Pass the NREMT Medical Technicians EMT Questions and answers with ExamsMirror

Comprehensive and Detailed Explanation From Exact Extract:

Mental statusreflects perfusion and oxygen delivery to thebrain, which is highly sensitive to hypoxia and hypercapnia. Even if respiratory rate and SpO₂ are normal, altered mental status suggests ineffective gas exchange or hypoperfusion.

Pulse oximetry may be falsely normal in CO poisoning or poor perfusion. Skin color is subjective and not as sensitive or specific as neurological status.

In pediatric START orJumpSTARTtriage, 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.

These symptoms are classic forendometriosis, whereendometrial tissue grows outside the uterus. Symptoms often include:

Pelvic pain

Painful menstruation (dysmenorrhea)

Painful bowel movements or intercourse

Spontaneous abortion does not apply here due to lack of pregnancy. Premature menopause is rare at this age and presents differently. Infection is less likely in the absence of recent sexual activity or fever.

InIncident Command System (ICS)for Mass Casualty Incidents (MCI), the four major sections are:

Planning: Collects data and develops response strategies

Logistics: Supplies and personnel

Finance/Administration: Cost tracking, contracts, compensation

Stagingis atactical location, not a management section.Catering and aviationare not command-level ICS designations unless part of specific tasks under logistics or operations.

Thefirst step in hemorrhage controlfor external bleeding is alwaysdirect pressureusing gloved hands or dressing. Only if this fails or the bleeding issevere and life-threatening(especially from extremities) should atourniquetbe applied.

Assessing the airway is critical in overall trauma care but not thefirst priorityin isolated extremity hemorrhage. Severity assessment is secondary tobleeding control.

This is ahigh-risk cardiac eventdue to unstable angina or possiblemyocardial infarction. The EMT should:

Administer oxygenif SpO₂ is <94%

Avoid nitroglycerinif systolic BP is <90 mmHg

Obtain a 12-lead ECGto identify ST-elevation MI (STEMI) and transmit it if trained and authorized

CPAP is indicated forpulmonary edema, and albuterol is forbronchospasm, neither of which applies here.

Comprehensive and Detailed Explanation From Exact Extract:

Hepatitis Avirus is transmittedexclusively via the fecal-oral route. Ingesting contaminated food or water allows the virus to enter the digestive tract, infecting liver cells. It's often spread through poor hand hygiene or unsanitary food handling.

It isnot bloodborne, unlike Hepatitis B and C. It is not commonly spread through saliva or urine.

Comprehensive and Detailed Explanation From Exact Extract:

Thepatient’s complaint of difficulty breathingis anairway/breathing issueand takes precedence over a controlled extremity bleed. The first action is toadminister oxygenand evaluate respiratory effort.

Though reassessing the wound is important,oxygenation is the prioritywhen airway compromise or respiratory distress is present. Tourniquets are foruncontrolled bleeding, which is not the case here.

Comprehensive and Detailed Explanation From Exact Extract:

In cases ofsexual assault, preservingevidence integrityis critical. Clothing or other forensic evidence must be placed inpaper bags. Plastic or non-breathable materials can trap moisture, promotingmold or degradation of evidencelike DNA or bodily fluids.

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

Comprehensive and Detailed Explanation From Exact Extract:

The patient's symptoms are consistent with astroke (CVA). Proper prehospital care focuses on maintaining airway, breathing, circulation, and protecting the affected limbs.Positioning the patient with head elevated(not supine) reduces intracranial pressure and aspiration risk.

Protecting theparalyzed side (e.g., left arm)from injury during transport is critical. EMS should still communicate with the patient — even if speech is impaired — and perform a stroke assessment using tools likeCincinnati Prehospital Stroke Scale (CPSS)orFAST.
