Free NREMT EMT Practice Exam with Questions & Answers

The correct answers are C. Bradycardia and E. Widening pulse pressure.

This question is based on recognizing increased intracranial pressure (ICP), specifically components of Cushing’s reflex (Cushing’s triad).

Cushing’s triad includes:

Bradycardia

Hypertension with widening pulse pressure

Irregular respirations

Why C is correct (Bradycardia):

As ICP increases, pressure on the brainstem leads to:

Vagal stimulation

Slowing of the heart rate

NREMT-aligned guidance:

“Bradycardia is a late sign of increased intracranial pressure.”

Why E is correct (Widening pulse pressure):

ICP causes:

Increased systolic pressure

Decreased diastolic pressure

This results in a widening pulse pressure, a hallmark of worsening ICP.

Guidelines state:

“Hypertension with widening pulse pressure is associated with increased intracranial pressure.”

Why the other options are incorrect:

A. Tachypnea: Early stress response; ICP causes irregular, not simply rapid breathing.

B. Hypotension: Opposite of ICP findings; suggests shock.

D. Muffled heart sounds: Associated with cardiac tamponade, not ICP.

Exact Extracts:

“Cushing’s triad includes bradycardia, hypertension, and irregular respirations.”

“Widening pulse pressure is a sign of increased intracranial pressure.”

“These are late signs indicating possible brain herniation.”

Comprehensive and Detailed Explanation (Based on NREMT standards):

When a previously choking adult becomes unresponsive, NREMT guidelines require the EMT to immediately begin the cardiac arrest sequence.

Option A (Check for a pulse) is correct because determining pulselessness directs the next intervention.

Option B (Begin chest compressions) is correct because chest compressions are initiated if the patient is pulseless and unresponsive. Compressions may also help dislodge the foreign body.

Option C is incorrect because the airway is checked only after compressions begin and ventilations are attempted.

Option D is incorrect because ventilations are attempted after compressions, with airway checks between cycles.

Option E is inappropriate for an unresponsive adult.

NREMT emphasizes following BLS algorithms precisely for airway obstruction leading to unresponsiveness.

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.

Albuterol, a common beta-2 adrenergic agonist used in inhalers, stimulates bronchial smooth muscle relaxation. However, stimulation of beta receptors can also produce systemic effects such as:

Tachycardia (due to beta-1 cross-reactivity)

Nervousness (from central stimulation)

Coughing (a local airway response)

Confusion and drowsiness are not typical side effects of beta-agonists. Hypotension is rare unless severe overdose occurs.

Comprehensive and Detailed Explanation:

The correct answer is A. secondary prevention.

Key Concept: Levels of Prevention

EMS and public health recognize three levels of prevention:

Primary prevention

Prevents the injury or illness before it occurs

Example: seat belts, vaccinations

Secondary prevention ✅

Reduces the effects of an illness or injury that has already occurred or cannot be fully prevented

Focuses on early detection and limiting severity

Tertiary prevention

Reduces long-term complications and disability

Example: rehabilitation

Why A is correct (Secondary Prevention):

The question states:“limit the effects of an injury or illness that you cannot completely prevent”

This directly matches the definition of secondary prevention, which aims to:

Minimize severity

Detect problems early

Prevent worsening

Why the other options are incorrect:

B. Primary prevention❌ Focuses on stopping the problem before it starts, not limiting effects

C. Reactive prevention❌ Not a recognized EMS/public health category

D. Proactive prevention❌ Also not a formal classification in EMS prevention models

Key Takeaway:

Primary = prevent occurrence

Secondary = limit effects (correct answer)

Tertiary = reduce long-term impact

The correct answer is D because the first appropriate action is to address the error directly and immediately by having your partner correct the patient care report . EMS documentation guidance used in national EMT education is clear that the PCR must be accurate and factual , and specifically states that providers must not chart treatments that were not actually given . For example, official EMT instructional guidance says that if a treatment such as oxygen was overlooked, do not document that it was given .

Because the false entry is being made at the time of documentation, the first step is to stop the inaccurate charting and get it corrected. If your partner refuses, then the issue should be escalated through the chain of command. Accurate PCR documentation is part of patient care, legal documentation, and quality assurance in EMS.

NREMT standards emphasize scene safety, infection control, and proper sharps handling to reduce the risk of occupational exposure. A contaminated needle left in a mattress presents a serious needlestick hazard to EMS providers, hospital staff, and patients.

Option B is correct because the appropriate action is to carefully remove the needle and immediately dispose of it in an approved sharps container. This follows OSHA and NREMT infection-control principles, which state that sharps must be disposed of promptly in puncture-resistant containers without unnecessary handling.

Option A is incorrect because recapping needles is strictly prohibited under standard precautions. Recapping significantly increases the risk of accidental needlestick injuries and violates established safety guidelines.

Option C is incorrect because confronting a paramedic in front of a patient is unprofessional and undermines team dynamics. Any concerns regarding unsafe practices should be addressed privately and through appropriate supervisory channels.

Option D is incorrect because ignoring an exposed sharp creates an ongoing safety hazard and fails the EMT’s responsibility to maintain a safe environment.

In summary, NREMT expects EMTs to act proactively to reduce hazards, follow standard precautions, and safely dispose of sharps without recapping or delay. Removing the needle carefully and placing it in a sharps container is the safest and most appropriate response.

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.”

Compared to adults, pediatric patients have:

A proportionately larger tongue, which increases the risk of airway obstruction

A larger occiput, which causes natural neck flexion when lying supine, potentially occluding the airway

This anatomical difference is why EMS providers often use a shoulder roll instead of a head tilt to maintain a neutral airway in infants and toddlers.

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.
