Free Practice Questions for NREMT EMT Exam

Clavicle deformity suggests potential rib or thoracic trauma. Unequal chest rise may indicate a flail segment, pneumothorax, or hemothorax. Subcutaneous emphysema, the presence of air under the skin, is a classic finding in pneumothorax or tracheobronchial injury.

Occipital depression is not chest related; epigastric distension is a GI symptom; and jugular vein distention would suggest tension pneumothorax or cardiac tamponade, which are more advanced complications.

The correct answer is D. Use the knife holes to remove clothing.

When EMS providers are at a crime scene, their role is to preserve evidence while providing patient care. This includes minimizing disturbance of physical evidence.

Why D is correct:

When removing clothing, EMTs should cut around holes such as knife or bullet holes, not through them.

This preserves important forensic evidence (e.g., wound patterns, weapon characteristics).

It is a standard evidence-preservation technique taught in EMS.

Why the other options are incorrect:

A. Use gloves to tag possible evidence → EMTs should avoid handling or tagging evidence unless necessary

B. Take pictures to document the scene → EMS providers do not photograph scenes; this is law enforcement’s role

C. Leave a deceased person uncovered → The deceased should be treated with dignity and typically covered unless directed otherwise

Exact Extracts:

“Avoid cutting through holes in clothing; cut around them to preserve evidence.”

“Do not disturb the scene more than necessary.”

“Preserve evidence while providing patient care.”

The first step in hemorrhage control for external bleeding is always direct pressure using gloved hands or dressing. Only if this fails or the bleeding is severe and life-threatening (especially from extremities) should a tourniquet be applied.

Assessing the airway is critical in overall trauma care but not the first priority in isolated extremity hemorrhage. Severity assessment is secondary to bleeding control.

The correct answer is D. Ventricular tachycardia.

When an AED states “shock advised,” it means the device has detected a shockable rhythm, which includes:

Ventricular fibrillation (VF)

Pulseless ventricular tachycardia (VT)

Among the answer choices, the only shockable rhythm listed is ventricular tachycardia.

Why this is correct:

AEDs are specifically programmed to identify rhythms that benefit from defibrillation. According to NREMT and AHA guidelines:

“Shockable rhythms include ventricular fibrillation and pulseless ventricular tachycardia.”

Why the other options are incorrect:

A. Asystole: This is a non-shockable rhythm (flatline). Treatment is CPR and medications, not defibrillation.

B. Atrial fibrillation: This is typically a perfusing rhythm and is not treated with AED shocks in cardiac arrest.

C. Pulseless electrical activity (PEA): Also a non-shockable rhythm; treated with CPR and addressing underlying causes.

Exact Extracts (NREMT-aligned EMT educational references):

“AEDs will advise a shock only for ventricular fibrillation or pulseless ventricular tachycardia.”

“Asystole and pulseless electrical activity are non-shockable rhythms.”

Clinical Priority Summary:

A “shock advised” message always indicates a shockable rhythm, and the only correct option given is ventricular tachycardia, making D the correct answer.

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.

The correct answer is C. Abruptio placenta (placental abruption).

This patient presents with classic signs of placental abruption, especially in the context of trauma:

Severe abdominal pain

History of trauma (MVC)

Uterine contractions

Minimal or concealed vaginal bleeding

Why C is correct (Abruptio placenta):

Placental abruption occurs when the placenta prematurely separates from the uterine wall. It is strongly associated with trauma during pregnancy.

Key features include:

Painful abdomen

Uterine irritability or contractions

Bleeding that may be minimal or concealed

NREMT-aligned guidance states:

“Placental abruption is commonly associated with trauma and presents with abdominal pain and uterine contractions.”

“Bleeding may be minimal because it can be concealed behind the placenta.”

Why the other options are incorrect:

A. Placenta previa: Presents with painless vaginal bleeding, not abdominal pain or contractions.

B. Ruptured uterus: Rare, usually associated with severe trauma or prior uterine surgery; presents with catastrophic signs.

D. Spontaneous abortion: Occurs earlier in pregnancy (typically < 20 weeks), not at 26 weeks.

Exact Extracts:

“Placental abruption presents with abdominal pain and vaginal bleeding following trauma.”

“Bleeding may be concealed and not externally visible.”

“Uterine contractions and tenderness are common findings.”

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.

In pediatric patients, NREMT emphasizes that hypotension is a late and ominous sign of shock. Children compensate well and may maintain blood pressure until shock is severe.

Option C (Tachypnea) is the earliest and most reliable indicator of hypovolemic shock in children. Increased respiratory rate reflects metabolic acidosis and compensatory mechanisms for poor perfusion.

Option A may be present but is less specific.

Option B is a very late finding.

Option D indicates decompensated shock and impending cardiovascular collapse.

NREMT stresses early recognition of shock through subtle signs such as tachypnea and tachycardia.

The correct answer is D. Atropine auto-injector.

This patient is exhibiting classic signs of organophosphate or nerve agent poisoning, commonly summarized by the mnemonic SLUDGE:

Salivation (excessive oral secretions)

Lacrimation

Urination (incontinence)

Defecation (bowel incontinence)

Gastrointestinal distress (vomiting)

Emesis

These findings strongly indicate exposure to a cholinergic (nerve) agent, which is a concern in terrorist incidents.

Why Atropine is correct:

Atropine is an anticholinergic medication that blocks the effects of excessive acetylcholine.

It is the primary antidote for organophosphate/nerve agent poisoning.

EMTs may administer it via auto-injector (e.g., DuoDote or Mark I kit) in hazardous materials or terrorism situations.

NREMT-aligned guidance states:

“Organophosphate poisoning presents with excessive secretions and incontinence.”

“Treatment includes administration of atropine to counteract cholinergic effects.”

Why the other options are incorrect:

A. Epinephrine auto-injector: Used for anaphylaxis, not cholinergic poisoning.

B. Naloxone auto-injector: Used for opioid overdose (respiratory depression, pinpoint pupils), not excessive secretions.

C. Activated charcoal: Used for certain ingested toxins, not effective for nerve agent exposure and contraindicated with vomiting.

Exact Extracts (NREMT-aligned EMT educational references):

“SLUDGE: salivation, urination, defecation, GI distress, emesis.”

“Atropine is used to treat organophosphate poisoning.”

“Nerve agents cause excessive cholinergic stimulation.”

Clinical Priority Summary:

The patient’s symptoms clearly indicate nerve agent exposure, and the appropriate treatment is atropine, making D the correct answer.

NREMT distinguishes mild versus severe airway obstruction primarily by the patient’s ability to move air. In a mild obstruction, the patient can cough forcefully, speak, and exchange air. A severe obstruction occurs when airflow is critically impaired.

Option A (Ineffective cough) is the key indicator that a mild obstruction has progressed to a severe one. An ineffective or silent cough means the patient can no longer generate enough airflow to clear the obstruction, placing them at imminent risk of hypoxia and cardiac arrest.

Option B is a late sign of hypoxia but does not define severity of obstruction.

Option C is not specific to airway obstruction severity.

Option D indicates a mild obstruction, not severe.

NREMT teaches that once a cough becomes ineffective, immediate airway intervention is required.
