Which of the following body systems or components is the least critical for supplying and maintaining adequate blood flow to the body?
An effectively pumping heart
An intact system of blood vessels
Adequate blood in the vasculature
The filtering of blood cells in the spleen
Capillaries link the arterioles and the:
venules
aorta
veins
cells
Hypoperfusion is another name for:
shock
cyanosis
hypoxemia
cellular death
Perfusion is most accurately defined as the:
effective transfer of oxygen from the venules across the systemic capillary membrane walls.
ability of the systemic arteries to constrict as needed to maintain an adequate blood pressure
effective removal of carbon dioxide and other metabolic waste products from the body’s cells
circulation of blood within an organ in adequate amounts to meet the body’s metabolic needs
Which of the following organs can tolerate inadequate perfusion for two to three hours?
Brain
Heart
Kidneys
Skeletal muscle
An organ or tissue might better resist damage from hypoperfusion if the:
body’s demand for oxygen is markedly increased
body’s temperature is considerably less than 98.6°F (37.0°C)
systolic arterial blood pressure is at least 60 mm Hg
heart rate is maintained at more than 100 beats/min
Significant vital sign changes will occur if the typical adult acutely loses more than ______ of his or her total blood volume
5%
10%
15%
20%
The ability of a person’s cardiovascular system to compensate for blood loss is most related to:
his or her baseline blood pressure
the part of the body injured
how rapidly he or she bleeds
how fast his or her heart beats
A fractured femur can result in the loss of ______ or more of blood into the soft tissues of the thigh
250 mL
500 mL
1 L
2 L
In older patients, the first indicator of nontraumatic internal bleeding might be:
weakness or dizziness
a low blood pressure
diaphoresis and pale skin
a heart rate over 120 beats/min
Gastrointestinal bleeding should be suspected if a patient presents with:
dyspnea
hematuria
hemoptysis
hematemesis
In nontrauma patients, an early indicator of internal bleeding is:
a rapid, thready pulse
rapid, shallow breathing
dizziness upon standing
a decreasing blood pressure
Most cases of external bleeding from an extremity can be controlled by:
elevating the injured extremity
packing the wound with gauze
compressing a pressure point
applying local direct pressure
Which of the following splinting devices would be most appropriate to use for a patient who has an open fracture of the forearm with external bleeding?
Air splint
Vacuum splint
Sling and swathe
Cardboard splint
Bleeding from the nose following head trauma:
is a sign of a skull fracture and should not be stopped
should be controlled by packing the nostril with gauze
should be assumed to be caused by a fractured septum
is usually due to hypertension caused by the head injury
Internal bleeding into a fractured extremity is most often controlled by:
applying a tourniquet
splinting the extremity
keeping the patient warm
applying chemical ice pack
Hypovolemic shock occurs when:
the clotting ability of the blood is enhanced
low fluid volume leads to inadequate perfusion
the patient’s systolic BP is less than 100 mm Hg
at least 10% of the patient’s blood volume is lost
The severity of bleeding should be based on all of the following findings, except:
systolic blood pressure
poor general appearance
the mechanism of injury
clinical signs and symptoms
External bleeding from a vein is relatively easy to control because:
veins carry deoxygenated blood
veins hold smaller blood volume
veins are under a lower pressure
blood typically oozes from a vein
Early signs and symptoms of intra-abdominal bleeding include:
bruising only
pain and distention
widespread ecchymosis
significant hypotension
