2024 JBL MODULE 2 PRACTICEEXAM WITH CORRECT ANSWERS
A 39-year-old male sustained a stab wound to the groin during an altercation
at a bar. As you approach the patient, you note that he is conscious. He is
screaming in pain and is attempting to control the bleeding, which is bright
red and spurting from his groin area. You should:
A. ensure that his airway is patent.
B. apply direct pressure to the wound.
C. elevate his legs and keep him warm.
D. administer 100% supplemental oxygen. - CORRECT-ANSWERSB. apply
direct pressure to the wound.
A palpable pulse is created by:
A. electrical conduction in the heart producing ventricular contraction.
B. the pressure that is caused when venous blood returns to the heart.
C. the pressure of circulating blood against the walls of the arteries.
D. pressure waves through the arteries caused by cardiac contraction. -
CORRECT-ANSWERSD. pressure waves through the arteries caused by
cardiac contraction.
Which of the following structures is contained within the mediastinum?
A. Esophagus
B. Bronchioles
C. Lungs
D. Larynx - CORRECT-ANSWERSA. Esophagus
Which of the following would cause an increase in the amount of exhaled
carbon dioxide?
A. Excessive ventilation
B. Increased cardiac output
C. Cardiopulmonary arrest
D. Anaerobic metabolism - CORRECT-ANSWERSB. Increased cardiac output
,While eating dinner, your partner suddenly grabs his throat and has a
panicked look on his face. He has a weak cough, faint inspiratory stridor, and
cyanosis around the lips. You should:
A. place him in a supine position and open his airway.
B. encourage him to cough as forcefully as he can.
C. stand behind him and administer abdominal thrusts.
D. deliver up to five back blows and reassess him. - CORRECT-ANSWERSC.
stand behind him and administer abdominal thrusts.
While providing CPAP to a patient in severe respiratory distress, you note
that his heart rate has increased by 20 beats/min. He is conscious, but is no
longer following verbal commands. You should:
A. remove the CPAP device and ventilate him with a bag-valve mask.
B. decrease the amount of pressure that the CPAP device is delivering.
C. increase the amount of pressure that the CPAP device is delivering.
D. remove the CPAP device and apply oxygen by nonrebreathing mask. -
CORRECT-ANSWERSA. remove the CPAP device and ventilate him with a bag-
valve mask.
With a good mask-to-face seal and an oxygen flow rate of 15 L/min, the
nonrebreathing mask is capable of delivering up to ______% inspired oxygen.
A. 90
B. 80
C. 100
D. 70 - CORRECT-ANSWERSA. 90
Without adequate oxygen, the body's cells:
A. cease metabolism altogether, resulting in carbon dioxide accumulation in
the blood.
B. begin to metabolize fat, resulting in the production and accumulation of
ketoacids.
C. incompletely convert glucose into energy, and lactic acid accumulates in
the blood.
D. rely solely on glucose, which is completely converted into adenosine
triphosphate. - CORRECT-ANSWERSC. incompletely convert glucose into
energy, and lactic acid accumulates in the blood.
You and your partner are caring for a critically injured patient. Your partner is
controlling severe bleeding from the patient's lower extremities as you
attempt ventilations with a bag-valve mask. After repositioning the mask
several times, you are unable to effectively ventilate the patient. You should:
Select one:
, A. continue attempted ventilations and transport immediately.
B. suction the patient's airway for 30 seconds and reattempt ventilations.
C. hyperextend the patient's head and reattempt ventilations.
D. begin ventilations using the mouth-to-mask technique. - CORRECT-
ANSWERSD. begin ventilations using the mouth-to-mask technique.
You are ventilating a 40-year-old uninjured man who is apneic but has a
pulse. When your partner reassesses his blood pressure, she notes that it
has decreased significantly from previous readings. You should:
A. increase the rate at which you are ventilating and reassess his blood
pressure.
B. perform a head-to-toe assessment to look for signs of bleeding.
C. reduce the rate or volume of the ventilations you are delivering.
D. increase the volume of your ventilations and reassess his blood pressure.
- CORRECT-ANSWERSC. reduce the rate or volume of the ventilations you are
delivering
You are ventilating an apneic woman with a bag-valve mask. She has
dentures, which are tight fitting. Adequate chest rise is present with each
ventilation, and the patient's oxygen saturation reads 96%. When you
reassess the patency of her airway, you note that her dentures are now
loose, although your ventilations are still producing adequate chest rise. You
should:
A. remove her dentures at once and increase the rate and volume of your
ventilations.
B. attempt to replace her dentures so that they fit tightly and resume
ventilations.
C. remove her dentures, resume ventilations, and assess for adequate chest
rise.
D. leave her dentures in place, but carefully monitor her for an airway
obstruction. - CORRECT-ANSWERSC. remove her dentures, resume
ventilations, and assess for adequate chest rise.
Your protocols state that during the first few minutes of working on a cardiac
arrest patient, you should provide passive ventilation. This means that you
will:
A. deliver positive-pressure ventilation at rate of only 5 or 6 breaths/min.
B. ventilate with a bag-valve mask that is not attached to oxygen.
C. time your positive-pressure ventilations to occur during chest recoil.
D. allow recoil of the chest between compressions to draw air into the lungs.
- CORRECT-ANSWERSD. allow recoil of the chest between compressions to
draw air into the lungs.
