Rationales Included
,1 Which of the following is considered an early sign of Restlessness
hypoxia in an adult patient?
Restlessness
Cyanosis
Weak, thready pulse
Poor skin turgor
2 A 28-year-old female is involved in a motor vehicle Use the head-tilt/chin-lift maneuver to open her airway
accident. She is unresponsive and apneic. All attempts at
opening her airway using the jaw-thrust maneuver have
failed. What is the most appropriate next step?
Ventilate her with a bag-valve mask (BVM) and reservoir
bag
Use the head-tilt/chin-lift maneuver to open her airway
Attempt mouth-to-mask ventilation
Insert two nasal airways and apply high-flow oxygen
therapy
3 Under what circumstances should a patient's dentures If the dentures obstruct the airway or interfere with ventilation
be removed in order to provide proper assisted
ventilations?
If an oropharyngeal airway is being placed
If the dentures make the patient uncomfortable
If the dentures obstruct the airway or interfere with
ventilation
If severe head trauma has occurred
,4 You are assessing the vital signs of a child at a local Respirations 20 breaths per minute, pulse 98 beats per minute, BP 104/73 mmHg
elementary school. Which of the following would be
considered a normal set of vitals for a healthy eight-year-
old child?
Respirations 12 breaths per minute, pulse 130 beats per
minute, BP 100/72 mmHg
Respirations 35 breaths per minute, pulse 58 beats per
minute, BP 128/66 mmHg
Respirations 16 breaths per minute, pulse 58 beats per
minute, BP 190/70 mmHg
Respirations 20 breaths per minute, pulse 98 beats per
minute, BP 104/73 mmHg
5 A responsive adult patient complaining of shortness of Use a nasal cannula with supplemental oxygen flowing at six liters per minute
breath could benefit from oxygen delivered via a
nonrebreather mask, but he is unable to tolerate a mask
on his face. What is the most appropriate next step?
Insert a nasopharyngeal airway and a nasal cannula
Avoid providing oxygen altogether
Use a nasal cannula with supplemental oxygen flowing at
six liters per minute
Provide artificial ventilations via a manually triggered
ventilation device
6 During the initial assessment of a semiconscious A partially obstructed airway
patient's airway, snoring respirations are heard. What are
these respirations an indication of?
The bronchi are constricted
Mucus or secretions in the larger airway
Fluid in the upper airway
A partially obstructed airway
7 What is the correct procedure for removing oral Logroll the patient to his/her side and clear the mouth carefully with a gloved
secretions from the oropharynx of a conscious patient finger
without visible foreign bodies and no suspected C-spine
injury?
Turn the patient's head to the side, open the mouth, insert
the catheter and suction in a circular motion during
withdrawal for no more than 15 seconds
Insert an oropharyngeal airway to ensure a patent airway
Logroll the patient to his/her side and clear the mouth
carefully with a gloved finger
Continuously ventilate the patient to ensure appropriate
oxygenation
, 8 Which of the following happens during the inhalation The diaphragm and the intercostal muscles contract, enlarging the chest cavity
phase of ventilation?
The diaphragm relaxes, decreasing the chest cavity
The diaphragm and the intercostal muscles contract,
enlarging the chest cavity
The diaphragm contracts, moving upward, forcing the
lungs to expand outward
The diaphragm contracts and the intercostal muscles
relax, enlarging the chest cavity
9 An adult trauma patient is unresponsive but breathing at Open the airway using the jaw-thrust maneuver while maintaining inline cervical
a rate of 12 breaths per minute spontaneously. The patient spine stabilization, and apply an oropharyngeal airway
is snoring and his chest is not rising adequately. Which of
the following is the most appropriate intervention?
Open the airway using the jaw-thrust maneuver while
maintaining inline cervical spine stabilization, and apply
an oropharyngeal airway
Open the airway using the jaw-thrust maneuver while
maintaining inline cervical spine stabilization, and provide
assisted ventilations using a bag-valve mask
Open the airway using a head-tilt/chin-lift maneuver while
maintaining inline cervical spine stabilization, and apply
an oropharyngeal airway
Open the airway using a head-tilt/chin-lift maneuver while
maintaining inline cervical spine stabilization, and apply a
nasopharyngeal airway
10 An adult patient has greater than 36% total body Provide airway control and high-flow oxygen therapy
surface area burns, mainly affecting his back and lower
extremities. After the burning process has been stopped
and smoldering clothing removed, which of the following
should be the initial treatment for this patient?
Cover the burn area in antiseptic to prevent infection
Provide airway control and high-flow oxygen therapy
Assess the patient for the possibility of other injuries
Immerse the patient in cool water or saline solution
11 A 13-year-old near-drowning patient has inadequate The airway is obstructed due to water
respirations and requires artificial ventilation. Which of the
following is the most likely cause of resistance felt on
ventilation?
The airway is obstructed due to water
The patient has chronic obstructive pulmonary disease
(COPD)
The airway is obstructed due to a swollen epiglottis
The trachea has collapsed due to the near-drowning
