NREMT Emergency Medical Technicians Exam Sample Questions (Q175-Q180):

NEW QUESTION # 175
An EMT is using a BVM to ventilate a 28-year-old patient with asthma. The patient is unresponsive, and their vital signs are BP 70/40, P 142, R 8, and SpO2 89% on room air. The patient is becoming increasingly difficult to ventilate. What should the EMT do next?

A. Apply high-flow oxygen via non-rebreather mask
B. Decrease the rate of ventilations
C. Ventilate the patient more forcefully
D. Place the patient on CPAP

Answer: B

Explanation:
In patients with asthma experiencing respiratory failure, improper ventilation (especially excessive rates) can lead to air trapping and increased intrathoracic pressure, reducing venous return and worsening hypotension.
The correct technique is to ventilate slowly to allow full exhalation - around 1 breath every 5-6 seconds for adults.
CPAP is contraindicated in unresponsive patients who cannot maintain their own airway. A non-rebreather mask would be insufficient for an unresponsive patient, and forceful ventilation risks barotrauma.

NEW QUESTION # 176
In an MCI, a 32-year-old patient is unresponsive and not breathing. Which of the following interventions should the EMT perform first?

A. Provide mechanical ventilations.
B. Administer chest compressions.
C. Open the airway.
D. Assess their blood pressure.

Answer: C

Explanation:
The correct answer is B because during mass-casualty incident (MCI) triage , the EMT follows a rapid assessment approach (such as START triage). For an unresponsive, non-breathing patient, the first step is to open the airway to determine if breathing resumes.
NREMT-aligned triage principles emphasize that if the patient begins breathing after airway repositioning
, they are categorized as immediate. If they do not begin breathing , they are tagged as deceased/expectant, and no further resuscitation (like CPR) is initiated during triage.
Therefore, airway opening is the first and most critical step in this scenario.

NEW QUESTION # 177
A 44-year-old patient is unresponsive, and an EMT checks for a pulse prior to applying an AED. Which of the following shockable rhythms, ventricular fibrillation or ventricular tachycardia, if either, may still produce a pulse in this patient?

A. Neither a shockable rhythm
B. Both shockable rhythms
C. Ventricular tachycardia only
D. Ventricular fibrillation only

Answer: C

Explanation:
The correct answer is B. Ventricular tachycardia only.
There are two primary shockable rhythms in cardiac arrest:
Ventricular fibrillation (VF)
Ventricular tachycardia (VT)
However, only one of these may still produce a pulse under certain conditions.
Why B is correct:
Ventricular tachycardia (VT) can occur with or without a pulse.
In some cases, VT allows the heart to generate enough cardiac output to produce a palpable pulse (this is called stable or unstable VT with a pulse).
Therefore, VT is the only shockable rhythm that may still have a pulse.
Why the other options are incorrect:
A). Ventricular fibrillation only # VF produces no organized cardiac activity, therefore no pulse C). Both shockable rhythms # Incorrect because VF never produces a pulse D). Neither a shockable rhythm # Incorrect because VT can produce a pulse Exact Extracts:
"Ventricular fibrillation results in no effective cardiac output and no pulse."
"Ventricular tachycardia may be present with or without a pulse."
"Pulseless ventricular tachycardia and ventricular fibrillation are treated with defibrillation." References:

NEW QUESTION # 178
A patient has heart failure with pulmonary edema. They have shortness of breath, and crackles are present in both lungs. The patient is nauseated and has vomited once. The vital signs are BP 90/40, P 110, R 10, and SpO# 89% on room air. Which of the following signs or symptoms prevent the EMT from using CPAP?
Select the three correct options.

A. Oxygen saturation
B. Crackles in both lungs
C. Respiratory rate
D. Blood pressure
E. Nausea and vomiting
F. Pulse rate

Answer: C,D,E

Explanation:
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.

NEW QUESTION # 179
What phase of an explosion is most likely to produce injuries to the gas-containing organs of the body?

A. Secondary
B. Tertiary
C. Primary
D. Quaternary

Answer: C

Explanation:
The correct answer is A because primary blast injuries are caused by the blast wave itself , and that pressure wave most strongly affects gas-containing organs such as the lungs, ears, and bowel .
Authoritative blast-injury references specifically state that primary blast injury damages gas-filled organs, while the other blast phases involve fragments, body displacement, burns, or other associated effects. ( NCBI )
