Once a candidate gets the correct answers, the computer will automatically enter more difficult questions to continue testing the candidate's skill level. The number of items a candidate can expect from the EMT exam will be between 70 and 120. Each exam will have between 60 and 110 “live” elements that will be counted towards the final score. The exam will also include 10 pilot questions that do not affect the final score. The maximum time allowed to complete the exam is 2 hours. To pass the exam, candidates must meet a standard skill level. The standard of success is defined by the ability to provide safe and effective entry-level emergency medical care.

A program whose efforts are to limit the effects of an injury or illness that you cannot completely prevent is called
Answer: B
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Secondary preventionfocuses onearly detection and interventionto reduce the severity or impact of an illness or injury that has already occurred or is inevitable. Examples in EMS include:
* AED deployment in public
* Stroke recognition training
* Early CPR
Primary preventionaims to stop the injury from occurring at all (e.g., vaccination, seatbelts). "Reactive" and
"proactive" are not recognized formal categories in EMS public health strategy.

NEW QUESTION # 44
A 19-year-old patient has received multiple stab wounds. The patient is unresponsive. The vital signs are BP
82/60, P 116, R 28, and SpO2 86%. Which substance would the EMT expect to increase in the patient's body?
Answer: A
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
The patient is in hypoperfusion (shock) from blood loss. In shock states, tissues are deprived of oxygen, leading to anaerobic metabolism, which produces lactic acid as a byproduct. This causes metabolic acidosis, which is a critical sign of systemic oxygen debt.
Carbon dioxide rises with respiratory failure, but lactic acid is a more specific indicator of cellular hypoxia.

NEW QUESTION # 45
A 23-year-old male fell down a flight of stairs, struck his head, and briefly lost consciousness. He opens his eyes when you ask him questions, knows his name, but doesn't know where he is or what happened.
He is able to squeeze your hands on command. What is his Glasgow Coma Score?
Answer: D
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Use theGlasgow Coma Scale (GCS)to calculate:
* Eye Opening (E):Opens to speech = 3
* Verbal Response (V):Confused but appropriate words = 4
* Motor Response (M):Obeys commands = 6Total = 3 + 4 + 6 = 13
However, thequestion states he opens eyes to voice, knows name (orientation to person), and follows commands- this would mean:
* Eye = 3
* Verbal = 5(Oriented to person, but disoriented to place/time)
* Motor = 6
Correct Total: 14

NEW QUESTION # 46
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.
Answer: B,E,F
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
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 areindications, not contraindications, for CPAP. Pulse rate does not influence CPAP use directly.

NEW QUESTION # 47
What components are necessary to maintain adequate perfusion? Select the three correct options.
Answer: A,B,E
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Perfusionrefers to delivery of oxygen and nutrients to tissues. It depends on three essential components:
* Patent airway: Ensures oxygen reaches lungs
* Intact microcirculation: Capillary-level exchange must function
* Sufficient blood volume: Maintains blood pressure and oxygen transport Hypoxic drive relates toCOPD physiology, not perfusion.High alveolar pressure(like from CPAP) may impede venous return, and alow ventilation-perfusion ratiomeans poor oxygenation efficiency, which negatively affects perfusion.
