Complete Clinical Practice Questions, Correct Answer Keys, and Detailed
Rationales
Document Summary: This study guide is structured for candidates preparing for the National Registry of
Emergency Medical Technicians (NREMT) cognitive examination. It incorporates high-yield multiple-choice
questions across all core operational and clinical domains: Airway, Respiration & Ventilation, Cardiology &
Resuscitation, Trauma, Medical & Obstetrics/Gynecology, and EMS Operations. All items feature verified
answers and step-by-step clinical rationales aligned with current emergency care guidelines.
, DOMAIN 1: AIRWAY, RESPIRATION & VENTILATION
QUESTION 1
A 56-year-old male with a history of asthma presents with severe respiratory distress, audible wheezing,
and an SpO2 of 86% on room air. He is awake but only able to speak in single words. Which of the
following is the most appropriate initial oxygenation intervention?
A. Nasal cannula at 2 L/min
B. Non-rebreather mask at 15 L/min
C. Bag-valve-mask with supplemental oxygen at 15 L/min
D. Simple face mask at 6 L/min
Correct Answer: B
Explanation: A non-rebreather mask (NRB) supplying 10–15 L/min provides high-concentration oxygen (up to 90%) and
is indicated for patients exhibiting signs of severe respiratory distress who retain adequate tidal volume and respiratory
rate. If the patient's breathing becomes inadequate (shallow or abnormally slow), positive pressure ventilation with a BVM
would become necessary.
QUESTION 2
While performing suctioning on an unresponsive adult patient with thick secretions in the upper airway,
what is the maximum length of time suction should be applied in a single pass?
A. 5 seconds
B. 10 seconds
C. 15 seconds
D. 20 seconds
Correct Answer: C
Explanation: Suctioning removes air alongside secretions, which can cause significant hypoxia. In adult patients,
suctioning must be limited to no more than 15 seconds per pass (10 seconds for children, 5 seconds for infants). Suction
should only be applied upon withdrawing the catheter.
