Pass the NREMT Medical Technicians EMT Questions and answers with Dumpstech

Organophosphates are commonly found in pesticides and insecticides, which are often stored in tool sheds. NREMT training emphasizes recognition of cholinergic toxidrome, frequently summarized by the mnemonic SLUDGE (Salivation, Lacrimation, Urination, Defecation, Gastrointestinal distress, Emesis).

Option C is correct because the patient’s symptoms—drooling, tearing, abdominal pain, and runny nose—are hallmark signs of organophosphate poisoning.

Option A (naphthalene) primarily causes hemolysis and neurologic symptoms.

Option B (hydrogen sulfide) causes respiratory distress and altered mental status, not secretions.

Option D causes chemical pneumonitis, not cholinergic symptoms.

NREMT stresses early identification of toxic exposures, scene safety, decontamination awareness, and rapid transport for definitive care.

Comprehensive and Detailed Explanation (Based on NREMT standards):

For a conscious adult with complete airway obstruction, abdominal thrusts are typically indicated. However, NREMT guidelines specify that chest thrusts should be used instead for patients who are morbidly obese or pregnant, because abdominal thrusts may be ineffective or unsafe.

Option D is correct because chest thrusts provide effective airway clearance while accommodating body habitus.

Options A and B are inappropriate for a conscious patient.

Option C is incorrect because abdominal thrusts may not be effective in morbidly obese patients.

NREMT stresses modifying airway obstruction techniques based on patient size and condition.

Comprehensive and Detailed Explanation From Exact Extract:

The patient’s symptoms are consistent with acute coronary syndrome (ACS). The first-line treatments are:

Aspirin (160–325 mg): inhibits platelet aggregation, reducing clot progression.

Oxygen: administered when SpO₂ <94% or signs of hypoxia/distress are present.

CPAP is for pulmonary edema or respiratory failure. Nitroglycerin requires BP >90 systolic and medical direction approval. Laying the patient supine may increase myocardial workload and is inappropriate unless hypotension occurs.

The cerebrum is the largest and most developed part of the human brain and is responsible for higher cognitive functions. According to NREMT anatomy and physiology education, the cerebrum controls thinking, reasoning, memory, judgment, voluntary movement, and sensory interpretation.

Option B is correct because conscious thought, problem-solving, and decision-making all originate in the cerebrum.

Option A (Pons) helps regulate breathing and sleep cycles.

Option C (Brain stem) controls vital functions such as heart rate, breathing, and blood pressure.

Option D (Cerebellum) coordinates balance, posture, and fine motor movement.

Understanding brain function helps EMTs correlate neurological findings with possible injuries or medical conditions.

Comprehensive and Detailed Explanation (Based on NREMT standards):

Hepatitis A is a viral liver infection transmitted primarily through the fecal-oral route, often due to contaminated food, water, or poor hand hygiene. NREMT education highlights hepatitis transmission routes as part of infection control and standard precautions.

Option A is correct because hepatitis A spreads when microscopic amounts of fecal matter are ingested, commonly in environments with inadequate sanitation.

Options B, C, and D are incorrect because these forms of hepatitis are transmitted primarily through blood and body fluids, such as needlestick injuries, sexual contact, or shared needles.

Understanding transmission routes allows EMTs to apply proper protective measures and reduce occupational exposure risks, a core component of NREMT infection-control training.

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.

Using the START triage system, patients are categorized based on Respirations, Perfusion, and Mental Status (RPM).

A respiratory rate greater than 30 breaths per minute immediately qualifies the patient as RED (Immediate). Additionally, delayed capillary refill (>2 seconds) further supports this classification.

Option A is correct.

Option B applies to stable patients who can wait.

Option C is for deceased or nonsalvageable patients.

Option D is for minor injuries.

NREMT teaches that patients with compromised airway or perfusion are the highest priority.

According to NREMT neonatal resuscitation principles, a newborn who is crying with a heart rate greater than 100 does not require aggressive resuscitation but does need supportive care.

Option A (Dry baby) is essential to stimulate breathing and prevent heat loss.

Option B (Keep baby warm) is critical, as neonates lose heat rapidly and hypothermia worsens hypoxia.

Option C (Administer blow-by oxygen) is appropriate for central cyanosis when respirations and heart rate are adequate.

Option D is only indicated if secretions are obstructing the airway.

Options E and F are contraindicated because the infant has an adequate heart rate and is breathing.

NREMT emphasizes warmth, oxygenation, and minimal intervention in stable newborns.

Comprehensive and Detailed Explanation From Exact Extract:

In pediatric START or JumpSTART triage, a "delayed" status is appropriate if the child is breathing adequately, has palpable pulses, and follows commands. The respiratory rate of 16 is normal for a 9-year-old, and being able to walk also supports the “delayed” tag.

"Mottled skin" and "breathing only after airway opening" would more likely lead to "immediate" or even "expectant" categories depending on associated symptoms.

When an incident involves multiple agencies with shared responsibility, NREMT teaches that a Unified Command structure is used. This allows police, fire, EMS, and other agencies to work together under a common set of objectives while maintaining their individual authority.

Option C is correct because the defining feature of unified command is multi-agency involvement, not rank or arrival order.

Option A is incorrect because no single agency automatically has authority.

Option B misunderstands unified command, which still functions with coordinated leadership.

Option D is incorrect because EMS does not automatically become part of command.

NREMT emphasizes unified command to improve coordination, communication, and safety during MCIs.
