NEW QUESTION # 74
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?
Answer: D
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
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 # 75
While responding to an emergency, a car is tailgating the ambulance. Which of the following actions should the EMT take?
Answer: D
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
In situations where a vehicle is tailgating an emergency unit, tapping the brakes briefly is a standard defensive driving maneuver to alert the driver behind to increase distance. It is less risky than slowing dramatically or pulling over, which could endanger crew or delay response.
Speeding up could reduce your reaction window or increase accident risk. EMS operators must follow safe driving practices per NFPA 1002 and DOT Emergency Vehicle Operation Guidelines.

NEW QUESTION # 76
What is the most effective way an EMT can protect themselves from spreading infectious diseases?
Answer: A
Explanation:
The correct answer is C. Frequent hand washing.
While all listed options contribute to infection control, hand hygiene is the single most effective method for preventing the spread of infectious diseases in EMS and healthcare settings.
Why C is correct:
Hands are the primary mode of transmission for pathogens
Frequent hand washing removes microorganisms before they spread to:
Patients
Equipment
Other surfaces
NREMT-aligned guidance states:
"Hand washing is the most effective way to prevent the spread of infection."
"Perform hand hygiene before and after every patient contact."
Why the other options are incorrect:
A). Using proper PPEImportant, but secondary to hand hygiene; PPE can still become contaminated B). Washing uniforms dailyGood practice, but not the most effective immediate prevention method D). Maintaining current vaccinesImportant for provider protection, but does not directly prevent day-to-day transmission Exact Extracts (NREMT-aligned EMT educational references):
"The most important step in preventing disease transmission is proper hand hygiene."
"Wash hands before and after patient contact."
"Hand hygiene reduces the spread of pathogens."
Clinical Priority Summary:
Although PPE and vaccines are important, frequent hand washing is the most effective and essential method for preventing disease transmission, making C the correct answer.
