Newly Released NREMT EMT Exam PDF

Comprehensive and Detailed Explanation From Exact Extract:

Perfusion refers to delivery of oxygen and nutrients to tissues. It depends on three essential components:

Patent airway: Ensures oxygen reaches lungs

Intact microcirculation: Capillary-level exchange must function

Sufficient blood volume: Maintains blood pressure and oxygen transport

Hypoxic drive relates to COPD physiology, not perfusion. High alveolar pressure (like from CPAP) may impede venous return, and a low ventilation-perfusion ratio means poor oxygenation efficiency, which negatively affects perfusion.

Pursed-lip breathing is a classic compensatory mechanism seen in patients with emphysema, a form of chronic obstructive pulmonary disease (COPD). According to NREMT education, emphysema is characterized by destruction of the alveolar walls, which leads to loss of lung elasticity. This loss prevents the small airways from remaining open during exhalation.

Option A is correct because pursed-lip breathing creates positive pressure in the airways during exhalation. This pressure helps keep collapsed airways open longer, allowing trapped air to escape and improving ventilation. It also reduces the work of breathing and helps alleviate dyspnea.

Option B is incorrect because decreased hemoglobin affects oxygen-carrying capacity, not airway mechanics or breathing patterns.

Option C is more commonly associated with chronic bronchitis, not emphysema.

Option D is incorrect because diaphragmatic dysfunction is not the primary cause of pursed-lip breathing.

NREMT emphasizes recognizing compensatory breathing patterns in chronic lung disease to guide supportive care, including oxygen administration and positioning.

A deposition is a formal legal proceeding in which sworn testimony is taken prior to trial. NREMT education on EMS operations, documentation, and legal responsibilities emphasizes that EMTs may be required to participate in depositions as part of civil or criminal cases involving patient care.

Option C is correct because attorneys for all involved parties are typically present during a deposition. These may include attorneys representing the plaintiff, defendant, EMS agency, or insurance providers. The EMT provides sworn testimony under oath, and the deposition may later be used in court.

Option A is incorrect because deposition testimony is admissible in court under many circumstances.

Option B is incorrect because depositions are not presided over by a judge; they are conducted by attorneys.

Option D is incorrect because exhibits such as patient care reports, protocols, or photographs may be introduced during a deposition.

NREMT stresses the importance of accurate documentation, professionalism, and honesty, as EMTs are legally accountable for their actions and statements.

NREMT guidelines specify that adult ventilations with a BVM should be delivered over approximately 1 second, just enough to see visible chest rise. Forceful, rapid ventilations increase the risk of gastric inflation, aspiration, barotrauma, and hypotension.

Option B is correct because slowing the rate and reducing force improves ventilation effectiveness and patient safety.

Option A may be important, but the primary error described is ventilation speed.

Option C is inappropriate for an apneic patient.

Option D is only indicated if the patient is pulseless.

NREMT emphasizes controlled, gentle ventilations to minimize complications.
