A patient who to takes an occasional gasping breath after their heart has
stopped has:
A: agonal respirations.
B: ataxic respirations.
C: apneic respirations.
D: hypoxic respirations. – ANSWER- A: agonal respirations.
Rationale: Agonal respirations are shallow, inadequate respirations
that occur after the heart has stopped.
When inserting a nasopharyngeal airway, it is important to do all the
following except:
A: Measure the size from the tip of the nose to the earlobe.
B: Ensure that the bevel faces the septum when inserting into the right
nare.
C: Insert with a constant rotating motion.
D: Lubricate the airway with a water-based lubricant. – ANSWER- C:
Insert with a constant rotating motion.
Rationale: The device should be rotated 180 degrees if placed in the
left nare, and not at all in the right nare.
If a D-sized oxygen cylinder contains 300 L of oxygen and is at 2,000
PSI at the start of call, the best estimate for the amount of time a patient
can receive 15 L\/min with a nonrebreathing mask is:
A: 10 minutes.
B: 20 minutes.
C: 30 minutes.
D: 40 minutes. – ANSWER- B: 20 minutes.
Rationale: 20 minutes. This can be calculated either by dividing 15
L\/min into 300 L, for a result of 20 minutes, or by using the psi
constant for a D cylinder, which is 0.16. The calculation would then
be (2,000 -200) x 0.16 \/15 L\/min = 19.2, which is approximately 20
minutes.
Properly performed suctioning of a patient may still cause:
A: hypoxia.
B: vomiting.
C: gastric distention.
D: aspiration. – ANSWER- B: vomiting.
Rationale: Vomiting maybe caused even when the skill is performed
correctly. Hypoxia can be prevented if the EMT-B only uses the
machine for 15 seconds or less on adult patients. Aspiration and
gastric distention are not caused by suctioning.
When using a bag-valve-mask device, the key finding to observe to
assure adequate ventilation is:
A: three seconds between squeezing the bag and lifting the mask off the
face.
B: the patient’s weight in kilograms.
C: good chest rise and fall.
D: the location of the patient’s cricoid cartilage. – ANSWER- C: good
chest rise and fall.
Rationale: Good chest rise and fall is the most important method to
measure the patient’s ventilations.
The most common complication of the flow-restricted, oxygen-powered
ventilation device is:
A: pneumothorax.
B: hypoventilation.
C: cricoid pressure.
D: gastric distention. – ANSWER- D: gastric distention.
Rationale: Medical literature indicates that gastric distention is the
most common complication, however, patients with COPD maybe at
greater risk for a pneumothorax.
What is the rate of breaths per minute for an adult?
A: 10-18
B: 12-20
C: 15-25
D: 8-16 – ANSWER- B: 12-20
What is respiration?
A: the way the body uses carbon dioxide to maintain metabolism.
B: the process by which the body uses oxygen and expels carbon
dioxide.
C: when oxygen is perfused with the blood and carbon monoxide is
removed.
D: the process by which the body removes excess moisture and cools
the body through evaporation. – ANSWER- B: the process by which the
body uses oxygen and expels carbon dioxide.
You should NOT be concerned about the following symptoms when you
suspect breathing problems in a pediatric patient?
A: grunting at the end of respirations.
B: the patient is breathing at 65 breaths per minute.
C: nasal flaring<\/p>\n\n\n\n
