EMT Exam Dumps - NREMT Medical Technicians Questions and Answers

Comprehensive and Detailed Explanation From Exact Extract:

According to Pediatric Basic Life Support (PBLS) guidelines by the American Heart Association (AHA), when a child becomes unresponsive due to foreign body airway obstruction (FBAO), the immediate next step is to begin chest compressions. This is done before checking the airway or giving breaths because the airway is presumed obstructed. The compressions may dislodge the object.

After 30 compressions, open the airway and check for visible objects. If none are seen, attempt rescue breaths. This protocol reflects the high risk of complete airway blockage in children with sudden collapse following a choking episode.

Children compensate for shock through increased heart rate, respiratory rate, and vasoconstriction, which delays blood pressure drop. Therefore:

Tachycardia is often the first sign

Prolonged capillary refill (>2 seconds) is an early indicator

Tachypnea supports perfusion

Blood pressure is a late sign in pediatric shock. SpO₂ is helpful but does not specifically indicate shock. Blood glucose may be abnormal in other metabolic conditions but is not an early marker of volume loss.

NREMT guidelines emphasize that patient refusal is only valid if the patient has decision-making capacity. This patient has a severe headache with critically elevated blood pressure, which raises concern for conditions such as hypertensive emergency, intracranial hemorrhage, or stroke—all of which can impair cognition.

Option D is correct because the EMT must first determine whether the patient is alert, oriented, understands the risks, and can communicate a rational decision. Without capacity, a refusal is not legally or ethically valid.

Option A is incorrect because a refusal form should only be signed after capacity is confirmed.

Option B does not address the legal and ethical priority.

Option C is unnecessary unless the patient lacks capacity and poses a danger to themselves or others.

NREMT stresses that EMTs must protect patient autonomy while ensuring informed refusal, especially in high-risk presentations.

Secondary prevention focuses on early detection and intervention to reduce the severity or impact of an illness or injury that has already occurred or is inevitable. Examples in EMS include:

AED deployment in public

Stroke recognition training

Early CPR

Primary prevention aims to stop the injury from occurring at all (e.g., vaccination, seatbelts). "Reactive" and "proactive" are not recognized formal categories in EMS public health strategy.

CPAP works by delivering continuous positive pressure to keep alveoli open and improve oxygenation. However, complications include:

Hypotension: Due to reduced venous return and cardiac preload

Feeling of suffocation: Common psychological reaction to a tight-fitting mask and forced airflow

It is used to treat, not cause, pulmonary edema. It does not induce bronchospasm or myocardial infarction.

Comprehensive and Detailed Explanation (Based on NREMT standards):

This patient has signs of penetrating chest trauma, severe hypotension, tachycardia, and respiratory distress. A gurgling chest wound suggests an open pneumothorax, which can progress to tension pneumothorax.

Option C (Obstructive shock) is correct because air trapped in the chest can compress the heart and great vessels, preventing adequate cardiac output.

Option A is less likely because although blood loss may be present, the chest injury suggests impaired circulation due to pressure.

Option B involves pump failure, not trauma-related compression.

Option D involves abnormal vessel dilation, not mechanical obstruction.

NREMT emphasizes rapid recognition of obstructive shock and immediate intervention with occlusive dressings and rapid transport.

Comprehensive and Detailed Explanation (Based on NREMT standards):

The patient’s signs—hip pain, deformity, and leg shortening—are consistent with a proximal femur or hip fracture. NREMT trauma care emphasizes immobilization, pain reduction, and prevention of further injury.

Option C (Apply mild traction) is appropriate to reduce muscle spasm and pain when a femur fracture is suspected and no contraindications are present.

Option D (Splint with blankets and pillows) is correct because soft splinting stabilizes the injury and limits movement during transport.

Option A is not required because oxygen saturation is adequate.

Option B is contraindicated because leg elevation may worsen pain or bleeding.

Option E is reserved for unstable pelvic fractures, not isolated hip fractures.

NREMT emphasizes gentle handling, immobilization, and rapid transport for suspected hip fractures.
