Ch. 26 Flashcards
A fractured femur can result in the loss of ____ or more of blood into the soft tissues of the thigh.
-500mL
-250mL
-1L
-2L
1L
Capillaries link the arterioles and the:
-Aorta
-Cells
-Venules
-Veins
Veins
External bleeding from a vein is relatively easy to control because:
-Veins are under a lower pressure
-Vines carry deoxygenated blood
-Veins hold smaller blood volume
-Blood typically oozes from a vein
Veins are under a lower pressure
Gastrointestinal bleeding should be suspected if a patient presents with:
-Hematuria
-Hemoptysis
-Hematemesis
-Dyspnea
Hematemesis
Hypoperfusion is another name for:
-Hypoxemia
-Cellular death
-Cyanosis
-Shock
Shock
Hypovolemic shock occurs when:
-Low fluid volume leads to inadequate perfusion
-The patient’s systolic BP is less than 100 mm Hg
-The clotting ability of the blood is enhanced
-At least 10% of the patient’s blood volume is lost
Low fluid volume leads to inadequate perfusion
Most cases of external bleeding from an extremity can be controlled by:
-Applying local direct pressure
-Elevating the injured extremity
-Packing the wound with gauze
-Compressing a pressure point
Applying local direct pressure
Perfusion is most accurately defined as the:
-Circulation of blood within an organ in adequate amounts to meet the body’s metabolic needs
-Effective removal of carbon dioxide and other metabolic waste products from the body’s cells
-Ability of the systemic arteries to constrict as needed to maintain an adequate blood pressure
-Effective transfer of oxygen from the venues across the systemic capillary membrane walls
Circulation of blood within an organ in adequate amounts to meet the body’s metabolic needs
The severity of bleeding should be based on all of the following findings, except:
-Systolic blood pressure
-Poor general appearance
-Clinical signs and symptoms
-The mechanism of injury
Systolic blood pressure
Which of the following organs can tolerate inadequate perfusion for two to three hours?
-Brain
-Skeletal muscle
-Heart
-Kidneys
Skeletal muscle
