Cranial and Dorsal Cavities

The cranial cavity is the specific space inside the skull which houses the brain. It is part of the dorsal cavity that is divided into:

  • Cranial cavity (houses the brain)
  • Spinal cavity (houses the spinal cord)

Legal Terminology in Healthcare

Crime Classifications

A crime punishable by a fine or imprisonment for less than one year is known as a misdemeanor, which is less serious than a felony.

Professional Negligence

Professional negligence is commonly known as malpractice in medical contexts, referring to the failure to exercise appropriate professional care.

Patient Confidentiality and Legal Disclosure

  • Confidentiality is paramount for assistive personnel, and it is essential to maintain it during daily routines in medical settings.
  • Information can only be released from a patient’s records under specific circumstances such as:
    • A court subpoena requesting the information.
    • A signed release by the patient.

Body Cavity Overview

Thoracic Cavity

  • The thoracic cavity contains critical organs including the heart, lungs, esophagus, and trachea.

Dorsal Cavity

  • The dorsal cavity is located at the back of the body and includes both the cranial cavity and spinal cavity.

Sterilization and Sanitization Processes

Sanitization and Disinfection

  • Sanitization involves scrubbing instruments with special brushes and detergents to remove contaminants like blood and mucous.
  • Disinfection is the process that destroys most microorganisms but not all; it often involves wiping or soaking methods.
  • Sterilization is required for supplies coming in contact with internal body tissues or open wounds and usually uses an autoclave or a chemical cold process.

Gathering and Documenting Patient Information

Subjective vs. Objective Data

  • Subjective data is obtained from conversations with the patient and includes complaints such as dizziness.
  • Objective data is measurable and observable, like a swollen or bruised eye during a physical examination.

Vital Signs

The vital signs must also take patient symptoms into account, including subjective complaints such as dizziness or pain. Standard precautions must be observed during examinations to minimize disease risk; for example, wearing PPE and providing space.

Medical Terminology and Charting

Charting Practices

The six C's of charting include:

  • Client's words
  • Clarity
  • Completeness
  • Conciseness
  • Chronological order
  • Confidentiality

Suture Sizes

Suture materials vary in thickness; the thickest listed is 0-0, which is larger than 5-0 or 7-0.

Body Planes and Positions

Body Planes

  • The sagittal plane divides the body into left and right portions.
  • The transverse plane divides the body into upper and lower sections.

Examination Positions

The Sims position is used for rectal examinations, involving the patient lying on their left side with the left leg flexed.

Maintaining Medical Asepsis

Hand Hygiene

Proper hand hygiene remains the most effective method for maintaining medical asepsis, emphasizing the importance of washing hands before and after patient contact.

Heart and Respiratory Terminology

Cardiac Terms

  • Cardiac output refers to the total amount of blood pumped out of the heart in one minute.
  • The average normal heart rate is about 72 beats per minute.

Respiratory Terms

  • Hyperpnea describes abnormally rapid or deep labored breathing, indicating a possible respiratory issue.

Infection Control Principles

Chain of Infection

The chain of infection outlines how infections are transmitted and involves the pathogen, host, reservoir, and means of transmission.

Isolation Precautions

Precautions such as airborne, droplet, and contact isolation are vital to prevent the spread of specific diseases, such as tuberculosis.

Legal and Ethical Implications in Healthcare

Negligence in Healthcare

Negligence occurs when a healthcare practitioner fails to exercise ordinary care, which can include actions like failing to report significant changes in a patient's condition or misidentifying a patient, leading to injury.

Civil Law in Healthcare

Civil law relates to legal actions between private parties. Actions like unauthorized blood draws can lead to charges of assault and battery due to causing bodily harm.

  • PT stands for Prothrombin Time, a coagulation study essential for assessing blood coagulation.

Financial Terminology

  • Assets are items of value owned by a practice.
  • The term accounts receivable refers to money owed to the practice for services rendered but not yet collected.
