The single most important skill in emergency response is not knowing CPR or first aid — it's recognizing that an emergency is happening in the first place. Delayed recognition is the most common reason home care emergencies become fatalities. This lesson builds your ability to detect emergencies early, act without hesitation, and stay effective under pressure.

Section 01

The Core Decision: 911 or Nurse?

Every emergency situation requires a fast, correct first decision: call 911 or call the supervising nurse. Getting this wrong wastes critical time. The rule is simple:

🚨 Call 911 First

  • Unconscious or unresponsive
  • Not breathing or abnormal breathing
  • Chest pain or pressure
  • Signs of stroke (FAST)
  • Severe allergic reaction
  • Uncontrolled bleeding
  • Seizure for first time or lasting 5+ min
  • Suspected overdose
  • Severe fall with head injury
  • Sudden severe confusion

⚠ Call Nurse — Same Day

  • Fever over 101°F
  • Significant new pain
  • Moderate confusion — new onset
  • Wound that looks infected
  • Client hasn't eaten or drunk all day
  • Medication error or missed dose
  • Significant behavior change
  • Vital signs outside normal range
  • Client requests to go to hospital
  • Any situation you're unsure about
💡 When in doubt — call 911
It is always better to call 911 for something that turns out not to be an emergency than to delay calling for something that is. Emergency services would rather respond to a false alarm than arrive too late. Err toward action.
Section 02

Stroke: FAST Recognition

Stroke is a leading cause of death and disability in older adults. Every minute without treatment, approximately 1.9 million brain cells die. Early recognition is the difference between recovery and permanent disability.

🚨 FAST — Stroke Warning Signs
  • F — Face drooping: Ask the client to smile. Is one side of their face drooping or numb?
  • A — Arm weakness: Ask them to raise both arms. Does one drift downward?
  • S — Speech difficulty: Ask them to repeat a simple sentence. Is their speech slurred, strange, or absent?
  • T — Time to call 911: If ANY of these are present — call 911 immediately. Note the exact time symptoms started.
Stroke treatment (clot-busting medication) must be given within 3–4.5 hours of symptom onset. The time you note is critical clinical information for the ER team.
⚠ Additional stroke warning signs
Sudden severe headache with no known cause, sudden vision problems in one or both eyes, sudden loss of balance or coordination, sudden numbness or weakness on one side of the body — even without the classic FAST signs.
Section 03

Heart Attack Recognition

Heart attacks in older adults — especially women — often present differently than the classic "crushing chest pain" portrayed in media. Knowing the full range of symptoms prevents missed diagnoses.

  • Chest discomfort: Pressure, squeezing, fullness, or pain in the center of the chest lasting more than a few minutes, or coming and going.
  • Radiating pain: Discomfort spreading to shoulders, neck, jaw, back, or arms — particularly the left arm.
  • Shortness of breath: With or without chest discomfort.
  • Other signs: Cold sweat, nausea, lightheadedness — common in women and older adults even without chest pain.
  • Atypical presentations: Indigestion-like symptoms, jaw pain, or unusual fatigue — especially in women and diabetic clients whose nerve sensitivity is reduced.
🚨 Call 911 — do not drive to the hospital
Never drive a client with suspected heart attack symptoms to the hospital. Call 911 — paramedics can begin treatment en route and alert the hospital, which reduces time to treatment significantly. Have the client sit or lie in a comfortable position. If prescribed and not allergic, aspirin (325mg) may be given if instructed by the 911 dispatcher.
Section 04

Respiratory Emergencies

Breathing problems can escalate rapidly in older adults with COPD, heart failure, or asthma. Knowing the difference between manageable difficulty and an emergency is critical.

🫁

Signs requiring 911

Unable to speak in full sentences due to breathlessness. Lips or fingertips turning blue (cyanosis). Breathing rate very fast (over 30 per minute) or very slow. Gurgling or rattling sounds. Using neck and shoulder muscles to breathe. Client says they feel like they're dying.

📞

Signs requiring same-day nurse call

New shortness of breath with exertion that wasn't present before. Mild wheeze that doesn't respond to inhaler. Persistent cough with colored mucus. Breathing that seems harder than usual but client is speaking normally.

💊

Rescue inhalers

Clients with COPD or asthma may have a rescue inhaler (blue inhaler — usually albuterol/salbutamol). Know where it is. If the client uses it and symptoms don't improve within 15–20 minutes, call 911. If they use it more than twice in one day, call the supervising nurse.

Section 05

Altered Mental Status: When Confusion Is an Emergency

New or sudden confusion in an older adult is a medical emergency until proven otherwise. It can signal stroke, infection, medication toxicity, low blood sugar, or other life-threatening conditions.

  • Sudden onset: The client was fine an hour ago and is now confused, disoriented, or agitated — this is an emergency. Call 911.
  • Baseline matters: A client with dementia who is always somewhat confused is different from a sharp client who is suddenly not recognizing their surroundings. Know your client's baseline and respond to deviation from it.
  • Delirium vs. dementia: Delirium (sudden, fluctuating confusion) is a medical emergency. Dementia progresses slowly. New sudden confusion in any client — including those with dementia — requires immediate clinical evaluation.
  • Don't try to reason through it: Do not spend time trying to reorient a suddenly confused client. Assess for stroke (FAST), check for injury, call for help.
Section 06

Staying Calm and Effective Under Pressure

Your ability to act effectively in an emergency depends on preparation — not just training, but mental readiness. These practices build the calm, decisive response emergencies require.

✓ Emergency preparedness habits
  • Know the client's full address — including apartment number and gate codes — before every shift starts
  • Know where the client's medication list is kept — have it ready for EMS
  • Know the client's emergency contacts and have them accessible
  • Know if the client has a DNR (Do Not Resuscitate) order — and where it is posted
  • Have 911 and Poison Control (1-800-222-1222) mentally ready — don't search for them in a crisis
  • Know the location of the nearest AED if in a building with one
