood, watery- pale and pink

purulent- pus

purosanguineous- pus and blood

dehiscence- partial or total rupture (seperation)

evisceration- protrusion of visceral organs - moist towel

Stage 1- intact, nonblanchable skin

Stage 2- partial thickness skin with exposed dermis, reddish-pinkish bed without slough, eschar, or granulation tissue, intact or ruptured blister

Stage 3- full-thickness skin loss, visible adipose tissue possible granulation and epibole, some slough/eschar present, no exposed muscle, tendons, ligaments, cartilage, or bones

Stage 4- full-thickness skin and tissue loss, skin/tissue loss with cartilage, bone, fascia, muscle, ligaments, or tendon exposed in wound. epibole, tunneling, and undermining

Unstageable- obscured, full-thickness skin and tissue loss, no determination of stage because of eschar or slough obscures the wound bed, depth is unknown

  • surgical wounds cannot be staged*

Interventions:

Adapting Health Assessment (Comprehensive vs Focused)

focused- detailed specific body systems or concern ex. abdominal pain or difficulty breathing

Comprehensive- covers a patients general status ex. patient history, physical exam, vital signs

Functional Ability

patients capacity to perform daily activities such as dressing, standing, and sitting, without assistance (measures physical, psychosocial, cognitive, and social abilities)

Interventions: pain management, exercise, early discharge

Clinical Judgment

  • process to analyze patient information, assess situations, make informed decisions by gathering data, questioning, and applying clinical knowledge

Sterile Technique

aseptic technique

  • prevention contamination and reduce risk of infection in a surgical or invasive procedure

hand hygiene, sterile field, donning sterile gloves

Elimination

factors:

age, diet (fiber requirement 25-38 g/day), fluids, physical activity, psychosocial factors, personal habits, positioning, pain, pregnancy, surgery/anesthesia, and meds

PT ed: regular BP monitoring, adhere to meds, lifestyle changes

PVD (pulmonary vascular disease)

A condition that affects the blood vessels in the lungs, making it harder for blood to flow properly. This can lead to breathing problems and reduced oxygen supply to the body.

  • Signs and Symptoms: May include symptoms like leg pain while walking that resolves with rest, coldness in lower leg or foot, sores or wounds on toes, feet, or legs that won't heal, and changes in color of the legs.

  • Risk Factors: Common risk factors include smoking, diabetes, obesity, high blood pressure, high cholesterol, and age.

    • Educate about lifestyle changes such as quitting smoking and maintaining a healthy diet.

    • Encourage regular exercise and foot care.

    • Monitor and manage blood pressure and glucose levels.

Culture

Collaboration in nursing is essential for providing comprehensive patient care. It involves working alongside other healthcare professionals to develop effective care plans. Key components include:

  • Interdisciplinary Teamwork: Engaging with doctors, pharmacists, social workers, and therapists to share knowledge and expertise.

  • Communication: Maintaining clear, consistent communication among team members to ensure patient safety and coordinated care.

  • Patient-Centered Care: Involving patients and their families in decision-making processes to respect their preferences and enhance their care experience.

  • Role Clarity: Understanding each team member's responsibilities and contributions to optimize team function.
