Medical Assisting Comprehensive Review Flashcards

Psychology and Lifespan Development

• Foundational Terminology:

  • Psychology: The study of mind and behavior.
  • Psychologist: A healthcare professional who evaluates human behavior.
  • Psychiatrist: A licensed physician ($\text{MD}$) who assesses behavior, prescribes medications, and provides ongoing psychotherapy.

• Growth and Lifespan Development:

  • Physical Growth: Refers to physical growth from infancy to adulthood and the accompanying physiological changes.
  • Developmental Domains: Encompasses emotional, physiological, mental, social, interactive, spiritual, and physical changes across the human lifespan.

• Erikson's Theory of Psychosocial Development:

  • States that the human life cycle consists of eight distinct developmental stages from birth to death, each defined by a central psychosocial conflict:
    • Infancy ($0$ to $18\text{ months}$): Basic conflict is Trust vs. Mistrust. Important events center on Feeding/Comfort. Key question: Is my world safe? Outcome: Children develop trust when caregivers provide reliability, care, and affection; a lack leads to mistrust.
    • Early Childhood ($2$ to $3\text{ years}$): Basic conflict is Autonomy vs. Shame and Doubt. Important events center on Toilet Training/Dressing. Key question: Can I do things by myself or need I always rely on others? Outcome: Children need to develop personal control over physical skills and independence. Success leads to autonomy; failure results in shame and doubt.
    • Preschool ($3$ to $5\text{ years}$): Basic conflict is Initiative vs. Guilt. Important events center on Exploration/Play. Key question: Am I good or bad? Outcome: Children assert control and power over the environment. Success leads to purpose; overexertion of power brings disapproval and guilt.
    • School Age ($6$ to $11\text{ years}$): Basic conflict is Industry vs. Inferiority. Important events center on School/Activities. Key question: How can I be good? Outcome: Coping with new social and academic demands. Success leads to competence; failure results in feelings of inferiority.
    • Adolescence ($12$ to $18\text{ years}$): Basic conflict is Identity vs. Role Confusion. Important events center on Social Relationships/Identity. Key question: Who am I and where am I going? Outcome: Teens develop a sense of self and personal identity. Success leads to staying true to oneself; failure leads to role confusion and a weak sense of self.
    • Young Adult ($19$ to $40\text{ years}$): Basic conflict is Intimacy vs. Isolation. Important events center on Intimate Relationships. Key question: Am I loved and wanted? Outcome: Forming intimate, loving relationships. Success leads to strong relationships; failure results in loneliness and isolation.
    • Middle Adulthood ($40$ to $65\text{ years}$): Basic conflict is Generativity vs. Stagnation. Important events center on Work and Parenthood. Key question: Will I provide something of real value? Outcome: Adults create or nurture things that outlast them (having children, positive community impact). Success leads to usefulness and accomplishment; failure leads to shallow involvement.
    • Maturity ($65\text{ years}$ to death): Basic conflict is Ego Identity vs. Despair. Important events center on Reflection on life. Key question: Have I lived a full life? Outcome: Looking back on life with fulfillment. Success leads to wisdom; failure results in regret, bitterness, and despair.

• Maslow's Hierarchy of Needs:
  • Developed by Abraham Maslow on the premise that human needs range from basic survival to complex self-fulfillment.
  • Structured as a five-level pyramid where lower-level basic needs must be met before higher-level psychological and self-fulfillment needs can be achieved:
    1. Biological & Physiological Needs (Basic Needs): Food, sleep, water, shelter.
    2. Safety Needs (Basic Needs): Security, health, finances, physical safety.
    3. Love / Belonging Needs (Psychological Needs): Friendship, intimacy, family, emotional connections.
    4. Esteem Needs (Psychological Needs): Respect, status, recognition, internal strength, self-esteem.
    5. Self-Actualization Needs (Self-Fulfillment Needs): Meeting one's full potential in life (unique to every individual).

• Gerontology and End-of-Life Care:
  • Gerontology: The scientific study of aging and the elderly.
  • Geriatric: Term applied to individuals age $65\text{ years}$ and older, a period when body systems undergo progressive decline.
  • Terminal Illness: An incurable disease or condition that ultimately results in death.
  • Dr. Elisabeth Kübler-Ross's Five Stages of Grief:
    • Denial: Rejection of reality or insisting a medical diagnosis is an error.
    • Anger: Hostility directed outward at family, healthcare workers, or oneself when denial can no longer be sustained.
    • Bargaining: Seeking extra time by making promises, frequently involving religious or spiritual vows.
    • Depression: Quiet withdrawal, verbalization of regret, and intense sadness over impending loss.
    • Acceptance: Final stage marked by acknowledgment of mortality, settling personal affairs, and preparing family members.

Patient Communication and Customer Service

• Modes of Communication:

  • Communication: The process of exchanging information, ideas, and messages.
  • Verbal Communication: The use of spoken or written language and words. Spoken verbal communication occurs face-to-face, over the phone, individually, or in groups, and is the most frequently utilized form.
  • Tone of Voice: Conveys emotional state beyond literal word choices. Patients detect volume, rate, and pitch, interpreting them as fear, agitation, calmness, or confidence.
  • Lay Terms: Plain, everyday language used to clarify clinical terms for patients (e.g., substituting "lower back" for "lumbar"). Over-simplification that patronizes the patient must be avoided.
  • Therapeutic Communication: Patient-centered communication that treats the individual as a whole person.
  • Questioning Techniques:
    • Open-Ended Questions: Require detailed responses rather than one-word answers (e.g., "What happened?" or "How do you feel?"). Asking "why" questions should be avoided as it induces defensiveness.
    • Closed / Direct Questions: Require specific, concise answers, usually "yes" or "no" (e.g., "Are you having difficulty breathing?" or "When did you last eat something?").
  • Written Communication: Includes written messages, lab/test results, medical chart notes, clinic policies, and patient educational leaflets.
  • Nonverbal Communication: Body language, eye contact, facial expressions, physical appearance, posture, touch, and personal space/proximity.
  • Internal vs. External Communication: Internal occurs within the practice (face-to-face, internal email, phone, fax); external occurs between the practice and outside entities or business partners.
