EMR First Responder Principles 2 — Questions and Answers
Question 1: What does the term 'Standard Precautions' mean in the context of EMS?
- Treating only patients who consent to care
- Assuming all patients may carry infectious pathogens and using appropriate PPE for every patient encounter (Correct answer)
- Wearing gloves only when blood is visibly present
- Using sterile technique for all wound dressings
Correct answer: Assuming all patients may carry infectious pathogens and using appropriate PPE for every patient encounter
Standard Precautions are infection control measures that assume all patients — regardless of diagnosis — may carry bloodborne or airborne pathogens. They require gloves for every patient contact, and additional PPE (mask, eye protection, gown) when exposure to body fluids is anticipated.
Standard Precautions (formerly Universal Precautions) were established to protect healthcare workers from exposure to bloodborne pathogens (HIV, hepatitis B, hepatitis C) and other infectious agents. Because patients may carry pathogens without symptoms or known diagnosis, EMS providers treat every patient encounter as a potential exposure risk. Minimum PPE includes gloves for every patient contact. When aerosol-generating procedures (BVM ventilation, suctioning) are performed, a mask and eye protection are also required. A gown should be worn when large-volume blood or body fluid contamination is anticipated. This approach protects both EMS personnel and patients from cross-contamination.
Question 2: An EMR is dispatched to a scene involving a chemical spill with multiple casualties. What is the FIRST priority upon arrival?
- Begin triage and treatment of the most critically injured patient
- Establish scene safety, ensure no one enters the hot zone without appropriate hazmat PPE (Correct answer)
- Request additional ambulances from dispatch
- Attempt to identify the chemical by reading container labels
Correct answer: Establish scene safety, ensure no one enters the hot zone without appropriate hazmat PPE
Scene safety is always the first priority. At a hazmat scene, no EMS provider should enter the hot zone without proper hazmat PPE. Entering without protection risks the provider becoming a victim, creating additional casualties.
The fundamental principle of EMS response to hazardous materials scenes is: do not enter the hot (exclusion) zone without appropriate chemical protective equipment. Doing so places the EMR at risk of chemical exposure and turns them into an additional casualty rather than a rescuer. Upon arrival, the EMR should: 1) approach from upwind/uphill, 2) establish scene safety from the cold (support) zone, 3) identify the hazmat through placards, shipping manifests, or CHEMTREC, 4) request specialized hazmat teams, and 5) establish triage in the cold zone for decontaminated patients. Treatment and triage begin only after decontamination.
Question 3: Which of the following is an example of expressed consent?
- An unconscious patient who cannot respond but would likely want care
- A patient who verbally or physically agrees to receive treatment (Correct answer)
- A minor receiving emergency care without parental consent present
- Providing care to a patient who was confused but did not refuse
Correct answer: A patient who verbally or physically agrees to receive treatment
Expressed consent is when a patient verbally or physically (e.g., nodding, extending arm for treatment) consents to receive care. It requires the patient to be informed of the treatment and competent to consent.
There are three main types of consent in EMS: Expressed (explicit) consent — the patient actively agrees to treatment after being informed of what will be done, the risks, and alternatives; Implied consent — assumed for unconscious, severely altered, or incapacitated adults in emergencies (the 'reasonable person' standard); and Minor consent — parents or guardians provide consent for children, except in life-threatening emergencies where implied consent applies. Expressed consent is the gold standard and requires the patient to be of legal age, conscious, oriented, and not under the influence of substances that impair judgment.
Question 4: A patient with chest pain and diaphoresis asks the EMR what is wrong with him. The EMR suspects a myocardial infarction but is not certain. What is the most appropriate response?
- Tell the patient he is definitely having a heart attack
- Explain the symptoms that are concerning and that he needs further evaluation at the hospital (Correct answer)
- Withhold all information to prevent patient panic
- Reassure him that everything is fine and there is nothing to worry about
Correct answer: Explain the symptoms that are concerning and that he needs further evaluation at the hospital
EMRs should communicate honestly without exceeding their scope of practice. Telling a patient what is concerning (symptoms suggesting possible cardiac origin) and that further evaluation is needed is truthful, professional, and does not involve making a definitive diagnosis beyond the EMR's scope.
Effective EMR communication balances honesty with professional boundaries. EMRs do not make medical diagnoses — that is the role of physicians. However, withholding all information is unethical and unhelpful. The appropriate response is to inform the patient of the signs and symptoms that are concerning (chest pain with sweating can be serious), explain that further evaluation at the hospital is necessary, and reassure the patient that appropriate care is being provided. This respects patient autonomy (informed consent), maintains professional credibility, and keeps the patient cooperative during treatment and transport.
Question 5: Which document establishes a patient's right to refuse resuscitation in the out-of-hospital setting?
- A living will alone is sufficient to stop CPR
- A Do Not Resuscitate (DNR) order or POLST form signed by a physician (Correct answer)
- A family member's verbal statement that the patient did not want CPR
- Any written note from the patient indicating their wishes
Correct answer: A Do Not Resuscitate (DNR) order or POLST form signed by a physician
A valid DNR order or Physician Orders for Life-Sustaining Treatment (POLST) signed by a licensed physician is the legally recognized document that allows EMS providers to withhold resuscitation in the field.
To legally honor a patient's wish not to be resuscitated, EMS providers typically require a physician-signed DNR order or POLST (Physician Orders for Life-Sustaining Treatment). Requirements vary by state, but in general: the document must be signed by a physician, be for the specific patient present, and be available at the scene. A living will is a legal document expressing preferences but may not be immediately recognized in the field without a physician co-signature on a POLST or DNR. Verbal statements from family members, even if sincere, do not legally authorize withholding CPR. When in doubt, EMRs should begin resuscitation and contact medical direction.
Question 6: What is the MOST appropriate action when an EMR suspects elder abuse during a patient assessment?
- Confront the suspected abuser at the scene
- Document observations objectively and report to appropriate authorities per protocol (Correct answer)
- Do not document suspicions to avoid false accusations
- Ask the patient directly if they are being abused in front of the family
Correct answer: Document observations objectively and report to appropriate authorities per protocol
EMRs are mandatory reporters of suspected abuse. The correct action is to document findings objectively (bruising inconsistent with explanation, signs of neglect, fear in the patient) and report to receiving hospital staff and authorities per local protocol.
In most jurisdictions, EMTs and first responders are designated mandatory reporters, legally required to report suspected abuse, neglect, or exploitation of vulnerable populations (children, elders, persons with disabilities). When elder abuse is suspected, the EMR should: 1) ensure the patient's immediate safety, 2) document objective findings (unexplained injuries, poor hygiene, multiple old injuries in various stages of healing, fear or flinching from caregiver), 3) avoid confronting the suspected abuser on scene (this may escalate danger), 4) report findings to the receiving emergency department and to Adult Protective Services per local protocol. Do not ask the patient about abuse in front of the suspected abuser.
