WEST COAST EMT BLOCK 2 STUDY GUIDE
EXAM QUIZZES WITH ANSWERS UPDATED
2026 – 2027 .
nasal cannula - Correct Answer -An oxygen-delivery device in which oxygen flows through
two small, tubelike prongs that fit into the patient's nostrils
delivers 24% to 44% supplemental oxygen, depending on the flow rate.
1-6 or 1-4 L/min
A BVM bag will hold between _____ and _____ mL of air. - Correct Answer -1000 and 1600
BVM's must have a volume of at least _____mL for newborns and infants. - Correct Answer
-500 (Child BVM)
BVM - Correct Answer -bag valve mask; 15 L/min of 100% oxygen
What is a NRB and when do you use it? - Correct Answer -Nonrebreathing mask used for
patients who are breathing adequately but are suspected of having or showing signs of
hypoxia.
10-15L/min flow rate provides up to 95% inspired oxygen
Venturi mask - Correct Answer -an oxygen-delivery apparatus consisting of a mask with
holes on each side that allow exhaled air to escape and color-coded entrainment ports that are
adjustable to allow regulation of the concentration of oxygen delivered
24%-44% oxygen (medium flow device)
CPAP (continuous positive airway pressure) - Correct Answer -When it's continuously
positive, it means there's air constantly being pushed in, in this case to help keep those
alveolar sacs inflated
Mouth to Mask Ventilation - Correct Answer -technique of artificial ventilation that involves
the use of a pocket face mask with one-way valve to blow air into the mouth of a patient
1
, Capnography - Correct Answer -A noninvasive method to quickly and efficiently provide
information on a patient's ventilatory status, circulation, and metabolism; effectively
measures the concentration of carbon dioxide in expired air over time.
Alkalosis - Correct Answer -The buildup of excess base (lack of acids) in the body fluids. pH
> 7.45
Central chemoreceptors - Correct Answer -brainstem neurons that respond to changes in pH
of cerebrospinal fluid
Located in the medulla
Increase RR and tidal volume to get rid of CO2
Primary mechanism of breathing
Peripheral chemoreceptors - Correct Answer -Receptors in the carotid arteries and the aorta
that monitor blood pH to help regulate ventilation rate.
Back up mechanism of breathing (hypoxic drive)
Cardiac output - Correct Answer -Heart rate x stroke volume, the overall performance of the
heart
Ventilation - Correct Answer -movement of air in and out of the lungs
respiratory system - Correct Answer -Brings oxygen into the body. Gets rid of carbon
dioxide.
Electrical conduction system - Correct Answer -SA node, AV node, Bundle of His, Purkinje
fibers
Pulse locations - Correct Answer -carotid, brachial, radial, femoral, popliteal, posterior tibial,
dorsalis pedis
Dermis - Correct Answer -Inner layer of skin
