Sudden Medical Emergencies – Part 5: Poisoning and How to Help

🧠 Understanding the Risks of Poisoning in Nursing Practice

Poisoning emergencies can happen anywhere—homes, workplaces, long-term care facilities, or even within clinical environments. As a nursing student, understanding how toxins enter the body and how to safely intervene is critical. Poisons can be natural or synthetic, and even everyday substances like cleaning products or medications can be harmful if misused. Rapid recognition and response can save lives, but only when safety and proper procedures are followed.

🧬 The Four Routes of Exposure: Know the Entry Points

Recognizing how a poison enters the body is the first step toward effective treatment and prevention. These are the four primary exposure routes you must be familiar with:

Injected – Poisons that enter the body via bites, stings, needles, or intravenous drug use. Common in both natural (snake/insect) and clinical settings.
Inhaled – Gases, vapors, or fumes breathed into the lungs. These exposures are common in enclosed spaces or when chemical reactions release noxious gases.
Ingested – Swallowed toxins such as spoiled food, alcohol, cleaning chemicals, or medication overdoses.
Absorbed – Toxins absorbed through the skin from spills, contaminated surfaces, or direct exposure to corrosive substances.

Why It Matters: Each route produces different symptoms and requires different first aid protocols. Misidentifying the exposure could lead to inappropriate treatment and further harm.

🔍 Clinical Signs and Symptoms of Each Poisoning Route

Each form of poisoning presents with distinct signs. A nurse’s ability to assess the cause based on visible and reported symptoms helps guide emergency care:

Injected: Look for puncture wounds, redness, swelling, breathing difficulty, and altered level of consciousness (LOC). You may also notice nearby syringes, EpiPens, or recreational drug paraphernalia.
Inhaled: Symptoms include coughing, throat irritation, dizziness, bluish lips, disorientation, or seizures. Be cautious of unusual odors, foggy air, or respiratory distress.
Ingested: Watch for burns around the mouth, excessive or oddly colored saliva, nausea, vomiting, diarrhea, or unconsciousness.
Absorbed: Skin reactions like redness, itching, swelling, hives, or blistering. Prolonged exposure can lead to systemic symptoms or shock.

Why It Matters: Knowing the clinical presentation enables you to make rapid decisions, document symptoms accurately, and prepare for appropriate interventions while awaiting EMS.

🛡️ Prevention: A Key Nursing Responsibility

As a nursing professional, prevention is part of patient safety. Whether educating families or preparing a workplace, here are best practices you should know:

Store all medications and chemicals in original containers with proper labeling.
Use child-resistant packaging and keep toxins out of children’s reach.
Educate clients and families never to refer to medicine as “candy.”
Dispose of expired medications through pharmacies—never in the trash or toilet.
Always read labels three times: when removing, preparing, and administering.
Avoid mixing cleaning agents (e.g., bleach + ammonia = fatal gas).
Wear personal protective equipment (PPE) when handling unknown substances.
Ensure areas are well-ventilated before using household or healthcare chemicals.

Why It Matters: Nurses serve as frontline educators for poison prevention. Reinforcing these practices with clients, families, and care teams significantly reduces accidental exposure.

🧾 WHMIS / GHS: Understanding Workplace Chemical Safety

In Canada, WHMIS 2015 (aligned with GHS, the Global Harmonization System) governs how chemicals are labeled and handled in clinical and industrial settings. Nursing students must be familiar with:

SDS (Safety Data Sheets): These outline every chemical’s hazards, PPE requirements, first aid instructions, and disposal methods.
Hazard Symbols: Easily identify flammables, corrosives, biohazards, and more.
Labeling and Storage Protocols: Replace missing or damaged labels immediately.
Certification: WHMIS certification is mandatory for most healthcare roles and often available online.

Why It Matters: Understanding WHMIS protects you, your patients, and your coworkers from chemical harm and ensures you're meeting legal and ethical obligations in the workplace.

🚨 Emergency First Aid for Poisoning Victims

Step 1: Ensure Scene Safety

Before you approach, check for hazards. Wear gloves, a mask, or full PPE depending on the environment. If airborne chemicals are suspected, do not enter—call EMS. Your safety always comes first.

Step 2: Activate EMS and Poison Control

Call 911. If poison control is not immediately available, EMS will connect you. Provide the substance name (from packaging or SDS) and the exposure route.

Step 3: Care According to Exposure Type

Inhaled: Move the person to fresh air if safe. Never enter a toxic environment.
Ingested: Never induce vomiting unless advised. Save packaging for EMS.
Absorbed: Remove contaminated clothing. Rinse skin under cool water for 15–20 minutes.
Injected: Keep the limb below heart level. Do not cut or suck the wound. Monitor ABCs.

Why It Matters: Each exposure type demands unique care. As a nursing student, following these steps demonstrates both clinical competence and adherence to legal safety protocols.

🤲 Recovery Position: Protecting the Unconscious but Breathing Patient

If the poisoned person is unresponsive but still breathing, place them in the recovery position:

Raise the far arm above the head.
Place the near arm across the chest.
Bend the near leg at the knee.
Support the head and neck while gently rolling them onto their side.
Tilt the head to maintain airway patency.
Stabilize with the bent knee and elbow.
Monitor breathing continuously.

Why It Matters: Proper positioning reduces the risk of airway obstruction and aspiration while awaiting medical help—crucial when vomiting or unconsciousness is involved.

📌 Final Thoughts for Nursing Students

Poisonings are high-stakes events that require calm, confident, and evidence-informed intervention. As a nursing student, you must be aware of toxic substances both in the hospital and at home, understand how to respond without becoming a victim yourself, and support recovery until EMS arrives.

Whether you're reviewing WHMIS protocols, guiding a family on medication safety, or managing an emergency, your knowledge will make a lasting difference in someone’s life.
