Unit3
1) You have performed a head tilt-chin lift maneuver on a 17-month-old boy and are attempting to
ventilate him with a bag-valve mask. You are experiencing a lot of resistance with each breath and the
chest is barely rising. Prior to attempting ventilations again, you should:
A) ease the head forward a little.
B) tilt the head back further.
C) finger sweep the airway.
D) perform chest thrusts. - correct answer✔️✔️A)
Explanation: CORRECT. The trachea of a small child is more pliable than that of an adult. Exaggerated
flexion of the airway causes the trachea to bend unnaturally and block off the flow of air Page Ref: 212
2) You are aggressively ventilating an adult patient with a bag-valve mask when you notice that his
previously strong pulse is getting weaker. You should:
A) begin chest compressions.
B) reduce the concentration of oxygen.
C) increase the concentration of oxygen.
D) reduce the volume of the ventilations. - correct answer✔️✔️D)
Explanation: CORRECT. Positive pressure ventilation can increase the pressure inside the chest,
inhibiting blood return to the heart. You should ventilate just enough to see the chest rise. Page Ref: 251
3) You are attempting to replace the oxygen cylinder in your truck. After removing the regulator from
the old cylinder, removing the old cylinder, and placing the new cylinder in the oxygen compartment,
you attempt to connect the regulator. The new cylinder is yellow rather than green, but it was stored
, with the green cylinders. You are unable to get the regulator to seat properly and it will not turn. You
should:
A) put the old cylinder back on the truck.
B) attempt to force the regulator onto the cylinder.
C) remove the yellow cylinder and get a green cylinder.
D) replace the oxygen regulator with a new one. - correct answer✔️✔️C)
Explanation: CORRECT. Compressed gases are color coded per the United States Pharmacopoeia, and
oxygen cylinders are always only green or green and white. In addition, gas cylinders are designed to be
used only with gas-specific regulators. In this case, you are attempting to put an oxygen regulator on a
non-oxygen tank. The cylinder should be removed from the truck and replaced with a green oxygen
tank. Page Ref: 266-268
4) You are transporting a 44-year-old female with chest pain and sudden respiratory distress. She is
agitated, anxious, and refuses to have a nonrebreather mask applied. Which of the following is the best
option?
A) Have her breathe into a paper bag to control her hyperventilation.
B) Do not make further attempts to administer oxygen as it will only agitate the patient further.
C) Consult with medical control about restraining the patient.
D) Use a nasal cannula instead. - correct answer✔️✔️D)
Explanation: CORRECT. It is not uncommon for patients in respiratory distress to dislike the thought of a
mask being placed over their mouth and nose; if the patient absolutely refuses, some oxygen from a
nasal cannula is better than none. Page Ref: 276
5) The oxygen flow rate for a nasal cannula should not exceed ________ liters per minute.
