Professionalism, Legal, and Ethical Practice for the EMR
Knowing Your Scope and Your Duty
The EMR works inside a defined scope of practice and a legal framework. Understand three ideas that questions love to test: consent, negligence, and confidentiality. Valid consent requires capacity, information, and voluntariness. A patient who is unconscious, or whose condition threatens life or limb, is treated under the doctrine of implied consent. Minors and patients lacking capacity usually require a substitute decision-maker, but a true emergency still justifies immediate treatment.
Negligence has four elements: a duty to act, a breach of the standard of care, causation, and damages. All four must be present; a question describing a bad outcome without a breach is not negligence. Abandonment occurs when care is discontinued without a proper handover or equal-or-better transfer of responsibility.
Traps to Watch
- Confusing ethical duties (beneficence, non-maleficence, autonomy, justice) with legal ones. Ethical obligations are broader; not every ethical lapse is a legal one.
- Assuming a signed form replaces the need to explain care. Consent must be informed.
- Mistaking advance directives for a blanket order to withhold all care. Comfort measures and reassessment usually continue.
- Ignoring the duty to report suspected abuse, neglect, or certain communicable diseases, which is a legal obligation in most jurisdictions.
Worked Example
A competent adult with crushing chest pain refuses transport after you explain the risks. The correct approach is to document the informed refusal, ensure the patient is safe, and advise them to call again if symptoms worsen. You do not transport against their will, and you do not simply leave without documentation. That example shows the balance between autonomy and duty of care.
Rule of Thumb
If the patient can understand, decide, and communicate, you must respect the decision; if they cannot, treat and document.
Airway, Breathing, and Circulation Assessment
Primary Survey Priorities
The ABCs are the backbone of every EMR assessment. Start with a rapid primary survey: is the airway open, is breathing adequate, is circulation present? For an unresponsive patient, open the airway with a head-tilt chin-lift unless a spinal injury is suspected, in which case use a jaw thrust. Look, listen, and feel for breathing while simultaneously checking for a pulse and major bleeding.
Ventilation and Oxygenation
Recognize inadequate breathing (rate too slow or too fast, shallow depth, poor chest rise, cyanosis, or absent air movement). Positive-pressure ventilation with a bag-valve mask is indicated when breathing is inadequate. Supplemental oxygen is used for hypoxemia or suspected shock. Questions often test the difference between respiratory distress (patient is working to breathe but moving air) and respiratory failure (inadequate ventilation, altered mental status, exhaustion). Failure needs ventilation support, not just oxygen.
Circulation and Shock
Assess pulse, skin color, temperature, moisture, and capillary refill. Shock is inadequate tissue perfusion; early signs include anxiety, pale cool clammy skin, and a rapid weak pulse. Control life-threatening external bleeding with direct pressure, then a tourniquet if pressure fails on an extremity.
Traps
- Treating a patient with a normal oxygen saturation but poor ventilation as "fine." Saturation can look normal while the patient is tiring.
- Forgetting to reassess after every intervention.
- Applying a tourniquet without noting the time.
Worked Example
A patient has a respiratory rate of 6, shallow breaths, and drowsiness. Oxygen alone is not enough; the correct action is to assist ventilation with a bag-valve mask and reassess.
Patient Assessment and History Taking
The Assessment Sequence
Beyond the primary survey, the EMR performs a focused history and physical exam. Use a consistent structure: scene size-up, primary survey, history, secondary survey, and ongoing reassessment. The SAMPLE history covers Signs and symptoms, Allergies, Medications, Past medical history, Last oral intake, and Events leading to the illness or injury. The OPQRST framework characterizes pain: Onset, Provocation, Quality, Radiation, Severity, and Time.
Scene Size-Up
Before touching the patient, assess hazards, the number of patients, the mechanism of injury or nature of illness, and needed resources. A question describing an unsafe scene expects you to stage safely and call for help, not to rush in.
Traps to Watch
- Skipping the history because the physical findings seem obvious.
- Confusing signs (observed) with symptoms (reported).
- Accepting a patient's self-diagnosis without exploring the actual complaint.
- Forgetting to reassess after treatment or during transport; trends matter more than single values.
Worked Example
A patient reports chest pain that began while resting, radiates to the left arm, and is rated 8/10. Using OPQRST, you note onset at rest, no clear provocation, pressure-like quality, radiation to the arm, severity 8/10, and duration 20 minutes. That structured detail guides your report and your urgency.
Rule of Thumb
Treat the patient, not the monitor. A calm, systematic history often reveals the true problem faster than any device.
Medical Emergencies and Pharmacology Basics
Recognizing Common Medical Emergencies
The EMR must recognize presentations of cardiac, respiratory, neurological, diabetic, and allergic emergencies. Key patterns: cardiac chest pain (pressure, radiation, sweating, nausea), stroke (sudden facial droop, arm weakness, speech difficulty, time of onset), hypoglycemia (altered mental status, sweating, hunger, confusion), and anaphylaxis (rapid onset, hives, swelling, difficulty breathing, hypotension).
