Study Notes
Cardiology and Emergency Response
- Adult patient with a history of myocardial infarctions presents with chest pain, difficulty breathing, and pale, hot skin; symptoms may suggest pericarditis.
- First responders to a multi-casualty vehicle accident should request additional resources, including fire rescue and more ambulances, for appropriate care.
- A blunt force head injury may impair cranial nerves II, III, and IV, evident in the patient's abnormal pupillary reaction and inability to follow objects.
Shock and Physiological Responses
- Shock is characterized by hypoperfusion with distributive shock including anaphylactic reactions.
- Sympathetic response during traumatic shock is initiated by decreased perfusion and increased acidosis.
- The absolute refractory period on an ECG occurs during the Q-T interval, crucial for preventing arrhythmias.
Cardiovascular Interventions
- For unstable adult patients with supraventricular tachycardia, synchronized cardioversion should start at 50-100 joules if the rhythm is narrow complex and regular.
Neurological Considerations
- One-sided facial droop in adults may indicate Bell's palsy, signifying facial nerve involvement.
- Emancipated minors can consent to treatment; a 16-year-old claiming independence under court laws can be treated without parental consent.
Hyperkalemia Management
- In cases of severe hyperkalemia, high-dose nebulized albuterol and calcium chloride may be administered to manage the condition and stabilize cardiac function.
