Ace Your EMT Medical Technicians Exam

Comprehensive and Detailed Explanation From Exact Extract:

In Incident Command System (ICS) for Mass Casualty Incidents (MCI), the four major sections are:

Planning: Collects data and develops response strategies

Logistics: Supplies and personnel

Finance/Administration: Cost tracking, contracts, compensation

Staging is a tactical location, not a management section. Catering and aviation are not command-level ICS designations unless part of specific tasks under logistics or operations.

Return of spontaneous circulation (ROSC) indicates that the patient has regained a perfusing rhythm. If the patient is pushing away the BVM, this suggests improving mental status and spontaneous respirations.

Option D is correct because NREMT post-resuscitation care requires EMTs to reassess airway, breathing, and circulation, including confirming a pulse, and transition from assisted ventilations to supplemental oxygen if the patient is breathing adequately.

Options A and B are inappropriate because restraining a post-ROSC patient is rarely indicated and may worsen agitation.

Option C omits reassessment of circulation, which is critical after ROSC.

NREMT stresses frequent reassessment and supportive care following successful resuscitation.

Comprehensive and Detailed Explanation From Exact Extract:

In patients with asthma experiencing respiratory failure, improper ventilation (especially excessive rates) can lead to air trapping and increased intrathoracic pressure, reducing venous return and worsening hypotension. The correct technique is to ventilate slowly to allow full exhalation — around 1 breath every 5–6 seconds for adults.

CPAP is contraindicated in unresponsive patients who cannot maintain their own airway. A non-rebreather mask would be insufficient for an unresponsive patient, and forceful ventilation risks barotrauma.

Comprehensive and Detailed Explanation From Exact Extract:

Heat exhaustion results from prolonged exposure to elevated temperatures, leading to fluid and electrolyte loss (especially sodium and water), causing hypovolemia. This can result in:

Tachycardia

Weakness

Dizziness

Profuse sweating

Unlike heat stroke, mental status is typically preserved in heat exhaustion. Hypertension and bradycardia are not characteristic.
