NREMT Medical Technicians EMT New Questions

Comprehensive and Detailed Explanation From Exact Extract:

The tripod position — sitting upright, leaning forward, supporting the upper body with arms on knees — is a classic sign of respiratory distress. This position:

Maximizes diaphragmatic movement

Engages accessory muscles of respiration

Improves air exchange in patients with obstructive airway diseases (e.g., COPD, asthma)

It is rarely used by patients with abdominal pain or seizures and is not associated with cardiac arrest (where unconsciousness is expected).

The diaphragm is innervated by the phrenic nerve, which originates from spinal nerve roots C3–C5. NREMT teaching highlights the phrase: “C3, 4, and 5 keep the diaphragm alive.”

Option A (C4) is correct because an injury at or above this level can paralyze the diaphragm, resulting in apnea and immediate respiratory failure.

Option B (T1) and C (T3) affect intercostal muscles but not the diaphragm.

Option D (L4) affects lower extremity function only.

NREMT emphasizes that high cervical spine injuries are immediately life-threatening due to loss of ventilatory control.

Comprehensive and Detailed Explanation From Exact Extract:

Contraindications to CPAP (Continuous Positive Airway Pressure) include:

Hypotension: CPAP can reduce preload and worsen shock (BP < 90 systolic is a contraindication)

Respiratory rate too low: A rate of 10 is at the low threshold; CPAP requires spontaneous adequate effort

Active vomiting or nausea: CPAP increases aspiration risk

Crackles and hypoxia are indications, not contraindications, for CPAP. Pulse rate does not influence CPAP use directly.

NREMT legal education differentiates between slander and libel, both forms of defamation.

Option D (Libel) is correct because libel involves false written statements that harm a person’s reputation. In this scenario, the partner’s written claim falsely attributes improper treatment to you.

Option A (Slander) refers to spoken false statements.

Option B (Malice) describes intent, not a legal category of defamation.

Option C (Battery) is unlawful physical contact with a patient.

Understanding legal terminology helps EMTs protect themselves professionally and legally.
