Medical Emergencies - Chapter 9 Review

Overview

  • Focus on medical emergencies as per Chapter 9 of the Torres Patient Care Book.
  • Enables students to:
    • Assess neurological and cognitive functioning.
    • Classify shock and describe the shock continuum.
    • Recognize and respond to various medical emergencies.

Key Topics Covered

Neurological and Cognitive Assessment

  • Assess upon patient admission for a diagnostic procedure to establish a baseline.
  • Observe for changes in consciousness and report.
  • Use the Glasgow Coma Scale for assessment.

Emergency Procedures in Imaging Departments

  • Immediate action in emergencies: call hospital emergency team (code blue).
  • Know emergency team's contact and location.
  • Emergency carts (crash carts) available with essential medications and equipment.

Shock

  • Types of Shock:
    • Hypovolemic Shock: Due to blood or fluid loss.
    • Cardiogenic Shock: Resulting from cardiac disorders.
    • Distributive Shock: Involving blood pooling in peripheral vessels; includes neurogenic, septic, and anaphylactic shock.

Shock Continuum

  • Initial Stage: Increased heart rate.
  • Compensatory Stage: Redirecting blood from non-essential organs.
  • Progressive Stage: Decreased perfusion and worsening symptoms.
  • Irreversible Stage: Organ damage and failure.

Anaphylactic Shock

  • Common in radiographic imaging due to iodine contrast media.
  • Symptoms: Nasal congestion, itching, hives, breathing difficulties, severe reactions.
  • Management: Immediate stop of infusion, inform radiologist, monitor vitals, and be prepared for CPR.

Pulmonary Embolism (PE)

  • Blockage in pulmonary arteries by clots.
  • High risk in hospitalized surgical patients.
  • Includes symptoms like chest pain, rapid heart rate.

Diabetes Mellitus

  • Types:
    • Type 1: Insulin-dependent, occurs in younger individuals.
    • Type 2: Most common, management includes lifestyle changes.
    • Gestational: Occurs during pregnancy.
  • Emergencies: Hypoglycemia, diabetic ketoacidosis, hyperosmolar hyperglycemic non-ketotic syndrome.

Cerebral Vascular Accident (Stroke)

  • Blockage or rupture of brain blood vessels.
  • Symptoms: Headache, weakness, vision impairment, speech difficulty.
  • Immediate response and intervention required.

Cardiac and Respiratory Emergencies

  • Cardiac Arrest: Heart stopping effectively; necessitates CPR and defibrillation.
  • Respiratory Arrest: Breathing ceases; requires immediate intervention.
  • Use of AEDs and maintaining CPR certification is critical.

Airway Obstructions

  • Can be partial or complete.
  • Response: Immediate help, abdominal thrusts, and ensure airway is clear.

Additional Considerations

  • Seizures: Stay with patient, do not restrain, note duration.
  • Syncope (Fainting): Supine position with legs elevated.
  • Other Conditions: Nausea, nosebleeds (epistaxis), vertigo, asthma.

Conclusion

  • Radiographers must be vigilant in recognizing and managing medical emergencies.
  • Awareness of emergency procedures and patient care standards is essential for effective intervention.
