Emergency Nursing Vocabulary in English — 20 Essential Terms

Triage comes from the French word meaning to sort or select. In emergency nursing, it is the process of rapidly assessing every patient who arrives in the emergency department and assigning a priority category based on the severity of their condition. Patients who are critically ill or in immediate danger, such as those in cardiac arrest or with severe haemorrhage, are treated first. Those with minor injuries or illnesses that are not life-threatening wait longer. Triage ensures that limited staff and resources are used where they are needed most urgently.

Vital signs are the four basic measurements that reflect the essential functions keeping a patient alive: temperature, pulse rate, respiratory rate, and blood pressure. Many hospitals now add a fifth sign — oxygen saturation — measured with a pulse oximeter. Vital signs give nurses a rapid snapshot of whether a patient is stable, deteriorating, or improving. In emergency nursing, they are recorded at frequent intervals because even a small change in one measurement can indicate a serious underlying problem that requires immediate intervention.

Resuscitation is the broader term for all the actions taken to revive a patient whose heart or breathing has stopped, including chest compressions, rescue breaths, and the administration of drugs such as adrenaline. Defibrillation is one specific component of resuscitation: the delivery of a controlled electric shock to the heart to correct a chaotic, life-threatening rhythm such as ventricular fibrillation. Not all patients in cardiac arrest can be defibrillated; the shock is only effective when the heart is in a shockable rhythm. Nurses and paramedics are trained to use automated external defibrillators (AEDs) in these situations.

The Glasgow Coma Scale (GCS) is a neurological assessment tool originally developed in 1974 and still widely used today. It measures a patient's level of consciousness by scoring three areas: eye opening (1–4 points), verbal response (1–5 points), and motor response (1–6 points). The three scores are added together to give a total between 3 and 15. A score of 15 indicates a fully conscious patient, while a score of 3 indicates deep unconsciousness. Emergency nurses use the GCS on arrival and repeat it at regular intervals to detect any deterioration in neurological status, which might indicate a head injury, stroke, or other serious condition.

Sepsis is a medical emergency in which the body's immune response to an infection becomes dangerously overactive and begins to damage its own tissues and organs. It can develop rapidly and lead to septic shock and death if not treated within hours. Emergency nurses are trained to screen for sepsis using tools such as the National Early Warning Score (NEWS) and to recognise the classic warning signs: a very high or very low temperature, a fast heart rate, rapid breathing, low blood pressure, confusion, and reduced urine output. If sepsis is suspected, nurses initiate the sepsis bundle — a set of time-critical interventions including blood cultures, intravenous antibiotics, and fluid resuscitation — as quickly as possible.

Airway management encompasses all the techniques used to keep a patient's airway open so that oxygen can reach the lungs. In emergency nursing, this begins with simple positioning manoeuvres such as the head-tilt chin-lift and jaw thrust. Nurses may insert an oropharyngeal (Guedel) airway or nasopharyngeal airway to hold the airway open in an unconscious patient. If these measures are insufficient, the patient may require intubation, where a tube is passed through the mouth or nose into the trachea and connected to a mechanical ventilator. Maintaining a clear airway is the first step in every emergency assessment because without it, all other interventions are futile.

Anaphylaxis is a severe, rapidly developing allergic reaction that affects the whole body. It is triggered by allergens such as certain foods (particularly nuts), insect stings, latex, or medications such as antibiotics. The key features include swelling of the tongue and throat that can obstruct the airway, a sudden drop in blood pressure (anaphylactic shock), hives or flushing of the skin, and difficulty breathing. The first-line treatment is an injection of adrenaline (epinephrine), given intramuscularly into the outer thigh. Nurses also administer high-flow oxygen, intravenous fluids, antihistamines, and corticosteroids, and the patient is closely monitored in case symptoms return after the initial treatment.

A handover is the structured transfer of responsibility for a patient's care from one nurse or clinical team to another, typically at the end of a shift. An effective handover ensures that the incoming team has all the information they need to provide safe, continuous care without delay. In many hospitals, the SBAR framework is used: Situation (what is happening now), Background (relevant history), Assessment (what the nurse thinks the problem is), and Recommendation (what needs to happen next). Poor handovers are a significant cause of preventable errors in hospital care, which is why they are recognised as a patient safety priority by nursing regulators around the world.

Discharge planning is the process of preparing a patient to leave hospital safely. In the emergency department, it begins from the moment of admission because delays in planning lead to unnecessarily long hospital stays and poorer patient outcomes. It involves assessing whether the patient can manage at home or needs additional support, arranging follow-up appointments, referring to community services or social care if needed, and educating the patient about their diagnosis, medications, and warning signs that should prompt a return to hospital. Effective discharge planning requires close collaboration between nurses, doctors, social workers, and the patient's family.

The most effective approach combines contextual learning with regular practice. Start by grouping the words by clinical scenario: assessment words such as triage, GCS score, and pain assessment together; intervention words such as intubation, IV line, and defibrillation together; and documentation and communication words such as handover, clinical protocol, and nursing documentation together. Read nursing case studies and clinical guidelines in English to see the words in real contexts. Use the Flash Cards and Matching Pairs exercises on LexFizz to test your recall. Above all, practise using the terms aloud in simulated scenarios or with colleagues, because in an emergency department, confident verbal communication is just as important as written accuracy.
