NEW QUESTION # 155
Witnesses state a patient is unresponsive and not breathing after a vehicle collision. What action should the EMT perform first?
Answer: B
NEW QUESTION # 156
A 44-year-old patient is unresponsive, and an EMT checks for a pulse prior to applying an AED. Which of the following shockable rhythms, ventricular fibrillation or ventricular tachycardia, if either, may still produce a pulse in this patient?
Answer: B
Explanation:
The correct answer is B. Ventricular tachycardia only.
There are two primary shockable rhythms in cardiac arrest:
Ventricular fibrillation (VF)
Ventricular tachycardia (VT)
However, only one of these may still produce a pulse under certain conditions.
Why B is correct:
Ventricular tachycardia (VT) can occur with or without a pulse.
In some cases, VT allows the heart to generate enough cardiac output to produce a palpable pulse (this is called stable or unstable VT with a pulse).
Therefore, VT is the only shockable rhythm that may still have a pulse.
Why the other options are incorrect:
A). Ventricular fibrillation only # VF produces no organized cardiac activity, therefore no pulse C). Both shockable rhythms # Incorrect because VF never produces a pulse D). Neither a shockable rhythm # Incorrect because VT can produce a pulse Exact Extracts:
"Ventricular fibrillation results in no effective cardiac output and no pulse."
"Ventricular tachycardia may be present with or without a pulse."
"Pulseless ventricular tachycardia and ventricular fibrillation are treated with defibrillation." References:

NEW QUESTION # 157
An EMT has been assigned as the treatment supervisor at a mass casualty incident. Which of the following actions should the EMT perform?
Answer: B
Explanation:
The correct answer is D. Ensure that secondary triage is completed.
Role of Treatment Supervisor in MCI (Mass Casualty Incident):
In the Incident Command System (ICS), responsibilities are divided:
* Triage Supervisor # performs initial triage
* Treatment Supervisor # manages patient care after triage
* Transport Supervisor # coordinates transport to hospitals
* Staging Officer # manages personnel/equipment staging
Primary responsibility of Treatment Supervisor:
* Oversee treatment areas (Immediate, Delayed, Minor)
* Ensure patients are reassessed and re-triaged (secondary triage)
* Monitor patient conditions and prioritize care
NREMT-aligned guidance states:
* "The treatment supervisor is responsible for patient care and reassessment."
* "Secondary triage is performed in the treatment area."
Why D is correct:
* Secondary triage ensures patients are:
* Reevaluated
* Properly prioritized as conditions change
* This is a core responsibility of the treatment supervisor
Why the other options are incorrect:
* A. Command triage personnel# Responsibility of the Triage Supervisor
* B. Establish staging area# Responsibility of the Staging Officer
* C. Coordinate transportation# Responsibility of the Transport Supervisor Exact Extracts (NREMT-aligned EMT educational references):
* "Treatment unit is responsible for treatment and secondary triage."
* "Transport officer coordinates patient movement to hospitals."
* "Staging manages resources and personnel."
Clinical Priority Summary:
The treatment supervisor's primary role is to manage patient care and ensure ongoing reassessment, including secondary triage, making D the correct answer.

NEW QUESTION # 158
A patient is having an asthmatic attack. The EMT receives orders from medical control to assist with the patient ' s inhaler. What are the expected side effects of this medication? Select the three correct options.
Answer: C,D,F
Explanation:
Albuterol, a common beta-2 adrenergic agonist used in inhalers, stimulates bronchial smooth muscle relaxation. However, stimulation of beta receptors can also produce systemic effects such as:
* Tachycardia (due to beta-1 cross-reactivity)
* Nervousness (from central stimulation)
* Coughing (a local airway response)
Confusion and drowsiness are not typical side effects of beta-agonists. Hypotension is rare unless severe overdose occurs.

NEW QUESTION # 159
In which of the following positions should a patient with an altered level of consciousness be transported?
Answer: C
Explanation:
Comprehensive and Detailed Explanation (Based on NREMT standards):
Patients with an altered level of consciousness are at increased risk of airway compromise due to loss of protective reflexes. NREMT guidelines stress the importance of airway protection during transport.
The left lateral recumbent position (recovery position) is preferred because it allows secretions, vomitus, or blood to drain from the mouth, reducing the risk of aspiration. This position also helps maintain airway patency without requiring invasive airway devices.
Option A may be appropriate for respiratory distress but does not adequately protect the airway in patients with decreased consciousness.
Option C is unsafe because the patient cannot maintain posture or airway control.
Option D increases aspiration risk unless spinal precautions are required.
NREMT teaches that airway protection is the priority when transporting patients with altered mental status.
