Question 1
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.
Answer: B
Rationale: The patient is experiencing severe, arterial spurting hemorrhage,
which constitutes an immediate life threat (exsanguination). In primary trauma
care, an active, massive external hemorrhage must be controlled immediately
using direct pressure before moving on to other systemic assessments, as the
patient can bleed out rapidly.
Question 2
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.
Answer: D
Rationale: A pulse is the palpable rhythmic expansion and contraction of an
artery. It is generated by the pressure waves of blood traveling through the
systemic arterial system following the forceful ejection of stroke volume during
ventricular contraction (systole).
Question 3
Which of the following descriptions best outlines the anatomical location of the carotid
artery?
A. Located on the dorsum of the foot lateral to the extensor tendon.
B. Located in the neck, lateral to the trachea in the groove.
C. Located on the medial aspect of the arm between the biceps and triceps.
D. Located posterior to the medial malleolus of the ankle.
Answer: B
Rationale: The carotid artery is a major central artery located bilaterally in the
neck, running lateral to the trachea within the carotid groove. It is easily palpable
and serves as a primary site to assess central pulse quality in unresponsive
adults.
,Question 4
While performing a primary survey on an unresponsive trauma patient, you note snoring
respirations. Your immediate next action should be to:
A. insert a nasopharyngeal airway immediately.
B. perform a head-tilt, chin-lift maneuver.
C. perform a jaw-thrust maneuver while maintaining manual c-spine stabilization.
D. begin positive-pressure ventilations with a bag-valve mask.
Answer: C
Rationale: Snoring respirations indicate a partial upper airway obstruction,
typically caused by the tongue falling backward against the pharynx. In a trauma
patient with a suspected spinal injury, the jaw-thrust maneuver is the mandatory
manual technique to open the airway without moving the cervical spine.
Question 5
What is the primary function of the platelets within the circulating blood volume?
A. Transporting oxygen and carbon dioxide molecules to and from tissues.
B) Defending the body against systemic bacterial and viral pathogens.
C. Initiating the coagulation cascade and forming a structural blood clot.
D. Maintaining the osmotic pressure and fluid balance of plasma.
Answer: C
Rationale: Platelets (thrombocytes) are tiny cellular fragments essential for
homeostasis. When a blood vessel is injured, platelets aggregate at the site to
form a platelet plug and release chemical factors that initiate the clotting cascade
to stop bleeding.
Question 6
A 64-year-old female presents with severe chest pain and diaphoresis. You prepare to
assist her with her prescribed sublingual nitroglycerin. Before administering this
medication, you must verify that her systolic blood pressure is at least:
A. 80 mmHg
B. 90 mmHg
C. 100 mmHg
D. 120 mmHg
Answer: C
, Rationale: Nitroglycerin is a potent vasodilator that decreases preload and
afterload. To prevent severe, catastrophic hypotension, EMT protocols dictate
that the patient's systolic blood pressure must be at least 100 mmHg prior to
administering each dose.
Question 7
Which layer of the skin contains the blood vessels, hair follicles, sweat glands, and
specialized nerve endings?
A. Epidermis
B. Dermis
C. Subcutaneous layer
D. Stratum corneum
Answer: B
Rationale: The skin is composed of distinct layers. The dermis is the thick,
structural inner layer that contains specialized structures such as capillaries,
nerve receptors, hair roots, sebaceous glands, and sweat glands. The outer
epidermis provides a protective, avascular barrier.
Question 8
When evaluating the mechanics of breathing, which physiological event occurs during a
normal, active inhalation?
A. The diaphragm and intercostal muscles relax, decreasing thoracic volume.
B. The diaphragm contracts and moves downward, creating negative intrathoracic
pressure.
C. Intrathoracic pressure rises above atmospheric pressure.
D. The chest wall moves inward to compress the lung structures.
Answer: B
Rationale: Inhalation is an active process driven by muscular contraction. The
diaphragm contracts and flattens downward while the external intercostal
muscles lift the ribs. This expands thoracic volume, creating negative
intrathoracic pressure that draws air into the lungs.
Question 9
An adult patient presents with a respiratory rate of 6 breaths per minute with shallow