Medications in Scope
EMRs may assist with or administer a limited set of medications depending on jurisdiction, commonly aspirin for suspected cardiac chest pain, epinephrine auto-injectors for anaphylaxis, and glucose for hypoglycemia. Know the indication, contraindication, dose route, and expected effect for each. Aspirin is contraindicated in true allergy and in active gastrointestinal bleeding. Epinephrine is given intramuscularly for anaphylaxis; antihistamines alone do not treat airway swelling.
Traps to Watch
- Giving aspirin to a patient who reports an aspirin allergy or recent GI bleed.
- Treating stroke symptoms with glucose without checking blood glucose first, or delaying transport.
- Assuming an auto-injector replaces transport; it does not.
- Confusing hyperglycemia (gradual onset, dehydration, fruity breath) with hypoglycemia (sudden, sweaty, confused).
Worked Example
A patient with known diabetes is confused and sweaty, and a glucose reading is low. If the patient can swallow and protect the airway, give oral glucose and reassess; if not, arrange advanced care. Document the reading before and after.
Rule of Thumb
Match the medication to the presentation, check allergies first, and always reassess the effect.
Trauma and Environmental Emergencies
Mechanism and Injury Patterns
Trauma care begins with the mechanism of injury. Blunt versus penetrating, energy involved, and patient age shape your suspicion. Follow the primary survey with a secondary survey that examines head, neck, chest, abdomen, pelvis, extremities, and back. Control external bleeding with direct pressure first; use a tourniquet for life-threatening extremity bleeding when pressure fails.
Head, Spine, and Chest
Suspect spinal injury with high-energy mechanisms, altered mental status, or neurological deficits. Immobilize as your protocol directs while maintaining the airway. For chest injury, watch for respiratory distress, absent breath sounds on one side, and signs of tension physiology; these require rapid transport and advanced care.
Environmental Emergencies
For heat illness, distinguish heat exhaustion (sweating, weakness, normal mental status) from heat stroke (altered mental status, hot skin, a medical emergency). For hypothermia, handle the patient gently, remove wet clothing, insulate, and avoid rough movement. For frostbite, do not rub the tissue; protect and warm gradually.
Traps to Watch
- Rubbing frostbitten tissue or applying direct high heat.
- Missing shock in a trauma patient because the blood pressure is still normal; early shock shows a narrow pulse pressure and rising heart rate.
- Delaying transport to complete a thorough secondary survey in an unstable patient.
Worked Example
A fall from height leaves a patient confused with a deformed thigh and heavy bleeding. Control bleeding, immobilize, support the airway, and transport rapidly, reassessing en route.
Special Populations and Emergency Childbirth
Adapting Care
Special populations require adjusted assessment and technique. For pediatric patients, use a length-based or weight-based system for equipment and dosing, and remember that children compensate well then deteriorate suddenly. For older adults, account for medications, chronic disease, and reduced reserve; a normal blood pressure may represent hypotension for them. For pregnant patients, remember that the uterus can compress the inferior vena cava; position the patient on her left side or manually displace the uterus. For patients with disabilities, communicate directly with the patient and ask about their usual baseline.
Emergency Childbirth
Childbirth is usually a natural process. Prepare a clean area, support the mother, and control the delivery of the head. Check for a nuchal cord and slip it over the head if possible. After delivery, dry and warm the newborn, stimulate breathing, and assess. Clamp and cut the cord only per protocol, and watch for delivery of the placenta. If the newborn does not breathe after stimulation, begin newborn resuscitation per your training.
Traps to Watch
- Pulling on the baby or the cord.
- Letting the newborn get cold; heat loss is a major risk.
- Assuming a pregnant patient's abdominal pain is obstetric when it may be another emergency.
- Using adult dosing or equipment for a child.
Worked Example
A mother delivers a baby who is not breathing. Dry and stimulate the newborn, position the airway, and begin ventilation per protocol while keeping the baby warm.
Operations, Communication, and Documentation
Safe Operations
The EMR works within an emergency response system. Understand the chain of survival, dispatch information, scene safety, and the roles of responders. Communication is a core skill: use clear, closed-loop communication with your team and structured radio reports (identify yourself, give location, patient status, and needs). A structured handover report, often using a standard format, ensures continuity of care.
Documentation
Documentation is a legal record. Record objective findings, interventions, times, and the patient's response. Write in a factual, chronological, and professional manner. Avoid speculation, blame, or subjective language. Correct errors properly rather than erasing them. Document refusals, including the risks explained and the patient's understanding.
Traps to Watch
- Writing opinions or conclusions rather than observations.
- Omitting times of interventions and reassessments.
- Failing to document an informed refusal and the advice given.
- Giving unclear radio reports that omit patient status or needed resources.
Worked Example
A radio report should include your unit, location, patient age and sex, chief complaint, vital signs, interventions performed, and estimated time of arrival. That structure lets the receiving team prepare.
Rule of Thumb
If it is not documented, it did not happen; record what you saw, did, and observed afterward.
