Blood stasis, changes in the vessel wall, and certain medications affect the:

A. white blood cell's ability to fight infection.
B. systolic blood pressure exclusively.
C. ability of red blood cells to carry oxygen.
D. ability of the blood to effectively clot.

D. ability of the blood to effectively clot.

Bleeding from the nose following head trauma:

A. is a sign of a skull fracture and should not be stopped.
B. should be assumed to be caused by a fractured septum.
C. should be controlled by packing the nostril with gauze.
D. is usually due to hypertension caused by the head injury.

A. is a sign of a skull fracture and should not be stopped.

The ability of a person's cardiovascular system to compensate for blood loss is MOST related to:

A. his or her baseline blood pressure.
B. how rapidly he or she bleeds.
C. how fast his or her heart beats.
D. the part of the body injured.

B. how rapidly he or she bleeds.

Whether you are using a commercial device or a stick and triangular bandage as a tourniquet, it is important to remember that:

A. the tourniquet should be applied directly over a joint if possible because this provides better bleeding control.
B. the tourniquet should only be removed at the hospital because bleeding may return if the tourniquet is released.
C. you should try to control the bleeding by applying pressure to a proximal arterial pressure point first.
D. bulky dressings should be securely applied over the tourniquet to further assist in controlling the bleeding.

B. the tourniquet should only be removed at the hospital because bleeding may return if the tourniquet is released.

An organ or tissue may be better able to resist damage from hypoperfusion if the:

A. body's demand for oxygen is markedly increased.
B. systolic arterial blood pressure is at least 60 mm Hg.
C. heart rate is maintained at more than 100 beats/min.
D. body's temperature is considerably less than 98.6°F (37.0°C).

D. body's temperature is considerably less than 98.6°F (37.0°C).

The severity of bleeding should be based on all of the following findings, EXCEPT:

A. systolic blood pressure.
B. the mechanism of injury.
C. poor general appearance.
D. clinical signs and symptoms.

A. systolic blood pressure.

Early signs and symptoms of intra-abdominal bleeding include:

A. bruising only.
B. significant hypotension.
C. pain and distention.
D. widespread ecchymosis.

C. pain and distention.

Most cases of external bleeding from an extremity can be controlled by:

A. elevating the injured extremity.
B. compressing a pressure point.
C. applying local direct pressure.
D. packing the wound with gauze.

C. applying local direct pressure.

Hypovolemic shock occurs when:

A. the clotting ability of the blood is enhanced.
B. at least 10% of the patient's blood volume is lost.
C. the patient's systolic blood pressure is less than 100 mm Hg.
D. the body cannot compensate for rapid blood loss.

D. the body cannot compensate for rapid blood loss.

The smaller vessels that carry blood away from the heart and connect the arteries to the capillaries are called the:

A. arterioles.
B. venules.
C. vena cavae.
D. capillary arteries.

A. arterioles.

External bleeding from a vein is relatively easy to control because:

A. veins hold smaller blood volume.
B. veins are under a lower pressure.
C. blood typically oozes from a vein.
D. veins carry deoxygenated blood.

B. veins are under a lower pressure.

When using a stick and square knot as a tourniquet to control severe bleeding from an amputated arm, the EMT should:

A. cover the tourniquet with a sterile dressing.
B. remove the tourniquet if the bleeding has stopped.
C. twist the stick until the radial pulse disappears.
D. stop twisting the stick when the bleeding stops.

D. stop twisting the stick when the bleeding stops.

If direct pressure with a sterile dressing fails to immediately stop severe bleeding from an extremity, you should apply:

A. additional sterile dressings.
B. a tourniquet proximal to the injury.
C. a splint and elevate the extremity.
D. digital pressure to a proximal artery.

B. a tourniquet proximal to the injury.

In which of the following situations would external bleeding be the MOST difficult to control?

A. carotid artery laceration and a systolic blood pressure of 60 mm Hg
B. antecubital vein laceration and a blood pressure of 138/92 mm Hg
C. jugular vein laceration and a systolic blood pressure of 90 mm Hg
D. femoral artery laceration and a blood pressure of 140/90 mm Hg

D. femoral artery laceration and a blood pressure of 140/90 mm Hg

Gastrointestinal bleeding should be suspected if a patient presents with:

A. dyspnea.
B. hematuria.
C. hematemesis.
D. hemoptysis.

C. hematemesis.

The systemic veins function by:

A. delivering oxygen-poor blood to the capillaries.
B. returning deoxygenated blood back to the heart.
C. delivering deoxygenated blood to the capillaries.
D. returning oxygen-rich blood back to the left atrium.

B. returning deoxygenated blood back to the heart.

Perfusion is MOST accurately defined as the:

A. circulation of blood within an organ in adequate amounts to meet the body's metabolic needs.
B. effective removal of carbon dioxide and other metabolic waste products from the body's cells.
C. ability of the systemic arteries to constrict as needed to maintain an adequate blood pressure.
D. effective transfer of oxygen from the venules across the systemic capillary membrane walls.

A. circulation of blood within an organ in adequate amounts to meet the body's metabolic needs.

Significant vital sign changes will occur if the typical adult acutely loses more than ______ of his or her total blood volume.

A. 15%
B. 20%
C. 5%
D. 10%

B. 20%

Hypoperfusion is another name for:

A. cyanosis.
B. hypoxemia.
C. cellular death.
D. shock.

D. shock.

As red blood cells begin to clump together to form a clot, __________ reinforces the clumped red blood cells.

A. fibrinogen
B. fibrin
C. plasminogen
D. plasma

A. fibrinogen
