Red blood cells Circulation of blood within an organ or tissue in adequate amounts to meet the cells' oxygen, nutritional, and waste-removal needs is termed _______. perfusion Which organ or organ system has the greatest tolerance for lack of perfusion (shock)? Gastrointestinal system Hypovolemic shock occurs when: the body cannot compensate for rapid blood loss. Significant vital sign changes will occur if the typical adult acutely loses more than ______ of his or her total blood volume. 20% The severity of bleeding should be based on all of the following findings, EXCEPT: systolic blood pressure. Which of the following statements regarding hemophilia is correct? Patients with hemophilia may bleed spontaneously. In older patients, the first indicator of nontraumatic internal bleeding may be: weakness or dizziness. A 67-year-old male presents with weakness, dizziness, and melena that began approximately 2 days ago. He denies a history of trauma. His blood pressure is 90/50 mm Hg and his pulse is 120 beats/min and thready. You should be MOST suspicious that this patient is experiencing: gastrointestinal bleeding. Following blunt trauma to the abdomen, a 21-year-old female complains of diffuse abdominal pain and pain to the left shoulder. Your assessment reveals that her abdomen is distended and tender to palpation. On the basis of these findings, you should be MOST suspicious of injury to the: spleen. A young male was shot in the abdomen by an unknown type of gun. He is semiconscious, has shallow breathing, and is bleeding externally from the wound. As you control the external bleeding, your partner should: assist the patient's ventilations. If direct pressure fails to immediately stop severe bleeding from an extremity, you should apply: a tourniquet proximal to the injury. 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 A 43-year-old man is experiencing a severe nosebleed. His blood pressure is 190/110 mm Hg and his heart rate is 90 beats/min and bounding. Preferred treatment for this patient includes: pinching the patient's nostrils and having him lean forward. Which of the following findings would be the MOST significant when assessing a patient with possible internal bleeding? The patient takes rivaroxaban (Xeralto). Internal bleeding into a fractured extremity is MOST often controlled by: splinting the extremity. Whether you are using a commercial device or a stick and triangular bandage as a tourniquet, it is important to remember that: the tourniquet should only be removed at the hospital because bleeding may return if the tourniquet is released. Which of the following body systems or components is the LEAST critical for supplying and maintaining adequate blood flow to the body? The filtering of blood cells in the spleen The systemic veins function by: returning deoxygenated blood back to the heart. The smaller vessels that carry blood away from the heart and connect the arteries to the capillaries are called the: arterioles. Blood stasis, changes in the vessel wall, and certain medications affect the: ability of the blood to effectively clot. Which of the following occurs after tissues are injured? Platelets collect at the injury site Which of the following organs can tolerate inadequate perfusion for 2 to 3 hours? Skeletal muscle An organ or tissue may be better able to resist damage from hypoperfusion if the: body's temperature is considerably less than 98.6°F (37.0°C). An infant with a total blood volume of 800 mL would start showing signs of shock when as little as ______ of blood is lost. 100 mL The ability of a person's cardiovascular system to compensate for blood loss is MOST related to: how rapidly he or she bleeds.Early signs and symptoms of intra-abdominal bleeding include: Gastrointestinal bleeding should be suspected if a patient presents with: hematemesis.

A patient is bleeding severely from a severed femoral artery high in the groin region. Which of the following would MOST likely control the bleeding? Apply a topical hemostatic agent with direct pressure A 70-year-old man presents with a severe nosebleed. His medical history includes COPD, depression, and a hemorrhagic stroke 3 years ago. His BP is 190/110 mm Hg, his pulse is 100 beats/min, and his respirations are 24 breaths/min. His medications include albuterol, sertraline (Zoloft), and multivitamins. Which of the following is MOST likely causing his nosebleed today? High blood pressure The _____ only require(s) a minimal blood supply when at rest. muscles _____ is inadequate tissue perfusion. Shock Significant blood loss demands your immediate attention as soon as the _____ has been managed. Controlling major external bleeding is always the priority.
