Pass Study Guide
1. A 67-year-old male is found unconscious. You hear snoring respirations. What is
the most likely cause?
A) Fluid in the lungs
B) Upper airway obstruction by the tongue
C) Bronchoconstriction
D) Swelling of the epiglottis
Answer: B) Upper airway obstruction by the tongue
Explanation: Snoring is the classic sound of the tongue partially obstructing the oropharynx
in a patient with a decreased level of consciousness.
2. You are treating a patient with a suspected spine injury. What is the preferred
method for opening the airway?
A) Head-tilt, chin-lift
B) Jaw-thrust maneuver
C) Cross-finger technique
D) Oropharyngeal suctioning
Answer: B) Jaw-thrust maneuver
Explanation: The jaw-thrust opens the airway without extending the neck, protecting the
cervical spine.
3. What is the correct rate for artificial ventilations in an adult patient who has a pulse
but is not breathing?
A) 1 breath every 3 seconds
B) 1 breath every 6 seconds
C) 1 breath every 10 seconds
D) 2 breaths every 30 seconds
Answer: B) 1 breath every 6 seconds
,Explanation: AHA guidelines recommend 10–12 breaths per minute (one every 5–6
seconds) for an adult with a pulse.
4. A patient presents with a harsh, high-pitched sound on inspiration. This is called:
A) Wheezing
B) Rales
C) Stridor
D) Rhonchi
Answer: C) Stridor
Explanation: Stridor indicates an upper airway obstruction, often due to swelling or a
foreign body.
5. You have just suctioned a patient's airway. What should you do next?
A) Suction for another 15 seconds
B) Oxygenate the patient for 2 minutes
C) Insert a King airway
D) Check for a pulse
Answer: B) Oxygenate the patient for 2 minutes
Explanation: Suctioning removes oxygen as well as fluids; you must pre-oxygenate or re-
oxygenate between attempts.
6. Which of the following is an "early" sign of hypoxia?
A) Cyanosis
B) Bradycardia
C) Restlessness and anxiety
D) Hypotension
Answer: C) Restlessness and anxiety
Explanation: The brain is highly sensitive to oxygen loss; altered mental status or agitation
is an early indicator.
7. A 55-year-old female is complaining of "crushing" chest pain. She has her own
Nitroglycerin. What is the requirement to assist her with it?
A) Her BP must be above 100 systolic
B) She must be unconscious
C) She must have already taken her Aspirin
D) You must call the hospital after giving it
Answer: A) Her BP must be above 100 systolic
Explanation: Nitroglycerin is a vasodilator; giving it to a hypotensive patient can cause a
dangerous drop in blood pressure.
,8. You arrive on scene for a 60-year-old male in cardiac arrest. An AED is available.
What is your first action?
A) Perform 5 minutes of CPR
B) Turn on the AED
C) Deliver 2 rescue breaths
D) Check a pulse for 30 seconds
Answer: B) Turn on the AED
Explanation: For a witnessed arrest with an AED immediately available, the priority is to
turn it on and apply pads as soon as possible.
9. While the AED is analyzing the heart rhythm, you should:
A) Continue chest compressions
B) Ensure no one is touching the patient
C) Provide ventilations
D) Prepare the suction unit
Answer: B) Ensure no one is touching the patient
Explanation: Movement can interfere with the AED's ability to accurately analyze the
electrical activity of the heart.
10. After the AED delivers a shock, what is your next step?
A) Re-check the pulse
B) Immediately resume chest compressions
C) Wait for the AED to analyze again
D) Check for breathing
Answer: B) Immediately resume chest compressions
Explanation: You should not stop to check a pulse after a shock; you immediately begin
the next 2-minute cycle of CPR.
11. A 45-year-old male is diaphoretic and complaining of chest pain radiating to his
left jaw. What is the most important medication to give first?
A) Nitroglycerin
B) Epinephrine
C) Aspirin
D) Albuterol
Answer: C) Aspirin
Explanation: Aspirin prevents further platelet aggregation (clotting) and is shown to
decrease mortality in heart attacks.
, 12. Which heart chamber pumps oxygenated blood to the rest of the body?
A) Right Atrium
B) Right Ventricle
C) Left Atrium
D) Left Ventricle
Answer: D) Left Ventricle
Explanation: The left ventricle is the high-pressure pump that sends blood through the
aorta to the systemic circulation.
13. A patient is in "Shock" and has a blood pressure of 80/40. What stage of shock
are they in?
A) Compensated
B) Decompensated
C) Irreversible
D) Psychogenic
Answer: B) Decompensated
Explanation: Once the blood pressure drops (hypotension), the body's compensatory
mechanisms have failed.
14. A 19-year-old male was stabbed in the chest. You note a "sucking" sound. What is
the priority intervention?
A) Apply a tourniquet
B) Cover with an occlusive dressing taped on 3 sides
C) Perform chest compressions
D) Pack the wound with gauze
Answer: B) Cover with an occlusive dressing taped on 3 sides
Explanation: This creates a one-way valve that allows air to escape the chest but not enter
it.
15. A patient has an obvious deformity to the mid-shaft femur. You note the leg is
shortened and rotated. What is the best splint?
A) Rigid splint
B) Traction splint
C) Air splint
D) Vacuum splint
Answer: B) Traction splint
Explanation: Traction splints are specifically for isolated, mid-shaft femur fractures to
counteract muscle spasms and prevent blood loss.
