EMT Exam Dumps - Emergency Medical Technicians Exam

After ROSC in an unresponsive patient, the left lateral recumbent position (also called the recovery position) is preferred to:

Maintain an open airway

Prevent aspiration if vomiting occurs

Promote drainage of secretions

Supine or Trendelenburg positions increase the risk of aspiration. Elevating the head to 45° may reduce intracranial pressure, but it’s not standard post-ROSC care in an unresponsive patient unless airway protection is ensured.

In an unresponsive diabetic patient, EMTs must rapidly determine whether the cause is hypoglycemia (low blood glucose) or hyperglycemia (high blood glucose) because immediate management priorities differ. According to NREMT education, skin signs are the most reliable and quickly observable indicator when a blood glucose reading is not immediately available.

Hypoglycemia typically presents with cool, pale, and diaphoretic skin due to a sympathetic nervous system response. In contrast, hyperglycemia often presents with warm, dry skin, reflecting dehydration and lack of insulin-mediated glucose uptake.

Option D is correct because skin color and condition provide the most useful differentiation in the field.

Option A may help identify diabetic ketoacidosis (Kussmaul respirations) but is not the most consistent finding.

Option B is unreliable and nonspecific.

Option C may vary but does not clearly distinguish between the two conditions.

NREMT emphasizes treating unresponsive diabetics as hypoglycemic until proven otherwise, while using skin findings to guide clinical suspicion.

For suspected or confirmed tuberculosis (TB), the EMT should place a surgical mask on the patient, not a HEPA respirator. Surgical masks are used to contain droplets from the patient and reduce airborne transmission.

The EMT should wear a N95 or HEPA respirator to protect against inhaling airborne particles. Notification to the CDC is not the EMT’s responsibility — that falls to public health officials.

The correct answer is D. Apply CPAP.

This patient is experiencing respiratory distress following a drowning/submersion event, which strongly suggests aspiration and possible pulmonary edema. The key findings include:

Shallow respirations (R 28)

Persistent hypoxia (SpOâ‚‚ 92%) despite oxygen therapy

History of water exposure (lake rescue)

Why D is correct (CPAP):

CPAP provides positive pressure, helping to recruit alveoli and improve gas exchange.

It is especially effective in cases of noncardiogenic pulmonary edema, such as near-drowning.

Indicated when:

Patient is awake and breathing

Hypoxia persists despite oxygen therapy

Why the other options are incorrect:

A. 12-lead ECG → Not relevant to respiratory failure from drowning

B. Nitroglycerin → Used for cardiac chest pain/pulmonary edema of cardiac origin, not drowning

C. Rapid transport → Important, but does not address immediate respiratory failure; airway intervention takes priority

Exact Extracts:

“CPAP is indicated for patients with respiratory distress who do not improve with oxygen therapy.”

“Positive pressure ventilation helps improve oxygenation in patients with pulmonary edema.”

“Near-drowning patients may develop respiratory distress due to fluid in the lungs.”

The position of the patient’s head within the aircraft affects access to airway management and crew maneuverability. If the head is oriented away from providers or toward a non-accessible bulkhead, this can delay critical interventions (airway suctioning, ventilations).

Use of air splints, maintaining oxygen saturation, or environmental humidity are not major complications relative to physical positioning and in-cabin access limitations.

In cases of sexual assault, preserving evidence integrity is critical. Clothing or other forensic evidence must be placed in paper bags. Plastic or non-breathable materials can trap moisture, promoting mold or degradation of evidence like DNA or bodily fluids.

This approach follows chain-of-custody protocols used by law enforcement and medical facilities for handling forensic material.

The correct answers are A. Wear a safety vest, B. Limit scene time, and F. Park with wheels turned toward the scene.

Why A is correct (High-visibility vest):

EMS providers must wear ANSI-compliant reflective vests when operating on roadways

This significantly improves visibility, especially at night

NREMT-aligned guidance states:

“Wear high-visibility apparel when operating near traffic.”

Why B is correct (Limit scene time):

Reducing time on the roadway minimizes exposure risk

Rapid assessment, treatment, and transport are key safety strategies

“Minimize time spent in hazardous environments.”

Why F is correct (Wheel positioning):

Turning wheels toward the scene helps:

Prevent the ambulance from being pushed into responders if struck

Provide a protective barrier

“Position vehicles to protect the scene and personnel.”

Why the other options are incorrect:

C. Keep back turned to vehicles❌ Dangerous — EMTs should face traffic when possible

D. Place flares 10 feet away❌ Incorrect distance — flares should be placed much farther away for advance warning

E. Reduce scene lighting❌ Incorrect — proper lighting is essential for scene safety and visibility

Exact Extracts (NREMT-aligned EMT educational references):

“Use reflective safety vests when working on roadways.”

“Limit exposure time in hazardous scenes.”

“Position emergency vehicles to create a safe work zone.”

Clinical Priority Summary:

Key roadway safety measures include visibility, minimizing exposure, and proper vehicle positioning, making A, B, and F the correct answers.

The patient is in hypoperfusion (shock) from blood loss. In shock states, tissues are deprived of oxygen, leading to anaerobic metabolism, which produces lactic acid as a byproduct. This causes metabolic acidosis, which is a critical sign of systemic oxygen debt.

Carbon dioxide rises with respiratory failure, but lactic acid is a more specific indicator of cellular hypoxia.
